MF105 2rs Bearing Product Overview & Core Advantages
The MF105 2RS is a metric miniature ball bearing designed for precision applications requiring compact dimensions and reliable performance. This single row deep groove ball bearing features integral rubber seals (2RS) on both sides, providing excellent protection against contamination while retaining lubricant. Its design is optimized to handle primarily radial loads and is characterized by its small bore diameter (5 mm), outside diameter (10 mm), and width (4 mm). Manufactured from chrome steel with an ABEC1 tolerance class, it offers a cost-effective solution for high-speed operation up to 50,000 rpm, making it ideal for applications demanding high rotational accuracy and long service life.
MF105 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit/Feature |
|---|---|---|
| MF105 | Basic bearing designation indicating a metric, flanged miniature bearing with specific dimensions (5x10x4 mm). | Defines the core bearing size and the presence of an outer ring flange for simplified mounting and axial location. |
| 2RS | Contact Rubber Seals on both sides of the bearing. | Provides effective sealing against dust, moisture, and other contaminants, while retaining lubricant for extended service life and reduced maintenance. |
MF105 2rs Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: The optimized raceway geometry enables smooth operation and efficient handling of radial loads. The single-row construction ensures a compact bearing width for space-constrained applications.
- Integrated Flange & Sealed Construction: The outer ring flange (flange outer diameter: 11.6 mm) facilitates easy and precise mounting, eliminating the need for complex housing designs. The Nitrile rubber (2RS) seals offer superior protection, making the bearing suitable for environments where contamination is a concern.
- High-Speed Capability: With a limiting speed of 50,000 rpm and a stainless steel cage to guide the balls accurately, this bearing is engineered for high-speed applications, minimizing friction and heat generation.
- Precision and Rigidity: Manufactured to ABEC1 precision class standards with tight dimensional tolerances, the bearing provides consistent performance and high running accuracy. The specified radial internal clearance (MC3 group) ensures optimal fit and performance in various operating conditions.
MF105 2rs Bearing Typical Application Areas
- Small Electric Motors: Ideal for spindle and rotor support in miniature DC motors, stepper motors, and fans.
- Precision Instruments & Medical Devices: Used in optical encoders, scanners, dental handpieces, and laboratory equipment requiring quiet operation and high reliability.
- Office Automation & Robotics: Suitable for paper feed rollers in printers, copiers, and joints in small robotic arms.
- Consumer Electronics: Commonly found in computer cooling fans, drones, and power tools.
