Cross Reference & Interchange for RKS.23 0541

Looking for a direct replacement? You're in the right place.

The RKS.23.0541 is fully interchangeable with several globally recognized part numbers. You can source it as a drop-in substitute without modifying your mounting structure.

If you're currently using an INA VLU200544 equivalent, our RKS.23.0541 slewing ring is a certified factory-direct alternative — same dimensions, same bolt pattern, same performance.

Product Features & Design Advantages

This gearless four-point contact ball slewing bearing is engineered for combined axial, radial, and tilting moment loads in a compact, lightweight package.

Here's what makes it stand out:

· Ungeared / no-gear design — Both rings use 18 mm through holes with no M12 threads. This makes it direct-drive ready and easy to integrate.

· Four-point contact ball — A single-row 20 mm ball design handles multi-directional loads efficiently without adding bulk.

· Induction-hardened raceways — HRC 55–62 surface hardness for excellent fatigue resistance, while the core stays ductile to absorb shock.

· NBR one-piece seal — Rated from –40 to +110 °C, it keeps grease in and contaminants out in tough environments.

· Only 31 kg — Air-freight friendly and easy to handle on-site. Perfect for projects with tight logistics requirements.

· 4 × AM8×1 grease nipples — Pre-positioned on the inner ring for straightforward maintenance scheduling.

Application Areas

The RKS.23.0541 Slewing Bearings performs reliably across multiple industries:

Robot Palletizers & Logistics Automation (Primary)

This is the part's most prominent application. It serves as the rotary joint in palletizing robot arms, where slow oscillating motion, precise positioning, and low maintenance are all critical.

Construction Excavator

As a non-geared flange slewing bearing, it connects rotating upper structures to undercarriages on compact construction equipment. It handles shock and vibration without compromising stability.

Crane Accessories

Used as a replacement slewing ring in crane accessories where a lightweight, ungeared turntable bearing is needed for secondary rotation points.

Filling & Packaging Machines

Light-series performance suits high-frequency, low-load rotary tables in filling lines and packaging automation.

Solar Trackers & General Industrial Turntables

Its slow-speed precision and sealed design make it suitable for solar tracker slew bearings and general-purpose automation turntables.

FAQ

Q1: What is RKS.23.0541?

A: It is a light-series single-row four-point contact ball slewing bearing without gear, built to the SKF RKS.23 standard. With a 541 mm mean raceway diameter, 648 mm OD, 434 mm bore, and 56 mm height, it weighs 31 kg and handles combined axial, radial, and tilting moment loads.

Q2: What are the exact dimensions of the RKS.23 0541?

A: Bore 434 mm (17.09 in), outside diameter 648 mm (25.51 in), height 56 mm (2.20 in). Outer bolt circle is 620 mm with 10 × 18 mm through holes; inner bolt circle is 462 mm with 14 × 18 mm through holes.

Q3: Is RKS.23.0541 equivalent to INA VLU200544?

A: Yes. The INA VLU200544 (Schaeffler official), Kaydon RK6-22P1Z, Rollix 23-0541-01, and Rothe Erde 230.20.0500 are all direct interchange equivalents. If you need a geared version, look at RKS.21.0541 (external gear) or RKS.22.0541 (internal gear).

Q4: What is the load capacity?

A: Dynamic axial load rating C = 188 kN; static axial load rating C0 = 380 kN. The four-point contact design carries combined axial, radial, and tilting moment loads simultaneously.

Q5: Is RKS.23.0541 in stock? How fast can it ship?

A: Stock models ship within 3–7 days. Non-stock standard models typically take 25–30 days. MOQ is 1 pc. A free 3D CAD model is available on request. Contact Us for real-time availability and factory-direct pricing.
