The 608PS radial miniature plastic ball bearing uses stainless steel balls and requires no lubrication. These plastic bearings are corrosion-resistant, lightweight, and offer design flexibility. The rings are made of Delrin Plastic (Polyoxymethylene) while the ball retainer is made of a chemical resistant polymer and the balls themselves are stainless steel 440C. These qualities provide a lube-free operation where other bearings wouldn't hold up.
This special combination of materials provides for anti-rusting, anti-magnetize, and corrosion protection.
