22 25 28 Series flange bearing

The internal gear with outer flange slewing bearing is a specialized rotational component developed for applications where space constraints, gear protection, and reliable mounting are critical factors. This design places the gear teeth on the inner ring and incorporates a flange on the outer ring, offering a distinctive solution for equipment requiring the drive system to be positioned internally while maintaining a secure interface with the machine structure.



Application Areas:

  • Compact crane turntables and winch drives

  • Aerial work platforms and lifting equipment

  • Solar tracking systems requiring protected gearing

  • Light to medium-duty industrial turntables

  • Packaging and handling machinery

  • Equipment requiring internal drive arrangement and flange mounting

This bearing series comprises an outer ring with an integral flange, an inner ring with internal gear teeth, and a single row of steel balls arranged between precision-ground raceways. The four-point contact ball geometry enables the bearing to simultaneously support axial loads in both directions, radial loads, and tilting moments within a single, compact row of rolling elements.

The outer flange serves as a robust, flat mounting surface that simplifies attachment to the machine structure, reducing the need for complex adaptor plates or additional mounting hardware. The inner ring features internal gear teeth machined directly onto its inner surface, allowing the drive pinion to be positioned within the bearing envelope. This internal gear arrangement keeps the gear teeth protected from external contamination, debris, and mechanical damage, extending service life and improving operational reliability.
