Precautions on Use
2-4

Lubrication

z Thoroughly remove anti-rust oil and feed lubricant before using the product.
z Do not mix different lubricants. Even grease containing the same type of thickening agent
may, if mixed, interact in an adverse manner due to disparate additives or other ingredients.
Check lubricant
z When using the product in locations subject to constant vibrations or in special environments
such as in clean rooms, vacuums, and under low or high temperatures, be sure to use a
lubricant―suitable―for―the―specifications―and―environment.
z When lubricating products, directly coat the raceway surface with lubricant and perform
several warm-up strokes to ensure that the grease permeates the interior.
z 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.
z Excess grease may spatter immediately after lubrication. Wipe off spattered grease as
necessary.
z The properties of the grease deteriorate over time, thereby degrading the lubricity. It is
necessary to inspect and apply the grease in accordance with the usage frequency.
z How often grease should be replenished varies depending on the usage conditions and
environment. Final greasing interval/amount should be set at an actual machine.
