Construction and Features

Fig. 2 Load-Bearing Capacity of Type KR

Fig. 1 Construction of LM Guide Actuator KR

Four-way Equal LoadLoad-bearing ball races are arranged with two on eachside, thus constituting a double-row angular-contactdesign. As this design can bear an equal rated load in allfour directions (upward and downward, right and left),the mounting direction of the unit is not limited. The LMGuide Actuator is therefore suited for applications wherethe loading direction is not fixed, as in the motion of aCartesian coordinate robot arm etc.

The one-piece structure of the LM Guide, with a U-shaped outer rail and the ball screw in the center of theinner block, provides high rigidity and excellent accura-cy and requires minimal installation space to combinerigid and precise functioning with a minimum size.

Ball races are arranged at a contact angle of 45° in rela-tion to one another so that each race of balls bears anequal load rating on the inner block in all four directions:radial, reverse-radial, and the two lateral directions.Thus, this type can be used in any installation direction.

High RigidityUnlike conventional LM Guide models, the LM GuideActuator has adopted an outer-rail structure, which pro-vides far greater rigidity against overhung loads.

The U-shaped cross section of the rail contributes toweight reduction and minimises deflection. Thus, theLM Guide Actuator can support a load on one side aswell as on both.

High AccuracyThe four raceways for loaded balls, which are formedinto a circular-arc groove, allow balls to roll smoothlyeven under a preload. Preloading eliminates clearances,provides high rigidity for the guideway, and minimisesfluctuations in frictional resistance due to a fluctuatingload. As a result, a high feeding accuracy in sub-micronscan be obtained.

Load Rating

LM GuideType KR can bear loads in all four directions: radial,reverse-radial, and the two lateral directions. The basicload ratings of type KR are equal in all four directions(radial, reverse-radial and the two lateral directions). Thevalues are given in Table 2.

Ball ScrewBecause of the construction where the ball screw isdriven through the inner block, type KR can bear anaxial load. The values of basic load rating are presentedin Table 2.

Support BearingDue to its construction, with an angular bearing assem-bled in housing A type KR can bear an axial load. Thevalues for the basic load rating are given in Table 2.

LM GuideThe equivalent load for type KR when loads are exertedon its LM Guide in all four directions simultaneously canbe obtained using the following equation:

PE = PR (PL) + PT

wherePE : equivalent load [N]

• In the radial direction• In the reverse-radial direction• In two lateral directions

PR : radial load [N]PL : reverse-radial load [N]PT : lateral load [N]

Service Life

LM Guide Actuator KR consists of an LM Guide, a ballscrew and support bearings. The service lives of thesecomponents can be calculated using the values for thebasic dynamic load rating given in Table 2.

Calculating Service Life

1) LM Guide

L : nominal life (km)(This refers to the total running distance that90% of identical LM Guide Actuator units in agroup, when operated independently underthe same conditions, can achieve withoutdeveloping flaking.)

C : basic dynamic load rating (N)PC : calculated load applied (N)fW : load factor (see Table 5)fC : contact factor (see Table 4)

• When KR’s are used with close-linked double innerblocks and are subjected to a moment, calculate theequivalent load by multiplying the moment exertedby an equivalent factor selected from those given inTable 6.

Pm = K�M

Pm : equivalent load (per block) (N)K : moment-equivalent factorM : developed moment (N�mm)

(If three or more blocks are used in a system ortwo blocks are separated from one another,please contact us.)

Particularly when moment MC is exerted on type KR-Bor D:

Pm = Kc � Mc2

fc � CL = ( )3 � 50 [km]

fw �Pc

• When radial load (P) and a moment are exerted simul-taneously, calculate the service life using the follow-ing equation:

PE = Pm + P

PE : total equivalent radial load (N)

Once nominal life (L) is obtained from this calculation,the service life in hours can be calculated using the fol-lowing equation, if the stroke length and number of rec-iprocal operations are constant:

Lh : service life in hours (h)ls : stroke length (mm)n1 : number of reciprocal operations

per minute (min–1)

2) Ball Screw and Support Bearing

L : nominal life (rev.)(This refers to the total number of revolutionsthat 90% of ball screw units (support bearing)in a group, when operated independentlyunder the same conditions, can achieve with-out developing flaking.)

