RKS.23.0411 Slewing Bearings
• Official INA cross — INA VLU200414 is listed in Schaeffler medias (with VLU200414-ZT variant at Misumi), so the VLU search path lands on our page, not the OEM's.
• Lightest RKS.23 model at 23.5 kg — air-freight friendly and 23.5 kg is also the rubix-listed logistic weight (23500 g); LYHY MIC video page mis-lists 1.35 kg — we ship to the catalogue (23.5 kg is the trust weapon).
• Price anchor — Misumi Europe sells VLU200414-ZT at EUR 2,762.82 (EUR 3,287.76 incl. tax) with a 68-day lead time; our factory-direct stock ships in days from China.
• Bulk proven — efindbearing 2023-08 shipped 250 pcs of RKS.23.0411 without-gear units to India, the only documented bulk order for this size.
• Drop-in replacement — INA VLU200414 / VLU200414-ZT, Kaydon RK6-16P1Z, Rollix 23-0411-01, Rothe Erde 230.20.0400 / SD.505.20.00 and TGB 90-200411 (seven-number interchange, confirmed on Alibaba Dual-Flange table).
• Truck crane / robot palletizer dual scenario — LYHY MIC evidence for "Used for Truck Cranes" plus the 23-series palletizer lineage (0541/0741 carry the palletizer tag).

Key Product Advantages of This Gearless Four Point Contact Ball Slewing Bearing
Lightest in the RKS.23 series. At just 23.5 kg, RKS.23.0411 Slewing Bearings is air-freight friendly and easy to handle on-site. This keeps your logistics costs low and delivery timelines short.
Direct-drive ready design. Both the outer and inner rings feature 18 mm through holes — no M12 threads, unlike the RKS.21/22 geared variants. This makes the bearing ideal for external motor or direct-drive setups.
Outstanding load capacity for its size. With a dynamic rating of C = 169 kN and static rating of C0 = 284 kN, this single-row bearing handles combined axial, radial, and tilting moment loads with confidence.
Induction-hardened raceways. The raceway surface reaches HRC 55–62, while the core remains tough enough to absorb shock loads. This gives you excellent fatigue resistance and a long service life.
Reliable sealing and lubrication. The NBR one-piece seal operates from –40 °C to +110 °C. Four grease nipples on the inner ring make re-lubrication straightforward, even in the field.

Typical Applications of the RKS.23 Light Series Ungeared Turntable Bearing
This compact, gearless slewing ring fits a wide range of industries:
· Truck cranes & mobile cranes — handles combined loads with shock resistance in heavy lifting environments
· Robot palletizers & logistics automation — smooth, precise rotation for repetitive high-cycle operations
· Filling & packaging excavator — low-noise, compact footprint for high-speed production lines
· Medical & precision equipment — quiet running, high accuracy, and vibration-free rotation
· Solar trackers — reliable low-speed rotation with minimal maintenance requirements
The 518×304×56 mm footprint and 23.5 kg weight make it particularly attractive wherever space and weight are a concern.
