Designing with the Series 320 Vibration Isolation Bearing

How much weight can I support with the VIB320?

Each bearing will isolate a range of payloads beginning with payloads as low as 8 lbs (3.6 Kg) and as heavy as 180 lbs (82 Kg) depending upon the particular part number selected. (Please see VIB320: Size Selection Chart for a complete list of bearings available by payload carrying capacity.)

A typical tool con� guration will require four VIB bearings so the maximum payload that can be isolated with the Series 320 VIB is 720 lbs. (528 Kg) (4 x 180 = 720/4 x 82 = 528). (If you need to isolate a heavier payload, ask about our Vibration Isolation Bearings for heavier payloads.)

How does the VIB mechanically operate?

� e bearing de� ects vertically when a payload is placed on the bearings. � e amount of de� ection is a function of the payload on each bearing. � e bearings also de� ect horizontally (when under load) if a horizontal force is applied above or below the plane of isolation.

� e Series 320 Vibration Isolation Bearing (bearings, VIB or VIB320) is a mechanical, passive device that attenuates the transmission of vibrations. Since the bearings are passive and mechanical, they are easy to design into equipment such as a metrology tool or other precision inspection or manufacturing equipment.

� e purpose of this document is to help a tool designer understand how to use the VIB in the design of a tool. We approach this topic in a Q&A format. Before beginning the discussion, we will de� ne a few terms used in this document.

Isolated plate. In a typical installation, a plate of some sort will be mounted on four bearings. � e sensitive equipment (a microscope for instance) will be mounted to the top of this plate. It is the equipment and/or operations on the top of this plate that must be isolated from vibrations. � is plate can be steel or aluminum, a piece of granite or a honeycomb panel, for instance. � roughout this document, regardless of the material used, it will be referred to as a “plate” or an “isolated plate”.

Plane of isolation. � e imaginary plane created by the four bearings.

What is the height of the VIB320 bearing?

� e height of the bearing without any adapter base plates or leveler attachments is 2.35” (57mm) before a payload is placed on the bearing. Once the bearing is under load, it will de� ect and will e� ectively isolate within a range of de� ection. � e Size Selection Chart for the Series 320 VIB lists the minimum weight required to de� ect the bearing enough before it will isolate – this is called the Minimum Payload – and the maximum amount of weight the bearing can support before the bearing is over compressed and will not e� ectively isolate – this is called the Maximum Payload.

Within the operating range, the height of the Series 320 bearing will range between 1.85” (47 mm) and 2.25” (57 mm) tall, before adding the additional height for the adapter plates and the Leveler Attachments. Each Base Adapter Plate adds ¼” (6 mm) to the height.

Two factors a� ect the height of the bearing when in use. First, the bearing de� ects +/- 0.20” (5mm) from its mid-de� ection point. Secondly, both the Leveler Stud and the Leveler Bar Attachments can be adjusted +/- 0.25” (6.35mm) from is mid-point setting. � erefore, while there is no guarantee that each bearing will de� ect to the same degree, since each Leveler Attachment is vertically adjustable, the isolated plate above the bearings can be raised or lowered to insure it is level.

� e following Installation Guidelines and details are attached:

• Working Height of the VIB320 with the Leveling Bar Attachment

• Installation Guidelines for the Series 320 VIB with the Leveling Bar Attachment

• Working Height of the Series 320 Bearing with the Leveling Stud Attachment

• Installation Guidelines for the Series 320 VIB with the 6 mm Leveling Stud Attachment

• Installation Guidelines for the Series 320 VIB with the 10 mm Leveling Stud Attachment

What is the bearing’s shear capacity?

� e Series 320 Vibration Isolation bearing is designed to support the vertical load of the isolated payload and to attenuate the transmission of vibrations. It is not designed with signi� cant capacity to withstand the potential large shear force that can occur in transit, loading and unloading, or during an earthquake. Consequently, a method of locking the bearing should be designed into the tool for protection during transit, loading and unloading. Vistek can advise as to how to design this feature. Furthermore, a snubber or other method of preventing shear displacement of the isolated payload during a seismic event should be designed into the tool.

� e diagram on the following page will help explain what steps must be taken to secure the tool during transportation.