Ca : basic dynamic load rating (N)Fa : axial load (N)fW : load factor (see Table 5)

Once nominal life (L) is obtained from this calculation,the service life in hours can be calculated using the fol-lowing equation, if the stroke length and number of rec-iprocal operations are constant:

Lh : service life in hours (h)�s : stroke length (mm)n1 : number of reciprocal operations

per minute (min–1)� : Ball Screw lead (mm)

Lh = L � 106

Lh = L � �2 � �s � n1 � 60

Moment-equivalent-factor (LM Guide)In a LM Guide operating subjected to a moment, theload distribution cannot be uniform, resulting in the exer-tion of an excessive load in localized areas. In such acase, calculate the load by multiplying the moment valueby a moment-equivalent factor chosen from Table 6.

Maximum Running Velocity and Production Limit LengthThe maximum running velocity of KR type actuators is restricted by the critical velocity and the DN value of the ball screw,regardless of the maximum motor speed. Keep this in mind, particularly when using this type of actuator at high speed.In this case, the production limit length is represented by the LM rail length.

LubricationTo obtain the full function of a linear-motion system, lubrication is essential. Use of such a system without lubricationaccelerates wear on the rolling parts, thereby decreasing the service life. Normally, grease is fed approximately every100 km of running distance, but the interval depends on the operating conditions. It is advisable that the greasing inter-val is set based on the results of an initial check.Recommended grease: KR15 AFF

KR20 ~ 26: AFAKR30H ~ KR65: AFB

For LM-Guide Actuators to be used in a clean room, low-dust-generation AFE grease is available at . Pleasecontact if such grease is required.

The accuracy of type KR comprises positioning-accura-cy reproducibility, positioning accuracy, backlash, andrunning parallelism.

1. Positioning-Repeatability 3. Backlash

Using the maximum stroke as the reference length,measure the distance actually traveled from the refer-ence position, and determine the maximum differencebetween a measurement and target value. Express thepositioning accuracy using the absolute value of thismaximum difference.

2. Positioning Accuracy

Place a straight edge on a surface plate to which a unitof type KR is mounted. Using a test indicator, measurethe parallelism over the entire inner-block stroke. Takethe maximum of the measurements within the stroke asthe parallelism.The brackets required to mount LMGuide Actuator type KR have been standardized. Madeof aluminum, the brackets are lightweight in order tominimize inertia.

4. Running parallelism

Using the feeder, move the inner block slightly. Definethe reading of the test indicator at this time as the refer-ence position. Without using the feeder, apply a load tothe inner block in order to move it from this referenceposition in the same direction as above (table-feedingdirection). Release the load and allow the inner block toreturn. Measure the distance between the returned-block position and the reference position.

Measure the same in the middle of the stroke and atboth ends. Take the maximum of the measurementsthus obtained as the backlash.

Accuracy Standards

Backlash

Move the inner block from a starting point and stop it ata given point, measuring the stopped position. Repeatthis measurement in the same direction as above seventimes each in the middle of the stroke and at both ends.Take the maximum values at each stopping position asthe measurements being sought. Divide the maximumdifference among these maximum values by 2. Definethe value thus obtained as the positioning repeatability,attaching “±” thereto.

KR15The evaluation methods for the accuracy grades mustconform to Standards. The starting torque must bemeasured with lithium-soap-based grease No. 2 applied.For KR20 and 26, however, AFA Grease must be applied. ForKR15 AFF Grease must be sealed in. When high-vis-cosity grease such as vacuum grease or clean-roomgrease is used, measurements may exceed the standardspresented here. Therefore, the motor to be used must be cho-sen carefully.

Precautions on Use• HandlingDo not drop the product or subject it to impact, as doing so may damage it. Therefore, great care should be exercised in its handling.Unauthorized disassembly of the product could lead to contamination by foreign matter and impair the precision. Therefore, disassembly should notbe performed unless absolutely necessary.At high rotational speeds, the ballscrew causes resonance due to the characteristic frequency of the screw shaft, which may make operation impos-sible. The shaft speed should be therefore set at a level below the resonant point (critical speed).Please consult .

• Operating Temperature RangeDo not use this product at 80 °C or higher. If your system requires a temperature of 80 °C or higher, contact .

• LubricationA certain lubrication is absolutely necessary for the operation of the LM Guide Actuator KR. Otherwise, it will be damaged before it reaches its pro-jected service life. Therefore, please take care about the following points:- Before operation the anti-corrosion oil must be removed and the LM Guide Actuator KR lubricated.- The usage of different lubricants must be avoided.- The lubricant intervals should correspond to the operation necessities and to the environment surroundings.- When used under special environment, including in locations subject to continual vibration, in a clean room, under a vacuum, and at low or high

temperatures, contact .
