HD Y-Axis Nut Seat, Fits SainSmart Genmitsu 3018-PROVer Desktop CNC Router

Why do we offer this product? It is common knowledge within the 3018 CNC user circles that the OEM injection molded nylon, Anti-backlash Y-Axis nut seat, is prone to failure (we are not talking about wear, as all anti-backlash nuts wear and will require periodic replacement).  The failure we are referring to specifically is the separation of the 10mm diameter brass anti-backlash nut from the nylon nut seat itself.  OEM units, made in China feature a press-fit and sometimes glued (when the fit isn’t as snug as the assembler had hoped for) arrangement.  Unfortunately the OE product, assembled in this manner is highly prone to failure which will make your machine inoperable and ruin your job.  We’ve made great strides in improving the OEM style anti-backlash nut-seat and the improved product is available by clicking here.  What cannot be changed about the OEM type nut is the press-fit nature of the brass anti-backlash nut itself, that is why we originally came up with the HD Y-Axis Nut Seat design, that offers a simple bolt-in configuration, for ease of replacement with common hand tools.

This is similar to the upgraded nut-seat that has been shipping with our NCPRO brand 3018-PRO machines!  We now offer this user-serviceable HD Y-Axis Nut Seat in a version specific to the SainSmart Genmitsu 3018-PROVer (or other clone machines that feature similar 21.5mm table offset).   Click here for the HD unit designed for 3018-PRO machines with 22.5mm offset.

Because we care about our community.  Our nut-seats are both designed and manufactured in-house, in Colorado U.S.A., exclusively using clean renewable solar energy.  We manufacture our products using a high resolution FDM process and PET-G plastic.  Purchasing NCPRO brand products such as this, fuels future innovation, supports domestic workers and independent small business.  Our staff and our community thank you for your support!

Fitment Notes: This V2 Y-Axis Nut Seat has been modified to properly fit the SainSmart Genmitsu 3018PROVer.  Prior to purchasing you should verify that your machine uses an 8mm T8 type lead screw with 2mm pitch and 4mm lead.  Also verify the offset distance from the bottom of your Y-Axis table to the center of the lead screw – this should be 21.5mm.  NCPRO brand 1610, 1810, and 3018-PRO CNC routers feature a 22.5mm offset – CLICK HERE for our Y-Axis Nut Seat product that is specific to our 3018-PRO.
