R4Azz Bearing Product Overview & Core Advantages
The R4Azz is a precision single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity and smooth operation. Manufactured to ABEC1 tolerance class, this inch-series bearing features 300 Series stainless steel shields for effective contamination protection. Its compact design with a 0.25" bore and 0.75" outside diameter makes it ideal for space-constrained applications where consistent performance is critical.
R4Azz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| R4 | Basic bearing series designation for inch-size deep groove ball bearings |
| A | Angular design with optimized internal geometry |
| zz | Double shielded construction providing protection from contaminants on both sides |
R4Azz Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables efficient handling of radial loads up to 446 lbf dynamic capacity, while accommodating moderate axial loads in both directions.
Shielded Protection: The stainless steel shields (zz) provide effective sealing against dust and debris while minimizing friction, contributing to the bearing's limiting speed of 36,000 rpm.
Precision Engineering: Manufactured to ABEC1 tolerance standards with MC3 radial internal clearance (0.00008" to 0.0005"), ensuring consistent performance and smooth operation across the temperature range of -86 to 230 °F.
Durable Construction: All-steel components including chrome steel rings and balls with stainless steel cage provide excellent durability and corrosion resistance in demanding environments.
