MGN9 Linear Guide Rail
Friendly Reminder:
- Normally, there may be 1 or 2 missing balls on each side. The carriage block may get slightly stuck when it's full of balls because the balls on each side need some space to run properly.
- If the guide rail feels a bit stiff, please apply some lubricant, and it will run smoothly.
- The length mentioned on this page refers to the length of the rail, not the stroke of the slider.
- The guide rail may have a tolerance of 0.025mm or -0.025mm, but this does not affect its normal use.

These will not move even when the rail is 90 degrees straight up and down. I cleaned and lubricated them and nothing changed. They are tight and stick at the start. Would not recommend.

Easy to mount and very tolerant to sideways forces. We purchased to put on a FTC robot last year.

I got this to convert the X-Axis of my Ender 3 Pro to linear rails.The linear rail came with surprisingly good quality for a random linear rail from a company I haven't heard of. It doesn't stick, came with extra bearings, and works like a charm. As with any linear rail, I would recommend cleaning out the factory oil/grease and re-lubing it yourself.

Review of KGTCN Linear Rail Guide MGN9H 300mm Miniature Linear Sliding Guideway with 1PCS Linear:First off be sure to take note that these are MINIATURE rails (type MGN9H) and not the larger sized ones (type MGN12H) you normally find used on 3D printers. The mounting plate and the size of the rails is smaller.These rails came well packaged and included spare bearings and dummy rail. The operation is smooth with no binding. Rail is straight. No complaints.
