This 6706ZZ thin-section deep groove ball bearing is precision-engineered for high-performance robotic and automation applications. Manufactured in China’s leading bearing hub using premium GCr15 steel, it meets ISO and CE standards for reliability and consistency.
Key Performance Features:
- High Precision & Low Friction: Achieves tight tolerances (0.001–0.002 mm) with ultra-fine grinding and optimal clearance. Friction coefficient as low as μ ≤ 0.0012 for smooth, efficient operation.
- Compact & Lightweight: Ultra-thin 4mm width with 30mm bore and 37mm outer diameter, ideal for space-constrained robotic joints and arms.
- Durability: Hardened to HRC60 ± 2 for excellent load capacity and impact resistance. ZZ metal shields provide effective dust protection.
- Low Noise: Precision polishing delivers quiet operation (≤ 20 dB).
- Temperature Range: Stable performance from -40°C to 150°C.
Applications: Perfect for collaborative robots, robotic arms, harmonic reducers, CNC machines, and precision automation systems.
Widely trusted as a high-cost-performance alternative to imported bearings. Available for immediate shipment with OEM customization support.
