MDF Panel Wall

[pitagoras]

Hi! I´m new to the forum so I hope I´m posting in the right place.

I plan to build a panel wall (a sliding hanging door) using those wheels and rails http://www.ducasseindustrial.com/images/productos/DN 80 SR/dn80sr_manual.pdf

The door measures 150x220 cm and I will use 25mm MDF. For this specs the door weight is about 50Kg.
8 screws will be supporting "hanging" the 50Kg of the door. Would that be enough or I should think some other solution?
Thanks!

What style door do you want?

For heavy doors a floor mounted system would be stronger since the weight will sit on the floor.

Thank you for your answers.
How much weight is "too much" for a hanging door?
It has to be a hanging door because the floor is not very regular (and will change at some point after the door is installed.
