1309 M Bearing Product Overview & Core Advantages
The 1309 M is a metric double row angular contact ball bearing engineered for exceptional performance in demanding applications. This precision bearing is designed to accommodate combined loads—simultaneously handling significant radial forces and moderate axial loads in both directions. Its double row construction provides high rigidity and stable rotational accuracy, making it ideal for machinery requiring robust support and reliable operation. The open design, combined with a brass cage, facilitates high-speed capability and efficient lubrication.
1309 M Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| M | Brass Cage | Indicates the use of a machined brass cage, which offers excellent strength, low friction, and is suitable for high-speed applications and demanding operating conditions. |
| (No Seal Suffix) | Open (Unsealed) | Designed for applications where external sealing is provided by the housing, allowing for higher speed limits and custom lubrication regimes. |
1309 M Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides a significantly wider load-carrying surface than single row bearings, resulting in superior stiffness and the ability to support substantial radial dynamic loads (8775 lbf) and static loads (3015 lbf).
- Optimized for Combined Loads: The angular contact geometry allows the 1309 M to efficiently manage complex combined radial and axial loads, ensuring stable performance in challenging operational environments.
- High-Speed Performance: The machined brass cage (M) ensures precise guidance of the balls with minimal friction, contributing to a high limiting speed of 8,500 rpm. The open design further enhances heat dissipation.
- Precision & Reliability: Manufactured from chrome steel for both rings and balls, this bearing guarantees high durability and long service life. The standard CN radial internal clearance is suited for a wide range of industrial applications.
1309 M Bearing Typical Application Areas
The 1309 M double row angular contact ball bearing is widely used in machinery and systems that demand high rigidity and precision. Key sectors include:
- Industrial Gearboxes and Transmissions
- Pumps and Compressors
- Material Handling Conveyor Systems
- Agricultural Machinery
