1) Using the 360'-rotating damping control dial, the rangeof shock absorption can be adjusted by the useraccording to the impact velocity.

2) Prepares for another cycle by quickly retrieving the pistonroad with a specially designed spring.

3) Extends the life span of the product by preventing thecorrosion with finishes on the outer cylinder andcorroding the chrome plating on the piston road.

4) The thermal energy is established based on theatmospheric temperature of 20'C.

As a kinetic object with a certain mass collides to the piston, the piston backs up into the inner cylinder to gradually chain the orifice. Then the activating

fluid inside the cylinder is pushed out through the orifice into the outer cylinder and flows into and stored in the top of the inner cylinder through the fluid-

retrieving opening. The excessive activating fluid is temporarily stored in the accumulator.

When the object is removed, the piston quickly retrieves back by a return spring so that the activating fluid flows into the inner cylinder through the check

valve.

Applying the Multiple-Orifice principle, the SB Series is equipped with

multiple orifices on the fixed inner tube and inserted with a long-grooved out

tube so that the out tube can be screwed to adjust the total cross section.

It not only can be adjusted according to changes of the shock energy, but

also indicates the size of the energy from 0 to 8 according to the degree of

the openness.

Adjustable Shock Absorber

It refers to the products with fixed orifices produced by unifying the

advantages of the Hydro Shock and the Adjustable Shock Absorber. It not

only absorbs a wider range of shock energy, but also emits the shock energy

as heat energy more efficiently.

Also, this specially designed orifice that does not require adjustments

maintains the pressure evenly throughout the changes of the shock energy to

stop the kinetic object softly.

Principles and Structures of the Shock Absorber

Graph①shows the ideal deceleration while maintaining thelowest impact force,

②shows the low effective state of the self-compensator Shock Absorbers,

③shows the high effective weight state of the self-compensator Shock Absorbers and

④shows a dashpot.

Comment) •The outer measurements are subject to change for improvements withoutnotifications.

The Effective Weight refers to the actual amount of shock energy

absorbed by the Shock Absorber from the moment the kinetic

object collides to the Shock Absorber until it stops. As shown in

Illustration ⓐ, when the actual mass of the kinetic object is minor

but the impact velocity is considerable (faster than 3m/sec), the

resistance increases soon after the collision. Therefore, it is

necessary to increase the cross section of the orifice.

As shown in Illustration ⓑ, when the impact velocity is very slow

(slower than 0.5m/sec) but the mass is considerably heavy or has

an additional propelling force, the resistance increases at the end

of the stroke. Therefore, it is necessary to decrease the cross

section of the orifice.

A) Light Mass and Fast Velocity

Resistance / Increase the cross section of the orifice / Stroke

B) Slow Velocity and Heavy Mass

Resistance / Decrease the cross section of the orifice / Stroke

As shown in Illustrations ①, ②, ③ and ④, even though

the kinetic objects have equal mass and velocity, the

actual shock energy of the Shock Absorber changes

significantly depending on the addition of the additional

propelling force and on the location of the Shock

Absorber.

First, when comparing examples ① and ②, it is shown

that the shock energy of ② is 1.5 times that of ①,

because ② has the addition of the additional propelling

energy.

Also, when comparing examples ③ and ④, it is shown

that the actual shock energy of ③ increases 16 times,

because ③ is located differently although ③ and ④ has

equal amount of kinetic energy.

As explained above, although the mass and the velocity

are equal, the actual shock energy on the Shock

Absorber can change significantly according to each

situation. Therefore, not only the total energy but also the

effective weight has to be considered when selecting a

model.

Precautions

Warning1. In the installation, the Impact body should be perpendicular to the

shock absorber’s axial center.

An angle of deviation that exceeds will place an excessive load

on the bearings, resulting in oil leaks within a short period of

operation.

2. When oscillating impacts are applied, the installation must be

designed so that the direction in which the load is applied is

perpendicular to the shock absorber’s axial center.

The allowable oscillating angle until the stroke end must be O2 <

1”. Here, the minimum installation radius is shown in the table

below. If the angle is in excess of 1”, it may result in oil leakage.

3. It is needed to form a guide when the impact body involve in vibrations.

When it is judged to be involved in vibrations and a force that is

perpendicular to the axis is applied to the piston rod, be sure

that a secure guide must be provided for the impact body.

4. It is needed to consider whether the rigidity of the mounting

frame must be taken into consideration.

If the mounting frame is not rigidly installed, vibrations may occur

in the shock absorber an impact, resulting in bearing wear and

damage. It is needed to apply the following formula to calculate

the force that is applied to the mounting frame:

Caution1. The maximum absorption energy indicated in the specifications forboth Series RB and RBL cannot be brought into full play unless theentire stroke is used.

2. The contact surface of the impact body with which the pistonrod comes in contact must be highly rigid.In the case whthout a cap, a high surface compression load isapplied to the contact surface of the impact body with which thepiston rod comes in contact. Therefore, the contact surface must behighly rigid(hardness of HRC35 or more).

3. Be aware of the return force of the impact body. If used in a conveyou drive, affer the shock absorber has absorbedenergy, it could be pushed back by the spring that is built in. Referto the column for the spring force in the specifications.

Caution1. Be sure to check whether the retaining nut is loosed.

If it is used in a loosed state, the shock absorber could become damaged.

2. Be sure to check any abnormal impact sounds or vibrations.

In event that the impact sounds or vibrations are abnormally high, the

shock absorber may have reached the end of its service life. In this case,

it is preferred to replace the shock absorber. The continuation of this state

may cause equipment damage.

3. Be sure to check the cap for any cracks or wear. In event that the shock

absorber comes with a cap, the cap could wear first. So as to prevent

the impact body from damage, it is preferred to replace the cap often.

Warning1. Exposing the shock absorber to machining oil, water, or dust should

be avoided.

Under the condition that fluids such as machining oil or water are

present in atomized form or come in direct contact with the piston

rod, or in which dust could adhere to the piston rod, the use of

series RB should be avoided. Otherwise, malfunction may result.

2. Operating the shock absorber in an environment that poses the

risk of corrosion.

Be sure to see the respective structural drawing for the type of

material used in the shock absorber.

3. The use of the shock absorber in a clean room should be avoided.

Since the clean room may be contaminated thereby.

WarningBe sure to check the power supply to the equipment and verify that

the equipment has stopped prior to performing torque installation,

removal, or stroke adjustment.

Caution1. The torque of mounting nut should be tightened as follows.

In event that the tightening torque applied to the nut is in excess of

the value given above, the shock absorber itself may be damaged.

2. Scratchingthe sliding portion of the piston rod or the outside

should be avoided.

If it is failed to check this precaution, the sliding potion of the piston

rod, or damage the seals may be scratched or gouged, resulting in

leakage and malfunction. Furthermore, damaging the outer side of

threaded portion of the outer tube may prevent the shock absorber

from being mounted onto the frame, or its informal components could

deform, resulting ina malfunction.

3. Turning the screw on the bottom of the body should be avoided.

It is not an adjustment screw, as this will cause oil leakage.
