1315J Bearing Product Overview & Core Advantages
The 1315J metric double row angular contact ball bearing represents a high-performance solution for applications requiring exceptional rigidity and combined load capacity. Engineered with a double row ball construction, this bearing is specifically designed to accommodate significant radial loads simultaneously with axial loads in both directions. Its compact design, featuring a 37 mm width and a 75 mm bore, offers a space-saving profile ideal for precision machinery. Manufactured from chrome steel and supplied lubricated, the 1315J ensures reliable operation and long service life in demanding environments.
1315J Bearing Model Code Explained, Specifications & Naming Convention
The 1315J model designation follows a standard industry coding system. Below is a breakdown of its components:
| Code Segment | Technical Meaning |
|---|---|
| 1315 | Standard bearing series number, defining the core dimensions (75mm bore, 160mm OD, 37mm width). |
| J | Suffix indicating a specific internal design and CN group radial internal clearance, optimized for general operating conditions. |
| Open (Seal Type) | No contact seals, allowing for higher speeds and permitting re-lubrication if required by the application. |
1315J Bearing Structural Features & Performance Benefits
The design of the 1315J bearing translates directly into key performance advantages for engineers:
- High Rigidity: The double row angular contact design provides superior stiffness compared to single row bearings, minimizing shaft deflection under heavy combined loads.
- Superior Load Capacity: With a dynamic load rating of 17,842 lbf and a static load rating of 6,750 lbf, this bearing is built to handle demanding radial and bidirectional axial forces.
- Optimized for Performance: The pressed steel cage ensures stable operation at the limiting speed of 5,600 rpm. The standard CN radial internal clearance is suited for a wide range of common applications.
- Material Integrity: Components made from chrome steel offer high load capacity and durability, contributing to the bearing's reliable performance across a temperature range of -30°C to 110°C.
1315J Bearing Typical Application Areas
The 1315J double row angular contact ball bearing is ideally suited for a variety of industrial applications where high rigidity and reliability are paramount. Key sectors include:
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Medium-duty Machine Tool Spindles
