RD800 Standard bearings

The 162 series represents a distinguished class of single-row crossed roller slewing bearings with internal gearing, developed to meet the rigorous demands of heavy-duty rotary applications where precision, durability, and structural integrity are non-negotiable. This series is characterized by its generous roller complement, optimized raceway geometry, and robust internal gear design, making it a preferred choice for equipment operating under sustained high loads and challenging environmental conditions.

The 162 series utilizes the proven single-row crossed roller principle, with cylindrical rollers arranged in an alternating perpendicular pattern within a single raceway. This configuration enables the bearing to manage complex load scenarios—combining radial forces, axial thrust in either direction, and substantial overturning moments—within a unitary assembly. Unlike double-row designs that require additional axial space, the 162 series achieves comparable load capacity in a more compact form factor, offering engineers greater flexibility in system layout.

A defining feature of this series is the internal gear, which is forged integrally with the inner ring rather than being a separately attached component. This monolithic construction enhances gear tooth root strength, improves concentricity between the raceway and pitch circle, and eliminates potential misalignment issues associated with bolted or welded gear rings.
