FR1-4zz Bearing Product Overview & Core Advantages
The FR1-4zz is a miniature single row deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. Manufactured to ABEC1 precision class, this inch-series bearing features stainless steel shields for contaminant protection and is constructed from high-grade chrome steel for durability. Its primary advantages include a high limiting speed of 67,000 rpm and the ability to handle significant radial dynamic loads up to 54 lbf, making it ideal for space-constrained, high-speed mechanisms.
FR1-4zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| FR1-4 | Specifies the bearing series and size: Flanged, single row design with 0.07813" bore and 0.25" outside diameter. |
| zz | Indicates double-shielded construction on both sides, providing effective protection against contaminants while allowing high-speed operation. |
FR1-4zz Bearing Structural Features & Performance Benefits
- Compact Flanged Design: The integrated flange (0.296" OD) enables secure and simplified mounting, reducing assembly time and improving positional accuracy.
- High-Speed Capability: The combination of 7 precision balls, stainless steel cage, and optimized internal geometry enables exceptional rotational performance up to 67,000 rpm.
- Robust Load Capacity:
- Radial dynamic load rating: 54 lbf - Handles substantial radial forces in continuous operation
- Radial static load rating: 17 lbf - Provides reliable performance under stationary or slow-rotation conditions
- Precision Engineering: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3: 0.00008" to 0.0005") ensures consistent performance and smooth operation.
- Material Excellence: Chrome steel rings and balls combined with 300 series stainless steel shields offer excellent corrosion resistance and long service life.
