What Is the RKS.23.0941 – SKF RKS.23 Light Series Ungeared Turntable Bearing?
The RKS.23 0941 is a single-row, four-point contact ball slewing ring belonging to SKF's RKS.23 light series. It carries combined axial, radial, and tilting moment loads in a compact, ungeared design.
Both inner and outer rings feature 18 mm through holes — no M12 threads — making it a true direct-drive turntable bearing. The inner-ring flange design simplifies mounting on road rollers, robot palletizers, solar trackers, radar antennas, and large filling machine turntables.
At 54 kg and just 56 mm tall, this bearing delivers heavy-duty performance in a light footprint. If you need a drop-in replacement for INA VLU200944, Kaydon L6-37P9Z, or Rollix 23-0941-01, this is your match.

Key Product Advantages
Ungeared Direct-Drive Design
No gear teeth means lower weight and simpler integration for direct-drive systems. Both rings use 18 mm through holes for clean, fast bolting.
Cold-Resistant & Sealed on Both Sides
The NBR one-piece seal handles –40 °C to +110 °C. Whether you're running construction excavator in a Scandinavian winter or a solar tracker in the Middle East desert, this bearing stays protected.
Induction-Hardened Raceways
HRC 55–62 surface hardness on 42CrMo4 / 50Mn steel delivers excellent wear resistance and a long service life — even under shock and vibration loading.
Published Tolerance Data
Bore tolerance: +0.7/0 mm. OD tolerance: 0/–0.7 mm. You get full dimensional transparency for confident engineering and procurement decisions.
Typical Application Areas
The RKS.23.0941 Slewing Bearings four-point contact ball slewing ring without gear performs reliably across demanding industries:
· Road Rollers & Construction Excavator — high shock resistance, sealed protection against debris
· Large Direct-Drive Turntable Systems — ungeared flange design enables clean torque transmission
· Robot Palletizers & Logistics Automation — compact height with strong moment capacity
· Solar Trackers — corrosion-resistant, low-maintenance under continuous slow rotation
· Radar Antennas & Positioning Systems — high running accuracy (radial ≤ 0.2 mm)
· Large Filling & Packaging Lines — smooth, low-noise rotation for high-cycle operation
