Product Introduction

　　This series of cylinders consists of 14 different cylinder diameters and 28 different specifications of single piston double acting differential cylinders composed of four speed ratios. In addition, there are three types of cylinder head flange type, middle ear shaft installation type, and base installation type, which can also be made into double piston rod double acting constant velocity oil cylinders. In addition, there is no end buffering and both ends have buffering, forming 384 varieties with the above 28 specifications. Especially suitable for harsh and heavy-duty working conditions, it is widely used in industrial sectors such as steel, casting, forging, and mechanical manufacturing. Working pressure of 25Mpa, 35Mpa, and ambient temperature of -30 ℃~100 ℃.
