MECHANICAL STROKE JAR

The LiMARĀ® Mechanical Stroke Jar, commonly known in the industry as the Spang Jar is a device designed to provide the fundamental bi-directional impact forces required to activate and manipulate mechanical tools downhole.

With two interlocking sliding sections, the impact is created when the upper sliding section reaches the end of the stroke & impacts with the interlocking lower section. The open and closed stroke positions can clearly be seen on the weight indicator by the winch operator at surface.
