Angle rings (L-shaped thrust collars) are used either with NU design cylindrical roller bearings to locate the shaft axially in one direction, or with NJ design bearings to locate the shaft axially in both directions. The rings are made of carbon chromium steel and are hardened and ground. They are supplied as separate components.
