NUKRE80

20133281436308318377NUKRE80 Stud Type Track Rollers are designed to run on all types of tracks and to be used in cam drives, conveyor systems, etc. These bearings have a thick-walled outer ring, which enables them to accommodate high radial loads, while reducing distortion and bending stresses.

The outer ring running surface is crowned as standard. This is beneficial for applications where angular misalignment relative to the track may occur or where edge stresses need to be minimized. With the exception of single row cam rollers, NUKRE90 Stud Type Track Rollers are also available with a cylindrical (flat) outer ring running surface.
