Combined roller and ball bearing slewing rings

Combined roller and ball bearings are designed as standard with a roller raceway (supporting raceway) and a ball raceway (retaining raceway). This makes this type of design particularly suitable for high axial loads and harsh environmental conditions.

Standard series

In addition to customised projects, our portfolio contains a comprehensive standard programme of one-piece Liebherr combined roller and ball bearings.

External diameter 800 - 7,500 mm
Rolling element diameter 16 - 100 mm
Gearing with external gears / with internal gears / without gearing
special gearing upon request
Gear module 8 - 50 mm
Technical information
  • Combined roller and ball bearing slewing rings
    The combination of roller and ball bearing offers a cost-effective alternative to traditional roller bearing slewing rings. This bearing type is mainly designed for axial loads, and is frequently used in conveyor technology, for example with bucket excavators.
