1315KC3 Bearing Product Overview & Core Advantages
The 1315KC3 is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and superior load capacity. Featuring a tapered bore design (1:12), this precision bearing excels at handling combined radial and axial loads simultaneously. Its optimized internal geometry and C3 radial internal clearance make it particularly suitable for industrial environments where thermal expansion and heavy-duty operation are concerns. Manufactured from premium chrome steel components with a stainless steel cage, it delivers reliable performance across a wide temperature range (-30° to 110°C).
1315KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 1315 | Standard bore diameter (75mm) & series designation | Standardized dimensions for easy integration |
| K | Tapered bore (1:12 ratio) | Facilitates precise mounting and dismounting on tapered shafts |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-speed applications |
1315KC3 Bearing Structural Features & Performance Benefits
Double Row Design: The dual raceway configuration provides significantly higher rigidity compared to single row bearings, making it ideal for applications with moment loads or shaft deflection.
Enhanced Load Capacity: With a radial dynamic load rating of 17,842 lbf and static load rating of 6,750 lbf, this bearing efficiently handles combined loading conditions in demanding environments.
Tapered Bore Advantage: The 1:12 taper enables precise interference fit when mounted with adapter sleeves, ensuring secure shaft positioning and improved rotational accuracy.
Optimized Internal Clearance: The C3 clearance provides adequate internal space to accommodate thermal expansion during high-speed operation, preventing premature failure due to overheating.
Premium Material Construction: Chrome steel rings and balls combined with a stainless steel cage deliver excellent durability and corrosion resistance, supporting a limiting speed of 5,600 rpm.
