608-2Z/C4 Bearing Product Overview & Core Advantages
The 608-2Z/C4 is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. This shielded bearing offers excellent protection against contamination while maintaining smooth operation. A key feature is its C4 radial internal clearance, which is greater than normal, making it suitable for applications involving thermal expansion or where interference fits are used. Its compact design, combined with a high-quality chrome steel construction, ensures durability and consistent operation under radial loads.
Model Code Breakdown
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| 2Z | Non-contact steel shields on both sides | Provides effective protection from dust and other contaminants while minimizing friction and heat generation. |
| C4 | Radial internal clearance greater than Normal (C0) | Accommodates thermal expansion and interference fits, preventing premature failure due to excessive preload. |
608-2Z/C4 Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing provides high strength and resistance to wear, ensuring a long service life.
- Optimized Load Capacity: The single row deep groove raceway is engineered to handle significant radial dynamic loads (630 lbf) and radial static loads (248 lbf) efficiently.
- Shielded Protection: The non-contact 2Z shields retain the factory-applied lubrication and protect the internal components from particulate contamination, enhancing reliability in dirty environments.
- Controlled Internal Clearance: The C4 clearance is critical for applications with expected thermal gradients or shaft/housing interference, preventing binding and reducing operational noise and heat.
608-2Z/C4 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Small Gearboxes
- Power Tools and Appliances
- Conveyor System Idler Rolls
- Fans and Blowers
- Office Machinery and Computer Cooling Fans
- Automotive Auxiliary Units (e.g., alternators)
