tony27 Posted January 29, 2014 Report Share Posted January 29, 2014 Needle rollers have no place in linkages from a engineering viewpoint as the amount they rotate is minimal & they're designed to be constantly rotating, ideal is to make aluminium bronze(work hardens) or more commonly phosphor bronze(has self lubricating qualities) bushings of the same dimensions Doesn't mean I don't still have needles in my bike but I only because I've never gotten around to making up any at work Quote Link to comment Share on other sites More sharing options...

Solid bushes would be cheaper and easier to replace.. TLTEL Quote Link to comment Share on other sites More sharing options...
