RKS.23 0411 Four Point Contact Slewing Ring Bearing for Heavy-Duty Applications

The RKS.23 0411 is a four point contact ball slewing ring bearing designed for demanding machinery and energy systems. With a compact structure and a single row of balls that make four-point contact with the raceways, it can carry axial, radial, and tilting moment loads at the same time.


Core Features at a Glance

  • Four-point contact design handles multi-directional loads with ease

  • Outer diameter approx. 411 mm (check datasheet for exact figures)

  • Manufactured from quenched and tempered alloy steel, raceways hardened and ground

  • Gear options: internal, external, or gearless

  • Grease lubrication with relubrication channels for extended service life


Built for Demanding Environments

Unlike conventional bearings, the RKS.23 0411 offers stability in systems where compact dimensions are critical but load requirements are high. Its raceway design provides durability against fatigue, while the optional gear configurations give engineers freedom to integrate it into different drive systems. With proper lubrication, it maintains consistent performance even under heavy-duty or outdoor conditions.


Typical Applications

Cranes and lifting equipment rely on the RKS.23 0411 for smooth slewing under heavy axial forces. Excavators and construction machinery use it to maintain reliable rotation during intensive cycles. Wind turbines take advantage of its ability to manage moment loads generated by blades, while medical imaging equipment and industrial automation benefit from its precise and controlled motion.


Why Engineers Choose It

The RKS.23 0411 strikes a balance that many procurement teams seek:

  • Compact size without compromising load capacity

  • Flexibility in system integration thanks to gear variations

  • Predictable performance and long service intervals with proper maintenance

These qualities not only reduce downtime but also lower the overall cost of ownership in critical equipment.


In summary, the RKS.23 0411 four point contact ball slewing ring bearing is a dependable solution for industries where stability, efficiency, and durability are essential. For detailed technical data or pricing, contact Bearing Maker for full support.
