MF52zz Bearing Product Overview & Core Advantages
The MF52zz is a miniature shielded ball bearing engineered for precision applications requiring compact dimensions and reliable performance. As a single row deep groove ball bearing, it is primarily designed to support radial loads efficiently. Its key advantages include a compact design with a 2mm bore, making it ideal for space-constrained assemblies, and the inclusion of stainless steel shields (ZZ) to protect against contamination. Manufactured to ABEC1 precision tolerances, this bearing offers a cost-effective solution for applications demanding consistent operation and high rotational speeds up to 85,000 rpm.
MF52zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| MF52 | Bearing series and size designation | Identifies the specific miniature bearing series with a 2mm bore and 5mm outer diameter. |
| zz | Double-sided metal shields | Provides effective protection from dust and debris, retaining lubrication and extending service life. The shields are non-contact to minimize friction. |
MF52zz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of 2mm (bore) x 5mm (OD) x 2.5mm (width) and a weight of only 0.25 grams, this bearing is engineered for miniature and micro-mechanical systems.
- High-Speed Capability: The combination of a stainless steel cage, precision-ground chrome steel components, and optimized internal geometry enables a limiting speed of 85,000 rpm.
- Robust Construction: Components made from chrome steel (rings, balls) and a stainless steel cage offer excellent resistance to wear and corrosion, ensuring long-term durability.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3: 0.002mm to 0.013mm), this bearing provides smooth, low-vibration, and low-noise operation.
MF52zz Bearing Typical Application Areas
This miniature bearing is ideally suited for:
- Small Precision Motors: Such as those used in drones, RC models, and small fans.
- Medical Devices & Instrumentation: Including dental handpieces, miniature pumps, and optical equipment.
- Office Automation Equipment: Printers, scanners, and copiers.
- High-Speed Spindles: In small-scale CNC and engraving machines.
- Precision Gearboxes and Encoders: Where compact size and reliable rotation are critical.
