6312-2RS1/C3 Bearing Product Overview & Core Advantages
The 6312-2RS1/C3 is a sealed single row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing is characterized by its ability to handle significant radial loads and moderate axial loads in both directions. Its C3 radial internal clearance makes it particularly suitable for applications involving thermal expansion or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable operation and is pre-lubricated and sealed for long service life, making it a versatile and maintenance-friendly solution.
6312-2RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 6312 | Basic Bearing Number | Denotes a single row deep groove ball bearing with a 60 mm bore, 130 mm OD, and 31 mm width. |
| -2RS1 | Sealing Type | Features contact rubber seals on both sides. The "RS1" suffix indicates Nitrile Rubber (NBR) seals, providing excellent protection against contaminants and retaining lubricant effectively. |
| /C3 | Radial Internal Clearance | Specifies a greater than normal (C3) radial internal clearance. This is crucial for applications with shaft misalignment, thermal expansion, or heavy interference fits, preventing premature bearing failure due to excessive preload. |
6312-2RS1/C3 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing ensures high strength and durability. With a dynamic load rating of 18,412 lbf and a static load rating of 11,735 lbf, it is engineered to handle substantial radial loads and combined loads reliably.
- Effective Sealing & Pre-Lubrication: The integral 2RS1 rubber seals provide a high degree of protection against dust, moisture, and other contaminants. The bearing comes pre-lubricated, offering a maintenance-free solution for the majority of its service life within its specified operating range.
- Optimized for Challenging Conditions: The C3 internal clearance is a key feature that accommodates dimensional changes from heat generation or press fits, ensuring stable performance and reducing the risk of seizure under such conditions.
- Standard Precision & Speed: Conforming to ABEC 1 (ISO P0) tolerance class, it provides consistent and reliable operation for general industrial applications, with a limiting speed of 5,300 rpm.
6312-2RS1/C3 Bearing Typical Application Areas
- Electric Motors: A standard choice for motor bearings in industrial fans, pumps, and compressors.
- Industrial Gearboxes: Used in various power transmission systems requiring reliable radial load support.
- Material Handling Equipment: Ideal for conveyor pulleys, rollers, and other machinery in harsh environments.
- Agricultural Machinery: Suitable for applications in tractors, harvesters, and other farm equipment where contamination resistance is critical.
