Definition of slewing bearing

Slewing bearing also called slewing ring bearing is a new type of mechanical component. It consists of inner and outer rings and rolling elements. The slewing bearing is a large bearing that can withstand comprehensive loads. It can withstand large axial and radial loads and overturning moments at the same time.

Material: C45, 50Mn (carbon structural steel), 42CrMo (alloy structural steel). Usually, 50Mn and 42CrMo are used.

Roller: it is made of GCr15 or GCr15SiMn steel.

Sealing: The material of the sealing ring is generally made of oil-resistant nitrile rubber (NRB). For special requirements, hydrogenated nitrile rubber (HNRB) and fluorine rubber (FKM) can be selected.

Application of slewing bearing

It has a compact structure and is easy to use, easy to install, and maintain. It has been widely used in marine equipment, engineering machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery, and other industries.

The shape types of most slewing bearings are as follows:

1.External tooth  2.Internal tooth  3.Toothless  4.Flange type

DK-Bearing provides standard and custom slewing bearings.
