232.20.0500.503 Typ 21/650.2-KD210 series 232.20 282.30 Type

The internal gear with outer flange slewing bearing is a robust rotational component designed for applications where the drive system must be integrated within a compact space while providing a reliable, flange-mounted interface to the equipment structure. This configuration offers inherent advantages for machinery operating in challenging environments where gear protection and installation convenience are primary concerns.



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

✦ Strengthens system stiffness – The outer flange offers a broad clamping surface, improving overall structural rigidity.

✦ Allows easy bolt access – All mounting bolts are positioned externally, enabling quick inspection and re-torquing without disassembly.

✦ Ensures concentric gear meshing – The internal gear and flange are machined in a single clamping operation, guaranteeing consistent gear alignment.

✦ Permits media feed-through – The hollow inner ring accommodates cables, lubrication lines, or pneumatic tubes through the center.

✦ Minimizes leak paths – The rigid flange mount provides a stable seal compression surface, reducing the risk of lubricant leakage.

✦ Distributes loads evenly – The flange’s large contact area reduces point loading on the supporting structure, preventing localized stress.
