Crossed roller slewing ring bearing
1. Introduction of LYHY crossed roller slewing bearings
LYHY is a professional manufacturer in slewing ring bearings since 1993. We can also design and make other standard and non-standard ball bearings, roller bearings and precision bearings as per customer's different technical requirements.
Slewing bearing is also called slewing ring, slewing ring bearing, turntable bearing, and rotary bearing.
With the cross roller Ring, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90° groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including, radial, axial and moment loads. Since the Cross-Roller Ring achieves high rigidity despite the minimum possible dimensions of the inner and outer rings, it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines.
2. Structure:
Cross roller slewing bearing has three different types:
Cross roller ball slewing bearing with no gear
Cross roller ball slewing bearing with external gear
Cross roller ball slewing bearing with internal gear
3. Features
Cross roller slewing ring bearings have following features:
1. High precision: cross roller bearings can be made high precision bearings, at P4, P2.
2. High rigidity: These series roller bearings are with preload.
3. High load capacity: This series roller bearing can support axial load, radial load, and tilting load.
4. Small volume: this series roller bearing can save space for the machine.
4. Application
Cross roller slewing rings are widely applied in the precision rotary table, rotary joint of manipulator, medical equipment, and measuring instrument etc

1. Introduction of LYHY slewing ring bearings
LYHY is a professional manufacturer in slewing ring bearings since 1993. We can also design and make other standard and non-standard ball slewing ring bearings, roller slewing bearings and precision slewing ring bearings as per customer's different technical requirements.
Slewing ring bearing is also called slewing ring, slewing bearing, turntable bearing, and rotary bearing.
Slewing ring bearing is a bearing that able to bear axial load, radial load and overturning torque. Under normal circumstances, slewing ring bearings have their own mounting holes, lubricant holes and seal holes, to meet the different needs of the various host working under the various conditions;
On the other hand, slewing ring bearing itself has characteristics of compact structure, guide rotating convenient, easy to install and maintaining easily.
2. Structure
2.1 Slewing ring bearings have different types as per different structures, here below is what we offering now:
Single row ball slewing ring bearings
Double row ball slewing ring bearings
Crossed roller slewing ring bearings
Triple row roller slewing ring bearings
Flange slewing ring bearings
2.2 The above slewing ring bearings can also be divided into three different types as per different transmissions:
Slewing ring bearings with no gear
Slewing ring bearings with external gear
Slewing ring bearings with internal gear
3. Features:
Slewing ring bearings have more features: compact structure, reliable guide, simple installation, and easily maintenance
4. Application:
Slewing ring bearings can be widely used in lifting & transport machinery, mining machinery, construction machinery, port hoisting machinery, port oil transfer equipment, onshore and offshore crane, excavator, concrete machine, paper machine, plastic and rubber machine, weave machine, steel plant, electronic power plant, wind power generator, other construction and industry machines or equipments and other large rotary device.
If you have any requirement of slewing bearings, please be free to contact us.
