Track rollers are designed to run on all types of tracks and to be used in cam drives, conveyor systems, etc. The outer ring running surface is crowned as standard. They are available in many different types and designs and for a wide variety of operating conditions and applications. The thick-walled outer ring enables high radial loads, while reducing distortion and bending stresses. The crowned outer ring running surface is beneficial for applications where outer ring tilting relative to the track may occur or where edge stresses need to be minimized
