6312-2RS1/C3GJN Bearing Product Overview & Core Advantages
The 6312-2RS1/C3GJN is a single row deep groove ball bearing designed for high reliability and robust performance in a wide range of industrial applications. Its key advantage lies in its ability to efficiently accommodate radial loads and moderate axial loads in both directions. The bearing features integral contact seals (2RS1) for effective contamination protection and is supplied pre-lubricated. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers consistent quality and dependable operation, making it a versatile and cost-effective solution for demanding environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6312 | Basic bearing series, indicating a single row deep groove ball bearing with a 60 mm bore, 130 mm OD, and 31 mm width. |
| 2RS1 | Bearing is fitted with two integral contact seals (one on each side) made from Nitrile Rubber (NBR). This provides superior protection against contaminants and retains lubricant. |
| C3 | Specifies a greater than normal radial internal clearance. This is beneficial for applications with significant thermal expansion or where interference fits are used. |
| GJN | Indicates the bearing is filled with a specific polyurea grease. This grease offers good performance across the specified temperature range and contributes to the bearing's long service life. |
6312-2RS1/C3GJN 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 significant radial loads.
- Effective Sealing & Pre-Lubrication: The 2RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants while retaining the factory-applied polyurea grease (GJN). This combination provides a maintenance-free, long-lasting solution, ideal for applications where re-lubrication is difficult.
- Optimized Internal Clearance: The C3 radial internal clearance makes this bearing suitable for applications involving thermal expansion, heavy interference fits, or where a slight reduction in operating noise is acceptable.
- Precision & Reliability: Conforming to ABEC 1 | ISO P0 tolerance class, the bearing guarantees consistent running accuracy and smooth operation, contributing to overall system reliability.
6312-2RS1/C3GJN Bearing Typical Application Areas
