Linear Rail Selection Guide
Choosing the best linear guides for your build can be confusing. This table should give you a slight overview about our available options. We personal favorize the stainless steel version over the bearing steel version; opting for the black rails if you favor form over function only. A general recommendation for X axis are the CPC rails; they will reduce noise and improve overall print quality by reducing vibrations.

RobotDigg miniature linear guideway; single rail cut to length with a single long block. Highest preload (Z1) and normal (N) precision guarantees a stiff / play-free and binding-free motion.
Warranty
The blocks and rails are non-interchangeable - keep the blocks on the rails! A violation does expire warranty effectively.
Cleaning
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.
Lubrication
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):
CPC Lubrication Kit 18G
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.
