6220-Z Bearing Product Overview & Core Advantages
The 6220-Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with metric dimensions and manufactured to P6 tolerance class, it delivers high precision and reliability. Its core strength lies in its ability to efficiently handle radial loads, supported by a high radial dynamic load rating of 28,551 lbf. The inclusion of shielded seals (Z-type) protects against contamination while the pre-lubricated grease ensures smooth operation and reduced maintenance needs, making it a robust and long-lasting solution for industrial machinery.
6220-Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6220 | Basic bearing designation indicating a single row deep groove ball bearing with a 100 mm bore and 180 mm outside diameter. |
| -Z | Denotes a non-contact shield on one side. This provides effective protection against large particulate contaminants while minimizing friction and heat generation. |
6220-Z Bearing Structural Features & Performance Benefits
- High Load Capacity & Precision: The single row deep groove raceway and chrome steel construction provide high radial dynamic and static load ratings, ensuring dependable performance under significant stress. Manufactured to P6 tolerance and standard CN radial internal clearance, it guarantees precise running accuracy and low vibration.
- Optimized for Durability: The stainless steel cage offers excellent corrosion resistance and durability, contributing to stable operation at the limiting speed of 4,800 rpm. The combination of high-grade materials ensures a long service life.
- Enhanced Protection & Maintenance: The shielded design (Z) effectively seals the bearing from external debris. Being pre-lubricated with grease, it is ready for immediate use and offers a maintenance-free solution within its specified temperature range of -30°C to 120°C.
6220-Z Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial applications requiring robust radial load support and reliable operation, including:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Fans
