MF137 2rs Bearing Product Overview & Core Advantages
The MF137 2rs is a miniature sealed ball bearing engineered for precision applications requiring reliable performance in compact spaces. This single row deep groove ball bearing excels in handling radial loads and is characterized by its integral rubber seal (2RS) which provides superior protection against contaminants. Its ABEC1 precision class and stainless steel cage ensure smooth operation and consistent performance, making it an ideal choice for applications demanding high reliability and long service life in demanding environments.
MF137 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| MF137 | Standard bearing designation indicating specific bearing dimensions (7mm bore, 13mm OD, 4mm width). | Defines the core size and fit for design integration. |
| 2RS | Bearing is equipped with contact rubber seals on both sides. | Provides excellent protection against dust, moisture, and other contaminants, enhancing bearing life and reliability. |
MF137 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing: The dual Nitrile rubber (2RS) seals effectively retain lubricant and exclude harmful particles, making the bearing suitable for dirty or humid environments and contributing to its low maintenance requirements.
- Precision & Smooth Operation: Manufactured to ABEC1 tolerance class with a stainless steel cage, this bearing ensures minimal vibration and noise, which is critical for sensitive and high-speed applications.
- Optimized Internal Geometry: The deep groove raceway and complement of 12 precision balls enable efficient handling of radial dynamic loads up to 104 lbf.
- Wide Temperature Range: Constructed from chrome steel rings and balls, the bearing operates reliably within a temperature range of -30°C to 110°C.
MF137 2rs Bearing Typical Application Areas
This versatile miniature bearing is ideally suited for:
- Small Precision Motors (e.g., in drones, RC models, and cooling fans)
- Office Automation Equipment (printers, scanners, copiers)
- Medical Devices and Instrumentation
- Textile Machinery guides and tensioners
- Low-Power Gearboxes and Actuators
