1306J Bearing Product Overview & Core Advantages
The 1306J is a metric double row angular contact ball bearing engineered for applications demanding high precision and reliability. Its double row design provides superior rigidity and the capacity to support combined loads—significant radial loads with moderate axial loads in both directions. Featuring an open construction and precision-ground chrome steel components, this bearing is optimized for smooth operation and long service life in high-performance machinery. Its compact dimensions and high limiting speed make it an ideal choice for space-constrained, high-speed applications.
1306J Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1306 | Basic bearing designation indicating a metric double row angular contact ball bearing with a 30mm bore diameter. |
| J | Specifies a CN group radial internal clearance, which is the standard (normal) clearance for general applications. |
1306J Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides a rigid support system, enabling the bearing to handle substantial radial dynamic loads (5062 lbf) and static loads (1530 lbf), as well as bidirectional axial loads.
- Optimized for High-Speed Operation: The pressed steel cage and precision engineering contribute to a high limiting speed of 13,000 rpm, ensuring stable performance in demanding rotational applications.
- Precision & Durability: Manufactured from high-grade chrome steel for both rings and balls, the bearing offers excellent wear resistance and dimensional stability. The open seal type allows for easy re-lubrication and is suitable for environments where seals are managed externally.
- Standard Internal Clearance: The CN clearance is ideal for most operating conditions, providing a balance between fit, temperature, and load requirements.
1306J Bearing Typical Application Areas
This double row angular contact ball bearing is widely used in various industrial sectors, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
