LM8LUU 8mm Bushing Longer Linear Ball Bearing
This LM8LUU 8mm Bushing Longer Linear Ball Bearing is a longer version of our standard LM8LUU linear slide bush for 8mm hardened steel shafts.
The Bearings gives you very precise, safe and reliable linear motion system. Such linear motion bearings are mostly used in 3D printers and CNC (Computer Numerical Control) machines. This Linear Ball Bearing can provide low friction motion along a single axis, hence find a wide range of applications in DIY and robotics prototyping.
This LM8LUU 8mm Bushing Longer Linear Ball Bearing closed type ball bushing has an 8mm bore and 15mm outer diameter is suitable for use in a mounted slide unit to carry components.
Balls in the cage loop run along a smooth ball guide surface to ensure low noise even in the high-speed operation.
Since Linear Motion bearings slide along the round shaft, for the reliable and smooth motion the shaft must be lubricated. The quality of the shaft directly influences the quality of linear motion we get. So, using chrome plated and hardened shaft may serve beneficial.
The linear motion bearings is available in more varieties as below
LM6LUU
LM10LUU
LM12LUU
LM16LUU
Features:
- Linear bearing ball cage, hardened coat of both ends ring.
- Made of carbon chromium bearing steel, safe and reliable.
- Ball in the cage loop to run a smooth ball guide surface to ensure stability even if high-speed.

Frequently Asked Questions
What’s the main advantage of LM8LUU over a standard LM8UU bearing?
The LM8LUU has a longer 25 mm body compared to the typical 22 mm of an LM8UU, offering greater contact length with the shaft for improved load distribution and stability in extended travel applications.
Can this bearing handle axial loads as well as radial loads?
LM8LUU is primarily designed for radial loads along the shaft, but its precision ball arrangement provides limited axial load capacity. For heavy axial forces, consider using dedicated thrust bearings.
What shaft specification is recommended for optimal performance?
Use a hardened steel shaft with a ground 8 mm diameter and surface roughness below Ra0.4. This ensures minimal wear on the chromium steel casing and maintains low-friction linear motion.
