The double flange slewing bearing is a highly adaptable rotational component developed for applications where both the inner and outer rings require direct flange mounting to their respective structures. This symmetric design features flanges on both rings, offering a practical and efficient solution for equipment where installation simplicity, structural stability, and even load distribution are essential.



Application Areas:

  • Compact crane turntables and winch drives

  • Aerial work platforms and lifting equipment

  • Solar tracking systems with space constraints

  • Light to medium-duty industrial turntables

  • Packaging and handling machinery

  • Equipment requiring flange mounting on both rings



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

  • Dual flange mounting: Both rings feature integral flanges for versatile installation

  • Symmetric design: Simplifies alignment and ensures even load distribution

  • Space efficiency: Single-row design saves axial and radial space

  • Enhanced rigidity: Flanges provide direct, stable load transmission

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


Features

✦ Streamlines machine integration – The dual-flange design allows the bearing to serve as a structural connection point, reducing the need for separate support brackets.

✦ Improves clamping rigidity – The evenly spaced bolt holes on both flanges ensure uniform preload distribution across the entire ring circumference.

✦ Reduces design lead time – The flange geometry is pre-engineered to accept standard bolts, eliminating the need for custom fastener specification.

✦ Supports edge-to-edge mounting – The flush outer flange profiles enable the bearing to be installed edge-to-edge with adjacent components, saving space.

✦ Allows field exchange without rework – The mounting holes are positioned identically on both flanges, enabling end-for-end swapping without additional drilling.

✦ Enhances thermal stability – The symmetric flange mass balances thermal expansion forces, reducing distortion during temperature changes.
