Triple Row Roller Slewing Bearing

Triple Row Roller Slewing Bearing

Provide highest load in small spaces for large machinery

Three Row Roller.png

Triple-row roller bearings are made up of three separate rows of rollers - two primarily for axial load, and one for radial (all three take moment loads). The rollers are positioned so the bearing can handle the highest capacity possible while keeping overall diameters small with high precision and rigidity.


Like double-row ball bearings and cross-rollers, these triple-row roller bearings can handle extremely high loads, with the three-row roller, size for size, able to handle the most. These are often found in tunnel boring machines, wind turbines, stackers and reclaimers, and harbor cranes.

  • For heavy load applications

  • High tilting moment load capacity

  • High precision and High rigidity

  • Long service life

  • The mounting surface must conform to defined standards for flatness and strength.

  • Provide the highest axial load possible and can accommodate very high tilting moments load

  • Available in gearless, internally geared and externally gear versions

  • This type of bearing is usually with induction hardened gear teeth.

  • Typical sizes usually >1000mm, available up to 2000mm

  • Available with different corrosion protection coatings

  • Mating pinions are available for all slewing bearings.
