305-Z Bearing Product Overview & Core Advantages
The 305-Z is a single row deep groove ball bearing designed for reliable performance in various industrial applications. This shielded bearing offers excellent capability for handling radial loads and moderate axial loads in both directions. Its compact design, featuring a 25 mm bore and 62 mm outside diameter, makes it suitable for applications where space is limited. Manufactured with precision tolerances and pre-lubricated with grease, the 305-Z delivers consistent operation, long service life, and requires minimal maintenance, making it an ideal choice for high-reliability scenarios.
305-Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 305 | Standard bearing series designation, indicating core dimensions (25mm bore, 62mm OD, 17mm width). | Ensures dimensional interchangeability and easy sourcing. |
| Z | One side shielded (non-contact metal shield). | Provides effective contamination protection while maintaining high-speed capability and low friction. |
305-Z Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built with chrome steel rings and balls, this bearing achieves a high dynamic load rating of 5148 lbf and a static load rating of 3507 lbf, ensuring durability under significant radial stresses.
- Optimized High-Speed Performance: The combination of a lightweight nylon cage and effective grease lubrication enables a limiting speed of 13,000 rpm, making it suitable for high-velocity applications.
- Precision & Reliability: Manufactured to P0 tolerance class with a standard (CN) radial internal clearance, it guarantees smooth, precise, and low-vibration operation.
- Low Maintenance & Extended Service Life: The integral Z-shield retains the factory-applied grease, effectively excluding contaminants and extending lubrication intervals, promoting a long, maintenance-free operational life.
