SMF126 2rs Bearing Product Overview & Core Advantages
The SMF126 2RS is a miniature sealed ball bearing engineered for precision applications requiring compact design and reliable performance. This single row deep groove ball bearing is constructed entirely from stainless steel, providing excellent corrosion resistance. Its key advantage lies in its integrated rubber seals (2RS), which effectively retain lubrication and exclude contaminants, making it suitable for applications demanding low maintenance and long service life. With a metric bore diameter of 6mm and a compact cross-section, it is an ideal solution for space-constrained assemblies.
SMF126 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| SMF126 | Basic bearing designation indicating a flanged bearing with a 6mm bore and 12mm outside diameter. | Defines the core dimensions and the presence of a mounting flange for simplified axial location. |
| 2RS | Designates contact rubber seals on both sides of the bearing. | Provides superior protection against dust, moisture, and other contaminants, ensuring long-term reliability and reduced maintenance. |
SMF126 2rs Bearing Structural Features & Performance Benefits
- Robust Construction & Corrosion Resistance: Manufactured from stainless steel rings, balls, and cage, this bearing offers excellent resistance to rust and corrosion, making it suitable for harsh environments and washdown applications.
- Effective Sealing: The Nitrile Rubber (NBR) contact seals (2RS) provide a high degree of protection, retaining lubricant and effectively excluding contaminants. This design is crucial for maintaining performance and extending bearing life.
- Radial Load Capacity & High-Speed Operation: The deep groove raceway and 8 precision balls are optimized to handle radial dynamic loads up to 123 lbf and achieve a limiting speed of 38,700 rpm.
- Simplified Mounting: The integrated flange (13.6mm outer diameter) allows for easy axial positioning and secure mounting within a housing, simplifying assembly and reducing component count.
- Precision & Consistency: Built to ABEC1 tolerance class with a controlled MC3 radial internal clearance (0.002mm to 0.013mm), ensuring smooth and consistent operation.
SMF126 2rs Bearing Typical Application Areas
The SMF126 2RS is ideally suited for a wide range of miniature and precision applications, including:
- Small Electric Motors: Used in drones, RC models, and small cooling fans.
- Precision Instruments & Medical Devices: Suitable for surgical tools, optical encoders, and laboratory equipment.
- Office Automation & Consumer Electronics: Found in printers, scanners, and small gearboxes.
- Food Processing & Packaging Equipment: Its stainless steel construction and effective sealing make it suitable for washdown environments.
