SI Series Standard Cylinders Standard cylinder Double-acting cylinder Industrial automation cylinder Pneumatic linear actuator

SI series standard cylinders, with bore diameters ranging from 32 to 200 mm, double-acting, operating at 0.1–1.0 MPa, featuring adjustable cushioning and designed for industrial automation linear‑drive applications.

Product Details

Product Overview
The SI series standard pneumatic cylinders are double-acting linear drive components designed specifically for industrial automation applications. They cover bore sizes from 32 mm to 200 mm, support multiple mounting configurations, and feature an adjustable cushioning design. These cylinders operate with filtered compressed air and can run stably under working pressures of 0.1–1.0 MPa and ambient temperatures ranging from -5°C to 70°C. They are widely used in various automated equipment for linear push-pull, lifting, and positioning control tasks.

Operating Principle

  1. Compressed air enters the rodless chamber through the inlet pipe, pushing the piston and piston rod outward;
  2. When air is supplied in the reverse direction, it enters the rod-side chamber, retracting the piston and piston rod and thus achieving reciprocating linear motion;
  3. At the cylinder’s end, the adjustable cushioning mechanism allows users to regulate the exhaust flow via a throttle valve, slowing down the piston’s movement and reducing impact and noise at the stroke’s terminus;
  4. Multiple mounting options are available, enabling flexible selection based on equipment installation requirements and accommodating diverse mounting layouts.
