SFR6zz Bearing Product Overview & Core Advantages
The SFR6zz is a single row deep groove ball bearing designed for precision and reliability in demanding applications. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its compact design and shielded construction provide effective protection against contaminants while maintaining low friction. This bearing is engineered to primarily handle radial loads and is characterized by its high limiting speed and consistent performance across a wide temperature range, making it a robust solution for various industrial and precision equipment.
SFR6zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| zz | Indicates the bearing is equipped with non-contact shields on both sides. This provides effective protection against dust and other particulate contaminants while minimizing friction and torque, suitable for high-speed operation. |
SFR6zz Bearing Structural Features & Performance Benefits
- Robust Construction: The single row deep groove raceway and complement of 7 precision balls enable smooth operation and efficient radial load capacity.
- High-Speed Capability: The non-contact zz shields and optimized internal geometry contribute to a high limiting speed of 28,800 rpm.
- Corrosion Resistance: All critical components, including rings, balls, and cage, are made from stainless steel, ensuring long service life in harsh or washdown environments.
- Precision & Stability: Built to ABEC1 tolerance class with a controlled radial internal clearance (MC3), this bearing delivers reliable and consistent performance.
SFR6zz Bearing Typical Application Areas
- Precision Medical Devices
- Food Processing and Packaging Machinery
- Small Electric Motors and Gearboxes
- Office Automation Equipment (Printers, Scanners)
- Instrumentation and Measurement Devices
- Low-Torque, High-Speed Spindles
