This version is design for the following Misumi leadscrew and resin nut.
Leadscrew Nut: MTSRN10
The stainless steel leadscrew and resin nut makes for a lub free configuration. Pairing them with the Misumi LMUW-MX10 self lubricating linear bearing makes for a lubrication free setup.
You can also use either a LM10LUU or 2 LM10UU with these x-ends. I opt for the Misumi LMUW-MX10 because I want to make my printer as maintenance free as possible.
