305SW1 Bearing Product Overview & Core Advantages
The 305SW1 is a single row deep groove ball bearing engineered for high-performance radial load applications. Characterized by its open design and manufactured to ABEC 1 (ISO P0) precision standards, this bearing offers reliable operation and excellent value. Its chrome steel construction for rings, balls, and cage ensures durability and consistent performance under demanding conditions. The 305SW1 is designed for applications requiring a robust solution for pure radial loads, providing a long service life and stable operation across a wide temperature range.

| Model Segment | Technical Meaning |
|---|---|
| 305 | Standard bearing series designation, indicating the basic dimensions (Bore: 25mm, OD: 62mm, Width: 17mm). |
| S | Indicates a standard radial internal clearance group (CN). |
| W1 | Signifies the use of a chrome steel cage. |
| (No Seal Suffix) | The bearing is open, allowing for high-speed operation and custom lubrication strategies. |
305SW1 Bearing Structural Features & Performance Benefits
Optimized for Radial Loads: The single row deep groove geometry is specifically designed to handle significant radial dynamic load ratings (5148 lbf), making it a workhorse for radial force transmission.
High-Speed Capability: The open seal type and robust chrome steel cage contribute to a high limiting speed of 13,000 rpm, minimizing friction and heat generation.
Precision and Stability: Manufactured to ABEC 1 precision with tight dimensional tolerances, this bearing ensures smooth running and accurate shaft positioning, reducing vibration and noise.
Robust Construction: The all-chrome steel construction (rings, balls, cage) provides high hardness, wear resistance, and a long operational lifespan.
305SW1 Bearing Typical Application Areas
The 305SW1 ball bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring reliable radial load support
