Miniature Linear Guides
2Installation of slide rail

*When there is a reference surface in the base mounting surface
Before assembly, please remove the burrs and dirt on the mechanical mounting surface of the linear
guide.
Place the slide rail slowly on the base mounting surface, and then temporarily fasten the slide rail 2
while making it contact with the base reference surface.
When subjected to impact, vibration, heavy load or requiring high precision, the fixing methods in
Figures 1 to 3 are recommended.
Use a torque wrench to tighten the mounting bolts to the specified torque. (Refer to Table 1 for the Bushings / Oil Free Bushings Linear Guides / Linear
specified torque.)

Place the slide rail slowly on the base mounting surface, and then temporarily fasten the mounting
bolts. Bushings Linear
It is equipped with a straightedge almost parallel to the temporarily fastened slide rail.
Based on the straightedge, use a dial meter as shown in Figure 4 to measure the parallelism with the
slide rail while reinforcing it. P.139
Use a torque wrench to tighten the mounting bolts to the specified torque.
The secondary rail can be installed in the same straightedge method as the primary master rail, or
by using the primary rail as a datum reference as shown in Figure 5. In either method, use a dial Bushings Oil Free
indicator to measure the parallelism while the rail is being.

2About maintenance (supply of grease)

* Grease forms an oil film on the surface of the linear guide ball and rolling surface to effectively reduce
friction and prevent sintering.
Decrease and aging of grease will greatly affect the life of the linear guide, so please add grease at the
right time according to the service conditions.
MISUMI's linear guides are sealed with the greases listed below at the time of shipment, so they can be
used directly.
*Miniature: Lithium Soap based Grease (Multemp Grease PS2)
* Recommended grease filling interval: Usually every 3 months
Depending on the operating environment, the grease injection interval must be shortened appropriately
when the grease is aging and dirty.
