22054101-22 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



High load-carrying capacity
Resistance to high and low temperatures
Noise-free operation
Strictly controlled tolerances and appropriate internal clearance
Long service life and low maintenance requirements
Prevention of unexpected downtime (avoiding bearing fracture, seizure, and safety incidents caused by such failures, with anti-tilting capability)

Characteristics

  • Combined load capability: Handles axial, radial, and tilting moment loads simultaneously

  • Integrated outer flange: Simplifies mounting and reduces component count

  • Protected gearing: Internal gear teeth are shielded from external contamination and damage

  • Space-saving design: Allows the drive pinion to be positioned within the bearing envelope

  • Rigid connection: Flange provides direct, stable load transmission

  • Smooth rotation: Optimized raceway geometry ensures consistent, reliable motion


Features

✦ Simplifies maintenance access – The outer flange design allows inspection and bolt tightening without entering the machine interior.

✦ Reduces backlash in gear meshing – The internal gear geometry with precision-ground teeth minimizes play, improving positioning accuracy.

✦ Enables through-shaft integration – The open inner ring bore accommodates drive shafts, rotary unions, or sensor wiring.

✦ Lowers noise emission – The enclosed internal gear cavity dampens meshing noise, creating a quieter working environment.

✦ Improves gear protection – The internal gear location shields teeth from falling debris and accidental tool strikes.

✦ Allows compact drive arrangement – The pinion can be positioned coaxially within the ring, reducing overall machine width.
