CH/CHF hollow cylinders can due to the through-hole be used for both push or pull operations. For example, by inserting a rod through the cylinder, the compression force permit the cylinder to ne used for pulling operations.
CH/CHF cylinders have a capacity of 6 tons to 51 tons and is very compact in its exterior dimensions. That makes them suitable for integration into applications. CH62 has a gravity return & CHF62 cylinder has a spring return function.
