Ball bearing bearing unit CBx

polyurethanechloropreneabrasion-resistant

Product Overview
Covered bearings in the CBx series consist of a precision sealed ball bearing with a urethane or neoprene cover cast directly to the bearing. These units deliver smooth, quiet, non-marring operation for industrial conveying, guide and wheel applications. Urethane versions offer high abrasion resistance and extended service life; neoprene versions offer flame and weather resistance. Available durometers: 35, 60, 80, 85 and 95 Shore A.

Product Types

• CBx — Single bearing, urethane or neoprene cover
• CBD — Double bearing, neoprene cover
