4.Lubricating your rails and ball screws
PLEASE NOTE: This process is NOT required for new machines; we have already
lubricated things perfectly for you in our factory before shipping.
To keep your linear motion system in great condition it is recommended to keep the
linear rails and ball screws rust free and lubricated. As a quick and easy solution, you
can apply a fine coating of lithium grease aerosol on the rails and ball screws and run
the machine back and forward a few times to spread the lubricant on the rails/ball
screws. This will coat the surface and keep them in good condition for years to come.
A more advanced and better method is to use a grease gun and use the grease nipples
provided on your linear bearings to lubricate them. For your rails a Kingchrome mini
grease gun works well. They can be special ordered from most hardware stores or
directly from Kingchrome. See this video on how to lubricate using a Kingchrome mini
grease gun: https://www.youtube.com/watch?v=ccsnIOzvoWI&t
If choosing to do the grease gun option, ensure that no more than 1 or 2 pumps is
used or you run the risk of blowing out the seals on the bearing blocks. This should be
performed no more than once per month with daily use of your machine. The
recommended lubricant is lithium grease or bar and chain oil.
The photos below show where the grease nipples are located and how you can
lubricate them.
