12mm x 450mm Linear Rails, Pair (tapped M5)


Toss those flexible rails in favor of our oversized Y-Axis rails, custom created by NCPRO for your 3018-Pro CNC. These NCPRO 12mm x 450mm Optical Axis Linear Rails feature a durable hard chrome treatment and are cut to 450mm overall length, chamfered and center tapped on both end, with stock M5 threads. The rails are a drop in replacement for the 3018-PRO CNC Router with extended Y-Axis – complete the upgrade with our custom low-profile 12mm linear bearings. Sold in package of 2 rails.

Additional Details

Note: SainSmart brand 3018-PROVer machines (the blue anodized version) feature a non-standard length (longer) linear rail configuration that nest into the front and side plates of the PROVer type machine. Our rails are designed to fit the 3018-PRO using the standard lengths indicated in our product specifications and are not machined to nest within the X and Y end-plates of the SainSmart PROVer equipment. That said, our rails still work great with the SainSmart PROVer 3018 machine and will sit on top of the 10mm recess within the X and Y gantry plates.
