What are the classifications of hydraulic cylinders?

Hydraulic cylinders, as the core actuating components in hydraulic systems, are mainly responsible for efficiently converting hydraulic energy into mechanical energy, achieving linear reciprocating motion or swinging motion. Its structure is streamlined, performance is stable, and it can achieve smooth motion without the need for a deceleration device, and there is no transmission clearance, so it is widely used in various types of machinery. Based on different functions, hydraulic cylinders are usually classified into the following categories.

Main classification of hydraulic cylinders

Single-Acting Cylinders

A single acting hydraulic cylinder is a hydraulic device that can only generate one-way thrust through unilateral hydraulic oil pushing, and its reset needs to be completed by springs, self weight, or external loads. The device consists of a cylinder barrel, cylinder head, piston, piston rod, and sealing device. Hydraulic oil only acts on one side of the effective area of the piston, while the other end chamber is in contact with air.

Double-Acting Cylinders

Double acting hydraulic cylinder refers to a hydraulic cylinder that can input pressure oil from both sides of the piston. It is often used as a driving component for jacks. The actuator of a double acting hydraulic cylinder is the main output device of a hydraulic motion system. Although it varies in size, type, and design structure, this part is usually the most observable. These actuators convert liquid pressure into fast, controllable linear motion or force to drive the load.

Telescopic Cylinders

A telescopic hydraulic cylinder, also known as a multi-stage hydraulic cylinder, consists of two or more pistons. Its extension sequence is from large to small, and when retracted, it is from small to large. This hydraulic cylinder can achieve a longer stroke and a shorter length when retracted, with a compact structure.
