SFR3zz Bearing Product Overview & Core Advantages
The SFR3zz is a single row deep groove ball bearing designed for precision applications requiring reliable radial load capacity. Manufactured entirely from stainless steel with integral shields (zz), this bearing offers excellent corrosion resistance and contaminant protection. Its compact inch-series design (0.1875" bore, 0.5" OD) makes it ideal for space-constrained assemblies in demanding environments, delivering consistent performance across a wide temperature range from -86 to 230 °F.
SFR3zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SFR3 | Basic bearing series designation (inch series) |
| zz | Non-contact shields on both sides for basic contaminant exclusion |
SFR3zz Bearing Structural Features & Performance Benefits
Robust Construction: The single row deep groove raceway and 7 precision balls provide optimal radial load capacity (224 lbf dynamic / 79 lbf static). The all-stainless steel construction (rings, balls, cage) ensures superior corrosion resistance and dimensional stability.
Contaminant Protection: The 300 series stainless steel shields (zz) protect the bearing interior from dust and larger particles while minimizing friction, contributing to the high limiting speed of 38,700 rpm.
Precision Performance: Manufactured to ABEC1 tolerance class with MC3 radial clearance (0.00008" to 0.0005"), this bearing delivers reliable operation in precision mechanical systems.
