High definition Bearing 30211 - Thrust Tapered Roller Bearings – Chengfeng Bearing
High definition Bearing 30211 - Thrust Tapered Roller Bearings – Chengfeng Bearing Detail:
Product features：
Thrust tapered roller bearings are equipped with truncated truncated rollers (the big end is spherical), and the rollers are accurately guided by the rib of the raceway ring (shaft washer, seat ring). The design is such that the vertices of the conical surfaces of the shaft washer and the raceway surface, the raceway surface and the roller rolling surface intersect at a point on the bearing centerline.
One-way bearings can withstand one-way axial loads.
Bidirectional bearings can withstand bidirectional axial loads.
The two-way bearing adopts clearance fit, and the shaft sleeve must be used to locate the middle ring axially.
Thrust tapered roller bearing with outer cover can carry larger axial force and lower speed.
Application
This type of bearing is mainly used in crane hook, oil drilling rig swivel, rolling mill roll diameter, etc.
Size range:
Inner diameter size range: 38mm~670mm
Outer diameter size range: 66mm~900mm
Width size range: 18mm~319mm
Tolerance: P0, P6, P5, P4 precision grades are available.
cage
The cage generally adopts brass solid frame and stamping frame.
Supplementary code:
