Product Description

Custom High Precision Bearing with Crossed Roller Bearing Made in China Rks.160.14.0644
 

Product Description

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.

1. Crossed Roller Design

• 90° alternately arranged rollers provide simultaneous support for radial, axial, and moment loads

• High rigidity with minimal elastic deformation under load

• Low friction due to optimized roller alignment and precision grinding

2. High-Precision Manufacturing

• Grinding & superfinishing (Ra ≤ 0.05 µm) for smooth motion

• Tight tolerances: ABEC 3/5 (P4/P2) standard, higher grades available

• Preload options for applications requiring zero backlash

3. Robust Material & Construction

• High-carbon chromium steel (100Cr6) with through-hardening (60-64 HRC)

• Optional corrosion-resistant treatments (e.g., black oxide, Dacromet)

• Integral mounting surfaces for simplified installation

 

Performance Advantages

1. Exceptional Load Capacity

• 50% higher moment stiffness vs. standard ball bearings

• Uniform load distribution across rollers, reducing stress concentrations

2. Space-Saving Design

• Single-bearing solution eliminates need for multiple bearing arrangements

• Compact cross-section for applications with envelope constraints

3. Maintenance Efficiency

• Long relubrication intervals due to optimized internal geometry

• Sealed variants available for contaminated environments
