Product Description

23 0411 01 Slewing Bearing – Flanged Thin-Section Solution for Space-Constrained Rotary Applications

The 23 0411 01 Slewing Bearing is a single-row four-point contact ball slewing ring from the Rollix 23 Series (Light Series), specifically engineered for applications demanding lightweight design and flange-type mounting. With an outer diameter of 518 mm, inner diameter of 304 mm, and uniform height of 56 mm, this bearing weighs only 23 kg. Its L-shaped flanged profile enables direct mounting without additional support structures, making the product ideal for small cranes, aerial work platforms, solar trackers, and radar antenna mounts where installation space is limited. The bearing features NBR double-lip seals, grease lubrication with refill ports, and raceway hardness of HRC 55-60 for reliable performance in temperatures ranging from -20℃ to +80℃.

What Makes the 23 Series Unique Among Slewing Bearings?

No other gearless slewing bearing series has integrated flange mounting surfaces like the 23 Series. The 23 Series' L-shaped flanged profile facilitates installation and assembly, unlike the rectangular cross-section 03 Series or solid-section 33 Series. This design is similar to INA VLU200xxxx and RKS.23 or Kaydon RK6.

All seven 23 Series variants are 56 mm tall, making them interchangeable in equipment with conventional mounting specifications. Instead of specialized adapter plates, the outer ring's integral flange offers a robust bolting contact.

Key Engineering Advantages

Lightweight Thin-Wall Construction: The 23 Series achieves 30-40% weight reduction compared to rectangular-section 03 Series bearings of equivalent outer diameter, directly lowering inertia and energy consumption in rotary systems.

Integrated Flange Mounting: The outer ring's machined flange eliminates custom mounting brackets. Your installation team can bolt the 23 0411 01 slewing bearing directly to the supporting structure, reducing assembly time by up to 50%.

Four-Point Contact Load Distribution: Unlike crossed-roller bearings that handle primarily radial loads, this bearing's ball-race geometry simultaneously manages axial forces, radial loads, and tilting moments within a single compact unit.

Pre-Sealed and Pre-Lubricated: Dual NBR lip seals prevent contamination ingress in dusty or humid environments. The pre-filled grease and strategically located refill ports enable maintenance without disassembly.

FAQ

Q: Can I replace a 23 0411 01 bearing with an INA VLU equivalent?

A: Yes, the 23 Series is dimensionally compatible with INA VLU200xxx series. Verify bolt hole patterns in your specific application before substitution.

Q: What is the recommended maintenance interval?

A: Re-lubricate every 500 operating hours or annually. Use lithium-based NLGI Grade 2 grease through the provided filling ports.

Q: Does this bearing support external gear-driven rotation?

A: No. No. The 23 Series is gearless. If you require integrated gearing, consider the 21 Series (external teeth) or 22 Series (internal teeth).

Q: What delivery time should I expect?

A: In-stock products ship within 7-15 days. Custom configurations take 4-6 weeks depending on intricacy.
