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 each
side, thus constituting a double-row angular-contact
design. As this design can bear an equal rated load in all
four directions (upward and downward, right and left),
the mounting direction of the unit is not limited. The LM
Guide Actuator is therefore suited for applications where
the loading direction is not fixed, as in the motion of a
Cartesian 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 the
inner block, provides high rigidity and excellent accura-
cy and requires minimal installation space to combine
rigid 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 an
equal 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 Rigidity
Unlike conventional LM Guide models, the LM Guide
Actuator has adopted an outer-rail structure, which pro-
vides far greater rigidity against overhung loads.
The U-shaped cross section of the rail contributes to
weight reduction and minimises deflection. Thus, the
LM Guide Actuator can support a load on one side as
well as on both.

High Accuracy
The four raceways for loaded balls, which are formed
into a circular-arc groove, allow balls to roll smoothly
even under a preload. Preloading eliminates clearances,
provides high rigidity for the guideway, and minimises
fluctuations in frictional resistance due to a fluctuating
load. 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 basic
load ratings of type KR are equal in all four directions
(radial, reverse-radial and the two lateral directions). The
values are given in Table 2.
Ball ScrewBecause of the construction where the ball screw is
driven through the inner block, type KR can bear an
axial load. The values of basic load rating are presented
in Table 2.
Support BearingDue to its construction, with an angular bearing assem-bled in housing A type KR can bear an axial load. The
values for the basic load rating are given in Table 2.
LM GuideThe equivalent load for type KR when loads are exerted
on its LM Guide in all four directions simultaneously can
be obtained using the following equation:
PE = PR (PL) + PT
where
PE : 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 ball
screw and support bearings. The service lives of these
components can be calculated using the values for the
basic dynamic load rating given in Table 2.
Calculating Service Life
1) LM Guide
L : nominal life (km)
(This refers to the total running distance that
90% of identical LM Guide Actuator units in a
group, when operated independently under
the same conditions, can achieve without
developing 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 KRs are used with close-linked double inner
blocks and are subjected to a moment, calculate the
equivalent load by multiplying the moment exerted
by an equivalent factor selected from those given in
Table 6.
Pm = KM
Pm : equivalent load (per block) (N)
K : moment-equivalent factor
M : developed moment (Nmm)
(If three or more blocks are used in a system or
two blocks are separated from one another,
please contact us.)
Particularly when moment MC is exerted on type KR-B
or D:
Pm =Kc Mc
2
fc CL = ( )3 50 [km]fwPc
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 (min1)
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 independently
under 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 (min1)

Moment-equivalent-factor (LM Guide)
In a LM Guide operating subjected to a moment, the
load distribution cannot be uniform, resulting in the exer-
tion of an excessive load in localized areas. In such a
case, calculate the load by multiplying the moment value
by a moment-equivalent factor chosen from Table 6.
KA, KB, and KC represent the moment-equivalent factors
in directions MA, MB, and MC, respectively.

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 lubrication
accelerates wear on the rolling parts, thereby decreasing the service life. Normally, grease is fed approximately every
100 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: AFA
KR30H ~ KR65: AFB
For LM-Guide Actuators to be used in a clean room, low-dust-generation AFE grease is available at . Please
contact if such grease is required.

The accuracy of type KR comprises positioning-accura-
cy reproducibility, positioning accuracy, backlash, and
running 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 difference
between a measurement and target value. Express the
positioning accuracy using the absolute value of this
maximum difference.
2. Positioning Accuracy
Place a straight edge on a surface plate to which a unit
of type KR is mounted. Using a test indicator, measure
the parallelism over the entire inner-block stroke. Take
the maximum of the measurements within the stroke as
the parallelism.The brackets required to mount LM
Guide Actuator type KR have been standardized. Made
of aluminum, the brackets are lightweight in order to
minimize inertia.
4. Running parallelism
Using the feeder, move the inner block slightly. Define
the reading of the test indicator at this time as the refer-
ence position. Without using the feeder, apply a load to
the inner block in order to move it from this reference
position in the same direction as above (table-feeding
direction). Release the load and allow the inner block to
return. Measure the distance between the returned-
block position and the reference position.
Measure the same in the middle of the stroke and at
both ends. Take the maximum of the measurements
thus obtained as the backlash.
Accuracy Standards
Backlash
Move the inner block from a starting point and stop it at
a given point, measuring the stopped position. Repeat
this measurement in the same direction as above seven
times each in the middle of the stroke and at both ends.
Take the maximum values at each stopping position as
the measurements being sought. Divide the maximum
difference among these maximum values by 2. Define
the value thus obtained as the positioning repeatability,
attaching thereto.

KR15
The evaluation methods for the accuracy grades must
conform to Standards. The starting torque must be
measured with lithium-soap-based grease No. 2 applied.
For KR20 and 26, however, AFA Grease must be applied. For
KR15 AFF Grease must be sealed in. When high-vis-
cosity grease such as vacuum grease or clean-room
grease is used, measurements may exceed the standards
presented here. Therefore, the motor to be used must be cho-
sen carefully.

Precautions on Use Handling
Do 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 not
be 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 Range
Do not use this product at 80 C or higher. If your system requires a temperature of 80 C or higher, contact .
Lubrication
A 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 .
