6208 TB Bearing Product Overview & Core Advantages
The 6208 TB is a high-performance single row deep groove ball bearing engineered for robust radial load capacity and reliable operation. As a metric bearing with an open design, it is optimized for applications requiring high rotational speeds and precise operation under standard tolerance class ABEC 1 | ISO P0. Its construction from high-grade chrome steel ensures durability and a long service life, making it a fundamental and versatile component for industrial machinery.
6208 TB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6208 | Standard bearing series designation indicating dimensions: 40mm bore, 80mm OD, 18mm width. |
| TB | Denotes a snap-ring groove on the outer ring, allowing for secure axial location within a housing. |
6208 TB Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The single row deep groove raceway geometry is optimized to support high radial dynamic load ratings of 6542 lbf and radial static load ratings of 4002 lbf, ensuring reliable performance under significant stress.
- High-Speed Capability: With a limiting speed of 8,300 rpm, this bearing is suitable for demanding high-rotation applications. The open seal type minimizes friction and heat generation at high speeds.
- Precision & Stability: Manufactured to ABEC 1 | ISO P0 tolerance standards with a standard CN radial internal clearance, it provides consistent and precise running accuracy for smooth operation.
- Secure Axial Location: The integrated snap-ring groove (TB) on the outer ring simplifies assembly and provides a positive axial location, preventing creep in the housing.
- Durable Construction: All critical components, including rings, balls, and cage, are manufactured from chrome steel, offering excellent resistance to wear and fatigue.
6208 TB Bearing Typical Application Areas
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring secure bearing location
