- High-concerned chemical: None
- Brand Name: veekaft
- Model Number: MGN7 MGN
- Guide Width or Diameter: MGN
- Origin: Mainland China
- Certification: None
Packing Quantity:
1 set= 1 pc MGN12H/C(block)+1 pc guide
If you choose single 1 MGN12C or 1 MGN12H,
the actual quantity will be 1 block (do not include the guide).
* The guide rail and the slider are Class C, we think it is not necessary to provide additional steel balls, because the precision size of the steel ball may not match the size of the slider steel ball, such as -2μ -4μ ± 0 +2μ, which may shorten the slip The useful life of the block.
The slide block preload is ZF (normal clearance)/Z0 (no preload)/Z1 (light preload)
The pre-tightening force of ZF-Z0-Z1 increases successively,
Z0/ZA is shipped randomly and the price is the same.
When the slider is vertical,
ZF can slide under the gravity of the slider.
Z0 can slide under thrust.
This is only a rough description, not rigorous, without considering factors such as lubricating oil, it can only be used as a reference. (Considering that some buyers use this as a standard for the quality of the slider)
We recommend that most 3D printers or light desktop devices use ZF/Z0 preload
Z1 is only suitable for occasions where accuracy and life are required.
We also provide nickel-plated rails/chrome-plated rails/blackened rails/44C martensitic stainless steel rails, as well as stainless steel 440C sliders/plated sliders

I converted tevo little monster to linear rail. It is getting very silent after conversion. I will repeat for cnc machines.

Satisfied with the rails. No rust, no extra play on the bearing block, smooth movement. Good quality. Fast delivery via dpd.

They are not perfect, there are some minor scratches, movement is kind of smooth, one of them is slightly bumpy on one edge and i think the preload is different on each one. I’m going to use this for the z axis on a 3d printer, and probably buy more for the x and y.

Great finish quality, kart slides effortlessly, be sure to oil before installation.

They are overall pretty good there’s juste a bit of “friction” out of the bag but with cleaning an re-oiling it’s perfect.

Up to the job i need it for. Rolls smoothly with low friction and no off axis movement.
