  Urethane Bumpers
 
Urethane Bumpers are available in Ether Polyurethane (shore 90A, 80A) and Ester Polyurethane (shore 70A, 60A, 50A, 40A, 30A, & 20A). The I.D is slightly smaller than the head of the mounting socket head cap screw. The head of the screw will expand the material and prevent the bumper from falling out.

Urethane Bumpers
Urethane Bumpers are availble in either Polyurethane (the harder, shore A90) and ester Polyurethane (medium shore A70 and the soft shore A50). These bumpers are counterbored and have a 1045 cold rolled steel insert that prevents deformation of the part. See the application example at the bottom of the page for mounting and usage reference.
