How many types of pneumatic cylinders and accessories?

Introduce

Modern industries such as automotive manufacturing, electronics assembly, food packaging, and machining heavily rely on pneumatic cylinders to achieve automation, enhance production efficiency, and improve product quality.

A pneumatic cylinder is an actuator that converts the energy of compressed air into mechanical motion — either linear or rotary. It is a core component in industrial automation systems.

Key Features

Powerful Drive Force: Provides reliable actuation for material handling, positioning, clamping, pushing, and more.

Simple Structure & Easy Maintenance: Compared with electric or hydraulic actuators, pneumatic cylinders are compact, easy to maintain, and quick to replace.

Fast Response & Precise Control: Ideal for high-speed, repetitive automation tasks.

Low Cost & Environmentally Friendly: Uses clean compressed air, with relatively low equipment and operating costs, and high safe

Adaptability to Harsh Environments: Operates reliably in high-temperature, humid, or dusty environments.
