1205KC3 Bearing Product Overview & Core Advantages
The 1205KC3 is a metric double row angular contact ball bearing engineered for applications requiring high precision and reliable performance. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing delivers exceptional rigidity and can accommodate significant combined radial and axial loads. Its compact design with 15mm width makes it ideal for space-constrained installations while maintaining robust load-carrying capacity. Manufactured with chrome steel rings and balls with a nylon cage, it offers optimized performance for industrial applications demanding precision and durability.
1205KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Impact |
|---|---|---|
| 1205 | Standard bore diameter (25mm) & series designation | Standardized dimensions for interchangeability |
| K | 1:12 Tapered bore | Secure shaft fitting and precise alignment |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-speed applications |
1205KC3 Bearing Structural Features & Performance Benefits
Double Row Design: The two-row ball arrangement provides enhanced stiffness and load capacity, making it suitable for applications with significant combined radial and axial loads.
Tapered Bore Mounting: The 1:12 tapered bore ensures precise interference fit with adapter sleeves, eliminating slippage and maintaining positional accuracy under heavy loads.
Optimized Internal Clearance: The C3 radial clearance accommodates thermal expansion during high-speed operation, preventing premature failure and ensuring stable performance.
Nylon Cage Construction: The lightweight nylon cage reduces friction and enables smooth operation at the limiting speed of 18,000 rpm, while providing excellent corrosion resistance.
Precision Manufacturing: Tight dimensional tolerances on bore diameter (-0.01mm to 0) and outside diameter (-0.013mm to 0) ensure consistent performance and easy installation.
