RKS.222500101001 Slewing Bearings
It is a direct replacement for the SKF RKS.222500101001 dimensional standard (Lily Bearing cross-reference LRKS.222500101001; Applied Item #101467697 with UPC 7316570481006 and mrosupply SKU 2066338 listed at USD 15,907.23 in the US). Customized 12-digit references have no INA/Kaydon catalogue counterpart, so same-size-band comparison (no-gear version RKS.223475101001, adjacent sizes RKS.221310101001 / RKS.221300101001) plus our engineering confirmation within 24 hours is used for interchangeability checks. The 90-degree crossed roller raceway simultaneously carries axial force, overturning moment and large radial loads with high rigidity, and the external gear (module 10, 94 teeth) allows direct pinion drive.

Key Advantages of Crossed Roller Turntable Bearing 715x979x100
High Rigidity in Compact Envelope: The crossed roller configuration delivers superior stiffness compared to ball-type slew rings. You gain multi-directional load capacity without increasing bearing height – critical when vertical space constrains your design.
US Distribution Compatibility: This SKF customized crossed cylindrical roller slewing bearing external gear model directly interchanges with Applied Item #101467697 and mrosupply SKU 2066338 (listed at USD 15,907.23). As a China manufacturer, we supply identical dimensional standards at factory-direct pricing, typically 40-60% below US distributor rates.
Precision Bolt Pattern for Drop-In Replacement: The unequally-spaced 28-hole mounting pattern matches OEM specifications exactly. You receive a drilling template with each bearing to ensure perfect alignment during installation, eliminating field modification and reducing assembly time.
Verified Load Data: Both dynamic (558kN) and static (2330kN) ratings are dual-source verified against SKF catalogue data and bearing specification databases. This gives your engineering team confidence when calculating safety factors for crane slewing bearing crossed roller applications or excavator rotary bearing crossed roller installations.
Weight Transparency: We document net weight (180kg) separately from shipping weight (~197kg with export crate). This clarifies payload calculations and prevents installation surprises when comparing against the 434.31 lb US distribution listing.
Fast Delivery with MOQ 1: Standard models ship within 2-3 days from our Luoyang facility. We maintain inventory of high-demand sizes and support single-piece orders, unlike distributors requiring bulk minimums.

Application Areas for the RKS.222500101001 External Gear Crossed Roller Bearing
Crane & Excavator Rotation Systems
The RKS.222500101001 Slewing Bearings crossed roller turntable bearing excels in crane slewing bearing crossed roller and excavator rotary bearing crossed roller applications. The 2330kN static load rating handles boom-down parking loads, while the external gear withstands peak tooth forces of 136kN during swing acceleration. Heavy equipment service teams choose this cross roller slewing ring bearing with outer gears for predictable lifecycle and field replaceability.
Industrial Robot Joints & Rotary Tables
For industrial robot slewing bearing crossed roller and precision rotary table slewing bearing crossed roller installations, the 90-degree roller orientation provides the repeatable positioning accuracy automation demands. You achieve ±0.02mm runout over 360° rotation, essential for welding robots and five-axis machining centers where tool path precision determines part quality.
Medical Imaging Equipment
Medical device slewing bearing crossed roller applications in CT scanners and MRI gantries require whisper-quiet, smooth rotation in controlled environments. The sealed long life crossed roller slewing bearing design with NBR double-lip protection prevents particle generation, meeting stringent cleanroom standards while supporting 200-300kg patient loads through thousands of imaging cycles.
Solar Tracking & Wind Energy
Solar tracker crossed roller bearing and wind turbine yaw crossed roller bearing installations subject bearings to continuous outdoor exposure. The C45E ring material accepts protective surface treatments, and the high-stiffness design minimizes deflection under wind loading. You reduce maintenance intervals in remote installations where downtime costs escalate quickly.
Aerial Work Platforms
The 100mm height envelope makes this aerial work platform slewing bearing ideal for boom lifts where vertical space directly impacts working height specifications. The compact single row crossed roller slewing bearing external gear configuration delivers 360° rotation without sacrificing lift capacity or platform stability.
US Aftermarket Replacement Programs
As US distributors list this model with established part numbers (Applied #101467697, mrosupply #2066338), aftermarket buyers gain supply chain confidence. We provide the RKS.222500101001 replacement / interchange / equivalent / cross reference with full dimensional certification, including the critical unequally-spaced bolt pattern that ensures compatibility with existing mounting structures.
Manufacturing Excellence and Quality Control
Our Luoyang facility operates advanced CNC vertical lathes, CNC quenching machines, and CNC gear shapers to maintain tight tolerances across the 979mm outside diameter. Every customized crossed roller slewing ring bearing undergoes coordinate measuring machine verification of raceway geometry and vibration testing to ISO standards.
The heat treatment process creates 55-62 HRC surface hardness on raceways while maintaining core ductility for shock absorption. We achieve P5 and P4 precision grades when your application demands enhanced rotational accuracy. Full material traceability from raw steel through final inspection ensures RoHS compliance and meets international bearing standards.
Our gear cutting department machines the module-10 external teeth with 11mm profile shift to optimize tooth contact patterns. Each gear undergoes tooth force validation to confirm the specified 74kN normal / 136kN maximum loading capacity before shipment.

Installation Guidance and Technical Support
Mounting Surface Preparation: Machine mounting surfaces flat within 0.05mm over the bolt circle diameter. Clean all surfaces thoroughly and apply a thin rust-preventive oil layer before positioning the bearing. Align the S-mark (soft spot in the hardening zone) to the minimum load sector of your application.
Bolt Tightening Procedure: Use grade 10.9 or 12.9 high-strength bolts. Apply the specified preload torque in a star pattern across all 28 mounting positions (both inner and outer rings). Re-torque after initial 50 hours of operation to compensate for initial settling.
Lubrication Protocol: Fill the lubrication grooves with lithium-based NLGI Grade 2 grease before first operation. Establish a 100-hour re-lubrication schedule for raceway maintenance and 50-hour intervals for the external gear when operating in dusty environments. Our engineering team can recommend automatic lubrication systems for continuous-duty installations.
Clearance Measurement: Monitor axial and radial clearance every 500 operating hours. If measured clearance exceeds 1.5× the initial factory specification, contact our technical team to assess remaining service life and plan replacement.
We provide CAD drawings, 3D models, and installation templates with every order. Our 50+ person engineering team offers 24-hour response for technical consultation, helping you optimize bearing selection for your specific load conditions and duty cycles.

Contact mia@hgb-bearing.com with your required delivery date for current stock status and expedited shipping options.
Q: How does this bearing compare to ball-type slewing rings?
A: The crossed roller design provides 2-3× higher rigidity than four-point contact ball bearings of similar size. You gain better resistance to tilting moments and more predictable load distribution. However, ball bearings offer higher speed capability. For crane and excavator applications operating below 50 RPM, the crossed roller configuration delivers superior performance and longer service life.
