• Operating Temperature Range: -30°C to +120°C (standard)

 

Key Features

1. Optimized Raceway Geometry

• Four-point contact design for simultaneous axial, radial, and moment load support

• 35° contact angle for balanced load distribution

• Crowned raceways to minimize edge stress and prolong fatigue life

2. High-Precision Manufacturing

• Grinding & superfinishing (Ra ≤ 0.1 µm) for smooth operation

• Tight tolerances (ISO P0 standard, ABEC 3/5 optional)

• Preload-adjustable variants for applications requiring high rigidity

3. Material & Surface Treatment

• High-carbon chromium steel (100Cr6) for core strength

• Case hardening (58-62 HRC) for wear resistance

• Optional corrosion-resistant coatings (e.g., Zn-Ni, Dacromet)

 

Performance Advantages

1. High Load Capacity in Compact Design

• 40% higher axial load rating vs. standard ball bearings

• Reduced system weight by eliminating separate thrust bearings

2. Low Friction & Energy Efficiency

• Friction coefficient (μ) < 0.003 under optimal lubrication

• Reduced heat generation, enabling higher speed capability

3. Long Service Life & Reliability

• L10 life > 100,000 hours under normal operating conditions

• Consistent performance with minimal maintenance requirements

 

Configuration Options

• Sealing Solutions:

  • Triple-lip seals (contact type)

  • Labyrinth seals (non-contact, low friction)

• Lubrication Methods:

  • Grease-packed (standard)

  • Oil lubrication (high-speed variants)

  • Re-lubrication ports (for extended service intervals)

• Mounting Arrangements:

  • Bolt holes (standard)

  • Custom flange designs available

 

Typical Applications

• Industrial Machinery: Rotary tables, indexing heads

• Material Handling: Crane slewing rings, robotic arms

• Energy Sector: Wind turbine pitch bearings

• Precision Equipment: Medical imaging devices, telescope mounts

 

Technical Support & Documentation

• Available Data:

  • Dynamic & static load ratings

  • Stiffness calculations

  • Fatigue life estimations

  • Mounting and maintenance guidelines

Related Slewing Bearing

Single row cross roller slewing bearing
Composed of two or three rings. compact structure, light weight, high manufacturing accuracy, small assembly gap and high requirement for installation accuracy. Rollers are 1:1 cross-arranged.
Can be bear axial force, overturning moment and large radial force at the same time,and widely used in lifting transportation, construction machinery and precesion products.

Double row ball slewing bearings
This kind of bearings can support high static loads with simple structures. They are mainly used in situations with variation load position and direction and continuously rotating. Main applications of this kind of bearings are deck hoisting, mining and material handling etc.

Three row roller slewing bearing
Three row roller bearing able to bear all kinds of loads at the same time, it is the largest one of the four structural products with large axle and radial dimensions and firm structure. Especially suitable for heavy machinery requiring larger diameter, such as bucket wheel stacker and reclaimer, wheel crane, marine crane, port crane, ladle turret,large tonnage truck crane,heavy machinery and so on.
