Guys pls help what is a basic dynamic load rating: 32.75 C(kN) and basic static load rating: 76 Co(kN). I don't have a clue to what and how much it weight it can hold. I only know dynamic means while moving and static is while stand still. This I got from Hiwin linear guideway.

The C and Co are directions of load force, which you'd see in their illustration. C is usually straight down if the rail is down on a table and the block on top.
kN: kilo=1000 N=newton force=.224 lb

Thank you Mike!
so the calculation will be like this: (1000x.224)32.75=7336 lbs and as for the static is (1000x0.224)76= 17024 lbs?
about Co is for static load rating right? or it's C for static load rating? because in the manual it says basic static load rating : 76 Co(kN).
So if My calculation is correct I can put a max of 17024 lbs of material on top of one of the block?

Look in any linear bearing catalog or site. There is some simple algebra that you should go through to determine the equivalent loading that your setup puts on the bearings. Generally, as you can see, the bearings take far far more than we'd usually apply.
