Four-point contact ball slewing bearing is a different type of bearing. It can also be said that it is an angular contact ball bearing that can handle the biaxial axial load. Four-point contact ball slewing bearing mainly consists of an inner ring, an outer ring, a row of steel balls, and a cage (or spacer). The inner and outer ring raceways are peach-shaped cross-sections. When there is no load or pure radial load, the steel ball and the ferrule appear as four-point contact, which is the origin of this name.

Features of Four-point Contact Ball Slewing Bearing

• Four-point contact ball slewing bearing requires a minimum amount of space and can carry either pure axial or combined loading.
• Four-point contact ball slewing bearing can be separated, i.e., the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves. The split inner circle leads to easier mounting and dismounting of the bearing.
• Many balls are incorporated, giving the bearing its high load-carrying capacity.

Application of Four-point Contact Ball Slewing Bearing

• Aerial platform vehicles

Aerial work platform vehicles typically employ such a slewing ring and are compact. This type of slewing bearing is also subjected to axial force, radial force and tilting moment, and is widely used in small and medium-sized construction machinery.

• Truck crane

Truck cranes are usually using large single-row four-point contact ball slewing bearings. This slewing bearing can bear more enormous axial, radial, and tilting, enabling the crane to lift heavy loads stably and reliably.

• খননকারী

Excavator is usually using internally quenched gear single-row four-point contact ball slewing bearing. This slewing bearing can bear axial load, radial load, and tilting moment and can withstand significant impacts. Rotation is flexible and stable.
