6308-2RS1/C3 Bearing Product Overview & Core Advantages
The 6308-2RS1/C3 is a metric single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. This sealed bearing features a C3 radial internal clearance, making it ideal for applications with elevated operating temperatures or where interference fits are used. Its primary advantages include robust construction from chrome steel, effective sealed protection against contamination, and a design optimized to handle significant radial loads with high reliability.
6308-2RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6308 | Basic bearing series; indicates a medium duty, single row deep groove ball bearing with a 40mm bore, 90mm OD, and 23mm width. |
| 2RS1 | The bearing is equipped with two contact seals (one on each side) made from Nitrile Rubber (NBR). This provides superior protection against dust, moisture, and other contaminants, helping to retain lubricant. |
| C3 | Specifies a greater than normal radial internal clearance. This is beneficial for applications involving thermal expansion, heavy interference fits, or where lower operating temperatures are required. |
6308-2RS1/C3 Bearing Structural Features & Performance Benefits
- Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers a high radial dynamic load rating of 915 lbf and a radial static load rating of 5395 lbf, ensuring durability under substantial loads.
- Effective Sealing Solution: The 2RS1 contact seals provide an effective barrier, protecting the bearing's interior from contaminants and preventing lubricant leakage, which extends service life and reduces maintenance needs.
- Optimized Internal Clearance: The C3 clearance accommodates dimensional changes from thermal expansion and press-fits, preventing excessive preload and ensuring smooth, reliable operation.
- Standard Precision: Conforms to ABEC 1 | ISO P0 tolerance class, providing consistent and reliable performance for a wide range of general industrial applications.
6308-2RS1/C3 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- General Machinery requiring reliable, sealed bearing solutions
