Unique production processes

Slewing bearings

Step by step from ring to slewing bearing: production processes that have it all​

Whether harsh environmental conditions, extreme installation situations, heavy loads or high radial and axial forces – slewing bearings must withstand the various environmental conditions, permanently and reliably. Unique production processes ensure that Liebherr slewing bearings are robust and durable in any installation situation.

Large slewing bearings, high vertical integration

Particularly in quality-determining production steps, Liebherr scores with a high level of vertical integration. This ranges from the machining and slip-free induction hardening of bearing raceways, through the gear cutting of slewing bearings, to surface coating in house. Professional know-how and modern machinery characterize the entire manufacturing process.
