Full Technical Specifications of RKS.23 0741 Slewing Bearing

This bearing — also catalogued as RKS.230741 or simply 23.0741 — is a single-row four-point contact ball slewing ring without gear. It handles combined axial, radial, and tilting moment loads in a compact, lightweight profile.

Cross-Reference & Interchange Guide

If you're sourcing a direct replacement, this bearing is fully interchangeable with the following:

Key Performance Advantages

Why do engineers choose this ungeared turntable bearing?

The gearless four-point contact ball design makes it ideal for direct-drive systems where a motor or actuator connects directly to the ring. Both inner and outer rings feature 18 mm through holes — no M12 threads — so your mounting is clean and straightforward.

The 20 mm balls in a four-point contact arrangement distribute loads across four contact points simultaneously. That means combined axial, radial, and tilting moment loads are all handled in a single, space-saving row.

The NBR one-piece seal handles temperatures from −40 °C to +110 °C, making this bearing suitable for both Arctic offshore environments and high-temperature industrial settings. Four AM8×1 grease nipples on the inner ring ensure you can re-lubricate easily during maintenance.

Typical Application Scenarios

This light-series flange-type slewing ring excels in low-speed, high-load rotation. Here's where you'll typically find it at work:

· Offshore cranes & port handling equipment — the ungeared design suits direct-drive slew systems where weight matters

· Robot palletizers & logistics automation — smooth, low-noise rotation keeps cycle times consistent

· Road rollers & construction excavator — robust raceway hardness withstands shock and vibration

· Solar trackers — the lightweight profile reduces drive motor requirements for large-aperture single-axis trackers

· Large direct-drive turntables — medical positioning tables, radar platforms, and precision indexing systems

Customization & Variant Options

You're not locked into a single configuration. We support:

· Seal material upgrade — FKM seals available for chemical or high-temperature environments

· Lubrication customization — alternative grease grades for extreme-cold or food-grade applications

· Variant family — RL0, RL3, VSP, and ZT variants aligned to INA VLU200744 series specifications

· Ring material selection — C45E for general use, 42CrMo4 or 50Mn for higher toughness demands

· OEM/ODM — custom marking, packaging, and dimensional modifications available; MOQ 1 pc

Non-standard configurations typically deliver in 25–30 days. We provide installation guidance and technical consultation throughout your project.

Quality Assurance You Can Trust

Every bearing we produce goes through a strict multi-stage inspection process. We use coordinate measuring machines, vibration testers, and life testing machines to verify dimensional accuracy, hardness, and performance before shipment.

Raw materials carry full traceability from mill certificate to finished product. Our ISO9001-certified quality system and RoHS-compliant manufacturing mean your supply chain documentation is always in order.

We've shipped to customers in the United States, Germany, the United Kingdom, Norway, Australia, and 45+ other countries. Bulk orders are well within our capacity — a documented 50-piece order for this exact bearing size confirms our readiness for high-volume supply.

FAQ

Q: What is RKS.23.0741?

A: It is a light series single-row four-point contact ball slewing bearing without gear, built to SKF RKS.23 standard. Key dimensions: 741 mm mean raceway diameter, 634 mm bore, 848 mm OD, 56 mm height, 43 kg weight.

Q: What are the exact dimensions of the RKS.23.0741?

A: Bore 634 mm (+0.6/0), outside diameter 848 mm (0/−0.6), height 56 mm (±1 mm). Bolt circles: outer 820 mm with 12 × 18 mm holes; inner 662 mm with 16 × 18 mm holes.

Q: Is the RKS.23.0741 equivalent to INA VLU200744?

A: Yes. INA VLU200744 and its variants — VLU200744-RL0, -RL3, -VSP, and -ZT — are confirmed interchangeable replacements. Rollix 23-0741-01, Rothe Erde 230.20.0700.013, and TGB 90-20 0741 are also direct equivalents.
