Does the Roller Follower have lubricant such as grease sealed in before shipment?
Types NAST and RNAST do not have grease sealed in; before use, remember to seal in grease. (Note that for all standard items, the rollers, cages, and inner rings are temporarily assembled with a small amount of grease used and incorporated into the outer ring. (If completely degreased products are needed, contact us.) In a normal use environment, high quality lithium based grease is recommended.
