3018-PRO CNC | Rigid 12mm Y-Axis Linear Rail Upgrade (290mm)

(1 customer review)

From: Original price was: $55.00.Current price is: $40.00.

Y-Axis like a trampoline?  We have the fix. 
What this bolt on upgrade does:

Our new 82mm Tandem Linear Pillow Block Slides* improve Y-Axis travel, adding a full 29 mm of usable range (a great way to account for lost travel due to the installation of limit switches). Additionally our 82mm Tandem Slides provide better alignment of the Y-Axis linear bearings – which can help average out small spoil board errors (that cause linear bearings to bind). This is a great upgrade for improving the function and precision of your 3018-PRO CNC router.

Additional Details

Our Y-Axis Linear Rod and Extended Travel Bearing Block Upgrade both reduces flex in your Y-Axis and adds more Y-axis travel (see notes).  Most machines are delivered with lighter duty 10mm diameter linear rods and bearings.  These rods are subject to flex when working more dense materials.  To correct this problem, we offer our premium 12mm diameter, chrome plated, hardened linear rods – center tapped for M5 hardware (just like the OEM units – bolts in place for a quick upgrade).  We round out this must have upgrade, with four new precision low-profile 12mm linear bearings. Mount these new bearings within your OEM style Y-Axis linear slide blocks, or add our optional 82mm Tandem Linear Pillow Block Slides to this order and we will pre-install your bearings within the new tandem slides!

Note: This upgrade is certified for use on the NCPRO line of 3018-PRO machines and similar 3018 clones.  To ensure compatibility, measure your existing Y-Axis linear rails and extrusions, if they match up with the sizing below, then this upgrade is likely compatible with your 3018-PRO machine.

****Extending Y-Axis Travel and our 82mm Tandem Pillow Block requires inverting of the aluminum spoil board.****

Y-Axis Linear Rail = 290mm | Y-Axis Extrusion = 290mm

    I have your X-Axis rails and they are perfect. Shipping on this follow-up order was quick and like the X-Axis rails, the product looks and feels solid. Looking forward to installing these this weekend.
