The diagrams contained herein are representative examples and may vary from the actual product. z THK will not be liable for the effects resulting from the use of this manual for any reason whatsoever. z This manual also applies to special products, but content specified on the Delivery Specification―Diagram―takes―priority.―... -
Page 4: Applying This Product
Do not use this product for equipment or systems used in life-threatening situations. z Consult THK beforehand when considering using this product for special applications such as in passenger vehicles or in medical, aviation and space, nuclear power, or electrical power equipment or systems. -
Page 5: Precautions On Use
Do not disassemble the product. Do not disassemble z Take care not to drop or strike the Linear Bushing. This could cause injury and damage the product. If the product receives an impact, it could impair the product's functions, even if the product looks intact. -
Page 6: Precautions On Use
A lack of rigidity and accuracy of mounting components may cause the bearing load to localize,―reducing―the―performance―of―the―bearing―significantly.―Therefore,―consider―carefully― the rigidity and accuracy of the housing and base, and the strength of the securing bolts. z If any of the rolling elements fall, discontinue use and contact THK.

Page 7: Lubrication
Grease consistency can vary depending on the temperature. Keep in mind that the Linear Bushing―sliding―resistance―will―be―affected―by―changes―in―consistency. z Following greasing, the stirring resistance of the grease can cause the Linear Bushing to exhibit increased sliding resistance. Before commencing operations, be sure to run the unit through several warm-up cycles to ensure that the grease is adequately integrated and dispersed. -

LMCH-L Clearance between the Outer Cylinder and LM Shaft When using the Linear Bushing in combination with an LM shaft, use normal clearance in ordinary use and a small gap if the clearance is to be minimized. Note 1: If the clearance after installation is to be negative, it is preferable not to exceed the radial clearance tolerance―indicated―in―the―specification―table. -
Page 9: Mounting The Outer Cylinder
Mounting the Outer Cylinder Although the Linear Bushing does not require a large amount of strength for securing it in the LM shaft direction, do not rely only on a press fit to support the nut. For the housing inner-diameter tolerance, see Table 3-1. - Page 10 Assembly Snap Ring for Mounting See Table 3-3 for the models of snap rings to use for securing the Linear Bushing model LM. Note 1: For models indicated in parentheses, use C-shape concentric snap rings. Note 2: Table 3-3 commonly applies to models LM, LM-GA, LM-MG, and LM-L.
- Page 11 (-AJ), use a housing that allows adjustment of the outer diameter to facilitate adjustment of the clearance between the Linear Bushing and the LM shaft. Positioning the Linear Bushing slit at a 90° angle to the housing slit will apply uniform deformation in the Figure 3-4 Mounting a circumferential direction.

Washer SK30 Reference surface Mounting the Linear Bushing z Mounting Model SC (SL) Since models SC and SL can be attached from the top or bottom by simply tightening the bolts, the installation time can be shortened. (Figure 3-6) Figure 3-6 Mounting Model SC (SL) - Page 13 When using the Linear Bushing, make sure the load is evenly distributed across the entire ball raceway. In particular, if a moment load is to be applied, use two or more Linear Bushing units on the same LM shaft and secure an adequately large distance between the Linear Bushings.

Page 15: Lubrication
To optimize Linear Bushing functions, provide lubrication appropriate to the usage conditions. Grease Lubrication When installing onto an LM shaft, apply grease to the rows of balls in the Linear Bushing. Then, depending on the usage state, either apply as described above when appropriate, provide a housing as shown in Figure 4-1, or apply grease to the LM shaft. - Page 16 Lubrication Normally, relubricate using the same grease type and through the lubrication hole or grease nipple provided on the Linear Bushing. Mixing different types of grease may deteriorate the system’s performance due to increased consistency or other such factor. Lubricant...
