Technical Specifications

Our RKS 512080101001 offers precise engineering data verified against SKF catalogue standards. You can rely on these specifications for your design calculations and interchangeability assessments.

Design Advantages and Engineering Benefits

The RKS.512080101001 internal gear design positions the drive pinion inside the bearing ring, creating a compact mechanism that protects tooth surfaces from environmental debris. This configuration is particularly valuable when you need to maintain a clean machine envelope.

Your equipment benefits from 90-degree crossed cylindrical rollers that deliver superior rigidity under combined loads. The bearing handles axial forces, radial loads, and tilting moments simultaneously—essential for precision rotary applications.

With module 5 gearing and 420 teeth, you receive ultra-smooth engagement and Optimal working clearance. The high tooth count distributes drive forces evenly across the gear mesh, extending service life in demanding duty cycles.

Our threaded mounting system provides installation flexibility. Thirty-six M14 bolts on dual circles (2262/2142 mm) allow you to achieve proper preload without specialized hydraulic tools.

The static load capacity of 5680 kN represents the highest rating in this bearing family. You can specify this customized crossed cylindrical roller bearing for applications where shock loads and tilting moments are primary design concerns.

Where You Can Apply This Large Diameter Internal Gear Slewing Bearing

Radial Rotary Tables

When you're designing radial rotary table slewing bearings, the 512080101001 provides the 2.2-meter capacity your large workpieces demand. The internal gear couples directly to your table-top drive motor, keeping your mechanism compact while the crossed roller rigidity carries heavy machining loads without deflection.

Milling Machine Worktables

Your milling machine slewing bearing internal gear application requires smooth indexing under continuous cutting forces. The hardened module 5 teeth (420-tooth count) deliver precise positioning, while the 2290x2091x70mm envelope accommodates the large components you need to machine.

Wind Turbine Yaw Systems

As a wind turbine internal gear slewing bearing, this reference suits nacelle yaw drives where you need reliable rotation into prevailing wind. The 5680 kN static capacity resists storm loads and extreme weather events that would overload smaller bearings.

Ship Cranes and Port Excavator

Your ship crane internal gear slewing bearing demands both high tilting moment resistance and corrosion protection. This bearing family has documented service in marine duty, where the internal gear design protects the mesh from salt spray and deck debris.

Mining and Tunnel Boring Equipment

For mining equipment rotary table bearing and tunnel boring machine slewing bearing applications, you face abrasive environments and massive rotation loads. The protected internal gear and 2.2-meter-class capacity deliver the durability your heavy equipment requires.

Replacement Market

Listed in LKPB replacement tables and cross-referenced by QIBR, the RKS.512080101001 replacement serves aftermarket needs. We supply the identical SKF-compatible bearing—including the 36 × M14 threaded bolt pattern—at factory-direct pricing.

Manufacturing Excellence and Quality Control

You receive bearings manufactured on CNC vertical lathes, CNC quenching machines, and precision gear shapers. Our heat treatment process hardens raceways to 55-62 HRC while maintaining core toughness to absorb shock loads.

Every RKS.512080101001 slewing ring bearing undergoes coordinate measuring machine inspection, vibration testing, and dimensional verification before shipment. We provide full traceability from raw material 42CrMo/50Mn ingots through final assembly.

Our factory in Luoyang—China's bearing industry hub—combines advanced equipment with skilled craftsmen. This integration allows us to deliver both standard SKF-compatible models and personalized non-standard customization for your unique applications.
