LM8SUU Short Linear Ball Bearing – 8×15×17mm FAQ 's

Frequently asked questions about the LM8SUU Short Linear Ball Bearing – 8×15×17mm

The "UU" means the bearing has rubber contact seals on both ends (double sealed). Each "U" represents one sealed end, keeping dust and debris out and grease in.

The number in the model is the bore — the diameter of the shaft it runs on. An LM8UU fits an 8mm smooth rod, an LM10UU fits a 10mm rod, and so on. Match the bore to your existing linear shaft.

The "L" versions have a longer body with extra rows of balls. This spreads the load over a greater length, giving a higher load capacity and less rock or play on long, unsupported rails.

Yes. The LM8UU is the classic size used on RepRap and Prusa i3-style printers, and the range is widely used across CNC machines, laser cutters, plotters and general automation.

They arrive pre-greased and ready to use. For long life, keep the shaft clean and re-apply a light machine oil or grease periodically, especially in dusty environments.
