6308-2Z/C3HT Bearing Product Overview & Core Advantages
The 6308-2Z/C3 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while also accommodating moderate axial loads in both directions. The combination of shielded construction and a C3 radial internal clearance makes it an ideal choice for applications requiring robust operation, extended service life, and reliable performance under varying thermal conditions. This bearing offers a compact design and is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring consistent quality and high reliability.
6308-2Z/C3HT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6308 | Basic Bearing Series & Size | Denotes a medium-duty, single row deep groove ball bearing with a 40mm bore, 90mm OD, and 23mm width. |
| 2Z | Shielded on Both Sides | Provides effective protection against contamination from solid particles, enhancing bearing life in dirty environments. It is a non-contact seal, minimizing friction. |
| C3 | Radial Internal Clearance | Indicates a clearance greater than normal (CN). This is crucial for applications with thermal expansion, preventing preload and seizure at elevated operating temperatures. |
6308-2Z/C3HT Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing delivers high strength and durability. With a radial dynamic load rating of 915 lbf and a static load rating of 5395 lbf, it is engineered to handle significant radial stresses.
- Optimized for Thermal Stability: The specified C3 clearance is a critical feature, allowing for axial displacement of the rings relative to each other. This prevents binding and reduces friction heat build-up, making it suitable for applications where operating temperatures may vary.
- Contamination Resistance & Low Maintenance: The 2Z shields effectively retain the factory-applied grease and protect the internal components from dust and debris, contributing to a long, maintenance-free service interval.
- Precision & Smooth Operation: Built to ABEC 1 precision class, it ensures smooth rotation and low vibration, which is essential for the efficient operation of motors and general machinery.
6308-2Z/C3HT Bearing Typical Application Areas
