SFR2-5 Bearing Product Overview & Core Advantages
The SFR2-5 is a single row deep groove ball bearing designed for precision radial load applications. Manufactured entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance and reliable performance. Its compact inch-series design (0.125" bore) is engineered for high-speed operation up to 54,000 rpm, making it ideal for applications demanding precision and durability in challenging environments.
SFR2-5 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SFR2-5 | Standard Flanged Radial Bearing Series, 0.125" Bore Diameter |
| Open (Seal Type) | No integral seals or shields; requires external sealing for contaminated environments |
| ABEC1 | Standard precision tolerance class suitable for most industrial applications |
| MC3 | Normal radial internal clearance range (0.00008" to 0.0005") |
SFR2-5 Bearing Structural Features & Performance Benefits
All-Stainless Steel Construction: Provides superior corrosion resistance, making it suitable for harsh environments and ensuring long service life.
Flanged Design: The integrated flange (0.359" outer diameter) facilitates precise axial location and simplifies housing design, reducing assembly time and cost.
Deep Groove Raceway: Optimized for handling radial dynamic loads up to 96 lbf, while also capable of supporting moderate axial loads in both directions.
High-Speed Capability: The combination of 6 precision stainless steel balls and a stainless steel cage enables smooth operation at limiting speeds of 54,000 rpm.
SFR2-5 Bearing Typical Application Areas
- Small Precision Motors and stepper motors
- Medical Devices and dental handpieces
- Optical Encoders and precision instrumentation
- Office Automation Equipment (printers, scanners)
- Robotics and small gearboxes
- Food Processing Equipment (where corrosion resistance is critical)
