FUN Ball bearing

The double flange slewing bearing is a well-balanced rotational component engineered for applications that demand straightforward mounting on both the inner and outer rings. Featuring flanges on both rings, this design provides a practical, symmetrical solution for equipment where installation efficiency and structural stability are key priorities.



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

This bearing series comprises an inner ring with an integral flange, an outer ring with an integral flange, and a single row of steel balls arranged between precision-ground raceways. The four-point contact ball geometry enables the bearing to support axial loads in both directions, radial loads, and tilting moments simultaneously within a single, compact row of rolling elements.

Both the inner and outer rings are equipped with broad, flat flanges that function as direct mounting interfaces. These flanges allow for straightforward bolted attachment to the machine structure, eliminating the need for adaptor plates or complex mounting hardware. The dual-flange design promotes accurate alignment during installation and ensures even distribution of loads across both rings.
