Features of double-row ball slewing bearing
  • 2015-08-05 06:53:00

The double row ball slewing bearing has three races. Steel balls and spacer blocks can be directly discharged into the upper and lower raceways. Arrange two rows of steel balls with different diameters according to the force. This open assembly is very convenient. The upper and lower arc raceway bearing angles are both 90°, which can bear large axial fo...

Four-point contact ball slewing bearing
  • 2015-04-22 06:02:00

The four-point contact ball slewing bearing is composed of two races, which is compact and light in weight. The steel ball is in contact with the raceway of the ring at four points, which can bear axial force, radial force and overturning moment at the same time. It can be used for construction machinery such as slewing conveyors, welding operators, sma...

Crossed roller slewing bearing
  • 2015-02-11 09:08:00

The crossed roller slewing ring can bear axial load, overturning moment and radial load at the same time. The structure and application of the crossed roller slewing bearing is basically the same as that of the four-point contact ball slewing bearing, except that the rolling elements change from steel balls to rollers, and the contact between the rollin...

Applications of external gear slewing bearing
  • 2015-01-11 11:13:00

External geared slewing bearings are widely used in many medium to heavy load applications. This includes industrial, man lift, cranes, robots and welding positioners. Standard E-series slew rings are composed of an external ring with straight gear teeth, an internal ring, and a specific number of rolling elements in between. These can be driven through...
