LM10UU Linear Motion Slider Linear Bushing, Bearing for 10mm Shaft

LM10UU Linear Bushing — Linear Motion Ball Bearing for 10mm Shaft

The LM10UU is a linear motion ball bushing designed to slide smoothly along a 10mm precision shaft, converting rotary ball-bearing technology into linear travel. Internally, recirculating ball bearings run along the shaft surface inside the bushing, allowing smooth, low-friction linear movement with minimal play — essential for accurate positioning in motion-control systems.

It’s a widely used linear bearing in 3D printing and CNC builds, commonly paired with 10mm smooth rods on the X, Y, or Z axis, and is a standard component in DIY robotics and automation projects needing slightly higher load capacity than the smaller 8mm size.

Product Details

Features

• Smooth, low-friction linear travel along a 10mm precision shaft
• Recirculating ball design for consistent, repeatable motion
• Compact cylindrical housing, easy to mount in standard linear bearing blocks
• Widely compatible — standard size used across most 3D printers and CNC machines
• Low-maintenance operation with proper lubrication and clean shaft surface

Applications

• 3D printer X/Y/Z axis linear motion (paired with 10mm smooth rod)
• CNC machines and engraving tools
• Robotics arms and sliding mechanisms
• General linear motion and automation projects

Usage Note

• Requires a smooth (unthreaded), precision-ground 10mm shaft for proper operation — not compatible with threaded rod or rough-surfaced shafts
• Keep the shaft clean and lightly lubricated for smooth, long-lasting performance

Package Includes

• 1 x LM10UU Linear Bushing
