Four basic requirements for precision preload slewing bearings
  • 2015-06-17 10:58:00

1. Adjust the axial clearance and radial clearance of the bearing to negative clearance, zero clearance, and narrow clearance, such as (0.03-0.05).2. Bearing end runout and radial runout: Bearing end runout with a diameter less than 1m is 0.05 and radial runout is 0.08; bearing end runout with a diameter greater than 2m is 0.08 and radial runout is 0.15...

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...

Applications of external internal slewing bearing
  • 2014-11-14 09:18:00

Internal gear slewing bearings are widely used in many medium to heavy load applications where there are design limitations and restrictions against using an external pinion, or when the outer ring surface needs to be protected for contamination and safety purposes. Standard I-series slew rings are composed of an Internal ring with straight gear teeth, ...
