Miniature linear guideway; single rail (MGNR09R) cut to length with a single long block (MGN9H). As a special feature, the linear rail is blued black and the linear block has black plastic caps. Previous batches used to have black and red encaps, but due to customer demand for a neutral color that does not interfere with accent colors, wo opted for black endcaps.
The blocks and rails are non-interchangeable - keep the blocks on the rails! A violation does expire warranty effectively.
We strongly recommend to clean the rails before lubrication. Put a zip tie through the very last holes to ensure the block can not escape the rail. Fill a glass with some grease solvent and soak the blocks for at least an hour. Rinse the blocks and wipe the rail from any residue grease with a lint-free cloth.
We recommend to lubricate the ball races and bearing balls with grease, and cover the entire rail itself in a thin coat of grease to prevent oxidation. Recommended lubricatants (in no particular order):
- Fuchs Planto Multispray S
- Fuchs Lagermeister BF2
- Mobilux EP 1 or EP 2
- HIWIN G05
Note: lubricants containing MoS2 or graphite must not be used.

Great for the price
First of all, they are comparingly cheap, thats very important to be kept in mind.
But since other could end with double the price or more than these rails, for the given price the quality is fitting.
All in all they run smoothly if greased correctly, they dont have bumps or other irregularitys or damages.
the pretensioning could be a little better, also the tolerances of the carriages with the rails,
especially with an rotation moment, some rails can get a little rough running, but they dont get catchy, so its probably fine.
Also you can feel a variation between multible rails, so i would advice to sort them from strong to looser tensioned and fit them accordingly to needance of the places (looser rails e.g. for Z axis, the stronger ones for the Y or X axis)
All in all, after inststallation, they run great.
Their quality is enough for the given task.
So i would recommend the rails.
Shipped nice and secured.
very good quality
Nicely packed, very secure for transport. The black colour is very resilient and the quality of the rails is excellent with no play at all.
Good quality rail, well packed individually, really smooth after relubricating. Very cost effective
