609-2Z Bearing Product Overview & Core Advantages
The 609-2Z is a single row deep groove ball bearing designed for high-performance applications requiring reliable operation under radial loads. Featuring shielded construction on both sides, this precision bearing offers excellent protection against contamination while maintaining optimal performance. With its compact dimensions (9mm bore, 24mm OD, 7mm width) and P6 tolerance class, it delivers exceptional running accuracy and rotational stability. The bearing comes pre-lubricated with high-quality grease, making it ready for immediate installation and ensuring long-term, maintenance-free operation across a wide temperature range from -30°C to 120°C.
609-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 609 | Basic designation for single row deep groove ball bearing series with 9mm bore diameter | Standardized dimensions for easy interchangeability |
| 2Z | Double-sided steel shields (non-contact type) | Effective contamination protection while maintaining high-speed capability |
609-2Z Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The deep groove raceway geometry enables efficient handling of radial loads (877 lbf dynamic, 373 lbf static) while accommodating moderate axial loads in both directions.
Enhanced Durability: Constructed from chrome steel rings and balls with stainless steel cage, the bearing delivers superior wear resistance and corrosion protection, ensuring extended service life.
High-Speed Performance: With a limiting speed of 34,000 rpm and CN radial clearance, the bearing maintains stable operation at high rotational speeds while minimizing friction and heat generation.
Maintenance-Free Operation: The combination of double shields and factory-applied grease lubrication creates a sealed environment that prevents lubricant leakage and contaminant ingress, enabling long-term operation without re-lubrication.
Precision Engineering: Manufactured to P6 tolerance class with tight dimensional control (bore: -0.007mm to 0, OD: -0.008mm to 0), ensuring consistent performance and smooth operation in precision applications.
