1302J Bearing Product Overview & Core Advantages
The 1302J is a double row angular contact ball bearing designed for applications demanding high precision and reliability. This metric bearing excels in handling combined loads, simultaneously supporting significant radial loads and moderate axial loads in both directions. Its compact double row construction provides enhanced rigidity and load-carrying capacity within a minimal axial space, making it an ideal solution for compact machinery designs requiring robust performance.
1302J Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1302 | Standard bearing series designation, indicating the bearing dimensions (15mm bore, 42mm OD, 13mm width). |
| J | Suffix denoting a specific internal design and steel cage construction, optimized for general performance. |
| Open (Seal Type) | The bearing is supplied without seals or shields, allowing for higher limiting speeds and is typically lubricated for initial operation. |
| CN (Radial Clearance) | Indicates the standard (Normal) radial internal clearance group, suitable for most common operating conditions. |
1302J Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and optimized raceway geometry provide superior stiffness, enabling the bearing to handle higher radial dynamic load ratings (2430 lbf) and resist operational deformations under combined loads.
Optimized for Speed: The pressed steel cage ensures stable ball guidance and low friction, contributing to a high limiting speed of 24,000 rpm, making it suitable for high-speed applications.
Precision & Material Integrity: Manufactured from high-grade chrome steel for both rings and balls, the bearing offers excellent durability and wear resistance. The precise bore diameter tolerance and width tolerance ensure consistent performance and ease of installation in precision assemblies.
1302J Bearing Typical Application Areas
The 1302J bearing is engineered for a wide range of industrial applications, including:
- Electric Motors and Small Gearboxes
- Precision Spindles and Machine Tool Accessories
- Industrial Fans and Blowers
- Material Handling Equipment
- Agricultural Machinery