How are the bearings mounted to the tool?

� e VIB is mounted to the top of a tool frame or other supporting structure with one of three Adapter Plates – a square plate, a round plate or a rectangular plate. Details showing the bolt-hole pattern are available for all three options. � ere is no functional di� erence between the square, round and rectangular base adapter plate options. � e VIB is bolted to the adapter plate when Vistek ships a bearing, and the adapter plate is bolted to the tool frame when a bearing is installed.

� e following detail is of the square adapter plate. Contact Vistek for complete details.

How is the isolated plate mounted onto the top of the bearings?

� ere are two Leveler Attachments used to bolt the isolated plate to the top of the bearing - the Leveler Bar, and the Leveler Stud. Each option provides +/- .20” (5 mm) vertical adjustment. Contact Vistek for details of each attachment option.

How to secure the Series 320 Vibration Isolation Bearing during tool transportation

� is diagram is intended to illustrate a typical tool design in that in every tool in which vibration isolation bearings are used, there is a plane of isolation. � e portion of the tool above the plane of isolation will move relative to the portion of the tool beneath the plane of isolation. It is imperative that steps be taken to secure the portion of the tool above the plane of isolation so that it will not move relative to the portion beneath the plane of isolation during transportation. � e locking screw shown in the above diagram is simply one method. � e method that works best for you will depend upon the speci� cs of your tool design.

Series 320-Vibration Isolation BearingsHow they work

The VIB320 bearings work within a defined range of weight under which the bearings deflect or compress. When the bearing is under compression the gap ranges from .56” to .1” and the payload is isolated in that entire range. We send a gap tool that is .56” on one side and .1” on the other. If it fits in the gap with the .56” the bearing does not have enough weight on it, on the other hand if the .1” does not fit, it is over-loaded.

VISTEK’S VIBRATION ISOLATION BEARINGS - - HOW THEY WORK Vistek Vibration Isolation Bearings (VIBs) filter the transmission of micro- vibrations in six degrees of freedom. VIBs cut off the transmission of vibrations at low frequencies. These bearings provide superior performance without the inconvenience, bulk and expense of air isolation or piezzo electric systems. VIBs are passive and mechanical and do not require air hoses, maintenance or supporting hardware. They are scaleable and easily adapted to a wide range of applications. VIBs utilize a proprietary combination of two non-linear springs - - a horizontal spring filter and a vertical spring filter. Horizontal Spring Filter: Steel balls sandwiched between precision raceways form the plane of isolation. Micro-vibrations cause the balls to displace between the two raceways and cut off the transmission of vibrations. The balls that displace between the raceways are restored to the neutral position by the force of gravity, which acts as a non-linear spring. Since the spring force (i.e., the restoring force) is non-linear, it is constant and independent of the frequency and amplitude of the input vibrations. As a result, the oscilating motion of the balls has no “natural” frequency. Rather, the motion has an infinite number of frequencies, one for each increment of displacement. Consequently, resonance between the two halves of the plane of isolation is physically impossible. Therefore, the horizontal spring filter whites out or filters out a broad band of input frequencies and insures a constant level of vibration transmission reduction. Vertical Spring Filter: The isolated instrument is effectively levitated by a quasi-rigid body - - a proprietary, non-linear spring mechanism with near zero tangential stiffness for micro-vibrations. The natural frequency of the spring remains relatively low and constant across a large range of spring compression for which the compression force is matched by the restoring force. In this range, the percentage of vibrations transferred through the spring filter is very low.

SERIES 320 WORKING HEIGHT

Working Height of the VIB320 with the Leveler Bar Attachment Two factors affect the bearings working height. First, the bearing deflects when weight (or payload) is applied. Secondly, the Leveler Bar is threaded into the adapter, and it can be turned into and out of the adapter to level the isolated plate above.

