92-200641/1-07232-932 Series 92 type bearing

The internal gear with outer flange slewing bearing is a precision rotational component designed for equipment where the drive arrangement must be integrated within the bearing envelope while maintaining a stable, flange-based connection to the supporting structure. This configuration positions the gear teeth on the inner ring and incorporates a mounting flange on the outer ring, offering a compact and well-protected drive solution for space-sensitive applications.



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

✦ Enhances structural rigidity – The outer flange design provides a continuous, rigid mounting surface that improves overall system stiffness.

✦ Facilitates maintenance access – All bolts are accessible from the outside, eliminating the need for internal disassembly.

✦ Improves gear alignment – The internal gear teeth and outer flange are machined from the same forging, ensuring perfect concentricity.

✦ Enables central pass-through – The open inner ring allows routing of hydraulic lines, electrical cables, or drive shafts.

✦ Simplifies sealing – The flange-mounted outer ring creates a stable sealing surface, reducing leaks in high-pressure environments.

✦ Provides better load distribution – The outer flange spreads loads evenly across the mounting structure, reducing stress concentrations.
