SFRW0zz Bearing Product Overview & Core Advantages
The SFRW0zz is a precision miniature ball bearing designed for applications demanding compact size and reliable performance. As a single row radial ball bearing with an extended inner ring and shielded construction, it excels in providing smooth operation and handling radial loads efficiently. Manufactured entirely from stainless steel, it offers excellent corrosion resistance, making it suitable for challenging environments. Its compact dimensions and ABEC1 tolerance class ensure high reliability in precision assemblies.
SFRW0zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SFR | Indicates a flanged radial ball bearing series. |
| W | Signifies a stainless steel construction for enhanced corrosion resistance. |
| 0zz | Denotes the specific size and variant. The "zz" suffix indicates that the bearing is shielded on both sides to protect against contamination. |
SFRW0zz Bearing Structural Features & Performance Benefits
- Extended Inner Ring & Flange Design: The extended inner ring facilitates easier mounting and axial location, while the integral flange provides secure housing fixation, preventing axial displacement and simplifying assembly.
- Stainless Steel Construction: All components, including rings, balls, cage, and shields, are made from stainless steel, ensuring superior corrosion resistance and durability in humid or chemically aggressive environments.
- Double-Shielded (zz) Protection: Shields on both sides effectively retain lubricant and exclude larger particulate contaminants, enhancing bearing service life and reliability, though lubrication is still required for optimal performance.
- Precision Performance: Built to ABEC1 precision class standards with a controlled MC3 radial internal clearance, this bearing delivers smooth, low-noise, and low-vibration operation suitable for precision instruments.
- High-Speed Capability: With a limiting speed of 99,000 rpm, it is engineered for high-speed applications, supported by its stable stainless steel cage and optimized internal geometry.
SFRW0zz Bearing Typical Application Areas
This miniature flanged bearing is ideal for a wide range of compact and precision devices, including:
- Small Precision Motors (e.g., stepper motors, coreless motors)
- Medical and Dental Handpieces
- Optical Encoders and Scanners
- Office Automation Equipment (e.g., printers, scanners)
- Radio Control Models and Drones
- Instrumentation and Control Devices
