Oil Lubrication
LM systems that require oil lubrication are shipped with only anti-rust oil applied. Please indicate
when ordering.
z
The amount of oil to be applied varies depending on the stroke length. For a long stroke,
increase the lubrication frequency or the amount of oil applied so that an oil film is able to form
in the stroke end of the raceway.
z
In environments where coolant may spatter, the lubricant may become mixed with the coolant.
This could result in the lubricant being emulsified or washed away, causing significantly
degraded lubrication performance. In such locations, apply a lubricant with high viscosity
(kinematic viscosity: approx. 68 cst) and high emulsification resistance, and adjust the
lubrication frequency or the amount of the applied lubricant accordingly.
z
For machine tools and similar devices that are subject to heavy loads, require high rigidity, and
operate at high speed, oil lubrication is recommended.
z
Make sure that lubrication oil discharges normally from the ends of the lubrication piping; that
is, the oiling ports that connect to your linear motion system.
