1307 M Bearing Product Overview & Core Advantages
The 1307 M is a metric double row angular contact ball bearing designed for applications requiring high rigidity and the ability to handle combined loads. Its open construction allows for versatile lubrication options, while the brass cage ensures stable operation at high rotational speeds. This bearing is engineered to provide reliable performance in demanding environments, offering a balance of high load capacity and precision.
1307 M Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1307 | Basic bearing designation indicating the bearing size (35mm bore, 80mm OD, 21mm width). |
| M | Signifies the use of brass (copper alloy) cage, which provides excellent strength and is suitable for high-speed applications. |
1307 M Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized internal geometry enable the bearing to support significant radial loads and moderate axial loads in both directions, providing stable and rigid shaft support.
- High-Speed Performance: The machined brass cage (M) ensures low friction, excellent guidance, and dimensional stability, contributing to a high limiting speed of 11,000 rpm.
- Precision & Reliability: Manufactured from chrome steel for both rings and balls, the bearing offers high durability and wear resistance. The standard CN radial internal clearance is suitable for most general applications.
- Versatile Lubrication: The open seal type allows for the application of various greases or oil lubrication systems, enabling optimization based on specific operational temperature ranges and conditions.
1307 M Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
