308S Bearing Product Overview & Core Advantages
The 308S is a single row deep groove ball bearing designed for exceptional radial load capacity and high-speed operation. Engineered with precision tolerances (ABEC 1 | ISO P0), it delivers reliable performance in demanding applications. Its open design facilitates direct lubrication and allows for versatile mounting configurations. Constructed entirely from high-grade chrome steel, this bearing offers excellent durability and a long service life, making it an ideal choice for general industrial machinery requiring robust and efficient bearing performance.
308S Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| 308 | Basic Bearing Number | Defines the standard bearing dimensions: 40mm bore, 90mm OD, 23mm width. |
| S | Ring Material & Design | Indicates bearings rings and rolling elements are made from chrome steel. |
Note: The absence of seals (Open) or specific cage designations in the model code signifies a standard, versatile configuration.
308S Bearing Structural Features & Performance Benefits
- Optimized Radial Load Capacity: The single row deep groove raceway geometry is precision-engineered to handle high radial dynamic loads (10,274 lbf) efficiently, providing stable and reliable support for rotating shafts.
- High-Speed Capability: With a limiting speed of 8,500 rpm, this bearing is suitable for high-velocity applications. The standard chrome steel cage ensures stability and integrity at elevated rotational speeds.
- Precision & Consistency: Manufactured to ABEC 1 (ISO P0) tolerance class with a standard radial internal clearance (CN), this bearing guarantees smooth operation, low vibration, and consistent performance.
- Versatile Lubrication: The open seal type allows for easy application of various greases or oils, enabling customization of lubrication based on specific operational speed and temperature requirements.
308S Bearing Typical Application Areas
The 308S deep groove ball bearing is widely used across numerous industries due to its robust design and reliable performance. Key applications include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring high-speed and radial load support
