1312J Bearing Product Overview & Core Advantages
The 1312J is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing is engineered to accommodate combined loads, simultaneously handling significant radial loads and moderate axial loads in both directions. Its double row design provides high rigidity and stable rotational accuracy, making it ideal for applications requiring high reliability and precise shaft guidance. Manufactured from high-grade chrome steel and supplied pre-lubricated, it offers robust performance and long service life.
1312J Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| 1312 | Standard bore diameter series designation. |
| J | Indicates a specific internal design and CN group radial internal clearance (normal clearance). |
| Open (Seal Type) | No seals or shields, allowing for higher speeds and easier re-lubrication. |
| Lubricated | Factory-filled with high-performance grease for immediate operation. |
1312J Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior high rigidity and stability compared to single row designs. This enables it to support substantial radial dynamic load ratings of 13,162 lbf and handle combined loads effectively.
- Optimized for Speed: The pressed steel cage and open design contribute to a high limiting speed of 6,300 rpm, making it suitable for high-speed applications.
- Precision & Reliability: Manufactured with tight dimensional tolerances on the bore diameter (60 mm) and outside diameter (130 mm), ensuring precise fit and smooth operation. The standard CN radial internal clearance is suited for most common operating conditions.
- Durable Construction: Components made from chrome steel offer high hardness and wear resistance, contributing to a long operational lifespan.
1312J Bearing Typical Application Areas
The 1312J bearing is widely used in various industrial sectors due to its robust design and performance characteristics. Key applications include:
- Industrial Gearboxes and Transmission Systems
- Electric Motors and Generators
- Material Handling Equipment (Conveyors, Pulleys)
- General Industrial Machinery requiring reliable shaft support
