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

This bearing series consists of 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 rings are manufactured with wide, flat flanges that serve as mounting interfaces, allowing direct bolted attachment to the respective machine structures without requiring adaptor plates or additional mounting brackets. This dual-flange design facilitates accurate alignment during installation and ensures even load distribution, reducing stress concentrations and enhancing long-term reliability.
