Thin-Section Four-Point Contact Ball Bearings: Core Solution for Lightweight Precision Transmission

Thin-Section Four-Point Contact Ball Bearings:Core Advantages

Bidirectional High Load Capacity: A single bearing simultaneously handles bidirectional axial, radial loads, and overturning moments, simplifying equipment structure.

Ultra-Thin & Lightweight: Wall thickness reduced by 30%-50%, significantly saving space. Ideal for compact applications like robotic joints and medical devices.

High Precision & Low Noise: Accuracy up to P4/P5 grade. Low-friction design ensures smooth high-speed operation.

Flexible Installation: Options include outer ring with mounting holes (direct bolting) or solid-ring design, improving assembly efficiency.

Typical Applications

Industrial robot joints, medical CT scanner supports, precision rotary tables, radar antennas, and service robot chassis—meeting demands for high rigidity, micron-grade accuracy, and lightweight performance.

Key Selection Criteria

Dimensions: Precisely measure bore diameter (d), outer diameter (D), and width (B).

Loads: Verify bidirectional axial force, radial force, and overturning moment.

Precision: Opt for P4 grade for high-precision scenarios; P5 grade for general use.

Environment: Use stainless steel in corrosive settings; copper-alloy cages for high-speed applications.

Installation: Prioritize outer-ring-with-holes models (e.g., K-Series) to eliminate bearing housings.
