6312/C4H Bearing Product Overview & Core Advantages
The 6312/C4H is a single row deep groove ball bearing engineered for high-performance industrial applications requiring exceptional radial load capacity and operational precision. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers reliable performance and dimensional consistency. Its defining feature is the C4 radial internal clearance, which is greater than normal, making it particularly suitable for applications involving thermal expansion, heavy loads, or where interference fits are used. The open design allows for versatile lubrication options, enabling optimal performance across its wide operating temperature range.
6312/C4H Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6312 | Basic bearing designation: Metric series, 60mm bore, 130mm OD, 31mm width. |
| /C4 | Specifies a radial internal clearance greater than Normal (C0). This is critical for accommodating thermal expansion and heavy interference fits. |
| H | Indicates the bearing is manufactured from hardened steel, ensuring high durability and resistance to deformation under load. |
6312/C4H Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove construction and hardened chrome steel components provide a high radial dynamic load rating of 18,412 lbf and a static load rating of 11,735 lbf, making it robust for demanding applications.
- Optimized Internal Clearance: The C4 clearance is a key performance feature. It prevents pre-loading and potential seizure in applications prone to shaft and housing thermal expansion or where press fits are utilized.
- Precision & Stability: Built to ABEC 1 (ISO P0) tolerance class, this bearing ensures smooth, low-vibration operation and consistent running accuracy, contributing to the longevity of the entire assembly.
- Versatile Application Range: The open seal type and wide temperature range (-30°C to 120°C) allow it to be used with various lubricants in diverse environmental conditions.
