MF62zz Bearing Product Overview & Core Advantages
The MF62zz is a miniature deep groove ball bearing engineered for precision applications requiring compact dimensions and reliable performance. Featuring a single row design and shielded construction (ZZ), it is optimized for handling primarily radial loads in high-speed environments. Its small footprint, with a bore of just 2 mm and an outside diameter of 6 mm, makes it an ideal solution for space-constrained assemblies demanding high rotational accuracy and smooth operation, as defined by its ABEC1 tolerance class.
MF62zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| MF62 | Indicates the bearing series and size. 'MF' typically denotes a specific miniature flange series, with a 2 mm bore and 6 mm outside diameter. |
| zz | Signifies that the bearing is equipped with non-contact shields on both sides. These shields protect the internal components from large contaminants while minimizing friction, contributing to the high limiting speed. |
MF62zz Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a stainless steel cage, precision-ground chrome steel components, and non-contact ZZ shields allows for a high limiting speed of 75,000 rpm, making it a true high-speed bearing.
- Robust Load Rating: Despite its miniature size, it offers a dynamic load rating of 63 lbf and a static load rating of 18 lbf, providing reliable performance under demanding radial loads.
- Precision & Stability: Manufactured to ABEC1 precision class and featuring a controlled MC3 radial internal clearance (0.002mm to 0.013mm), this bearing ensures smooth, low-vibration, and accurate rotation.
- Integrated Flange: The bearing includes a flange (7.2 mm outer diameter) for simplified mounting and secure axial location within a housing, enhancing assembly rigidity.
- Material Integrity: Constructed from high-grade chrome steel for rings and balls, and stainless steel for the cage and shields, ensuring durability and corrosion resistance.
MF62zz Bearing Typical Application Areas
This bearing is specifically designed for compact, high-speed mechanisms. Key applications include:
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Medical Devices: Used in surgical hand tools, dental drills, and small pump systems.
- Office Automation Equipment: Critical component in scanners, printers, and small fans.
- Instrumentation and Robotics: Provides precise motion control in encoders, sensors, and miniature robotic joints.
- Radio Control Models: Commonly found in high-performance drone motors and RC car transmissions.
