 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 MGN15 linear and MGN15H 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


MGN15 rail ⌀3.5mm mounting hole spacing is 40mm

MGN15H long carriage block size 32x59mm, M3 mounting hole spacing 25x25mm


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.

    Great rails cut perfectly

    Posted by Sam on Jul 15th 2021

    I ordered my 460mm and 480mm rails and there were cut to that exact size. Rails feel a little slick so I cleaned the tiny bit of grease off with brake cleaner and relubricated. Runs real smooth on my printer.
