Industrial robot joints demand radical space efficiency. Thin section bearings solve this challenge through a fundamental design advantage: an ultra-low outer-to-inner diameter ratio. With cross-sections just 20% of standard bearings and over 50% weight reduction, they transform joint design. Their constant-section architecture (uniform dimensions across each series) enables flexible sizing without structural changes. Engineers integrate hollow shafts for cabling and piping, maximizing internal space utilization.
Three Critical Application Arenas
1. Precision Joint Systems: The Motion Foundation
Wrist/Elbow Dynamics:
CHGbearing's TypeX series thin-section four-point contact ball bearings handle combined radial/axial loads and overturning moments at P4 (ABEC7) precision. With friction coefficients ≤0.001, they deliver ±0.05mm repeatability in articulated arms.
Rotating Bases:
Millimeter-thin cross roller bearings enable 360° rotation in platforms up to 1500mm diameter. This slashes rotational inertia while maintaining rigidity.
2. Laser Cutting Systems: Conquering Extreme Confinement
CHGbearing's Reali-Slim Series redefines laser head integration:
- Large-bore designs accommodate hollow shafts for integrated pneumatics and wiring
- Dual parallel bearings fit drive systems within 35mm bell housings
- Advanced sealing maintains 0.1mm scanning precision in abrasive cutting environments
3. Reducer Core Technologies: Power Transmission Redefined
Harmonic Reducers:
CHGbearing TypeA series flexible thin-section bearings transmit torque through controlled outer-ring deformation.
RV Reducers:
Angular contact ball bearing stacks achieve unmatched torque density.
Planetary Systems:
Cross roller bearings resist tilt moments in subcompact assemblies.
Humanoid Robotics: The Next Evolution
With 20+ joints per robot, new benchmarks emerge:
- <5g finger joint bearings for dexterous manipulation
- Multi-load hip/knee bearings handling complex dynamic forces
- CHGbearing's humanoid-specific series achieving P2 (ABEC9) precision for rotary/linear systems
The Strategic Advantage
From six-axis arms to humanoid platforms, thin section bearings deliver millimeter-scale thickness with kilonewton-level capacity. As leaders like CHGbearing advance material science and integrated functions (thermal management, IP-rated sealing), these components become pivotal to smart manufacturing sovereignty.
