EDT Corp.'s Poly-Round plane bearing insert has a stainless pin on the outer diameter to facilitate drop-in installation into bearing housings without utilizing a set-screw as an anti-rotation device. Poly-Round bearings are self-aligning bearing inserts manufactured from a variety of polymer materials so they are suitable for various operating conditions. The "Plus" pin of Poly-Round Plus bearings eliminates the necessity of drilling and tapping a hole through a housing to assure the bearing insert can align but not rotate.
