F682x Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With an outer diameter of just 6 mm and a weight of only 0.24 grams, this bearing is engineered for applications with severe space and weight constraints.
- High-Speed Capability: The combination of a stainless steel cage and optimized internal geometry enables a limiting speed of 71,000 rpm, making it suitable for high-speed spindles and miniature motors.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group: 0.002mm to 0.013mm), ensuring smooth, low-vibration, and precise rotation.
- Robust Load Capacity: Despite its miniature size, it offers a dynamic load rating of 40 lbf and a static load rating of 13 lbf, providing reliable performance under radial loads.
- Material Integrity: Constructed from chrome steel rings and balls for high wear resistance and a stainless steel cage for enhanced corrosion resistance and cage stability.
F682x Bearing Typical Application Areas
- Precision Instruments: Optical encoders, gauges, and laboratory equipment.
- Small Motors & Spindles: Miniature DC motors, dental handpieces, and high-speed spindles.
- Office Automation: Printers, scanners, and copiers.
- Medical Devices: Surgical tools and diagnostic equipment requiring miniature, reliable components.
