MF126 2rs Bearing Product Overview & Core Advantages
The MF126 2RS is a metric miniature deep groove ball bearing designed for compact applications requiring reliable performance. This single row bearing features integral rubber seals (2RS) on both sides, providing excellent protection against contaminants and retaining lubricant. Engineered with chrome steel rings and balls combined with a stainless steel cage, it delivers dependable operation and extended service life. Its primary advantage lies in its ability to handle radial loads efficiently within a constrained space, making it ideal for applications where size and reliability are critical factors.
MF126 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| MF126 | Basic bearing designation, indicating a specific size series with a 6mm bore, 12mm OD, and 4mm width. |
| 2RS | Contact Rubber Seals on both sides. This provides superior sealing effectiveness compared to non-contact shields, protecting against dust and moisture while retaining lubricant for long-term performance. |
MF126 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing for Contaminated Environments: The double-sided Nitrile Rubber (NBR) seals (2RS) are in light contact with the inner ring, effectively excluding contaminants like dust and moisture. This design significantly enhances bearing life in demanding conditions and retains lubricant, supporting the limiting speed of 43,000 rpm.
- Stable Cage for Smooth Operation: The stainless steel cage precisely guides the 8 balls, ensuring smooth rotation and stability at high speeds, contributing to low noise and vibration levels.
- Precision and Load Capacity: Manufactured to ABEC1 tolerance class with a MC3 radial internal clearance (0.002mm to 0.013mm), this bearing offers consistent performance. It provides a dynamic load rating of 137 lbf and a static load rating of 53 lbf, suitable for various radial load applications.
- Wide Operating Temperature Range: The standard lubrication and material selection allow for a functional temperature range from -30°C to 110°C, accommodating many industrial environments.
MF126 2rs Bearing Typical Application Areas
This sealed miniature bearing is commonly found in:
- Small Precision Motors (e.g., in drones, hand tools)
- Office Automation Equipment (e.g., printers, scanners)
- Medical Devices and Instrumentation
- Computer Cooling Fans
