308SZZG Bearing Product Overview & Core Advantages
The 308SZZG is a single row deep groove ball bearing designed for robust performance in demanding applications. Engineered with metric dimensions and manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers reliable operation and high radial load capacity. Its key advantages include a shielded design for contaminant protection, a wide operating temperature range from -30°C to 120°C, and compliance with ROHS and REACH environmental standards, making it suitable for various industrial applications requiring consistent performance and durability.
308SZZG Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| S | Indicates a bearing with a snap ring groove on the outer ring for secure axial positioning. |
| ZZ | Signifies double-shielded construction (one shield on each side) providing effective protection against solid contaminants while allowing for high-speed operation. |
| G | Denotes the use of a stamped steel cage, offering a good balance of strength, speed capability, and cost-effectiveness. |
308SZZG Bearing Structural Features & Performance Benefits
- Optimized Load Handling: The single row deep groove raceway geometry is precision-engineered to support high radial dynamic load ratings (10,274 lbf) and radial static load ratings (8,093 lbf), ensuring reliable performance under significant stress.
- Contaminant Exclusion: The double-shielded (ZZ) design effectively seals the bearing interior from dust and debris, extending service life and maintaining performance in less-than-ideal environments without the added friction of contact seals.
- High-Speed Capability: The combination of the stamped steel cage (G) and the low-friction shield design contributes to a high limiting speed of 8,500 rpm, suitable for a wide range of high-velocity applications.
- Precision & Stability: Manufactured to ABEC 1 precision standards with a standard CN radial internal clearance, this bearing provides consistent running accuracy and smooth operation, minimizing vibration and noise.
308SZZG Bearing Typical Application Areas
The 308SZZG is ideally suited for applications requiring a reliable, shielded, and high-speed deep groove ball bearing. Common uses include:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor systems)
- Agricultural Machinery
- Various Automotive Components
