ABSTRACT:
A pneumatic motor for providing bi-directional linear motion including a motor housing having a cylinder bore and a piston mounted on a piston rod positioned in the cylinder bore. The ends of the piston rod extend beyond the ends of the cylinder bore. The cylinder bore has a liner which acts to provide lubrication for movement of the piston in the cylinder bore and to provide a seal between the piston and the cylinder bore. The motor can be used to provide the drive means for a linear motion conveyor.
