MF62 2rs Bearing Product Overview & Core Advantages
The MF62 2RS is a miniature deep groove ball bearing engineered for applications demanding compact size and reliable performance. This sealed bearing is designed to primarily handle radial loads and is characterized by its low friction and smooth operation. Its compact dimensions (2mm bore, 6mm OD) make it an ideal solution for high-precision and space-constrained assemblies where consistent performance is critical. The integrated seals and pre-lubrication ensure long-term reliability, making it a robust choice for various industrial and electronic applications.

MF62 2rs Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from chrome steel rings and balls with a stainless steel cage, this bearing offers excellent durability and corrosion resistance.
- Effective Sealing: The Nitrile Rubber (NBR) contact seals (2RS) effectively shield the internal components from dust, moisture, and other contaminants, making it suitable for demanding environments.
- Optimized Internal Geometry: The deep groove raceway and six precision balls enable efficient handling of radial dynamic loads (63 lbf) and moderate axial loads in both directions.
- Precision & Smooth Operation: Built to ABEC1 tolerance class with a controlled radial internal clearance (MC3: 0.002mm to 0.013mm), ensuring smooth running and low vibration.
- Compact & Lightweight: With a total weight of only 0.34 grams, it minimizes inertia and is perfect for high-speed, lightweight mechanisms.
MF62 2rs Bearing Typical Application Areas
This miniature bearing is widely used in applications requiring small bearing dimensions and reliable operation, including:
- Small Precision Motors (e.g., stepper motors, coreless motors)
- Office Automation Equipment (e.g., printers, scanners, copiers)
- Medical Devices and Instrumentation
- Robotics and RC Models
- Optical Encoders and Sensitive Measuring Instruments
