Key Product Advantages of the RKS.23.0641 Light Series

This RKS.23.0641 Slewing Bearings isn't just a standard replacement — it brings real performance benefits to your machine design.

Gearless flange design for direct-drive layouts. Both the outer and inner rings use 18 mm through holes (no M12 threads). This makes it ideal for externally driven or direct-drive turntable applications where no integrated gear is needed.

Four-point contact ball design. The single-row, 20 mm ball configuration handles combined axial, radial, and tilting moment loads simultaneously — a smart, compact solution for light-duty rotation.

Induction-hardened raceways. At HRC 55–62, the raceway surface resists fatigue and wear, while the core stays tough enough to absorb shock. Material options include C45E, 42CrMo4, or 50Mn to match your load and environment.

Wide operating temperature range. The NBR one-piece seal handles −40 to +110 °C without leaking grease or allowing contamination. Combined with NLGI 2 lithium EP grease and four dedicated nipples, re-lubrication is straightforward.

Air-freight feasible at 36.5 kg. The light series footprint keeps logistics simple for urgent replacements or low-volume orders.

Typical Application Scenarios for Gearless Four-Point Contact Slewing Rings

This bearing is widely used across industries where smooth, low-speed rotation under combined loads is required.

· Robot palletizers & logistics automation — the 748×534×56 mm gearless slewing ring is the go-to core component for palletizing robot turntables

· Solar trackers — low-speed, continuous outdoor rotation suits the NBR seal and EP grease spec

· Medical CT scanners — low noise, high running accuracy, and smooth rotation meet precision imaging demands

· Filling & packaging machines — light-series direct-drive turntable bearing for indexing and rotating platforms

· Crane and industrial turntables — ungeared design simplifies the drive system and reduces overall machine weight

Why Source Your RKS.23.0641 Slewing Bearings from Heng Guan?

You have plenty of choices. Here's what makes working with us different.

Our engineers carry over 30 years of slewing bearing experience. We manufacture diameters from 50 mm to 10,000 mm with precision grades P0, P6, P5, and P4 — so we understand your tolerances, not just your model number.

Every bearing goes through coordinate measuring machines, vibration testers, and life-test equipment before it ships. Full material-to-finished-product traceability is standard, not optional.

We support OEM/ODM partnerships, old-product mapping, and non-standard customization. Whether you need one piece or a bulk shipment, we ship standard stock in 3–7 days and non-stock models in 25–30 days.

Our products have been exported to 50+ countries including the United States, Germany, Australia, and the Middle East — trusted by international customers who need reliability and responsive service.

FAQ

Q: What is RKS.23.0641?

A: It is a light-series, single-row, four-point contact ball slewing bearing without gear, built to the SKF RKS.23 standard. Mean raceway diameter is 641 mm, bore 534 mm, OD 748 mm, height 56 mm, and weight 36.5 kg.

Q: What are the exact dimensions and tolerances?

A: Bore: 534 mm (21.02 in), tolerance +0.6/0. OD: 748 mm (29.45 in), tolerance 0/−0.6 mm. Height: 56 mm (2.20 in), tolerance ±1 mm. Bolt circles: 720 mm outer (12 × 18 mm holes) and 562 mm inner (16 × 18 mm holes).

Q: Is RKS.23.0641 equivalent to INA VLU200644?

A: Yes. INA VLU200644 and VLU200644-RL0 (Schaeffler) are confirmed interchangeable — and the VLU200644 is listed as remanufacturable per Schaeffler medias. Kaydon RK6-25P1Z, Rollix 23-0641-01, and Rothe Erde 230.20.0600 / 013.25.560 are also drop-in replacements.

Q: What is the load capacity?

A: Dynamic axial load rating C = 200 kN; static axial load rating C0 = 440 kN. The four-point contact design handles combined axial, radial, and tilting moment loads simultaneously.

Q: Is it in stock? What is the lead time?

A: Stock units ship within 3–7 days. Non-stock standard models typically ship in 25–30 days. MOQ is 1 pc. Contact Us for current availability and factory-direct pricing.

Q: Can the bearing be remanufactured or reconditioned?

A: Yes. As confirmed by Schaeffler's medias listing (VLU200644 marked remanufacturable), large-diameter slewing bearings like the RKS.23.0641 can be remanufactured — raceways reground, rolling elements replaced, seals renewed — provided core material fatigue limits are not exceeded.
