RKS.122290101002 Slewing Bearings

RKS.122290101002 Crossed Cylindrical Roller Slewing Bearing – External Gear Solution for High-Precision Rotation

Luoyang Heng Guan Bearing Technology Co., Ltd. manufactures the RKS.122290101002 Slewing Bearings, a customized crossed cylindrical roller turntable bearing with external gear designed for high-precision, high-load applications. With over 30 years of bearing expertise in Luoyang, China's bearing industry hub, our ISO9001-certified facility produces this 571 mm bore × 816 mm OD × 90 mm height bearing with a 117 kg weight, 495 kN dynamic load rating, and 1880 kN static axial capacity. The module 6 / 132-tooth external gear provides fine-pitch, low-clearance engagement for precise positioning and smoother positioning for industrial robots, CNC rotary tables, and CT scanners. Our precision grades cover P0, P6, P5 and P4, and we serve over 50 countries across Europe, North America, and Asia.

What Makes the RKS.122290101002 Stand Out?

The RKS 122290101002 is a direct SKF-compatible replacement, listed with mrosupply (SKU 2067485) and RS Components (SKU 73244397) in global supply chains. Unlike standard ball bearings, this crossed roller slewing ring bearing simultaneously handles axial force, tilting moments, and radial loads through 90° crossed GCr15 cylindrical rollers.

The 675 mm mean raceway diameter and module 6 gearing enable precision positioning in compact spaces. You'll find this bearing in radar antenna mounts, semiconductor wafer alignment platforms, and tank turrets—applications where micron-level accuracy meets harsh operating conditions.

Our team of 50+ engineers uses CNC vertical lathes, quenching machines, and gear shapers to manufacture each bearing. Every RKS.122290101002 external gear crossed roller slewing bearing undergoes coordinate measurement and vibration testing before shipment. We maintain full traceability from raw 50Mn/42CrMo4 ring material through final NBR seal installation.

Technical Specifications

Why Choose Our Crossed Roller Slewing Ring Bearing?

Fine-Pitch Gearing for Precision

The module 6 / 132-tooth configuration delivers reduced clearance, smoother pinion engagement, and repeatable positioning accuracy—critical when your CNC rotary table or robotic arm demands micron-level control.

Three-Source Verified Load Ratings

We've confirmed the 495 kN dynamic and 1880 kN static axial load ratings through independent testing, SKF catalogue cross-referencing, and fatigue curve validation. You get reliable data for your safety factor calculations, not guesswork.

Unequally Spaced Bolt Pattern Documented

The inner ring's 35 × Ø22 mm through-holes on a 604 mm circle are unequally spaced to avoid resonance and simplify angular indexing. We provide drilling templates and CAD drawings to match your mounting flange—no trial-and-error during installation.

US & European Distribution Compatibility

If you're replacing an original SKF bearing sourced through mrosupply or RS Components, our 122290101002 matches their dimensional standard exactly. Compare our factory-direct pricing against the USD 8,903.64 distributor list price and see the difference.

Stock Availability & Fast Shipping

Standard models ship in 2–3 days from our Luoyang facility. MOQ is just 1 piece—whether you need a single replacement or bulk order for an OEM production line. We support FOB, CIF, and DDP terms to over 50 countries.

Where You'll Use the RKS.122290101002 816×571×90mm?

Industrial Robots & CNC Rotary Tables

Your robot's wrist joint or your machining center's fourth axis relies on crossed roller rigidity to hold position under cutting forces. The low frictional torque supports frequent start-stop cycles without drift, ensuring consistent part tolerances batch after batch.

Radar Antenna Mounts & Tank Turrets

Military precision demands stable rotation in sandstorms, arctic cold, and high-shock environments. The NBR double-lip seals keep contaminants out while the 50Mn ring material absorbs impact loads—perfect for azimuth drives that must hit targets reliably.

CT Scanners & Medical Imaging

Patient diagnostics require whisper-quiet rotation and zero vibration. The crossed roller turntable bearing 571×816×90 delivers smooth motion at low speeds, and our P5-grade option (available on request) meets medical equipment standards for runout control.

Photovoltaic & Semiconductor Wafer Alignment

When you're positioning 300 mm silicon wafers or solar cells under microscopes, micron-level accuracy isn't optional. The high rigidity and low rotational runout of this single-row crossed roller slewing bearing external gear enable the repeatability your yield rates depend on.

Cranes & Excavators

The 1880 kN static load capacity handles boom tilting moments and impact loads from bucket dig cycles. The external gear meshes directly with your slew drive pinion—no additional gearbox complexity—reducing maintenance points on jobsites.

Aerospace Simulation Turntables

Flight simulator motion platforms and satellite test rigs demand precision angle changes under combined loads. Our P5/P4-grade options (50–10,000 mm diameter range) meet aerospace cleanliness and documentation requirements.

US Aftermarket Replacement

Buyers replacing an SKF RKS.122290101002 from mrosupply (SKU 2067485) or RS Components (SKU 73244397) get the identical 35-hole inner pattern and gear profile shift (x·m 6.552 mm / k·m 0.552 mm) from our factory—at a fraction of distributor pricing. Real buyer inquiries from Kuwait SKF agencies and private US customers confirm field demand.

Custom Capabilities & Engineering Support

Beyond the standard RKS.122290101002 Slewing Bearings customized crossed cylindrical roller, we offer:

· Non-standard sizes: 50–10,000 mm diameter, adapted to your mounting envelope

· Precision grades: P0, P6, P5, P4 for varying accuracy requirements

· Gear variations: internal gear, no-gear (compare with RKS.122295101002), or modified profile shifts

· Material upgrades: 42CrMo4 quenched rings, FKM seals for +200 °C, corrosion-resistant coatings

Our engineers provide 24-hour response on interchange checks (adjacent sizes RKS.121390101002 / RKS.221310101001, non-standard numbers V25E197 / V25S085 / HJB675X1), installation guidance, and old-product mapping when you lack 3D models. We handle OEM/ODM partnerships for mining equipment, wind turbines, and automation lines.

Packaging & Quality Control

Each cross roller slewing ring bearing with outer gears ships in fumigated wooden crates with rust-preventive VCI film and shock-absorbing foam. We label crates with model number, serial number, and QR-coded test reports for full traceability.

Before dispatch, our quality team performs:

· Coordinate measurement of raceway geometry (runout, diameter deviation)

· Vibration testing to detect roller defects

· Gear tooth profile verification (DIN 3962 Grade 6)

· Seal pressure testing (double-lip NBR to -40 °C)

You receive bearing passports with measured values, material certificates (50Mn / 42CrMo4 mill sheets), and ISO9001/RoHS compliance documents—everything your quality department needs for incoming inspection.
