Double Acting Hollow Hydraulic Cylinder
RRH Double Acting Hollow Hydraulic Cylinder
The double-acting hollow hydraulic cylinder combines all the design features of single-acting and the superiority of double-acting design, thereby improving the operation and use speed, especially in the relatively long-stroke operation, it can make full use of the hydraulic traction.
The cylinder has a through-hole in the piston center, which is widely used in nuclear power plants, tunnel engineering, underground engineering, construction, and other occasions to achieve the pre-tightening process, and can also be used in other similar conditions.
