R3 series

Triple-row roller slewing bearings

Slewing bearings in our R3 series have the highest static and dynamic load capacity thanks to their three roller raceways (one supporting, one retaining and one radial raceway).

They are used for maximum loading in small spaces, guaranteeing a high stiffness and a uniform rotational resistance.

Typical applications of triple-row roller slewing bearings include offshore technology, transshipment technology, tunnel boring machines, stackers and harbour cranes.

While models without gear (R30) are not very common, most bearings in this series fall into one of the following groups:
