Product Description

ZYS Spherical Roller Bearing 21307 with high precision



Zys Spherical Roller Bearing 21307 with High Precision


Application of ZYS spherical roller bearings:

Continuous Casting Machines

Mechanical Fans and Blowers

Gearbox and Pumps 

Wind Turbines

Material Handling 

Marine Propulsion and Offshore Drilling

Mining and Construction Equipment

Pulp and Paper Processing Equipment


Spherical roller bearings have two rows of rollers that are mainly used for withstanding radial loads and also axial loads in either direction. Self-aligning roller bearings have high radial load capacity, especially suitable for heavy load or vibration load, but can not withstand the axial load. Spherical roller thrust bearings have good self-aligning properties and can compensate for the coaxiality error.
