Cooper Split Roller Bearings

Supplier: CBC Australia

The Plummer Block replacement that saves time and money

Price Guide: POA

Cooper Split Roller Bearings are the ideal solution for trapped applications and limited access locations. Cooper bearings have cylindrical rollers with modified line contact and have their main components made in halves.

Simple assembly of these halves around the shaft eliminates axial threading, special machining, threaded portions and locknuts involved with solid bearings; and enables shafting to be designed solely to strength requirements.

The bearing races and rollers are made from first quality carbon chrome steel, through hardened and precision finished. Races have angled joints to ensure continuity of contact with the rollers. Cage halves are made from light alloy or bronze, joined by spring steel clips.


  • Easily fitted to recessed shafts, crankpins and other applications where the installation of a solid bearing would be impractical or impossible.
  • The Cooper bearing is completely split to the shaft making installation and inspection simple, minimising downtime and reducing maintenance hours.
  • Ancillary equipment does not need to be removed to check a Cooper bearing.
  • The entire bearing can be inspected by simply removing the pedestal cap and the top part of the cartridge housing and outer race assembly.
