Hydraulic Cylinder Top Link Double-Acting w/ Locking Block 16 1/8-22 7/16'' 94820649Introduction: This double acting hydraulic cylinder converts the input hydraulic pressure energy into the mechanical energy of the piston's linear motion, thus providing strong pull and thrust fit for all types of mobile equipment. Its compact shape provides stable performance in compact devices. Through the welding and polishing process, the fixation is more durable, and it is also an ideal choice fit for applications in harsh environments.
