1315KJC3 Bearing Product Overview & Core Advantages
The 1315KJC3 is a double row angular contact ball bearing designed for demanding industrial applications requiring high rigidity and reliable performance. This precision bearing features a tapered bore (1:12) for secure shaft mounting and is pre-lubricated for immediate operation. Its double row design enables it to support significant combined loads, including radial forces and axial loads from both directions, making it an ideal solution for compact, high-performance machinery where space and reliability are critical.
1315KJC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1315 | Standard bore diameter (75 mm) and series designation |
| K | Tapered bore with a 1:12 ratio |
| J | Steel cage construction |
| C3 | Greater than normal radial internal clearance for applications with thermal expansion |
1315KJC3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball bearing configuration provides superior stiffness, effectively handling combined loads and moments. With a dynamic load rating of 17,842 lbf and a static load rating of 6,750 lbf, it ensures reliable operation under heavy-duty conditions.
Optimized Internal Geometry: Precision-ground raceways and chrome steel balls minimize friction and wear. The specified C3 radial clearance accommodates shaft expansion in high-temperature applications or interference fits.
Steel Cage & Tapered Bore: The robust steel cage maintains ball alignment at the limiting speed of 5,600 rpm. The tapered bore (1:12) ensures a tight, secure fit on the shaft, enhancing overall system stability.
Pre-Lubricated & Ready-to-Use: Factory-applied lubrication allows for immediate installation and initial operation within the specified temperature range of -30°C to 110°C.
1315KJC3 Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
- Material Handling Equipment such as conveyor pulleys
- Agricultural Machinery including tractor gearboxes
- Pump and Compressor shafts
- Heavy-Duty Industrial Fans and blowers
