Bearing Characteristics
Strong Bearing Capacity
Mainly bears radial and axial combined loads dominated by radial loads, and generally does not bear axial loads alone.
Separable Installation
The inner and outer rings can be installed separately, and the axial clearance and radial clearance can be adjusted during the installation process, or pre-interference installation can be performed.
Axial Displacement Limit
It can limit the axial displacement of the shaft or the housing, and does not allow the shaft to be tilted relative to the housing or the hole.
Clearance Affects Life
The size of the axial clearance of the tapered roller bearing directly affects the service life of the bearing.
Application Areas
Machine Tool Industry
Used in the spindle, feed shaft and other parts of the machine tool, bearing cutting force and rotation load, ensuring the accuracy and stability of the machine tool.
Automotive Industry
Applied to the wheel hub, differential, transmission and other parts of the car, supporting the rotation of the wheel, transmitting power and torque.
Reducer Industry
Supporting the gear shaft in the reducer, bearing the radial and axial forces generated during gear transmission, and ensuring the normal operation of the reducer.
Mining Machinery
In equipment such as crushers and ball mills, tapered roller bearings are used to support rotating parts and bear huge impact loads and radial loads.
Metallurgical Industry
In various equipment of rolling mills and steel mills, it is used to withstand rolling force and axial force to ensure stable operation of the equipment.
