I am trying to find a company that sells to the public Aluminum Profile to make Linear Actuators.

The only profile I can find is by Techno-Isel : http://www.techno-isel.com/LMC/Products/IselRail500.htm

The only problem with their setup is they force you to purchase their custom designed bearing rails with this profile so you get locked versus using THK or IKO linear bearing rails which is my preference.. Even though I do like their stuff!!!!

I'm guessing there has got to be a company somewhere that will sell this Aluminum Profile without the bearing rails attached..

Does anyone know??
