307SW1 Bearing Product Overview & Core Advantages
The 307SW1 is a high-performance single row deep groove ball bearing designed for reliable operation in a wide range of industrial applications. Engineered from chrome steel, this bearing is characterized by its ability to handle significant radial loads and moderate axial loads in both directions. Its open design allows for versatile lubrication options, while its CN radial internal clearance and ABEC 1 (ISO P0) tolerance class ensure consistent performance and smooth operation, making it a robust and cost-effective solution for general machinery.
Model Code Breakdown
- 307SW1: Basic bearing designation indicating the size series and bore diameter.
- Seal Type: Open - No integral seals or shields, allowing for high-speed operation and custom lubrication.
- Tolerance Class: ABEC 1 | ISO P0 - Standard precision grade for general industrial use.
- Radial Internal Clearance: CN - Normal clearance group, suitable for most operating conditions.
- Lubrication: None - Bearing is supplied without grease, providing flexibility for the user to apply the optimal lubricant for the specific application.
307SW1 Bearing Structural Features & Performance Benefits
The 307SW1's performance stems from its fundamental deep groove ball bearing construction. The single row of balls within deep, uninterrupted raceways provides excellent radial load capacity and accommodates combined loads. The use of high-grade chrome steel for all critical components (rings, balls, cage) ensures high durability and a long service life. The open design is key to achieving a high limiting speed of 9,500 rpm, as it minimizes friction and heat generation. The standardized bearing dimensions (35mm bore, 80mm OD, 21mm width) and tight dimensional tolerances guarantee easy integration and reliable performance.
307SW1 Bearing Typical Application Areas
This versatile bearing is widely used across various industries due to its robust design and reliable performance. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment
- Agricultural Machinery
- Pumps and Fans
