1301J Bearing Product Overview & Core Advantages
The 1301J double row angular contact ball bearing is a precision bearing engineered for applications requiring high rigidity and reliable performance under combined loading conditions. Its compact double row design enables it to support significant radial loads and bidirectional axial loads simultaneously, making it an ideal choice for high-precision machinery. Manufactured from high-grade chrome steel and featuring a steel cage, this bearing delivers exceptional durability and operational stability.
1301J Bearing Model Code Explained, Specifications & Naming Convention
The 1301J model number follows a standard industry designation. A breakdown of its components is provided below:
- 1301: Indicates the basic bearing series, defining the boundary dimensions (12mm bore, 37mm OD, 12mm width).
- J: Signifies a specific internal design and radial internal clearance of CN (Normal Group).
1301J Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior rigidity and enables the bearing to handle substantial combined loads (radial and axial) from both directions, ensuring stable shaft support.
- Optimized for Performance: The pressed steel cage ensures smooth operation at high speeds, contributing to the bearing's limiting speed of 28,000 rpm. The standard CN radial internal clearance is suited for a wide range of common operating conditions.
- Precision Engineering: Manufactured with tight dimensional tolerances on the bore, outside diameter, and width, this bearing guarantees precise fit and consistent performance in demanding applications.
- Material Integrity: Constructed from chrome steel for both rings and balls, the bearing offers high wear resistance and a long operational lifespan.
1301J Bearing Typical Application Areas
This versatile double row angular contact ball bearing is commonly specified in:
- Electric Motors and Generators
- Precision Gearboxes
- Industrial Pumps and Compressors
- Machine Tool Spindles and Auxiliary Units
- Material Handling Equipment
