CPC MR 9ML, 350 mm

Product information "CPC MR 9ML, 350 mm"

Genuine CPC miniature linear guideway; single rail cut to length with a single long block. Highest preload (V1) and normal (N) precision guarantees a stiff / play-free and binding-free motion. The blocks feature an injection hole for lubrication and a seal from all sides (even the bottom).


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 lubricants (in no particular order):

Note: lubricants containing MoS2 or graphite must not be used.

GCr15 / Bearing Steel

GCr15 is a very well known and worlwide used bearing steel. For the looks and to improve resistance to rust, we oxidise them black!

440C SUS / Stainless Steel

440C is most famous as one of the best and most versatile cutlery steel. Its very hard, resistant to rust, is good for polishing and in general an overachiever in its area.


Our rails come preserved with oil so they are protected against the elements while waiting for being installed in a new printer. This oil needs to be removed before usage, it's not feasible as lubricant!


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.


Preload determines the stiffness of your linear guide. The higher the preload, the stiffer. Free running rails can wobble which will result in noise and vibrations and visible defects in your overall print quality (i.e. layer stacking). Our rails are specced with the highest preload level available - reducing noise and vibrations and improving your print quality!
