- Product Description
RKS.23.0841 Slewing Bearings — Light Series Ungeared Four-Point Contact Ball Slewing Ring for Crane & Heavy-Duty Rotation
If you're sourcing RKS.23.0841 Slewing Bearings, you've found the right supplier. Luoyang Heng Guan Bearing Technology Co., Ltd. is a modern enterprise with over 30 years of experience, specializing in high-precision slewing bearings from 50–10,000 mm diameter across P0, P6, P5, and P4 precision grades. This SKF RKS.23 light series ungeared turntable bearing features a 948 mm OD, 734 mm bore, 56 mm height, and 48 kg weight — combining compact dimensions with strong combined-load capacity. ISO9001 certified, RoHS compliant, exported to 50+ countries.
What Is the RKS.23.0841 / RKS.230841 Slewing Ring Bearing?
The RKS.23 0841 is a single-row four-point contact ball slewing bearing without gear, built to the SKF RKS.23 light series standard.
Its 841 mm mean raceway diameter and gearless flange design make it ideal for direct-drive turntable applications where a compact, lightweight slewing ring is needed.
Both the outer and inner rings use 18 mm through holes — no M12 threads — so it mounts cleanly onto flanged structures without extra machining.

Cross Reference & Interchange Guide
The 23.0841 shares the same engineering footprint with several well-known brand equivalents. If you're replacing any of the following, this bearing fits directly:
Brand | Part Number |
SKF | RKS.23.0841 |
INA / Schaeffler | VLU200844 / VLU200844-RL1 |
Rollix | 23-0841-01 |
Rothe Erde | 230.20.0800.013 / NBL.20.0844.200-1PPN |

The VLU200844-RL1 variant indicates special lubrication and sealing configuration — we can supply this variant with MOQ of just 1 pc. If you need a geared version, see also RKS.21.0841 (external gear) or RKS.22.0841 (internal gear).
Key Product Advantages
Gearless direct-drive design. No external or internal gear teeth means zero gear-mesh noise and reduced maintenance in direct-drive systems. Both rings feature clean 18 mm through holes for straightforward bolted assembly.
Induction-hardened raceways at HRC 55–62. The 42CrMo4 / 50Mn steel rings provide a hard, fatigue-resistant surface while the core remains tough enough to absorb shock loads — critical for crane and construction excavator cycles.
Wide operating temperature range. The NBR one-piece seal handles −40 °C to +110 °C, so whether you're working in a Norwegian winter or a Middle Eastern summer, this gearless four-point contact ball slewing ring keeps performing.
Air-freight feasible at 48 kg. At just 48 kg, the 0841 is the largest bearing in the RKS.23 mid-range that remains practical to air-ship, which opens faster delivery options for urgent overseas projects.
Typical Application Areas
The RKS.23.0841 Slewing Bearings 948×734×56 mm slewing ring is widely used across these industries:
· Crane & lifting equipment — turntable rotation under combined axial, radial, and tilting moment loads
· Road rollers & construction excavator — ungeared slewing joints requiring simple, durable rotation
· Robot palletizers & logistics automation — large direct-drive turntable bearing in high-cycle environments
· Solar tracker systems — slow-speed, low-maintenance slew bearing without gear for single-axis trackers
· Large direct-drive rotary mechanisms — any application where a light duty direct drive turntable bearing with a clean flange interface is preferred
