SMF95 2rs Bearing Product Overview & Core Advantages
The SMF95 2RS is a metric miniature ball bearing engineered for precision applications requiring compact dimensions and reliable performance. This single row deep groove ball bearing features integral rubber seals (2RS) for effective contamination protection. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its primary advantages include a compact 5mm bore design, suitability for radial loads, and robust construction for high reliability in demanding miniature assemblies.
SMF95 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SMF95 | Indicates the bearing series and core dimensions: 5mm bore, 9mm outer diameter. |
| 2RS | Signifies contact rubber seals on both sides. This provides superior sealing effectiveness compared to non-contact shields, protecting against dust and moisture, albeit with a slight trade-off in maximum speed. |
SMF95 2rs Bearing Structural Features & Performance Benefits
- Compact & Robust Design: With dimensions of just 5x9x3 mm, this bearing is ideal for space-constrained applications. The single row deep groove raceway is optimized for handling radial dynamic loads up to 74 lbf.
- Enhanced Sealing & Protection: The Nitrile rubber (NBR) seals (2RS) provide excellent protection against contaminants and moisture, extending bearing life in challenging environments. The seals also help retain lubricant.
- Corrosion Resistance: Manufactured from stainless steel for rings, balls, and cage, this bearing is suitable for applications exposed to humidity, water, or certain chemicals, ensuring long-term performance.
- Precision Performance: Manufactured to ABEC1 tolerance class with a standard radial internal clearance (MC3 group), ensuring consistent and smooth operation for general precision requirements.
SMF95 2rs Bearing Typical Application Areas
This bearing is commonly specified in:
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Medical Devices & Instrumentation: Used in surgical tools, dental handpieces, and analytical instruments where compact size, reliability, and corrosion resistance are critical.
- Office Automation Equipment: Suitable for paper feed rollers, scanners, and small printers.
- Robotics & RC Models: Provides precise motion control in small joints, gears, and drive systems.
- Precision Mechanical Assemblies: Used in encoders, gauges, and other devices requiring miniature, high-quality rotational components.
