F685zz Bearing Product Overview & Core Advantages
The F685zz is a miniature deep groove ball bearing designed for compact applications requiring reliable performance. This metric single row bearing features integral shielded protection on both sides, effectively containing lubricant and excluding contaminants. Its primary advantages include a compact flanged design for simplified mounting and axial location, a high-quality stainless steel cage for stable operation, and a robust construction using chrome steel rings and balls for durability. Engineered for radial load applications, it offers a balanced combination of high limiting speed and long service life in a minimal footprint.

| Suffix | Technical Meaning |
|---|---|
| F | Flanged outer ring for easy mounting and positioning. |
| zz | Non-contact steel shields on both sides for effective contaminant exclusion and lubricant retention. |
F685zz Bearing Structural Features & Performance Benefits
- Flanged Design: The outer ring flange (Ø12.5mm) simplifies installation and provides a positive axial location within a housing, enhancing assembly accuracy and reliability.
- Shielded Protection: The double-shielded (zz) construction protects the 8 precision balls and internal components from dust and debris while retaining lubricant, contributing to low maintenance requirements.
- Stable Cage & Precision: The stainless steel cage ensures smooth ball guidance and stable operation at high speeds. Manufactured to ABEC1 tolerance class with a controlled MC3 radial internal clearance, it delivers consistent and quiet running performance.
- High-Speed Capability: The optimized internal geometry and lightweight cage contribute to a high limiting speed of 45,000 rpm, making it suitable for demanding, high-RPM applications.
- Material Integrity: Constructed from chrome steel for rings and balls, the bearing offers excellent wear resistance and fatigue life, supporting its dynamic load rating of 137 lbf and static load rating of 51 lbf.
F685zz Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in small DC motors, stepper motors, and brushless fans.
- Office Automation Equipment: Commonly used in printers, scanners, and copiers.
- Medical Devices: Suitable for small pumps, dental handpieces, and laboratory instrumentation.
- Robotics & RC Models: Used in joint assemblies, gearboxes, and drive wheels for their compact size and reliability.
- Instrumentation & Measurement Devices: Provides precise rotational support in encoders, sensors, and gauges.
