Regulate feed rates in the best way Hydraulic feed controls from ACE are recommended as the perfect solution e.g. when sawing, cutting, drilling and in order to prevent the stick-slip effect on pneumatic cylinders, amongst others. They can be precisely adjusted and provide speeds from 12 mm/min. with a very low feed force or up to 38 m/min. with a high feed rate. The maintenance-free, ready-to-install hydraulic feed controls are self-contained, hydraulic elements regulated by a precision throttle. The feed rate is set from the outside by turning the setting adjuster. The tried-and-testing rolling diaphragms used in many ACE shock absorbers also serve as a dynamic sealing element for a hermetic seal as well as volume compensation for the piston rod and resetting element.
