LM6UU linear bearing for 6 mm smooth shaft

The LM6UU linear bearing is a ball bushing designed to guide linear movement along 6 mm smooth shafts. Its compact dimensions make it suitable for RepRap 3D printers, small CNC machines, automation equipment and custom linear motion projects.

The recirculating balls provide guided movement with low friction. It can be used in new assemblies or as a replacement for another LM6UU, provided that the bearing dimensions and housing specifications match.

Main features

• Reference: LM6UU.
• Designed for 6 mm smooth shafts.
• Compact format for linear motion systems.
• Suitable for 3D printers, light CNC machines and automation projects.

Nominal dimensions

• Inner diameter: 6 mm.
• Outer diameter: 12 mm.
• Length: 19 mm.

Compatibility and installation

It is dimensionally compatible with 6 mm smooth shafts and housings designed for LM6UU bearings with a 12 mm outer diameter and a length of 19 mm. The 12 mm outer diameter should not be confused with the shaft diameter, which must be 6 mm.

When replacing an existing bearing, check the shaft diameter, housing dimensions and available installation space. Tolerances and fit may vary slightly depending on the manufacturer or production batch.

Other available sizes

For different shaft diameters, see the LM8UU linear bearing for 8 mm shafts or the LM10UU linear bearing for 10 mm smooth shafts. These models are not dimensionally interchangeable with the LM6UU.
