Basic data of standard Series L

Slewing Bearing

Slewing bearing(slewing ring) is a bearing that can bear a large axial load and radial and overturning torque. Slewing bearings are generally accompanied by installing holes, inner gear, outdoor gear, lubricating holes, and sealing devices, which make the mainframe structure compact in design, guide reliable, and easy to maintain. Slewing bearings are combination structures including non-gear, outdoor gear, four-point contact ball slewing bearings, double row ball slewing bearings, cross roller slewing bearings, and three rows roller slewing bearings on. Four-point contact ball slewing bearings have higher static load capacity, while cross roller slewing bearings have higher dynamic load capacity. Applications: Slewing bearings are widely used in construction machinery, concrete machinery, feeding machinery, hoisting machinery, ground processing machinery, light industrial machinery, ship cranes, port equipment, new energy equipment, metallurgical equipment, playground equipment, airport equipment, military equipment, Robots, medical equipment, green facilities, parking equipment, etc.
