Better quality, Better price, Better service.
Our factory is a professional manufacturer in slewing ring bearings.
Slewing bearings (slewing rings), is a bearing that able to bear axial load, radial load and overturning torque. Slewing bearing are generally accompanied with installing holes, inner gear, outside gear, lubricating hole and sealing devices, which enable mainframe structural compact in design, guide reliable, and easy to maintain.
Slewing bearings include non-gear, external gear, and internal gear with different type, and has single-row ball slewing bearings, double-row ball slewing bearings, cross- roller slewing bearings and three-row roller slewing bearings with different structure. In which, single-row ball bearings have higher static load capacity; While cross- roller bearings have higher dynamic load capacity.
Slewing bearing widely used in lifting machinery, excavate machinery, construction machinery, port machinery, ship machinery, as well as precision radar, missile launchers and large rotary device such as missile launcher.
2. Structure:
Single row ball slewing bearing has three different types:
Single row ball slewing bearing with no gear
Single row ball slewing bearing with external gear
Single row ball slewing bearing with internal gear
3. Features
Single row ball slewing ring bearings have following features:
Compact in structure and light in weight.
4. Application:
Single row ball slewing ring bearings are widely used in slewing conveyers, welding arm and positioned, medium duty cranes, excavators and other engineering machines
