Ball screw linear unit / motorized

Essa are the Australian pioneers of a range of electric motor driven ball screw samplers that find particular application in collecting a representative samples from the material stream being discharged over the head pulley of a belt conveyor. These are setting new standards of performance and reliability that traditional chain, pneumatic and hydraulic drive samplers can find difficult to match.

The ball screw sampler maintains genuine uniform cutter speed through the falling stream; even when wear eventually occurs. The concept has been long term field proven in a broad range of medium to extra heavy applications.

The ball screw sampler is of simple yet rugged construction designed for maximum operational availability with low maintenance, in even the most arduous applications.

The electric motor driven ball screw mechanism produces a very rapid acceleration and deceleration time and results in a constant speed drive, which does not slow down when confronted with the falling stream be sampled. Its combination of a powerful directly coupled electric motor and the huge mechanical advantage produced by the ball screw and nut assembly ensures that sampler performance conforms most closely to recommended sample theory.
