6205-ZN/C3 Bearing Product Overview & Core Advantages
The 6205-ZN/C3 is a metric single row deep groove ball bearing engineered for superior performance in demanding industrial applications. This bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a shielded design (ZN) for effective contamination protection and an optimized C3 radial internal clearance for stable operation in applications with thermal expansion or heavy loads. Manufactured from high-grade chrome steel and built to ABEC 1 | ISO P0 tolerance standards, it delivers reliable, long-lasting service in a compact and cost-effective package.
6205-ZN/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| Z | One Shield on One Side | Protects bearing internals from large particulate contaminants. |
| N | Snap Ring Groove on Outer Ring | Facilitates axial location and secure mounting within a housing. |
| C3 | Greater than Normal Radial Internal Clearance | Prevents binding under operational heat or heavy load conditions, ensuring smooth rotation. |
6205-ZN/C3 Bearing Structural Features & Performance Benefits
- Shielded Protection (Z): The steel shield effectively retains lubrication and excludes larger contaminants, enhancing bearing life without significantly increasing rotational torque.
- Optimized Internal Clearance (C3): The C3 clearance is a critical feature for applications prone to thermal expansion or those under heavy loads. It prevents pre-loading and potential seizure, ensuring operational reliability.
- Robust Construction: All components, including the rings, balls, and cage, are manufactured from high-carbon chrome steel (GCr15), providing high hardness, wear resistance, and a long fatigue life.
- Snap Ring Groove (N): The outer ring groove allows for the use of a snap ring, simplifying axial positioning and securing the bearing in the housing, which is ideal for designs where a press-fit is not feasible.
- High-Speed Capability: The precision-ground components and stable cage design contribute to a high limiting speed of 13,000 rpm, making it suitable for a wide range of industrial machinery.
6205-ZN/C3 Bearing Typical Application Areas
The 6205-ZN/C3 is a versatile component found in numerous industrial sectors. Its combination of load capacity, contamination resistance, and high-speed performance makes it ideal for:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- Automotive Components (Alternators, Idlers)
