6205-ZNR/C3 Bearing Product Overview & Core Advantages
The 6205-ZNR/C3 is a single row deep groove ball bearing engineered for robust performance in demanding applications. This metric bearing features a snap ring groove on its outer ring, enabling secure axial positioning within housings without requiring complex machining. Its C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used. The combination of shielded construction and precision ABEC 1 | ISO P0 tolerance ensures reliable operation while maintaining cost-effectiveness for industrial applications requiring consistent radial load capacity.
6205-ZNR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| Z | Single Shield on One Side | Protects against contaminants while allowing higher speeds than contact seals |
| NR | Snap Ring Groove with Snap Ring | Enables simplified housing design and secure axial location |
| C3 | Greater than Normal Radial Clearance | Accommodates thermal expansion and interference fits |
6205-ZNR/C3 Bearing Structural Features & Performance Benefits
Deep Groove Raceway Design: The optimized raceway geometry provides excellent radial load capacity (3147 lbf dynamic, 1765 lbf static) while accommodating moderate axial loads in both directions.
Snap Ring Integration: The integrated snap ring (57.9 mm outside diameter, 1.12 mm width) eliminates the need for additional housing shoulders or complex retention methods, reducing assembly time and cost.
Shielded Protection: The single steel shield effectively excludes contaminants while maintaining high-speed capability up to 13,000 rpm, significantly higher than contact-sealed alternatives.
Premium Material Construction: Manufactured from chrome steel for rings, balls, and cage, ensuring consistent performance and durability across the operating temperature range of -30°C to 120°C.
Optimized Clearance: The C3 radial clearance provides operational stability in applications subject to thermal variations or where press fits are employed.
6205-ZNR/C3 Bearing Typical Application Areas
- Electric Motors: Ideal for industrial motor applications requiring secure housing location and contaminant protection
- Gearboxes & Transmissions: Suitable for power transmission systems where thermal expansion must be accommodated
- Material Handling Equipment: Conveyor systems, pulley assemblies, and other machinery requiring reliable bearing performance
- Agricultural Machinery: Farm equipment applications where simplified installation and maintenance are critical
- Industrial Pumps & Fans: Medium-duty rotating equipment requiring balanced performance and cost-effectiveness
