SFR2zz Bearing Product Overview & Core Advantages
The SFR2zz is a single row deep groove ball bearing designed for precision applications requiring reliable radial load capacity and compact dimensions. Manufactured entirely from stainless steel components, it offers excellent corrosion resistance. The inclusion of stainless steel shields (ZZ) provides effective contamination protection while the ABEC1 precision class ensures consistent performance for general industrial use. Its lightweight design and high limiting speed make it ideal for demanding, high-RPM applications.
SFR2zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SR | Prefix denoting a specific series of miniature bearings |
| 2 | Size series identifier |
| ZZ | Shielded on both sides providing non-contact protection against contaminants |
SFR2zz Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: Optimized for high radial dynamic load rating (109 lbf) while accommodating moderate axial loads in both directions.
- Full Stainless Steel Construction: Rings, balls, cage, and shields are all stainless steel, ensuring corrosion resistance and suitability for a wide temperature range (-86 to 230 °F).
- Stainless Steel Shield (ZZ): Non-contact shields retain lubricant and exclude large contaminants, contributing to longer service life without significantly increasing friction.
- Precision Engineering: Built to ABEC1 tolerance class with controlled radial internal clearance (MC3) for smooth, low-vibration operation.
- High-Speed Capability: The combination of a 7-ball complement and a stainless steel cage enables a high limiting speed of 50,400 rpm.
SFR2zz Bearing Typical Application Areas
- Small Precision Motors and Stepper Motors
- Medical Devices and Dental Handpieces
- Optical Encoders and Precision Instruments
- Office Automation Equipment (e.g., printers, scanners)
- Radio Control Models and Small Fans
