Abstract
A fluid actuated piston and cylinder assembly with a cylinder housing having a head end and a cap end with a piston slidably reclined within the cylinder. A piston rod is attached to the piston for sliding movement with respect to the cylinder housing between an extended position and a retracted position with the piston rod extending out of the head end of the cylinder housing. A linear bearing assembly is interposed between the cylinder housing and piston rod for slidably engaging the piston rod along the axial direction with respect to the cylinder head. The linear bearing assembly frictionally engages the rod to prevent relative rotation motion between the piston rod and the cylinder.
