NATR 20 PPXA SKF track roller, with flange rings, with an inner ring

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. 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
