Description
The LM3UU 3mm Linear Ball Bearing is a compact linear motion component designed to support smooth movement along a compatible 3mm shaft or guide rod. It is suitable for applications requiring controlled linear travel, including 3D printers, CNC machines, engraving equipment, and custom mechanical projects.
Constructed from carbon chromium bearing steel, this bearing is designed for use in compatible linear motion assemblies. Its small dimensions make it a practical choice for compact equipment where space is limited.
For optimal performance, appropriate lubrication may be required, and a running-in period may be necessary depending on the application. Before installation, check the shaft diameter and bearing dimensions to ensure compatibility.
