SFR1-5 Bearing Product Overview & Core Advantages
The SFR1-5 is a precision miniature ball bearing engineered for demanding applications requiring high reliability in compact spaces. As a single row deep groove ball bearing, it is primarily designed to support radial loads efficiently. Manufactured entirely from stainless steel, it offers excellent corrosion resistance and is suitable for a wide temperature range from -86 to 230 °F. Its open design allows for versatile lubrication options, making it a fundamental component for high-speed, low-torque operations in various industries.
SFR1-5 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| SFR | Series designation for miniature flanged bearings. |
| 1-5 | Specifies the specific bearing size within the series, defining the bore, outer diameter, and width. |
| (Implied: Open) | The bearing features an open seal type, meaning it is unshielded and requires external lubrication for optimal performance. |
SFR1-5 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a weight of only 0.67 g and a compact flange outer diameter of 0.359", this bearing is ideal for space-constrained applications. The integral flange simplifies mounting and positioning.
- High-Speed Capability: The stainless steel cage and optimized internal geometry contribute to a high limiting speed of 54,000 rpm, making it suitable for high-rotation mechanisms.
- Precision Performance: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3 group), this bearing ensures smooth and consistent operation with minimal vibration.
- Corrosion Resistance: All components, including rings, balls, and cage, are made from stainless steel, providing excellent protection against rust and corrosion in harsh environments.
- Radial Load Capacity: Engineered to handle significant radial dynamic load ratings of 95 lbf and static load ratings of 29 lbf for its size.
SFR1-5 Bearing Typical Application Areas
- Small Precision Motors and Stepper Motors
- Medical Devices and Instrumentation
- Optical Encoders and Scanning Equipment
- Office Automation Equipment (Printers, Scanners)
- Radio Control Models and Drones
- Textile Machinery Guides and Spindles
- Food Processing Equipment (where corrosion resistance is critical)
