Aug 20, 2003 DryLin® R linear bearings are composed of self-lubricating polymer iglide® J. With channels that enable flow of dirt and dust, bearings do not need to be sealed. Flat glide pads reduce clearance between liner and shaft, and axial fastener secures bearing tighter to outside housing for added stability. Contact area is increased to 80%, improving overall load capacity. DryLin R bearings are suited for harsh, debris-infested or water-based environments.
