China OEM Vertical Mill Bearing Nu21/500mx3/Hcc9 - Hot Sell Thrust Roller Bearing Price – Chengfeng Bearing

Product features：

Thrust spherical roller bearing load is transmitted from one raceway to another raceway at a certain angle to the bearing axis. In addition to bearing radial load, it can also bear axial load acting at the same time. It has self-aligning ability and can allow certain shaft deflection and centering error between the shaft and the bearing seat.

Application

This type of bearing is mainly used in hydraulic generators, vertical motors, propeller shafts for ships, tower cranes, extruders, vertical crushers, etc.

Size range:

Inner diameter size range: 60mm~1620mm
Outer diameter size range: 130mm~1860mm
Width size range: 39mm~426mm

Tolerance: P0, P6, P5, P4 precision grades are available.
