R3Azz Bearing Product Overview & Core Advantages
The R3Azz is a precision-engineered single row deep groove ball bearing designed for reliable performance in demanding applications. Manufactured to ABEC1 precision class standards, this inch-series bearing features shielded construction for contaminant protection while maintaining excellent radial load capacity. Its compact design with 0.1875" bore diameter and chrome steel construction ensures durability and consistent operation across a wide temperature range from -86 to 230 °F, making it ideal for applications requiring high reliability and precise rotational accuracy.
R3Azz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| R3 | Bore diameter code (0.1875") | Standard inch dimension for compatibility |
| A | Angular contact design variant | Enhanced axial load handling capability |
| zz | Double shielded both sides | Superior contaminant exclusion and lubricant retention |
R3Azz Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design accommodates both radial and moderate axial loads, providing versatile load-carrying capability with 283 lbf dynamic radial load rating and 112 lbf static radial load rating.
Precision Components: Constructed with chrome steel rings and balls combined with a stainless steel cage, ensuring dimensional stability and corrosion resistance. The 300 series stainless steel shields provide effective protection while maintaining low friction operation.
High-Speed Capability: With a limiting speed of 38,000 rpm and MC3 radial internal clearance (0.00008" to 0.0005"), the bearing delivers smooth operation at high rotational speeds while maintaining precise running accuracy.
Optimized Ball Configuration: Features 8 precision balls with 0.0937" diameter arranged in a single row, providing balanced load distribution and reduced vibration for quiet, efficient operation.
R3Azz Bearing Typical Application Areas
- Small Electric Motors: Ideal for fractional horsepower motors requiring reliable operation at moderate to high speeds
