Grease is not pre-packed in the IKO CRWG series, CRWG...H series and CRW series, so please perform adequate lubrication as needed.

Both of oil lubrication and grease lubrication are available in the IKO CRWG series, CRWG..H series and CRW series. Generally, oil lubrication should be selected for high speed or low frictional resistance, and grease lubrication for low speed. For grease lubrication, use of high-quality lithium-soap base grease is recommended. For light load and low speed, apply grease or oil to raceway, rack and pinion gear first and then reapply accordingly. However, the structure as indicated in the drawing above allows for easy reapplication. In addition, since the clearance between ways is small for CRWG..H series, apply grease or oil directly to raceway for re-greasing.
