Four-point Contact Rolling Element Ball Slewing Ring Turntable.Small Diameter Four-point Contact Ball Geared Slewing Ring Turntable with Deformable Ringsgear slewing bearing consists of two rings (one inner ring and one outer ring.) It has compact structure and light weight.

Since the light slewing bearing is so critical, careful maintenance is necessary. More than 96% of slewing ring bearing failures are due to surface-originated lubrication problems, contamination, overloading, and improper installation and mounting fits. These surface failures occur much earlier than classical fatigue failures and are less predictable.

Slewing bearing application for crane - Rack and pinion crane. Small Diameter Four-point Contact Ball Geared Slewing Ring Turntable with Deformable Rings. A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy things and transporting them to other places. The part that plays an important role is the slewing bearing. The large diameter slewing bearing is a critical part of lifting equipment, simultaneously handling all combinations of thrust, radial, and tilting moment loading.

As its balls are four point contacted with the raceway, the slewing bearing can take axial load, radial road, and tilting moment at the same time. Small Diameter Four-point Contact Ball Geared Slewing Ring Turntable with Deformable Rings has the same structure with the ordinary slewing,but the weight is light,and rotate flexibly,which widly used engineering machinery, construction machinery, metallurgy mining machinery, shipping port machinery, environmental machinery, light industrial machinery, petrochemical machinery, engineering vehicles, military devices, food machinery, canning nachinery, car parking systems etc.


The face contact roller-slide combined working method is mainly used for rotary turntable bearings, and now the new rotary bearings are compact and highly accurate, so it is most suitable to use the face contact roller-slide combined working method.
