6312-2RS1/C3LT20 Bearing Product Overview & Core Advantages
The 6312-2RS1/C3 is a high-performance single row deep groove ball bearing designed for robust operation in demanding industrial environments. Its key advantage lies in its sealed design with two contact seals (2RS1), providing superior protection against contaminants and moisture retention. Pre-lubricated for life, this bearing offers a reliable, maintenance-free solution, while the C3 radial internal clearance ensures optimal performance under varying thermal and load conditions, making it an ideal choice for applications requiring high reliability and long service life.
6312-2RS1/C3LT20 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 60mm bore, 130mm OD, and 31mm width. |
| 2RS1 | Sealing Type | Features two NBR contact seals on both sides. Provides excellent sealing effectiveness against dust, dirt, and moisture. |
| C3 | Radial Internal Clearance | Indicates a greater than normal radial internal clearance. Suitable for applications with significant thermal expansion or heavy interference fits. |
6312-2RS1/C3LT20 Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS1 contact seals are integrally molded from NBR, offering superior exclusion of contaminants and retention of grease compared to non-contact shields, significantly extending bearing life in harsh environments.
- High Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 18,412 lbf and a static load rating of 11,735 lbf, ensuring dependable performance under substantial radial loads.
- Optimized for Operational Stability: The C3 clearance accommodates dimensional changes caused by heat generation or press-fits, preventing premature failure due to excessive preload and ensuring smooth, reliable operation.
- Maintenance-Free & Ready-to-Install: The bearing is pre-lubricated with high-quality grease and sealed for life, eliminating the need for re-lubrication and reducing overall maintenance costs.
