1208-K C/4 Bearing Product Overview & Core Advantages
The 1208-K C/4 is a metric double row angular contact ball bearing engineered for applications requiring high radial load capacity and precise operation. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing delivers exceptional rigidity and stability. Its open design allows for optimal lubrication management, while the nylon cage contributes to smooth, high-speed operation up to 11,000 rpm. This bearing is pre-lubricated and designed to handle significant combined loads, making it an ideal choice for demanding industrial environments where reliability is paramount.
1208-K C/4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1208 | Standard bore diameter (40 mm) and series designation |
| K | Tapered bore with 1:12 ratio |
| C/4 | Specified radial internal clearance group (CN) |
1208-K C/4 Bearing Structural Features & Performance Benefits
Double Row Design: The double row ball complement provides significantly higher radial load capacity and rigidity compared to single row bearings, enabling superior performance under heavy combined loads.
Precision Tapered Bore: The 1:12 tapered bore ensures secure interference fit on tapered shafts, eliminating slippage and maintaining precise alignment under high torque conditions.
High-Speed Capability: The lightweight nylon cage reduces centrifugal forces, while the optimized bearing geometry enables reliable operation at limiting speeds up to 11,000 rpm.
Superior Material Construction: Manufactured from chrome steel for both rings and balls, ensuring high durability, wear resistance, and consistent performance across the operating temperature range of -30°C to 110°C.
