6208-2Z/C4 Bearing Product Overview & Core Advantages
The 6208-2Z/C4 is a single row deep groove ball bearing engineered for high reliability in demanding applications. This shielded bearing features a robust construction that provides excellent performance under radial loads. Its key advantages include a generous C4 radial internal clearance for applications involving thermal expansion, and integrated shields (2Z) that protect against contamination while being maintenance-free. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and long service life.
6208-2Z/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6208 | Basic bearing designation: Deep Groove Ball Bearing, 40mm bore, 80mm OD, 18mm width. |
| 2Z | Bearing is equipped with shields on both sides. This provides effective protection against solid contaminants while allowing for high-speed operation. |
| C4 | Specifies a greater than normal radial internal clearance. This is critical for applications where thermal expansion of the shaft or housing is expected, preventing preload and potential bearing seizure. |
6208-2Z/C4 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove raceway and high-quality chrome steel construction provide a high radial dynamic load rating of 6542 lbf and a static load rating of 4002 lbf, ensuring durability under significant stress.
- Contamination Protection: The non-contact shields (2Z) on both sides effectively seal the bearing against dust and debris without generating significant friction, contributing to a limiting speed of 8,300 rpm.
- Thermal Stability: The C4 radial clearance is a key structural feature that accommodates differential thermal expansion between the bearing and its surrounding components, making it suitable for applications with fluctuating operational temperatures.
- Precision & Consistency: Manufactured to ABEC 1 (ISO P0) tolerance class, this bearing ensures smooth and precise rotation, which is essential for reducing vibration and noise in machinery.
6208-2Z/C4 Bearing Typical Application Areas
The 6208-2Z/C4 is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems
- Agricultural Machinery
- Material Handling Equipment
Its combination of shielded protection and increased internal clearance makes it a robust choice for applications where reliability and minimal maintenance are critical.
