Based on bearing size ,bearing can be divided into miniature bearing(D≤26mm),extra small bearing（D=27~55mm）,small size bearing（D=60~115mm）,medium size bearing（D=120~190mm）,large size bearing（D=200~430mm） and extralarge bearing（D≥440mm）.

As the professional large and extra large bearing manufacturer,Luoyang jiayu bearing can design and produce larg and extralarge bearing with OD from 200mm to more than 10m including slewing bearing,crossed roller bearing,thrust bearing and other precision bearings.

Large and extralarge Slewing Bearing

Materials

Rings: 42CrMo, 50Mn, or C45 alloy steel (raceway hardness HRC 55-62 after quenching).

Rollers: GCr15 high-carbon chromium steel (high wear resistance).

Cage: Steel 20 or ZL102 cast aluminum alloy (lightweight and durable).

Spacers: Nylon 6/66 (low friction and thermal stability).

Size Range

External Diameter: 400–12,000 mm (customizable upon request).

Performance

Load Capacity: Axial ≤ 25,000 kN, radial ≤ 15,000 kN, moment ≤ 100,000 kN·m.

Speed Range: Suitable for low to moderate rotational speeds (≤20 rpm).

Description

Design Principles Cross-Roller Arrangement:

Rollers are alternately aligned at 90°, distributing loads evenly. Integrated Raceways: Precision-ground surfaces minimize friction and wear. Modular Design: Supports custom gear configurations (internal/external) and mounting holes. Performance Highlights High Rigidity: Crossed rollers maximize contact area, reducing deformation under load. Ultra-Precise Rotation: Runout tolerance ≤0.005 mm for critical applications. Long Service Life: Advanced heat treatment extends fatigue resistance by 30%.

特点

Multi-load supporting
节省空间
Customizable
Less maintenance

Appliance

Cranes: Port cranes, tower cranes, and mobile crane slewing systems.

Construction Machinery: Shield tunneling machines, excavators, and pile drivers.

Radar & Telescopes: Precision rotation for radar antennas and radio telescopes.

Industrial Equipment: Steel mill rollers, robotic arms, and automated production lines.

Military Systems: Turret rotation mechanisms and missile launch platforms.
