1306-K C/2 Bearing Product Overview & Core Advantages
The 1306-K C/2 is a metric double row angular contact ball bearing designed for applications requiring high precision and robust performance. Its double row construction provides superior rigidity and enables it to accommodate combined loads—significant radial loads and moderate axial loads in both directions. Featuring a tapered bore (1:12) and an open design, this bearing is engineered for precise mounting and high-speed operation, making it an ideal choice for demanding industrial environments where reliability is critical.
1306-K C/2 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1306 | Standard bearing series designation, indicating the bearing dimensions (30mm bore, 72mm OD). |
| K | Denotes a tapered bore with a 1:12 ratio, facilitating precise interference fits on adapter sleeves or withdrawal sleeves. |
| C/2 | Specifies the radial internal clearance group. C/2 corresponds to a CN clearance (Normal Group), which is standard for most general applications. |
1306-K C/2 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides excellent stiffness, enabling stable operation under combined radial and axial loads. With a dynamic load rating of 5062 lbf and a static load rating of 1530 lbf, it offers reliable performance in high-stress conditions.
- Precision Tapered Bore: The 1:12 tapered bore ensures a secure, concentric fit when mounted with appropriate sleeves, minimizing slippage and maintaining alignment for high-speed applications.
- Optimized High-Speed Performance: The nylon cage reduces friction and weight, contributing to a high limiting speed of 13,000 rpm. The open seal type allows for efficient lubrication management.
- Superior Material & Lubrication: Constructed from chrome steel for both rings and balls, ensuring high durability and wear resistance. The bearing is pre-lubricated and operates effectively within a temperature range of -30°C to 110°C.
1306-K C/2 Bearing Typical Application Areas
