SMR83zz Bearing Product Overview & Core Advantages
The SMR83zz is a metric miniature ball bearing designed for precision applications requiring reliable performance in compact spaces. As a single row radial ball bearing constructed entirely from stainless steel, it offers excellent corrosion resistance. Its shielded design provides effective contamination protection while maintaining low friction. This bearing is engineered to handle primarily radial loads with high efficiency, making it ideal for applications demanding high rotational speeds up to 54,000 rpm while maintaining ABEC1 precision tolerance for consistent operation.
SMR83zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| SMR83 | Basic bearing designation indicating 3mm bore, 8mm OD, 3mm width | Defines the compact bearing dimensions for space-constrained applications |
| zz | Double-sided steel shields (non-contact type) | Provides effective contamination protection while allowing high-speed operation |
SMR83zz Bearing Structural Features & Performance Benefits
Compact Design & High Precision: With dimensions of 3×8×3mm and ABEC1 tolerance class, this bearing delivers precise rotational accuracy in miniature applications. The optimized radial internal clearance (MC3: 0.002-0.013mm) ensures smooth operation across varying temperature conditions.
Stainless Steel Construction: All components including rings, balls, cage, and shields are manufactured from stainless steel, providing excellent corrosion resistance and making it suitable for harsh environments and medical applications.
High-Speed Capability: The 7-ball design with 1.2mm diameter balls and stainless steel cage enables stable operation at limiting speeds of 54,000 rpm, making it ideal for high-speed miniature applications.
Load Performance: With a dynamic load rating of 68 lbf and static load rating of 23 lbf, this bearing provides reliable performance in applications requiring continuous operation under radial loads.
