1307 KC3 Bearing Product Overview & Core Advantages
The 1307 KC3 is a metric double row angular contact ball bearing engineered for applications requiring high radial load capacity and precision performance. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing delivers exceptional rigidity and stability in compact designs. Its C3 radial internal clearance accommodates thermal expansion in demanding operating conditions, while the nylon cage ensures smooth operation at high speeds. Pre-lubricated for immediate use, this bearing offers reliable performance across a wide temperature range from -30°C to 110°C.
1307 KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 1307 | Basic bearing designation (35mm bore, 80mm OD) | Standard metric dimensions for easy integration |
| K | 1:12 Tapered bore | Secure mounting and precise positioning on tapered shafts |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-speed applications |
1307 KC3 Bearing Structural Features & Performance Benefits
Double Row Design: The dual ball complement provides enhanced radial load capacity and superior rigidity compared to single row bearings, making it ideal for applications requiring stable rotational accuracy.
Tapered Bore Configuration: The 1:12 tapered bore ensures precise interference fit when mounted with adapter sleeves, eliminating slippage and maintaining positional accuracy under heavy loads.
High-Speed Capability: The nylon cage minimizes friction and allows for limiting speeds up to 11,000 rpm, while the C3 clearance prevents thermal binding during high-speed operation.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, this bearing delivers excellent wear resistance and durability in demanding industrial environments.
