Types of slewing bearings

Liebherr is one of the world's leading producers of slewing bearings. Our portfolio comprises many different types, manufactured in a wide range of dimensions and designs.

All of our slewing bearings can be manufactured with internal gears, external gears or without gearing. Special gearing, such as helical and worm gears, are also available upon request. The seal concept is also configured for each individual case of use, and takes account of particular environmental conditions, such as particularly saline or dusty air. The bearings can also be coated for extra corrosion protection.

Tapered roller bearings

Tapered roller bearings can be subjected to radial and axial loads. They are suited to high load conditions. The tapered form of the rolling elements ensures optimum rolling characteristics. The play-free bearing mounting makes the tapered roller bearing particularly suitable for the highest precision and accuracy requirements

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.

Ball bearing slewing rings

Ball bearings are particularly suitable for applications exerting low to medium loads on the bearings. Usually, polymer spacers are installed between the rolling elements, although bearing designs with steel or brass cages are also available.

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.
