Roller bearing slewing rings

Liebherr roller bearings are suitable for medium to high loads. They are designed as standard in triple-row configurations with two axial and one radial roller raceway. Depending on the case of use, other designs and variants are however also available.

Standard series

In addition to customised projects, our portfolio contains a comprehensive standard programme of one-piece Liebherr roller bearing slewing rings.

Roller bearings from the standard programme
External diameter 800 - 7,500 mm
Rolling element diameter 12 - 140 mm
Gearing with external gears / with internal gears / without gearing
special gearing upon request
Gear module 8 - 50 mm

Types of roller bearing slewing rings

  • Triple-row roller bearings
    In heavy machines, such as mining excavators, roller bearing slewing rings tend to be used mainly on account of the high loads.

  • Triple-row roller bearings for tunnel boring machines
    Roller bearing slewing rings for tunnel boring machines are fitted with a preloaded retaining raceway. The cup springs for preloading the raceway ensure that the rolling elements never lose contact with the raceway, thereby guaranteeing optimised wear characteristics.

  • Triple-row roller bearings with special seals
    Triple-row roller bearing slewing rings can be fitted according to need with specially-developed seal systems. These can protect the bearing in thrusters, for example, against the penetration of seawater while at the same time preventing the leakage of lubricants.

  • Cross roller bearings
    On account of their play-free mounting, cross roller bearings offer greater precision than traditional roller bearings. They are used above all in tunnel boring machines and in conveyor technology.

  • Roller bearings with bolt connection
    Bearing designs with bolt connections are used when in the presence of a special adjacent construction. This is often the case with cranes.
