![]() ![]() Overall I am very happy with the product. Shafts for Support Rails Replace worn shafts in two-piece support-rail shaft systems, or mate with a support rail to create your own. 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. These shafts include a support rail for a stable setup that eliminates bending and prevents linear bearings from rotating. I like how the carriage blocks are shipped separately from the rail, minimizes damage. Makes me wonder if I should have even bothered, but I did anyways. The shipped rails before repacking are very smooth. 5 Great rails, very smooth even before repacking with oil.I ordered custom cut lengths and had them at my door within the week. Highly recommend.ĭecent linear rail and bearings. I have a Voron printer build in my future and I' m happy to have found my linear motion supplier. Packaging was good enough to account for handling neglect during transit, bubble wrap, in a tube in a box. Rail was true and dimensionally accurate. No debris found during inspection and only light oil cleaned up very easily. The bearing race using a strong light and magnification could have been ground and looked very good. Bearings measured 2.37mm with my calipers (for those that don' t know 3/32 = 2.38125mm) the precision 3/32 bearings I have in stock measure the same. Expected I would need to replace the bearings as is the case with most, boy was I surprised and impressed. 5 MGN 12 H-Type 400mm Rail and Carriage.It's most common to use two rail and two carriage blocks per rail for one axis. For light duty applications(such as laser engraver or 3D printer), it's acceptable to use one rail per one axis. The listing is for one rail plus one or two carriage blocks. MGN12H long carriage block size 27x45mm, M3 mounting hole spacing 20x20mm MGN12 rail ⌀3.5mm mounting hole spacing is 25mm Maximum travel distance error: +/- 17 microns per 300mm and +/- mm. ![]() Dimensional tolerance of height H and width N: +/- 40microns.Interchangeable bearing blocks/slider carriage for versatile configuration.Precision grade C grounded and polished.Genuine ZYLtech MGN12 linear and MGN12H long carriage block are both real grade C with the following details: There will be no “cut off” pieces from custom lengths. For example if you need two 250mm rails then each of them will require a custom length purchase.ġ.Select the custom length of your choiceģ.Specify your custom length in the Customer Note section.Ĥ.Select the quantity needed using the up or down arrows.ĭue to saw limitations and the hole spacing on a MGN rail, ZYLtech will determine which length rail to use for the custom length specified. If you need multiple rails in a custom length then you must order two custom lengths. If you order a 250mm custom length rail then you will receive one 250mm rail with smooth ends. ![]()
