Smooth Precision Motion
This MGN linear guide with carriage provides smooth, precise linear motion, ideal for 3D printer mechanics and other precision machinery. The design uses a light preload bearing to ensure accurate positioning and stability.
Size and Length Options
Available in multiple models (MGN7, MGN9, MGN12, MGN15) with selectable rail lengths to fit various project requirements.
- Guide widths: 7mm, 9mm, 12mm, 15mm
- Lengths available from 40mm to 550mm as per model
Installation and Maintenance Tips
If carriage movement feels tight initially, gently press and move the carriage multiple times to loosen it. Applying lubricant can improve smoothness and longevity.
- Light preload design may cause initial stiffness
- Lubricate rail or carriage for optimal movement

Product FAQ
Frequently asked questions
01 What does the package include?
The package includes 1 linear block (specified model) and 1 linear guide of your chosen length. Selecting only the block does not include rails.
02 Which sizes and lengths are available?
Models available are MGN7, MGN9, MGN12, and MGN15 with various lengths selectable by the customer.
03 What is the preload type of the MGN carriage?
The MGN carriage features a light preload, not a zero preload, which may make initial movement feel slightly stiff.
04 How to improve the movement if the carriage feels hard to move?
You can press the carriage and move it several times or apply lubricant to the rail or carriage to make it move more smoothly.
05 Are these products suitable for 3D printers?
Yes, these miniature linear rail slides and carriages are commonly used in 3D printers for accurate motion control.
06 Is there any high-concern chemical involved in these parts?
No, the product contains no high-concern chemicals.
07 Where is this product manufactured?
This product is manufactured in Mainland China.
08 What certifications does this product have?
The product holds CE certification.
09 Can I order large quantities or heavy goods?
Yes, but it is advised to contact customer service to discuss discounts and shipping costs for large or heavy orders.
10 Do the rails and blocks come preassembled?
No, the block and rail are separate; you need to choose the rail length when ordering, and blocks without rails do not include the rails.

Very poor quality - not smooth at all!
I bought this mgn9h linear guide, but the carriage gets stuck continuously and does not slide smoothly. There is too much friction and it locks up in multiple places. It is completely unusable for any precise project or 3d printer. Total junk, i am returning it.
It arrived well protected and exactly as I ordered.
Those are some of the shittiest linear rails i have ever received. i'v cleaned them in iso alcohol and then applied some high quality grease and there are a lot of bindings along the carriage path. also i've ordered two of them and received what i think are extremely different preloads. for my purposes in a 3d printer this is absolutely unusable.
