Double-row Ball Slewing Bearing with Different Ball Diameters

In order to cope with the different combinations of axial force, overturning moment and radial force generated under various working conditions, the contact angle of the double-row different diameter ball slewing bearing can be adjusted accordingly

Double-row Ball Slewing Bearing with Different Ball Diameters

Double-row Ball Slewing Bearing with Same Ball Diameters

The balls of upper row mainly bear the axial load and overturning moment, so the diameter of the ball is larger than that of the lower row.

Double-row Ball Slewing Bearing with Same Ball Diameters

The balls of upper row mainly bear the axial load and overturning moment, so the diameter of the ball is larger than that of the lower row.

Four-point Contact Ball Slewing Bearing

The single-row four-point contact ball slewing bearing has a compact structure and light weight, four point contact between steel ball and arc raceway. The four-point contact ball slewing bearings are used in construction machinery such as rotary conveyors, small and medium cranes and excavators.

Four-point Contact Ball Slewing Bearing

Four-Point Contact Slewing Bearing with Flange

The four-point contact ball slewing bearing with flange can bear directional, radial and moment loads, it has a cage (or spacer block), the full-complement ball structure is only used when the load is large.

Four-Point Contact Slewing Bearing with Flange

Three-row Cylindrical Roller Combined Slewing Bearing

The axial load and radial load of the structure are borne by different rollers respectively. The axial load and overturning moment are borne by the two groups of rollers placed horizontally on the axis, and the radial load is borne by the group of rollers placed vertically on the axis.
