6307-J Bearing Product Overview & Core Advantages
The 6307-J is a single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. This metric bearing is characterized by its ability to handle primarily radial loads and, to a lesser extent, axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable precision for general-purpose use. Its open design allows for versatile lubrication options, while the standard CN radial internal clearance ensures stable operation under normal conditions. The 6307-J is an excellent choice for applications demanding a balance of high load capacity, durability, and cost-effectiveness.
6307-J Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| -J | Indicates a press steel cage (stamped steel cage) positioned by the balls. This design is lightweight and facilitates high-speed operation. |
Base Model (6307): Specifies a single row deep groove ball bearing with a 35 mm bore, 80 mm outside diameter, and 21 mm width.
6307-J Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and robust construction of the 6307-J bearing enable it to support significant radial dynamic load ratings of 7509 lbf and radial static load ratings of 4339 lbf, making it suitable for heavy-duty applications.
- Optimized for Speed: The lightweight and efficient press steel cage (J-suffix) minimizes centrifugal forces, contributing to a limiting speed of 8,500 rpm.
- Material Integrity: All core components—rings, balls, and cage—are manufactured from Chrome Steel, ensuring high hardness, wear resistance, and long service life.
- Versatile Operating Range: With a temperature range of -30°C to 120°C and an open seal type, this bearing can be customized with appropriate lubricants for specific environmental and operational needs.
- Standardized Precision: Conforms to ABEC 1 (ISO P0) tolerance class, providing consistent and reliable dimensional accuracy for smooth operation.
