Most common materials are C45 and 42CroMo4N.

A Torriani slewing ring bearing can be designed as a ball bearing or cross roller bearing. In addition, they are very strong in producing double row bearings and customer-specific bearings. The pictures above show the different types of bearings. The advantage of a double row slewing ring bearing is that a higher load is possible within the same diameter as a single row bearing.

Besides slewing ring bearings Torriani also supplies worm gear slewing rings.

Benefits of worm gear slewing rings:

-          Shielded in a housing

-          The worm gear slewing ring is self-locking

-          Suitable for direct mounting of a hydraulic motor

-          Fast installation
