(1 customer review)

Original price was: $20.00.Current price is: $15.00.

The NCPRO Heavy Duty Y-Axis Anti-Backlash Nut Seat is an updated offering, that replaces the OE style press-fit brass anti-backlash nut and nut-seat, with a more durable and widely available user-serviceable anti-backlash nut.  The HD Y-Axis Anti-Backlash Nut Seat is completely bolt in and field serviceable with common tools and without the need for access to an arbor press.  Our nut seat is manufactured in the USA to exacting tolerances, from impact-resistant PET-G plastic, using high-resolution FDM processes.  We have combined our HD Y-Axis Nut Seat with a long wearing, high-quality brass anti-backlash nut – a perfect fit to your NCPRO brand 1610, 1810 or 3018-PRO CNC Router.  This item requires assembly.

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 the same upgraded nut that has been shipping with our NCPRO brand 3018-PRO machines!  We now offer this user-serviceable HD Y-Axis Nut Seat in two versions, one that we’ve included with our own 3018-PRO machines and another to upgrade the SainSmart Genmitsu 3018-PROVer (or other clone machines that feature similar table offset).   Between these two models we think we have most of the genuine 3018 and cloned hardware covered, but do follow the guidance below to measure your machine prior to ordering.

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 designed to fit NCPRO brand 1810 and 3018-PRO desktop CNC Routers.  This product may fit other 3018 ‘clones’.  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 22.5mm to be compatible with our product.  SainSmart Genmitsu 3018-PROVer CNC routers feature a 21.5mm offset – CLICK HERE for our Y-Axis Nut Seat product that is specific to the 3018-PROVer.

    I’m impressed with the difference this upgrade makes compared to the stock nut. No more rattle or squeaking, and overall seems to be smoother.

    One caveat if you’re using one of the MDF beds from SainSmart is that the mounting holes are different than the stock seat, so the holes on the bed won’t align. I ended up using some short wood screws to mount the seat slightly offset from the original location.

      Thanks for your feedback Ryan, you bring up a good point with regard to SainSmart’s MDF bed – the HD Y-Axis nut has a bit wider spacing on the mount than say our upgraded OE style nut. I’ll bring this up with the CAD guys and see if we can’t accommodate the OE spacing in future builds. Thank you for taking the time to comment.
