Long Linear Bearings LM-L are excellent professional types of bearings used in 3D printers and other CNC equipment.
For CNC machines, 3D printers and laser engravers, linear bearings of the following sizes are often used:
LM6LUU, LM8LUU, LM10LUU, LM12LUU, LM13LUU, LM16LUU, LM20LUU, LM25LUU, LM30LUU, LM40LUU, LM50LUU.
In the table you will definitely find the dimensions of the long bearing LM8LUU – a common bearing among those who like to assemble a 3D printer with their own hands.
