Abstract

A fluid operated linear motor of the piston and cylinder type. The piston is secured to a rod by a threaded connection and the mating threads are proportioned and dimensioned so that pivotal movement available in the threaded connection is enough to compensate at least in part for manufacturing tolerances and eccentricities and prevent or reduce abnormal distribution of lateral forces by the piston on the outer cylinder.
