SFR156zz Bearing Product Overview & Core Advantages
The SFR156zz is a single row deep groove ball bearing designed for precision applications requiring reliable performance in a compact form factor. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its shielded design provides effective protection against contaminant ingress while maintaining low running torque. This bearing is engineered to handle primarily radial loads and is characterized by its high limiting speed and ABEC1 precision class, making it a robust and dependable choice for high-speed, compact assemblies demanding long service life.
SFR156zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SFR | Manufacturer's series prefix for a specific range of flanged bearings. |
| 156 | Designates the specific bearing size within the series. |
| zz | Indicates the bearing is equipped with non-contact shields on both sides. This offers protection from dust and debris without significantly increasing friction. |
SFR156zz Bearing Structural Features & Performance Benefits
- Compact & Robust Flanged Design: The integrated flange (OD: 0.359") facilitates precise and secure mounting, simplifying assembly and improving positional accuracy within the housing.
- High-Speed Capability: With a limiting speed of 47,700 rpm, the bearing is optimized for high-velocity applications. The stainless steel cage and precision-ground components ensure stable operation.
- Corrosion Resistance: All components, including rings, balls, cage, and shields, are made from stainless steel, making it suitable for harsh environments and wash-down applications.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), ensuring consistent running accuracy and smooth operation.
- Effective Contamination Protection: The non-contact ZZ shields help retain lubrication and exclude larger particulate contaminants, extending bearing life.
SFR156zz Bearing Typical Application Areas
This bearing is ideally suited for applications where compactness, high speed, and corrosion resistance are critical. Common uses include:
- Small Precision Motors and stepper motors
- Medical and Dental Handpieces
- Office Automation Equipment (e.g., printers, scanners)
- Instrumentation and Control Devices
- Food Processing Equipment (due to stainless steel construction)
- Small fans and blowers
