6308-2RS1/WT Bearing Product Overview & Core Advantages
The 6308-2RS1/WT is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This metric bearing features integral contact seals (2RS1) for superior contamination protection and is manufactured to ABEC 1 | ISO P0 precision tolerances. Its optimized internal geometry enables high limiting speeds while effectively handling significant radial loads. The combination of robust construction and sealed design makes it an ideal, long-lasting solution for various industrial machinery.
6308-2RS1/WT Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| -2RS1 | Double Contact Seals (NBR Rubber) | Provides excellent protection against contaminants like dust and moisture, extending bearing service life. |
| /WT | Wide Temperature Range Grease | Enables reliable operation across a broad temperature range from -30°C to 120°C. |
6308-2RS1/WT Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from high-grade chrome steel for both rings, balls, and cage, this bearing delivers a high radial dynamic load rating of 915 lbf and a radial static load rating of 5395 lbf, ensuring durability under significant stress.
- Optimized Sealing & Lubrication: The double contact seals (2RS1) effectively retain the factory-applied, wide-temperature grease and exclude harmful contaminants. This creates a maintenance-free system ideal for applications where re-lubrication is difficult.
- Precision & High-Speed Capability: Built to ABEC 1 precision with standard CN radial internal clearance, it ensures smooth operation and low vibration, contributing to its high limiting speed of 7,500 rpm.
6308-2RS1/WT Bearing Typical Application Areas
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring reliable, sealed ball bearings