H1 Dimension

• Under insufficient payload, H1 = 2.6” (66mm) • Under excessive payload, H1 = 2.0” (51mm) • Under mid-range loading, H1 = 2.3” (58mm) +/- 0.20” (5mm)

Under insufficient payload, insufficient weight has been applied to deflect the bearing and the bearing will act as a rigid body and will not attenuate vibrations at all. Under excessive payload, there is too much weight causing the bearing to bottom out and act as a rigid body and therefore not attenuate the transmission of the vibrations in the vertical plane. Mid-range loading is the applied weight that will deflect the bearing 50% of its’ potential deflection. The Series 320 bearing can deflect up to 0.4” (10mm) or +/- .2” (5mm) from the mid-range setting and still isolate. Height Adjustment Range in the Leveler Bar Attachment WARNING. Over turning the bearing body in the counter-clockwise direction will back the Leveler Bar out of the adapter. The Leveler Bar is designed so that if a minimum of 0.25” (6.35mm) of the Leveler Bar is threaded into the adapter, then the visible threaded stem of the Leveler Bar is 0.5” (13mm) long. Therefore, the Leveler Bar can be turned to a mid-range setting and adjusted +/- .25” (6.35mm) from this point. H2 Dimension Insufficient payload and Leveler Bar at the mid-point setting, H2 = 3.55” (90mm) +/- 0.25” (6.35mm) Excessive payload and Leveler Bar at the mid-point setting, H2 = 2.95” (80mm) +/- 0.25” (6.35mm). Mid-range loading and Leveler Bar at the mid-point setting, H2 = 3.25” (83mm) +/- 0.25” (6.35mm).

INSTALLATION GUIDELINES

Installation Guidelines for the Series 320 VIB with the Leveling Bar Attachment Isolated plate. In a typical installation, a plate of some sort will be mounted on four bearings. The sensitive equipment (a microscope for instance) will be mountedto the top of this plate. It is the equipment and/or operations on top of this plate that must be isolated from vibrations. This plate can be steel or aluminum, a pieceof granite or a honeycomb panel. Regardless of the material used, it will be referred to as a “plate” or an “isolated plate” in this drawing.

The following instructions are guidelines. Please read all the way through before beginning. Your situation may require a different protocol. 1. Secure the bearings to the underside of the isolated plate. Align mounting holes in Leveler Bar with holes to be drilled into the underside of the isolated plate.

Optional: Turn the Leveler Bar out of the threaded adapter and grease the threads to make leveling the isolated plate easier. 2. Lower the isolated plate onto the tool aligning the mounting holes in the bearing attachment base with the mounting holes on the topside of your tool frame or

other mounting surface. 3. Secure the bearings to the top of the tool frame/mounting surface. Leveling the Isolated Plate Once the bearings are bolted to the tool frame/mounting surface and fixed above to the isolated plate, the isolated plate may be raised or lowered over eachbearing by turning the bearing body.

• Turning the bearing body clockwise raises the height of the isolated plate. • Turning the bearing body counter-clockwise lowers the height of the isolated plate.

WARNING: Over turning the bearing body in the counter-clockwise direction will back the Leveler Bar out of the adapter.

Installation Guidelines for the Series 320 VIB with the ¼-20 Leveling Stud Attachment Isolated plate. In a typical installation, a plate of some sort will be mounted on four bearings. The sensitive equipment (a microscope for instance) will be mounted to the top of this plate. It is the equipment and/or operations on top of this plate that must be isolated from vibrations. This plate can be steel or aluminum, a piece of granite or a honeycomb panel. Regardless of the material used, it will be referred to as a “plate” or an “isolated plate” in this drawing. Plate thickness in this drawing is unspecified

The following instructions are guidelines. Please read all the way through before beginning. Your situation may require a different protocol. 1. Place a nut on Leveler Stud and turn it to the base of the stud. Optional: Place a split washer or Belleville washer on the stud above the nut. 2. Secure the bearings to the underside of the isolated plate by threading the stud into the holes on the underside of the isolated plate. Optional: Grease the

studs to make leveling the isolated plate easier. 3. Lower the isolated plate onto the tool aligning the mounting holes in the bearing attachment base with the mounting holes on the topside of your tool frame or

other mounting surface. 4. Secure the bearings to the top of the tool frame/mounting surface. Leveling the Isolated Plate Once the bearings are bolted to the tool frame/mounting surface and fixed above by being threaded into the isolated plate, the isolated plate may be raised orlowered over each bearing by turning the bearing body.


WARNING: Over turning the bearing body in the counter-clockwise direction will back the Leveler Stud out of the isolated plate.
