We have phased out MXL pulleys. Please consider GT2 belts and pulleys for your application.
A high-quality belt pulley for MXL belt (0.08 inch pitch, or 2.032 mm) up to 6.35 mm (0.25 inch) wide, made in USA. The pulley has a 6.35 mm (1/4 inch) diameter bore, suitable for most NEMA23 stepper motors. It is the same type of pulley used in the eShapeOko and ShapeOko 1 kits, except with a larger bore, so it's ideal for a NEMA23 upgrade of a ShapeOko 1 or eShapeOko CNC milling machine. It has a single #6-32 grub screw with a 1/16 inch hex socket. We'll throw in a 1/16 inch Allen key to save you the hassle of finding imperial-size tools in Europe.
Material: glass-filled polycarbonate, aluminium alloy, steel.
Part number: EM-BP6 (replacing EM-BP5 for the eShapeOko, MSK01-09 for the ShapeOko 1, both of which are 5 mm bore pulleys).
