SD.650.20.00.C-SD.20.C SD.32.C Bearing

The double flange slewing bearing is a robust rotational component designed for equipment where both the inner and outer rings require direct flange mounting for structural integration. Featuring flanges on both rings, this design provides a balanced and practical mounting solution that simplifies assembly while ensuring reliable load transmission.



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

✦ Minimizes bending stress at mounting interface – The dual-flange construction distributes clamping forces evenly, reducing stress concentration at bolt holes.

✦ Allows installation from either side – Identical flange faces permit the bearing to be mounted with either ring facing the load.

✦ Simplifies retrofit upgrades – The flange bolt pattern matches common industry standards, allowing direct replacement of older designs.

✦ Provides defined compression control – The flange thickness ensures consistent seal compression, reducing the need for adjustment shims.

✦ Ensures coaxiality – The pilot diameter on the flange face ensures quick coaxial alignment with mating components.

✦ Enables hybrid mounting – One flange can be bolted rigidly while the other uses clearance holes for thermal expansion compensation.
