What is SC series pneumatic cylinder?

Airtac SC series standard cylinders are tie-rod type standard pneumatic cylinders developed by Airtac. They are among the most commonly used and highly versatile cylinder types in industrial automation, and are widely applied in various machinery and automated production lines.

As a standard series within the Airtac cylinder range, the SC series adopts a tie-rod structure with standardized mounting dimensions and specifications. Powered by compressed air, it functions as a pneumatic actuator that converts air energy into linear reciprocating motion.
