HW-MGN12

 If you order a 250mm custom length rail then you will receive one 250mm rail with smooth ends.

If you need multiple rails in a custom length then you must order two custom lengths. For example if you need two 250mm rails then each of them will require a custom length purchase.

1.Select the custom length of your choice

 (<500mm or <1000mm). 

2.Then select the number of carriages. 

3.Specify your custom length in the Customer Note section.

4.Select the quantity needed using the up or down arrows. 

Due to saw limitations and the hole spacing on a MGN rail, ZYLtech will determine which length rail to use for the custom length specified. There will be no “cut off” pieces from custom lengths. 

 

Genuine ZYLtech MGN12 linear and MGN12H long carriage block are both real grade C with the following details:

 

  • Precision grade C grounded and polished
  • Interchangeable bearing blocks/slider carriage for versatile configuration
  • Dimensional tolerance of height H and width N: +/- 40microns
  • Maximum travel distance error: +/- 17 microns per 300mm and +/- 23 per 1000mm

 

MGN12 rail ⌀3.5mm mounting hole spacing is 25mm

MGN12H long carriage block size 27x45mm, M3 mounting hole spacing 20x20mm

 

The listing is for one rail plus one or two carriage blocks . For light duty applications(such as laser engraver or 3D printer) , it's acceptable to use one rail per one axis. It's most common to use two rail and two carriage blocks per rail for one axis.

    MGN 12 H-Type 400mm Rail and Carriage

    Posted by Ken O on Sep 6th 2021

    Passed every inspection I made. Expected I would need to replace the bearings as is the case with most, boy was I surprised and impressed. Bearings measured 2.37mm with my calipers (for those that don&#039;t know 3/32 = 2.38125mm) the precision 3/32 bearings I have in stock measure the same. The bearing race using a strong light and magnification could have been ground and looked very good. No debris found during inspection and only light oil cleaned up very easily. Rail was true and dimensionally accurate. Packaging was good enough to account for handling neglect during transit, bubble wrap, in a tube in a box. I have a Voron printer build in my future and I&#039;m happy to have found my linear motion supplier. Highly recommend.

    Decent linear rail and bearings. Plenty good for 3d printer. I ordered custom cut lengths and had them at my door within the week.

    Great rails, very smooth even before repacking with oil

    Posted by Brad on Mar 10th 2021

    The shipped rails before repacking are very smooth. Makes me wonder if I should have even bothered, but I did anyways. I like how the carriage blocks are shipped separately from the rail, minimizes damage.
    I did have one misstep on my part I ended up losing some ball bearings during repacking on one rail, so I ordered some new ceramic bearings and found they are even smoother and quieter than the steel ones. Overall I am very happy with the product.
