F686 2rs Bearing Product Overview & Core Advantages
The F686 2RS is a miniature sealed ball bearing designed for compact applications requiring reliable performance. This single row deep groove ball bearing features integral rubber seals (2RS) for effective contamination protection. Its metric dimensions (6mm bore, 13mm OD) and flanged design (15mm flange OD) facilitate precise mounting and positioning in confined spaces. Engineered with chrome steel rings and balls, it offers a robust solution for radial loads and moderate operating speeds, making it ideal for applications demanding compact size and maintenance-free operation.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| F686 | Basic bearing designation indicating the bearing size and series. |
| 2RS | Bearing is equipped with contact rubber seals on both sides. The "RS" suffix denotes a Nitrile Rubber (NBR) seal, providing excellent protection against dust and moisture. |
F686 2rs Bearing Structural Features & Performance Benefits
- Robust Construction & High Reliability: The bearing utilizes chrome steel for both rings and balls, coupled with a stainless steel cage. This material combination ensures high durability, corrosion resistance, and consistent performance under radial dynamic loads up to 207 lbf.
- Effective Sealing & Contamination Protection: The double-sided 2RS contact seals are highly effective at retaining lubricant and excluding contaminants. This design significantly enhances bearing life in dusty or humid environments and supports its maintenance-free characteristic.
- Flanged Design for Easy Installation: The integrated flange (15mm OD) simplifies axial location and mounting, reducing assembly time and cost. This is particularly beneficial in miniature applications where precise positioning is critical.
- Precision & Smooth Operation: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 / 0.002mm to 0.013mm), the bearing ensures smooth, low-vibration, and low-noise operation, suitable for sensitive equipment.
F686 2rs Bearing Typical Application Areas
- Small Electric Motors: Ideal for use in miniature DC motors, stepper motors, and fan motors.
- Precision Instruments & Medical Devices: Suitable for small gearboxes, optical encoders, and handheld medical tools.
- Office Automation Equipment: Commonly used in printers, scanners, and copiers.
- Robotics & Automation: Applied in small robotic joints, actuators, and conveyor system guides.
- Consumer Electronics: Found in small appliances, drones, and computer peripherals.
