SMF83zz Bearing Product Overview & Core Advantages
The SMF83zz is a metric miniature ball bearing engineered for precision applications requiring compact design and reliable performance. As a single row radial ball bearing, it is optimized to handle primarily radial loads. Its construction from stainless steel throughout provides excellent corrosion resistance, making it suitable for demanding environments. The bearing features shielded seals for contaminant protection and is designed for high limiting speeds, offering a robust solution for high-speed, small-scale mechanisms.
SMF83zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| zz | Non-contact steel shields on both sides. | Provides effective protection against dust and debris while minimizing friction, contributing to the high limiting speed. |
Note: The "SMF83" base code indicates the specific bearing dimensions (3x8x3mm) and the "zz" suffix defines the sealing type.
SMF83zz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of 3x8x3mm and a weight of only 0.59g, this bearing is ideal for space-constrained and weight-sensitive applications.
- High-Speed Capability: The combination of a stainless steel cage, seven precision balls, and non-contact shields allows for a high limiting speed of 54,000 rpm.
- Corrosion Resistance: All components, including rings, balls, cage, and shields, are manufactured from stainless steel, ensuring long-term performance in humid or corrosive environments.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 / 0.002mm to 0.013mm), ensuring smooth and consistent operation.
- Integrated Flange: The flange (9.2mm outer diameter) facilitates secure and simplified mounting, enhancing positional accuracy and assembly efficiency.
SMF83zz Bearing Typical Application Areas
- Small Precision Motors (e.g., drone motors, miniature DC motors)
- Medical and Dental Handpieces
- Office Automation Equipment (e.g., printers, scanners)
- Instrumentation and Control Devices
- Robotics and RC Models
