F688ZZ Flanged Ball Bearing

F688ZZ Flanged Ball Bearing is a high-precision, deep groove ball bearing with double metal shields and an integrated flange, offering both axial and radial load handling capabilities. Its 8mm inner diameter and 16mm outer diameter make it ideal for small machinery, robotics, 3D printers, and electric motors, where axial positioning and compact design are essential.

Key Features:

• Flanged Design: Built-in flange for secure axial positioning and simplified installation.
• Double Shielded (ZZ): Metal shields on both sides prevent contamination and retain lubricant.
• Low Friction: Enables smooth, quiet rotation under load.
• High Precision: Tight tolerances ensure consistent performance in demanding setups.
• Corrosion Resistant: Chrome steel construction resists wear and rust.
