MF83zz Bearing Product Overview & Core Advantages
The MF83zz is a miniature deep groove ball bearing engineered for compact applications demanding reliable performance. As a metric single row bearing with integral shielded protection (ZZ suffix), it is optimized for radial loads and offers a robust solution in space-constrained designs. Its ABEC1 precision class ensures consistent operation, making it a fundamental component for devices requiring smooth rotation and high limiting speeds up to 60,000 rpm. The combination of chrome steel rings and a stainless steel cage provides excellent durability and corrosion resistance.
MF83zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| MF83 | Basic bearing designation, indicating a specific series with a 3mm bore and 8mm outer diameter. |
| zz | Signifies that the bearing is shielded on both sides. This provides effective protection against contamination while allowing for high-speed operation. |
MF83zz Bearing Structural Features & Performance Benefits
- High-Speed Capability: The lightweight stainless steel cage and optimized internal geometry contribute to a high limiting speed of 60,000 rpm, making it suitable for demanding rotational applications.
- Robust Load Handling: The deep groove raceway and chrome steel construction enable efficient handling of radial dynamic loads (76 lbf) and radial static loads (25 lbf).
- Contamination Protection: The 300 series stainless steel shields (ZZ) retain lubricant and exclude larger particulate contaminants, enhancing bearing service life.
- Precision & Stability: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), this bearing ensures smooth, low-vibration, and precise operation.
- Flanged Design: The integrated flange (9.2mm outer diameter) simplifies mounting and positioning, providing axial location and increasing design stability.
MF83zz Bearing Typical Application Areas
This bearing is ideally suited for a wide range of miniature and precision applications, including:
- Small DC Motors and Stepper Motors
- Precision Instruments and Optical Encoders
- Office Automation Equipment (e.g., Printers, Scanners)
- Medical Devices and Laboratory Equipment
- Small Fans, Spindles, and High-Speed Drives
