EDT Corp’s Poly-Round Plus is a version of the company’s Poly-Round plane bearing insert. It has a stainless pin on the outer diameter to facilitate drop-in installation into bearing housings without using a set-screw as an anti-rotation device. Poly-Round bearings are self-aligning bearing inserts made from a variety of polymer materials that are suitable for multiple operating conditions. Plus’ pin eliminates the necessity for drilling and tapping a hole through a housing to ensure the bearing insert is aligned but does not rotate.
