6204-ZNR/C3 Bearing Product Overview & Core Advantages
The 6204-ZNR/C3 is a single row deep groove ball bearing designed for robust performance in demanding applications. Its key advantage lies in the combination of standard radial load capacity with the convenience of an integrated snap ring (ZNR suffix) for secure axial positioning within housings. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable precision, while the specified C3 radial internal clearance makes it suitable for applications with thermal expansion or where interference fits are used. This bearing is a versatile and cost-effective solution for general industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6204 | Basic bearing series and size designation (20mm bore, 47mm OD, 14mm width). |
| Z | Shield on one side, protecting the bearing from contaminants. |
| NR | Snap ring groove and snap ring fitted on the outer ring. This facilitates simplified housing design and secure axial location. |
| /C3 | Specifies a greater than normal radial internal clearance, ideal for applications with elevated temperatures or tight interference fits. |
6204-ZNR/C3 Bearing Structural Features & Performance Benefits
- Snap Ring for Simplified Assembly: The integrated snap ring eliminates the need for complex housing shoulders or end caps, reducing manufacturing costs and simplifying bearing installation and axial retention.
- Robust Contamination Protection: The shielded design (Z) effectively protects the internal components from large particulate contaminants, enhancing bearing service life in challenging environments.
- Optimized for Thermal & Fit Conditions: The C3 clearance provides operational reliability in applications where shaft or housing fits, or operational heat, would cause a standard clearance bearing to bind.
- High-Quality Material Construction: Built entirely from chrome steel, this bearing ensures high strength, durability, and consistent performance under dynamic radial loads.
6204-ZNR/C3 Bearing Typical Application Areas
This bearing is commonly specified in applications requiring secure axial location and reliable performance, including:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Agricultural Machinery
- Conveyor Systems
- Material Handling Equipment
