6306 N Bearing Product Overview & Core Advantages
The 6306 N is a single row deep groove ball bearing designed for exceptional radial load capacity and high-speed operation. This precision bearing features a snap ring groove on its outer ring, enabling secure axial location within a housing without complex machining. Manufactured to P6 tolerance class, it offers superior running accuracy, making it ideal for applications demanding high reliability and rotational precision. Its open design allows for versatile lubrication options to suit specific operational needs.

6306 N Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a stainless steel cage, precision P6 tolerances, and optimized internal geometry enables a high limiting speed of 13,000 rpm, suitable for demanding rotational applications.
- Robust Load Capacity: As a deep groove ball bearing, it is primarily designed to support high radial loads (dynamic: 6654 lbf / static: 3597 lbf), but can also accommodate moderate axial loads in both directions.
- Secure Axial Location: The integrated snap ring groove is a key structural feature that prevents creeping and simplifies the bearing's axial fixation within the housing, enhancing overall system rigidity.
- Versatile Application Range: The open (non-sealed) construction and wide temperature range (-30°C to 120°C) allow for operation in various environments with appropriate lubrication.
6306 N Bearing Typical Application Areas
This bearing is widely used in industries and equipment requiring reliable, high-speed rotation with simple mounting. Key applications include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
