6312-2RSH Bearing Product Overview & Core Advantages
The 6312-2RSH is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This sealed bearing excels at handling high radial loads while also accommodating moderate axial loads in both directions. Its metric dimensions (60mm bore, 130mm OD, 31mm width) and P6 tolerance class ensure high precision and reliable operation. Pre-lubricated with grease and featuring robust sealing, the 6312-2RSH offers a maintenance-free solution for applications requiring long service life and consistent performance across a wide temperature range from -30°C to 120°C.
6312-2RSH Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 63 | Medium duty series | Optimized balance between load capacity and size |
| 12 | Bore diameter code (60mm) | Standard metric sizing for shaft compatibility |
| 2RSH | Double contact seals (NBR rubber) | Superior contamination protection and grease retention |
6312-2RSH Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and chrome steel construction provide a dynamic load rating of 19,154 lbf and static load rating of 11,690 lbf, enabling reliable operation under significant radial stresses.
- Precision Performance: Manufactured to P6 tolerance class with CN radial clearance, ensuring smooth operation, reduced vibration, and precise rotational accuracy for demanding applications.
- Maintenance-Free Operation: The 2RSH double seals effectively exclude contaminants while retaining grease, combined with stainless steel cage for corrosion resistance, delivering extended service life without relubrication.
- Optimized Speed Capability: The precision-ground components and grease lubrication enable a limiting speed of 3,400 rpm, making it suitable for various industrial speed requirements.
6312-2RSH Bearing Typical Application Areas
- Electric Motors and Gearboxes where reliable radial load support is critical
- Industrial Pumps and Compressors requiring sealed bearing solutions
- Material Handling Equipment such as conveyor systems and pulley assemblies
- Agricultural Machinery and Construction Equipment operating in demanding environments
- General Industrial Machinery where maintenance-free operation and long service life are priorities
