1303 P/6 C/2 Bearing Product Overview & Core Advantages
The 1303 P/6 C/2 is a Double Row Angular Contact Ball Bearing designed for applications requiring high rigidity and precision. This metric bearing features an open design and is engineered to accommodate significant combined loads, including radial and axial forces in both directions. Its compact dimensions (17mm bore, 47mm OD, 14mm width) and robust construction with a brass cage make it an ideal choice for high-reliability machinery where space is constrained and performance is critical.
1303 P/6 C/2 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| 1303 | Basic bearing designation, indicating the series and size. |
| P/6 | Specifies the tolerance class (P6), indicating higher than normal running accuracy and dimensional precision. |
| C/2 | Indicates the radial internal clearance group (C2), which is smaller than the standard CN group, suitable for applications requiring precise shaft positioning and minimal play. |
1303 P/6 C/2 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior rigidity and enables the bearing to support substantial combined radial and axial loads simultaneously, making it suitable for complex loading conditions.
- Precision Performance: The P6 tolerance class ensures high dimensional and running accuracy, contributing to smooth operation and reduced vibration in precision assemblies.
- Optimized Internal Clearance: The specified C2 radial internal clearance is ideal for applications with precise fits, high rotational accuracy requirements, and controlled thermal expansion.
- Durable Construction: Components made from chrome steel and a robust brass cage offer excellent durability and reliable performance under demanding operating conditions.
- Lubrication & Speed: The bearing comes lubricated and is capable of operating at a limiting speed of 20,000 rpm, suitable for many high-speed applications.
1303 P/6 C/2 Bearing Typical Application Areas
This bearing is commonly specified in:
- Precision Spindles for machine tools and grinding applications
- High-speed Electric Motors and Pumps
- Gearboxes and transmission systems
- Precision industrial machinery requiring high rigidity and accuracy
