6208-Z/C4 Bearing Product Overview & Core Advantages
The 6208-Z/C4 is a single row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing excels in handling primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a shielded design for contaminant protection, a generous C4 radial internal clearance for thermal expansion management in high-temperature or high-speed operations, and a high radial dynamic load rating of 6542 lbf, ensuring long service life and reliability. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a cost-effective solution for a wide range of industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6208 | Standard deep groove ball bearing series with 40 mm bore and 80 mm outside diameter. |
| -Z | Denotes a shielded bearing on one side. This non-contact shield protects against large contaminants while minimizing friction. |
| /C4 | Indicates a greater than normal radial internal clearance. This is critical for applications with significant thermal expansion or where interference fits are used. |
6208-Z/C4 Bearing Structural Features & Performance Benefits
- Shielded Protection: The Z-shield effectively prevents the ingress of large particulate contaminants, extending bearing life without significantly increasing rotational torque, making it suitable for applications where sealing is required but full-contact seals are not.
- Optimized Internal Clearance: The C4 clearance group provides extra space between the rolling elements and raceways. This is a vital feature for applications prone to thermal expansion, such as electric motors, or where tight press fits are applied, preventing premature failure due to excessive preload.
- High Load Capacity & Durability: Constructed entirely from chrome steel (rings, balls, and cage), this bearing delivers high strength and wear resistance. The high radial dynamic load rating ensures reliable operation under significant loads.
- Precision & Speed: Manufactured to ABEC 1 | ISO P0 tolerances, it provides consistent and precise running. The limiting speed of 8,300 rpm makes it suitable for a variety of high-speed applications.
6208-Z/C4 Bearing Typical Application Areas
The 6208-Z/C4 is a versatile component found in numerous industrial sectors. Its combination of load capacity, speed capability, and contamination protection makes it ideal for:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Fans
