An assembly system for a medium powered door opening and closing device especially for sliding doors. The assembly consists of a supporting profile located above the doorway with grooves or corresponding guides which act as travel tracks for rollers or wheels that function as door suspending members. The assembly also includes one or more channels through the profile to conduct pressure medium to a cylinder and/or a valve system and a cylinder to move the door, which cylinder is placed parallel to and in association with the profile. There is at least one connection hole between a profile flow channel and the cylinder for moving the piston and the piston rod. The cylinder is connected to supporting members and a valve system to control the cylinder.
