A technique facilitates application of increased force in various well applications while limiting the overall time period of the operation by automatically utilizing two modes of operation. In some well applications, the technique automatically applies increased force to facilitate shearing of a tubular product in a timely manner. By way of example, the system may be utilized to rapidly advance rams to the point of contact with the tubular product extending through well equipment, e.g. through a blowout preventer (BOP), and then to automatically shift to a slower advance but higher force mode. The higher force mode facilitates shearing of a variety of tubular products in a variety of well applications.

Devices, systems, and methods are provided for a through-rotary centralizer for downhole operations. The through-rotary centralizer assists with centralizing a tool operating downhole, such as a bit. The through-rotary centralizer has a mandrel, a sleeve rotatably mounted around the mandrel, a floating hub slidably mounted around the sleeve, and centralizing arms mounted to the sleeve and floating hub.
