MF105zz Bearing Product Overview & Core Advantages
The MF105zz is a miniature metric ball bearing engineered for high-speed operation and reliable performance in compact spaces. As a single row, shielded radial ball bearing, it is designed to primarily handle radial loads efficiently. Its construction offers a superior balance of precision, durability, and compact dimensions, making it an ideal component for applications demanding high rotational speeds and consistent operation with minimal maintenance.
MF105zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| MF105 | Bearing Series & Size | Identifies the miniature metric series with a 5mm bore, 10mm OD, and 4mm width. |
| zz | Shielded on Both Sides | Indicates the bearing is fitted with non-contact stainless steel shields on both sides, offering effective protection against contaminants while allowing for high-speed performance. |
MF105zz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a bore diameter of 5mm, outside diameter of 10mm, and a width of just 4mm, this bearing is designed for space-constrained applications. Its low weight of 1.38g minimizes rotational inertia.
- High-Speed Capability: The combination of a stainless steel cage, precision ABEC1 tolerance class, and optimized MC3 radial internal clearance enables a high limiting speed of 50,000 rpm.
- Robust Load Capacity: Manufactured from chrome steel rings and balls, it provides a dynamic load rating of 82 lbf and a static load rating of 30 lbf, ensuring reliable performance under radial loads.
- Enhanced Contamination Protection: The double-shielded (zz) design, using 300 series stainless steel, protects the internal components from dust and debris, extending service life and reducing maintenance needs.
MF105zz Bearing Typical Application Areas
This bearing is widely used in:
- Small Precision Motors (e.g., stepper motors, DC motors)
- Office Automation Equipment (e.g., printers, scanners, copiers)
- Medical Devices & Instrumentation
- Robotics & Small Actuators
- Computer Cooling Fans and small spindles
