CH/CHF hollow cylinders can be used for both push and pull operations due to the through-hole. For example, by inserting a rod through the cylinder, the push force can also be used for pulling operations, e.g. when extracting bushings from machine elements.
CH = Single acting steel hollow bore cylinders with gravity return
CHF = Single acting steel hollow bore cylinders with spring return
