As a leading manufacturer of specialized slewing bearings, we offer our premium Three-Row Roller Slewing Bearings, designed for the most demanding heavy-duty applications. This bearing type features three independent raceways—two axial and one radial—each equipped with cylindrical rollers. This unique, segregated design allows each row to be optimally dimensioned to handle specific load directions.

The separated raceways enable the bearing to simultaneously support heavy axial loads (in both directions), substantial radial forces, and high tilting moments with minimal clearance and maximum rigidity. Compared to single-row or double-row bearings, the three-row roller design offers a significantly higher load capacity and a longer service life under extreme operating conditions.

Engineered for durability and precision, these bearings are manufactured using high-quality induction-hardened rings and precision-matched rollers to ensure smooth rotation and consistent performance. They are the ideal solution for extra-heavy machinery such as large excavators, tunnel boring machines (TBMs), heavy-duty cranes, wind turbine generators, and offshore equipment. Our three-row roller slewing bearings provide the reliability and robust performance required to keep your critical operations running efficiently.
