SFRW0 Bearing Product Overview & Core Advantages
The SFRW0 is a miniature single row deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its open design allows for versatile lubrication options, making it suitable for high-speed operation up to 99,000 rpm. The bearing is engineered to handle primarily radial loads and is characterized by its extended inner ring, which facilitates easier mounting and axial location.
SFRW0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SFRW0 | Model designation for this specific series of miniature, stainless steel, flanged ball bearings. |
| N/A (Open) | The bearing is supplied without seals or shields, indicating an open seal type. |
| N/A (Extended Inner Ring) | The inner ring type is extended beyond the bearing width. |
SFRW0 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a weight of only 0.2 grams, this bearing is ideal for space-constrained and weight-sensitive applications.
- High-Speed Capability: The single row deep groove geometry and stainless steel cage contribute to a high limiting speed of 99,000 rpm.
- Corrosion Resistance: All components, including rings, balls, and cage, are made from stainless steel, ensuring reliable performance in harsh environments and a wide temperature range from -86 to 230 °F.
- Precision & Stability: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3), providing consistent running accuracy.
- Flanged Outer Ring: The integral flange (Flange outer diameter: 0.203") simplifies housing design and provides secure axial location, preventing creeping.
SFRW0 Bearing Typical Application Areas
- Precision Small Motors and Spindles
- Medical and Dental Handpieces
- Optical Encoders and Scanners
- Instrumentation and Control Devices
- Small Robotics and Automation Equipment
- Office Machinery and Consumer Electronics
