China wholesale Double Row Spherical Roller Bearing - Thrust Cylindrical Roller Bearings – Chengfeng Bearing

Product features：

Cylindrical rollers are crowned so that the pressure distribution between the rollers and the raceway surfaces is uniform.
This type of bearing is a separate structure, which can be installed with shaft washer, seat washer, and rolling element components. The axis of the shaft and the housing is not allowed to be inclined during installation. It is used at low speed and can withstand one-way axial load, and cannot limit radial direction displacement. The axial load capacity is large, and the axial rigidity is also strong.

Application

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

Size range:

Inner diameter size range: 30mm~1800mm
Outer diameter size range: 52mm~2080mm
Width size range: 14mm~250mm

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