Lubrication Method
There are three methods of lubricating an LM Guide: manual greasing using a grease gun or
manual pump; forced oiling with the aid of an automatic pump; and oil-bath lubrication.
To achieve efficient lubrication, it is necessary to mount the grease nipple or the piping joint
according to the installation direction.

Before Supplying Grease
Check that no foreign materials are adhering to the LM rail. If
any foreign materials remain adhered, they may enter inside
the LM block.
If you find any foreign materials adhered, please wipe them
off with a waste cloth, etc., and then grease the LM block.
Then, as shown in the photo on the right, apply a thin layer of
grease to the LM rail. This reduces abrasion of the dust
prevention seal, and protects the seal.
* When using the LM Guide in an environment where foreign materials can adhere easily to the
LM rail, we recommend taking measures such as using a cover.

Supplying Grease
(1) Stop the equipment and inject one or two shots of grease with
a grease gun from the grease nipple.
(2) Reciprocate a stroke that is five times longer than the overall
length of the LM block.
(3) Repeat (1) and (2) so that sufficient grease is applied to the
raceway up to the stroke end.
* The amount of grease and application frequency will vary
according to the product, the environment, and the usage
conditions.
About five times longer than the overall length of the LM block
Stroke end
* The greasing interval will vary depending on the usage conditions and environment. For normal
use, we recommend greasing the system approximately every 100 km of travel distance.
