I have a linear slider with the following specs:

Max allowable dynamic moment: 36.3 Nm
Load capacity based on acceleration of: 0.3G
Offset distance from center of slider to center of load: 305mm

I did the following calcuation

36.2N*m = X(Kg) * 305mm * 0.3G * 9.8/1000
X = 40Kg or approx 88lbs

I can conclude this slide is capable of moving this mass.

Is my math correct?

The only thing that does not appear to make sense with the data you have supplied - is the mass of load (50lb = 22.7Kg). I am going to take a wild guess that there is a bit more to it than you have given us in your posting, like the orientation of the slider (vertical or horizontal) or something. I guess the thing that needs bottoming out, is why the lower load restriction of 50lb.

I would give the supplier a ring/email, and bottom it out with them, so that there are no misunderstandings, and consequent failures of the design/product you are working on.

Hope this helps.
