MF148zz Bearing Product Overview & Core Advantages
The MF148zz is a metric miniature deep groove ball bearing designed for compact applications requiring reliable performance. Featuring a single row design and shielded construction, this bearing is optimized for radial load applications. Its small footprint, with an 8 mm bore and 4 mm width, makes it ideal for space-constrained assemblies. Manufactured to ABEC1 precision tolerances, it ensures consistent operation and is pre-lubricated for immediate use, offering a balanced combination of high-speed capability (up to 38,000 rpm) and durability in a miniature package.
MF148zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| MF148 | Basic bearing designation | Identifies the bearing series and bearing dimensions (8mm bore, 14mm OD) |
| zz | Double-sided metal shields (2Z) | Provides effective contamination protection, retaining lubricant and excluding debris for extended service life |
MF148zz Bearing Structural Features & Performance Benefits
Optimized Miniature Design: The deep groove raceway and precision-ground chrome steel components enable smooth operation and efficient radial load handling. The stainless steel cage ensures proper ball guidance and contributes to the high-speed performance.
Shielded Protection: The double-sided 300 series stainless steel shields offer robust protection against contaminants, making the bearing suitable for environments where dust or small particles are present. This design helps maintain lubrication integrity.
Precision Engineering: Manufactured to ABEC1 tolerance class with a controlled MC3 radial internal clearance (0.002mm to 0.013mm), this bearing delivers consistent, low-vibration performance essential for sensitive applications.
MF148zz Bearing Typical Application Areas
The MF148zz is widely used in compact, high-speed devices requiring reliable miniature bearings, including:
- Small Precision Motors (e.g., drones, RC models)
- Office Automation Equipment (e.g., printers, scanners)
- Medical Devices & Instrumentation (e.g., handheld surgical tools, pumps)
- Computer Cooling Fans
- Textile Machinery guidance systems
