NBL.20.0944.200-1PPN-NBL Series untoothed bearing

The double flange slewing bearing is a thoughtfully engineered rotational component designed for applications where both mounting interfaces require flange-based attachment to their respective structures. This configuration incorporates flanges on both the inner and outer rings, providing a symmetric and stable mounting solution that simplifies equipment 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



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 overall machine envelope – The integral inner and outer flanges eliminate the need for separate mounting plates, allowing tighter packaging.

✦ Shortens assembly time – The flanges provide ready-to-bolt surfaces on both rings, reducing alignment and fixturing steps.

✦ Enhances torque transmission – The dual-flange interface ensures that drive forces are transferred directly to the machine frame without intermediate adapters.

✦ Provides design symmetry – Both flanges are machined to identical reference datums, enabling interchangeable mounting configurations.

✦ Prevents seal lip distortion – The parallel flange faces maintain consistent seal groove geometry, reducing lubricant leakage.

✦ Allows blind mounting – The open flange design enables visual alignment, even in tight machine compartments.
