Track Runner Bearings
Track runner bearings are designed to run in tracks and cam drives. The outer ring on these bearings are thick-walled to accommodate shock loads and bending stress.
Standard designs have a crowned outer surface which allows for some angular misalignment between the bearing and track. With the exclusion of single row cam rollers these bearings are also available with a cylindrical outer ring.
The 3 main variants are:
- Cam Followers - internal design based on needle or cylindrical roller bearings, with threaded stud
- Support Rollers - internal design based on needle or cylindrical roller bearings
- Cam Rollers - internal design based on ball bearings
