applications
Steel industry: Spherical roller bearings are widely used in steelmaking converters, rolling mill gearbox bearing seats, rolling mill rollers and other equipment in the steel industry.
Papermaking machinery: In papermaking machinery, spherical roller bearings are an indispensable component.
Speed reducers: Spherical roller bearings are widely used in speed reducers such as various industrial speed reducers.
Railway vehicle axles: Spherical roller bearings are used on railway vehicle axles, mainly because the axles are subjected to various forces from the vehicle body during the operation of the train, including radial force and axial force.
Crusher: In the crusher, large impact force and vibration are generated during operation, and spherical roller bearings can withstand such heavy loads and impact loads.
Vibrating screen: The vibrating screen will generate continuous vibration during operation, which requires the bearings to withstand the impact force caused by the vibration and maintain a stable working state.
Printing machinery: During the operation of printing machinery, the matching accuracy between the various components is required to be high, but due to the influence of various factors in the mechanical structure and the working process, there may be coaxiality errors between the shaft and the housing. The spherical roller bearing's aligning performance can compensate for this error.
Woodworking machinery: When woodworking machinery is processing wood, factors such as the high-speed rotation of the tool and the irregular force on the wood will cause the machine's bearings to be subjected to complex radial and axial forces.
