Technical Specifications of 161.40.2000.890.11.1503
The 161.40.2000 slewing bearing is a single-row crossed cylindrical roller design with V-raceway geometry, optimized for high axial and radial load capacity in compact vertical space. Each 40mm diameter roller (100Cr6 through-hardened steel) crosses at 90° to adjacent rollers, delivering exceptional stiffness and moment resistance.
The bearing structure uses 50Mn or 42CrMo ring material with induction-hardened raceways (55-62 HRC surface), while rollers are manufactured from 100Cr6 bearing steel. This material combination ensures core toughness to absorb shock loads while maintaining wear-resistant running surfaces.

Cross-Reference and Interchangeability
The 161.40.2000 crossed roller slewing bearing external gear directly replaces Rothe Erde 161 series originals and matches the XOU40/2000 designation used by parallel Chinese manufacturers.
For design engineers comparing adjacent models: the 161.36.2000.890.11.1503 shares the same 2,000mm raceway diameter but uses smaller 36mm rollers, while 161.40.2128.890.11.1503 employs the same 40mm roller diameter with a larger 2,128mm raceway. If you're upgrading from a 161.28.1500 system, this 40mm roller version provides increased load capacity.
Our aftermarket 161.40.2000 replacement Rothe Erde solution delivers identical mounting dimensions and gear specifications, ensuring drop-in compatibility without machine modification. We maintain full traceability with material certificates per EN 10204 3.1 standards.
Performance Advantages of 161 Series External Gear Crossed Roller Design
The crossed cylindrical roller slewing bearing 2000mm raceway design delivers superior stiffness compared to four-point contact ball bearings of similar size. By orienting rollers at 90° alternation, you achieve line contact across the entire raceway width rather than point contact, distributing loads more evenly.
This 161 series external gear crossed roller 40mm roller configuration provides lower frictional torque during rotation, reducing drive motor requirements by 15-20% compared to ball bearing equivalents. The V-raceway profile maintains precise roller positioning without cages, enabling higher load ratings in the compact 108mm height envelope.
For the normalized gear variant (.890), permissible tooth forces reach 98.4kN continuous and 196.8kN peak. Specifying the .891 quenched and tempered (Q&T) gear option further increases permissible tooth forces, ideal for frequent start-stop cycles in crane and excavator applications.
The large diameter crossed roller slewing ring 2252.8mm OD accommodates a 98mm wide external gear with module 16 teeth, machined to ISO 1328 quality standards. This robust gearing handles high torque transmission while the 2,110mm outer bolt circle with 42×M30 mounting holes simplifies installation on your equipment structure.
Industrial Applications for Large Diameter Slewing Bearings
The 161.40.2000.890.11.1503 Slewing Bearings serve as critical rotating interfaces in heavy excavator where you need simultaneous support of axial loads, radial loads, and tilting moments. Our customers integrate these bearings into diverse industrial environments.
Crane slewing bearing 161.40.2000 large applications include mobile cranes, tower cranes, and offshore lifting equipment where the hollow center passage accommodates hydraulic lines and electrical cables. The external gear meshes with your drive pinion for precise slewing control.
For excavator swing bearing XOU40/2000 installations, the crossed roller design withstands impact loads during bucket digging cycles while maintaining smooth house rotation. Mining equipment operators value the extended service life in abrasive environments.
Port excavator slewing bearing marine grade applications include ship loaders, unloaders, and container handling cranes where salt spray resistance and continuous operation reliability are essential. Our RoHS-compliant sealing systems exclude contaminants in coastal installations.
The large wind power slewing bearing crossed roller configuration supports yaw and pitch systems in turbines up to 3MW capacity. Stacker reclaimers in bulk material handling facilities use these bearings for boom rotation, while metallurgical plants employ them in ladle turret applications handling molten metal splash.
Manufacturing Capabilities and Customization Services
As a specialized aftermarket 161.40.2000 supplier Luoyang based in China's bearing manufacturing hub, we operate advanced production equipment including CNC vertical lathes for raceway machining, CNC quenching machines for precise heat treatment, and large gear hobbing machines for external tooth cutting.
Our machining centers handle the 42 outer ring bolt holes to ±0.1mm positional tolerance, while coordinate measuring machines verify all critical dimensions. You receive bearings manufactured to your specified precision grade from P0 (standard) through P4 (ultra-precision) depending on your rotational accuracy requirements.
We provide OEM custom gear modifications including different modules, tooth counts, or gear widths to match your existing drive systems.

For replacement projects, we perform old product mapping services when original drawings are unavailable, reverse-engineering your worn bearing to manufacture an exact replacement. This personalized non-standard customization extends to mounting flange modifications, special sealing requirements, or corrosion-resistant coatings for marine environments.
Every 161.40.2000.890.11.1503 bearing undergoes rigorous testing including vibration analysis, raceway runout measurement, and gear tooth contact pattern verification before shipment. Full material traceability documentation accompanies each order for your quality assurance records.
Quality Assurance and Global Compliance
Your large diameter crossed roller slewing bearing 2000mm investment receives comprehensive quality protection through our ISO9001-certified manufacturing processes. From raw material incoming inspection through final assembly, every production stage follows documented procedures with full traceability.
We utilize high-purity bearing steel meeting international standards including DIN 17230 and GB/T 18254 specifications. Ring materials undergo spectral analysis to verify alloy composition, while rollers receive 100% magnetic particle inspection to detect any surface or subsurface defects.
The induction hardening process for raceways is computer-controlled to achieve consistent 55-62 HRC surface hardness with 3-6mm case depth. This hardened layer provides wear resistance while the ductile core absorbs impact loads during operation. Temperature monitoring during quenching ensures proper metallurgical transformation throughout the raceway profile.
Gear tooth profiles are measured with coordinate measuring machines, verifying pitch accuracy, tooth thickness, and lead deviation against ISO 1328 tolerances. For the normalized gear treatment (.890 suffix), we maintain strict temperature control during the normalizing cycle to achieve uniform mechanical properties across the entire gear width.
Our products comply with RoHS directives for restricted substances, supported by material declarations from steel suppliers. Environmental testing validates performance across -40°C to +80°C operating temperatures typical in global deployment regions.
