| 308 | Standard Bore Size | Denotes a 40 mm bore diameter and standard boundary dimensions. |
| S | Shielded (Single Side) | Indicates the bearing is equipped with a metal shield on one side. |
| ZZ | Shielded (Both Sides) | Confirms the bearing features shielded seals on both sides, offering superior contamination protection. |
308SZZ Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built entirely from chrome steel for rings, balls, and cage, this bearing delivers high strength and durability. It boasts a dynamic load rating of 10,274 lbf and a static load rating of 8,093 lbf, ensuring reliable performance under significant radial loads.
- Optimized for High-Speed Operation: The precision-ground components and stable cage design contribute to a high limiting speed, enabling smooth operation at up to 8,500 rpm.
- Effective Sealing & Maintenance Simplicity: The non-contact ZZ shields effectively prevent the entry of solid contaminants while minimizing friction, allowing for high-speed capability. The bearing is supplied without lubrication, providing flexibility for the user to apply a grease suitable for the specific application environment.
- Precision & Reliability: Manufactured to ABEC 1 precision class with a standard CN radial internal clearance, it guarantees consistent running accuracy and low vibration, which is critical for the smooth operation of industrial equipment.
