MF95zz Bearing Product Overview & Core Advantages
The MF95zz is a miniature metric ball bearing engineered for compact applications demanding reliable performance. As a single row deep groove ball bearing, it is optimally designed to support primarily radial loads. Its shielded (ZZ) construction provides effective protection against contamination while retaining lubricant, making it a robust and durable choice for small-scale precision mechanisms. This bearing is characterized by its small dimensions (5mm bore, 9mm OD) and low weight, offering a high-performance solution in a minimal footprint.
MF95zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| MF95 | The base bearing designation, indicating a specific series with a 5mm bore and 9mm outside diameter. |
| zz | Signifies that the bearing is equipped with non-contact shields on both sides. This provides protection from large particulate contaminants and helps retain lubricant, contributing to a maintenance-free design. |
MF95zz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a width of just 3mm and a weight of 0.66g, this bearing is ideal for applications where space and weight are critical constraints.
- Shielded for Contamination Resistance: The stainless steel ZZ shields offer a first line of defense against dust and debris, enhancing bearing service life and reliability without significantly increasing rotational torque.
- Precision & Smooth Operation: Manufactured to ABEC1 tolerance class and featuring a stainless steel cage, this bearing ensures consistent and smooth running, which is crucial for precision instruments.
- Optimized Internal Clearance: The standard MC3 radial internal clearance (0.002mm to 0.013mm) is suitable for a wide range of operating conditions, providing a balance between noise, temperature, and load capacity.
- High-Quality Materials: Constructed from chrome steel rings and balls, the bearing provides excellent durability and wear resistance.
MF95zz Bearing Typical Application Areas
This miniature deep groove ball bearing is commonly specified in:
- Small Precision Motors (e.g., stepper motors, DC micromotors)
- Office Automation Equipment (printers, scanners, copiers)
- Medical Devices and Instrumentation
- Robotics and RC Models
- Computer Cooling Fans and small gearboxes
