1213-K P/6 C/3 Bearing Product Overview & Core Advantages
The 1213-K P/6 C/3 is a metric double row angular contact ball bearing engineered for high-performance applications requiring superior rigidity and precise operation. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing is designed to accommodate significant combined radial and axial loads simultaneously. Its open construction allows for versatile lubrication options, making it an ideal choice for demanding industrial environments where precision and reliability are paramount. The optimized internal geometry and high-quality materials contribute to its excellent load-carrying capacity and operational stability.
Model Code Breakdown
- 1213: Basic bearing series, indicating a double row angular contact design with specific dimensions.
- K: Denotes a tapered bore with a 1:12 ratio.
- P/6: Specifies a CN radial internal clearance group, which is the standard/normal clearance for general applications.
- C/3: Indicates that the bearing is lubricated with a specific grease suitable for the defined operating conditions.
1213-K P/6 C/3 Bearing Structural Features & Performance Benefits
The double row ball bearing construction provides significantly higher rigidity and moment load capacity compared to single row designs, making it exceptionally stable under combined loading conditions. The tapered bore ensures a precise and secure interference fit on the shaft, eliminating slippage and maintaining concentricity. The nylon cage offers low friction and is ideal for high-speed operation, contributing to the bearing's impressive limiting speed. Manufactured from chrome steel for both rings and balls, the bearing delivers high durability and a long service life. The standard CN radial internal clearance is optimized for a wide range of operating conditions, providing a balance between temperature management and running precision.
