Why Choose Heng Guan for Your RKS.22.0411 Slewing Ring?

Lightest in the RKS.22 family — 31 kg. At 31 kg, this light-series internal gear slewing ring is air-freight friendly. You cut overseas logistics cost and lead time significantly compared to heavier alternatives.

Factory-direct pricing. Our factory-direct price is far more competitive than distributor pricing, with MOQ of just 1 piece. That means you get the same interchangeable quality without overpaying.

In-stock and fast. Standard models ship within 3–7 days. Non-stock or custom configurations are ready in 25–30 days. Air freight is available for the 31 kg unit, making it easy to hit your project deadline.

Precision-grade materials. Raceways are induction hardened to HRC 55–62 using 42CrMo4 or 50Mn alloy steel. NBR integral seals protect from −40 °C to +110 °C, covering harsh outdoor and industrial environments.

Full customization support. Need a special coating, modified seal, or non-standard bolt pattern? Our engineering team handles OEM/ODM requests. Just send your requirements — no minimum volume needed for consultation.

Where Is the RKS.22 0411 Internal Gear Slewing Bearing Used?

Excavators and construction excavator are the primary application. The center-drive internal gear layout lets the pinion sit inside the ring, keeping the outer flange free for upper-carriage mounting. This is the classic setup for compact excavator swing bearings handling shock loads and continuous rotation.

CNC rotary tables and machining centers demand tight running accuracy. With radial ≤ 0.2 mm and axial ≤ 0.3 mm tolerances, this light-series internal gear turntable bearing delivers the precision your CNC application needs.

Casting and foundry equipment often runs in high-temperature, dusty environments. The NBR seals rated to +110 °C and induction-hardened raceways handle these tough conditions reliably.

Robot joints and automation turntables benefit from the compact center-drive design. The internal gear teeth allow a clean, space-saving drive layout — ideal for collaborative robots and pick-and-place systems.

Packaging and conveyor excavator also use this flange design with internal gear for smooth, low-noise continuous rotation in packing line turrets and indexing tables.

Packaging & Shipping

Each RKS.22.0411 Slewing Bearings unit is packed in a wooden case with rust-preventive wrapping. At 31 kg, the unit qualifies for standard air freight. We support DHL, FedEx, UPS, and sea freight consolidation for bulk orders.

FAQ

Q1: What loads can this slewing bearing handle?

A: It handles three combined loads: axial force (vertical), radial force (horizontal), and tilting moment (when the load acts off-center from the bearing axis). Always calculate the equivalent combined load — dynamic shock from sudden stops or unloading is one of the main causes of premature failure.

Q2: How do I choose between internal gear and external gear?

A: External gear bearings (like the RKS.21.0411) are easier to inspect and maintain since the gear face is visible. Internal gear bearings (like this RKS.22.0411) offer a more compact radial footprint and suit center-drive layouts. Your pinion position and available installation space are the deciding factors.

Q3: How do I re-grease correctly?

A: First, wipe the grease nipples clean before injecting. Rotate the bearing slowly while applying grease so it distributes evenly. Keep adding until fresh grease appears at the seal lips — this pushes out old grease and contaminants. Then wipe away the overflow to stop it attracting dust. A token top-up does almost nothing.

Q4: Is it normal for grease to leak from the seals?

A: A small amount of overflow during re-greasing is normal and confirms fresh grease has reached the raceway. Continuous heavy leakage, however, signals worn or damaged seals, excessive grease pressure, or abnormal clearance growth. If leakage comes with noise or rising temperature, treat it as a fault.

Q5: Can you customize for low-temperature or corrosive environments?

A: Yes. For below −40 °C applications, we use low-temperature grease and cold-rated materials. For corrosive environments, anti-corrosion coatings and multi-lip seals are available. Always tell us your operating environment — not just the part number — so we configure the bearing correctly.

Q6: How do I read the RKS.22.0411 model number?

A: In the SKF RKS series: "22" indicates the light series with internal gear; "0411" refers to the mean raceway diameter (411 mm). Different brands use different coding rules. When ordering a cross-reference replacement, always confirm with both the model number AND key dimensions (OD, ID, height) to avoid mismatch.
