623ZZ Ball Bearing 3×10×4 mm for 3D Printers and Compact Mechanisms

Measuring 3×10×4 mm, this 623ZZ ball bearing is designed to provide smooth and accurate rotation in compact mechanical assemblies. Metal shields on both sides help protect the rolling elements from dust and debris, ensuring reliable operation in everyday applications.

This rolling bearing is primarily used on the X and Y axes of many FDM 3D printers, where it helps reduce friction in idler pulleys, belt tensioners and other moving assemblies. Its standardized dimensions also make it suitable for a wide range of compact mechanical and DIY engineering projects.
