Slewing ring is linked by 2 structure, inner ring and outer ring. Two rings rotate separately and transmit load. A connector simple equipped in slewing ring and can be linked with other structures fast and convenient. What’s more, 2 rings rotate become more smoothly.
Slewing ring can be withstood single or multiple loading. There are loading, radial loading, axis loading, tilting moment and output torque.
Construction of a slewing ring:
1, Internal ring
2, External ring
Slewing Ring consist of an internal and external ring with an integrated raceway system and optional internal or external teeth. The normal material is 50Mn.
In Slewing Rings, better rotation and loading transmission are achieved by special design and precision production of the rolling elements.
Spacers separate the rolling elements and minimize friction and wear.
5, Mounting Holes
The force is transmitted to the mounting structure by bolts. Through holes or threaded holes can be provided in the inner and outer rings for these bolts.
Polymer seals protect the Slewing Rings from normal dirt penetration, dust and loss of lubricant.
7, Plug hole
The rolling elements are inserted during manufacture through the filling plug hole, retained by the filling plug which is then secured by a pin.
Slewing Rings are designed with optional internal or external gear.
9, Grease nipple
Slewing Rings are designed for grease lubrication which is carried out via grease nipples.
Bearing type and serial No.
●Mostly, a combination of axial, radial and tilting moment loads occur.
●Radial loading cannot exceed 10% of axis loading.
●Operating temperature on Slewing Ring in range from -20°C to +60°C
●Fasten the bolts alternately
●Check bolts and ensure proper retightening load
