6210-2Z Deep Groove Ball Bearing with Seals/Shields: Precision Engineering for Demanding Applications
Overview
The 6210-2Z deep groove ball bearing represents a sophisticated solution for modern mechanical systems requiring reliable rotational performance under diverse loading conditions. Engineered with integral sealing technology, this bearing combines advanced friction management with robust contamination protection, making it ideal for applications where maintenance access is limited or operating environments are challenging.
Key Technical Features
Advanced Sealing System
- Dual Shield (2Z) Design: Non-contact 95%+ particulate ingress while maintaining <0.3 N·m starting torque
- Lubrication Retention: Specialized sealing geometry retains 98% of initial grease volume over standard bearing service intervals
- IP54 Equivalent Protection: Meets international standards for dust and splash resistance without compromising rotational efficiency
Optimized Design
- Single-Row Raceway Geometry: Precision-ground grooves with 15° contact angle accommodate:
- Radial loads up to 32.5 kN static / 19.8 kN dynamic
- Axial loads up to 18% of radial capacity in both directions
- Low-Profile Cross Section: 20mm width design enables installation in space-constrained housings without sacrificing load capacity
- Ultra-Smooth Operation: Surface finish ≤0.05μm Ra reduces vibration to <1.8 mm/s RMS at 6,000 RPM
- High-Speed Capability: DG grease formulation permits continuous operation at 10,000 RPM (oil lubrication extends to 15,000 RPM)
- Temperature Resilience: -30°C to +120°C operational range with standard greases (special formulations available to +200°C)
