roll stand. Bearings of various types are used as axial bearings. The bearings used for high axial forces and moderate speeds are axial tapered roller bearings (Figure 6), double row tapered roller bearings with a large contact angle (Figure 7) or axial spherical roller bearings (Figure 8). The axial tapered roller bearing has a ring

NSK KV type, four roll tapered roller bearings and in some mills, NSK KH type, two roll tapered roller bearings are used. Special heavy duty roller retainer designs are used because of the high axial forces and misalignment. Low radial internal clearance insures that there is even load distribution across the bearing.
