Frequently asked questions
Can it be used on a rotating rod?
Yes. The bushing both slides along the rod and rotates around it, which is what rotating-rod machines need. It is sized for 8 mm rods only, so confirm the rod diameter before installing.
Does it need extra lubrication?
It is described as self-lubricating, which is intended to give long life with low wear and little maintenance. Check your machine's build guide for any lubrication it recommends.
