Product Overview and Core Advantages
The MF117zz is a miniature shielded ball bearing designed for precision applications requiring compact dimensions and reliable performance. This single row deep groove ball bearing features integral shields for contaminant protection and is engineered to handle primarily radial loads efficiently. Its compact design, with a 7mm bore and 11mm outer diameter, makes it ideal for space-constrained assemblies. Manufactured to ABEC1 precision class, it offers a robust balance of performance and value for high-volume, precision-driven applications.
MF117zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| MF | Flanged Outer Ring | Simplifies mounting and axial location, provides secure housing fit. |
| 117 | Bore Size Code (7mm) | Specifies the critical inner diameter dimension. |
| zz | Shielded on Both Sides | Offers effective protection against dust and debris, retaining lubrication. |
Structural Features and Performance Benefits
- Flanged Design: The outer ring flange (12.2mm diameter) enables easy and precise axial positioning within a housing, reducing assembly time and cost.
- Shielded Protection: The non-contact stainless steel shields (zz) protect the bearing internals from particulate contamination while minimizing friction, contributing to a limiting speed of 43,000 rpm.
- High-Quality Materials: Constructed from chrome steel rings and balls with a stainless steel cage, ensuring durability, corrosion resistance, and stable operation.
- Optimized Internal Geometry: With 9 balls of 1.2mm diameter, the bearing is designed for smooth operation and efficient radial load capacity (87 lbf dynamic, 36 lbf static).
- Standard Internal Clearance (MC3): Provides an optimal fit for most general applications, ensuring minimal play and consistent performance.
MF117zz Bearing Typical Application Areas
The MF117zz is ideally suited for a wide range of small precision machinery and devices, including:
- Small DC Motors and Gear Motors
- Precision Instruments and Optical Encoders
- Office Automation Equipment (Printers, Scanners)
- Computer Cooling Fans and Spindle Drives
- Medical Devices and Laboratory Equipment
- Radio-Control Models and Drones
