6312-2RS1 Bearing Product Overview & Core Advantages
The 6312-2RS1 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with metric dimensions and manufactured to P6 tolerance class, this bearing delivers high precision and reliable operation. Its key advantage lies in its ability to handle significant radial loads while also accommodating moderate axial loads in both directions. The sealed construction (2RS1) and pre-lubrication ensure long service life and reduced maintenance, making it an ideal choice for applications requiring high reliability and durability.
6312-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6312 | Basic bearing series, indicating a medium duty, single row deep groove ball bearing with a 60mm bore, 130mm OD, and 31mm width. |
| 2RS1 | Contact seals on both sides. The RS1 seal type provides effective protection against contaminants and retains lubricant, contributing to the bearing's maintenance-free characteristics. |
6312-2RS1 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove raceway design is optimized to support high radial dynamic load ratings (19,154 lbf) and radial static load ratings (11,690 lbf). The robust construction ensures stable operation under load.
- Sealed & Pre-Lubricated for Longevity: The 2RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants. Combined with factory-applied grease lubrication, this design offers a sealed-for-life solution, minimizing maintenance needs.
- Precision & Speed Performance: Manufactured to a P6 tolerance class with a standard CN radial internal clearance, this bearing ensures running accuracy and smooth operation. The stainless steel cage and optimized geometry contribute to a reliable limiting speed of 3,400 rpm.
- Durable Material Construction: Components made from chrome steel (rings and balls) and a stainless steel cage provide excellent resistance to wear and corrosion, ensuring a long operational lifespan within a temperature range of -30°C to 120°C.
6312-2RS1 Bearing Typical Application Areas
This versatile bearing is commonly specified in a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring robust and reliable rotary support.
