SFRW2-5 Bearing Product Overview & Core Advantages
The SFRW2-5 is a single row deep groove ball bearing designed for precision applications requiring high reliability. Manufactured entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. This bearing is engineered to primarily handle radial loads and is characterized by its compact, flanged design for secure mounting and precise axial location. Its ABEC1 precision class and consistent performance make it a dependable choice for high-speed, compact mechanisms.
SFRW2-5 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SFRW2-5 | Standard model number for this specific inch-series, flanged, deep groove ball bearing. |
| Single Row / Open | Indicates the bearing has no integral seals or shields, allowing for higher speeds but requiring external lubrication and protection from contaminants. |
| Extended Inner Ring | The inner ring protrudes beyond the bearing width, facilitating easier locking and positioning on a shaft. |
| Flanged | Features an outer ring flange for simplified housing design and accurate axial location without complex machining. |
SFRW2-5 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open design and stainless steel cage minimize friction and drag, enabling operation at a high limiting speed of 99,000 rpm.
- Corrosion Resistance: Constructed entirely from stainless steel, this bearing is ideal for applications exposed to moisture, chemicals, or demanding environments within its temperature range of -86 to 230 °F.
- Precision & Smooth Operation: The ABEC1 tolerance class and optimized radial internal clearance (MC3 group) ensure smooth, low-vibration, and precise running, essential for sensitive equipment.
- Robust Flange Design: The integrated flange simplifies assembly, provides secure mounting, and resists creep, enhancing the overall system's rigidity and reliability.
- Compact & Lightweight: With an overall weight of just 0.2 grams and compact bearing dimensions, it is perfectly suited for space-constrained and weight-sensitive applications.
SFRW2-5 Bearing Typical Application Areas
This bearing is commonly specified in:
- Small Precision Motors and stepper motors
- Medical Devices and dental handpieces
- Optical Encoders and precision instrumentation
- Office Automation Equipment (e.g., scanners, printers)
- Radio Control Models and miniature machinery
- Various industrial applications requiring a compact, corrosion-resistant bearing
