SFR1zz Bearing Product Overview & Core Advantages
The SFR1zz is a stainless steel miniature ball bearing designed for precision applications requiring reliable performance in compact spaces. As a single row radial ball bearing with shielded construction, it offers excellent protection against contamination while maintaining smooth operation. Its primary advantages include corrosion resistance due to all-stainless-steel components, consistent performance across a wide temperature range (-86 to 230 °F), and compliance with ROHS and REACH environmental standards. The bearing's optimized design delivers stable radial load capacity while maintaining minimal dimensional tolerances for precise positioning applications.
SFR1zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| SFR1 | Basic bearing designation indicating inch-series miniature bearing with specific dimensions | Standardized sizing for interchangeability and precise fit |
| zz | Dual shielded design (both sides protected) | Enhanced contamination protection and extended service life |
SFR1zz Bearing Structural Features & Performance Benefits
All-Stainless-Steel Construction: The bearing features stainless steel rings, balls, cage, and shields, providing excellent corrosion resistance and making it suitable for harsh environments and washdown applications.
Shielded Protection: The dual stainless steel shields effectively protect against dust and particulate contamination while retaining lubrication, contributing to maintenance-free operation in many applications.
Precision Engineering: Manufactured to ABEC1 tolerance class with MC3 radial internal clearance (0.00008" to 0.0005"), ensuring consistent performance and smooth operation in precision mechanisms.
Optimized Load Capacity: With a radial dynamic load rating of 40 lbf and static load rating of 11 lbf, the bearing provides reliable performance in compact spaces while maintaining a limiting speed of 81,000 rpm.
Compact Design: The miniature dimensions (0.05556" bore × 0.1875" OD × 0.1094" width) with integrated flange (0.234" OD) enable space-saving installations and simplified mounting procedures.
