MF82x 2rs Bearing Product Overview & Core Advantages
The MF82x 2rs is a metric miniature ball bearing featuring a single row design with integral rubber seals (2RS). Engineered for applications requiring compact dimensions and reliable performance, this bearing is designed to handle primarily radial loads. Its flanged outer ring provides secure mounting and accurate axial location, making it an ideal choice for high-precision assemblies where space is limited and operational reliability is critical.
MF82x 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| MF82x | Series designation indicating a miniature flanged bearing with specific bore and outside diameter dimensions. |
| 2RS | Bearing is equipped with contact rubber seals on both sides, providing effective protection against contaminants. |
MF82x 2rs Bearing Structural Features & Performance Benefits
- Compact & Space-Saving Design: With dimensions of just 2.5mm (bore) x 8mm (OD) x 2.5mm (width), this bearing is optimized for miniature applications.
- Enhanced Contamination Protection: The double rubber seals (2RS) effectively shield the bearing interior from dust, moisture, and other contaminants, extending service life.
- Secure Mounting & Positioning: The flanged outer ring simplifies installation and ensures precise axial location within the housing.
- Precision Performance: Manufactured to ABEC1 tolerance class with MC3 radial internal clearance (0.002mm to 0.013mm), ensuring consistent and smooth operation.
- High-Speed Capability: The stainless steel cage and optimized design contribute to a high limiting speed of 71,000 rpm.
- Robust Load Capacity: Chrome steel construction provides a dynamic load rating of 40 lbf and static load rating of 15 lbf for reliable performance under radial loads.
MF82x 2rs Bearing Typical Application Areas
- Small Precision Motors: Ideal for miniature DC motors, stepper motors, and coreless motors.
- Medical Devices: Used in surgical hand tools, dental equipment, and diagnostic instruments.
- Office Automation: Suitable for printers, scanners, and copiers where compact, reliable bearings are required.
- Robotics & Automation: Applied in small robotic joints, actuators, and precision positioning systems.
