SFRW166zz Bearing Product Overview & Core Advantages
The SFRW166zz is a single row deep groove ball bearing designed for precision applications requiring high reliability. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantages include the ability to handle significant radial loads and its compact, shielded design which helps protect against contamination. This bearing is an ideal choice for applications demanding smooth operation and long service life in challenging environments.
SFRW166zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Benefit |
|---|---|---|
| zz | Non-contact shields on both sides | Provides effective protection against contaminants while maintaining a low torque signature, suitable for higher speeds. |
| - | Extended inner ring | Facilitates easier mounting and axial location, enhancing design flexibility. |
SFRW166zz Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High-Capacity Design: The optimized deep groove geometry enables the bearing to support high radial dynamic load ratings of 122 lbf, ensuring robust performance under demanding conditions.
- Shielded Protection: The non-contact stainless steel shields (zz) effectively seal the bearing, protecting the precision ball complement from dust and debris, thereby extending service life without significantly increasing rotational torque.
- Stainless Steel Construction: All components, including rings, balls, and cage, are made from stainless steel. This provides superior corrosion resistance, making it suitable for a wide temperature range from -86 to 230 °F and for use in washdown or chemically aggressive environments.
- Precision Engineering: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3), this bearing guarantees consistent running accuracy and smooth, low-vibration operation.
SFRW166zz Bearing Typical Application Areas
This bearing is well-suited for a variety of compact and precision-driven applications, including:
- Small precision instruments and medical devices
- Low-torque, high-speed spindles in dental handpieces
- Stepper motors and small servo motors
- Office automation equipment (e.g., printers, scanners)
- Food processing and packaging machinery requiring corrosion resistance
- Various industrial machinery where reliability and compact bearing dimensions are critical
