Abstract of the Disclosure A linear drive is disclosed as having a one piece main body with an elongate cylinder therein, and a piston moveable longitudinally within the cylinder. The main body has an elongate cylinder slot extending lengthwise thereof in communication with the cylinder along its entire length. A carriage is moveable along the cylinder on the exterior of the main body and a force transmitting member is coupled to the piston and extends radially outwardly of the cylinder through the slot for transmitting force from the piston to the carriage for effecting movement of the carriage. An elongate bearing cavity is provided within the main body. A bearing body is received within the bearing cavity and is coupled to the force transmitting member and to the carriage. The bearing body has a plurality of bearings for transmitting reaction forces to the main body with minimal friction while holding the piston against binding as it moves within the cylinder. For sealing the linear drive during movement, internal and external seals are provided.
