Crossed roller slewing ring bearing
1.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
Triple row roller slewing ring bearing 
1.Slewing bearing is also called slewing ring, slewing ring bearing, turntable bearing, and rotary bearing. 
Three row roller slewing ring bearing has three seat-rings, which separate the upper, lower and radial raceway, via which the load of each row of the rollers may be specified. Thus it can carry different load simultaneously and its load capacity is the largest one of the four types
 
2. Structure:
Triple row roller slewing bearing has three different types:
Triple row roller slewing bearing with no gear

The suitable temperature and working environment for slewing bearing
The slewing bearing produced by our company can work normally at -300C.~+ 700C. If users need to adapt to lower or higher temperature support, our engineering technicians can design for you. If the slewing bearing are used in particularly hostile environment, such as Marine c1imate, dust or abrasive particles (dust, cement, coal powder) etc. Special sealing rings, protective devices, and proper oil paths must be selected. Therefore, we hope users to do the daily maintenance work to make your slewing bearing function normally

Installation  of slewing bearing
1.Handling and transportation .The slewing bearing must be handled carefully

.Transportation and storage of slewing bearing should be held horizontally and stored in a dry room

.For hoisting lift bolt is suitable and please move it horizontally , do not hit anything, especially the direction collision

.The slewing bearing surface is covered with antitrust agent, whose rust proof life is usually six months For those whose storage

  life of more than six months (such as accessories) should take the antitrust package or other storage measures again

2.Installing support requirements .Generally, install matching support adopts tubular structure , the cylinder's wall should be better

   aligned at the center of the raceway
