250.15.0300.013 Typ 13/400-KD210 Series 230 280 Type

The double flange slewing bearing is a practical rotational solution designed for machinery where both the inner and outer rings must provide direct flange interfaces for structural attachment. This design incorporates flanges on both rings, offering a straightforward and effective mounting approach for equipment requiring balanced load distribution and simplified assembly.



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

✦ Reduces total assembly height – The flush flange faces lower the vertical profile compared to separate adapter solutions.

✦ Accelerates installation alignment – Integrated pilot diameters on both flanges provide rapid centering without measuring tools.

✦ Improves clearance management – The flange-threaded holes allow through-bolting or blind fastening depending on access.

✦ Minimizes stress concentration – The generous fillet radii at flange junctions reduce notch effects and improve fatigue performance.

✦ Provides direct sensor mounting surfaces – Flange faces are machined with sufficient flatness to accept proximity sensors or encoders.

✦ Allows top-down maintenance – All fasteners are accessible from the upper side, enabling inspection without lifting the load.
