MF63 2rs Bearing Product Overview & Core Advantages
The MF63 2RS is a miniature sealed deep groove ball bearing designed for applications requiring compact dimensions and reliable performance. This single row ball bearing excels in handling radial loads and is characterized by its sealed construction with nitrile rubber contact seals (2RS) on both sides, providing excellent protection against contamination. Its small bore diameter of 3mm and lightweight design at 0.26g make it ideal for space-constrained, high-speed applications such as small precision instruments and miniature motors, offering a dependable solution for demanding operational environments.
MF63 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| MF63 | The base bearing designation, indicating a specific series of miniature deep groove ball bearings with a 3mm bore, 6mm OD, and 2.5mm width. |
| 2RS | Denotes double rubber contact seals on both sides. This provides superior protection against dust, moisture, and other contaminants, retaining lubricant effectively for extended service life. |
MF63 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing & Contamination Resistance: The double nitrile rubber contact seals (2RS) ensure a high degree of protection, making the bearing suitable for environments where contamination is a concern. This design also helps retain the factory-applied lubricant.
- High-Speed Capability: Featuring a stainless steel cage and optimized internal geometry, this bearing supports a limiting speed of 71,000 rpm, making it a capable high-speed bearing for miniature applications.
- Precision & Reliability: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group: 0.002mm to 0.013mm), this precision bearing ensures smooth and consistent operation.
- Durable Material Construction: The rings and balls are made from chrome steel, providing high hardness and wear resistance, while the stainless steel cage offers strength and corrosion resistance.
