The Hydro-Check is a self-contained hydraulic resistance unit that is used to add hydraulic accuracy and smoothness to fast resilient action of pneumatic devices. It is a popular accessory to the Bellows Air Motor, Production machine components and other Schrader Bellows air cylinders.
The Hydro-Check puts precision control into pneumatic cylinders, linear actuators, work feed and drill feed systems without the cost and complexity of hydraulic pumps, valves and reservoirs.
Hydro-Checks may be used with Schrader Bellows cylinders in both integral and nonintegral configurations. Integral Hydro-Checks can be either inline or parallel mounted.
