MF104 2rs Bearing Product Overview & Core Advantages
The MF104 2RS is a metric single row deep groove ball bearing designed for exceptional performance in compact applications. This sealed bearing excels at handling radial loads and is engineered for high reliability. Its compact dimensions (4mm bore, 10mm OD) and integral rubber seals (2RS) make it an ideal choice for applications requiring protection from contaminants and minimal maintenance. Manufactured to ABEC1 precision tolerances, it delivers consistent performance for demanding B2B and industrial uses.
MF104 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| MF104 | Basic bearing designation indicating specific dimensions (4mm bore, 10mm OD, 4mm width) | Standardized sizing for easy replacement and system design |
| 2RS | Contact rubber seals on both sides | Superior contamination protection and lubricant retention |
MF104 2rs Bearing Structural Features & Performance Benefits
- Deep Groove Geometry & Single Row Design: Optimized for high radial load capacity while accommodating moderate axial loads in both directions.
- Stainless Steel Cage: Ensures dimensional stability and reliable ball guidance, contributing to smooth operation and extended service life.
- Double Rubber Seals (2RS): Provide excellent sealing effectiveness against dust, moisture, and other contaminants, making the bearing suitable for harsh environments. This design also effectively retains lubricant, promoting long-term performance.
- Chrome Steel Construction: Rings and balls made from chrome steel offer high hardness, wear resistance, and durability, supporting the dynamic load rating of 136 lbf.
- Precision Engineering: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3: 0.002mm to 0.013mm) ensures consistent operation, low noise, and minimal vibration.
MF104 2rs Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Office Automation Equipment: Used in printers, scanners, and copiers for paper feed rollers and scanner carriages.
- Medical Devices: Suitable for small pumps, dental handpieces, and laboratory equipment requiring reliable, compact bearings.
- Instrumentation and Control Systems: Applied in encoders, sensors, and small gearboxes where precision and reliability are critical.
- Consumer Electronics: Found in cooling fans, small drones, and various portable devices.
