The AirTAC Airtac SC32 Standard Cylinder SC32X420 is a genuine double-acting standard air cylinder with a Ø32mm bore and 420mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X420 is a compact double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 402 N of push force at 0.5 MPa. Its 12 mm diameter piston rod and 21 mm adjustable air cushion make it well-suited for moderate-speed positioning tasks where space is limited.
With a 420 mm stroke, this model remains within the standard range for the 32 mm bore, offering a total body length of 560 mm. The PT1/8 port and M10x1.25 rod thread provide straightforward integration into existing pneumatic circuits, backed by genuine AirTAC build quality.

Actuates diverter gates on compact conveyor lines, providing the 402 N force needed to redirect lightweight packages reliably.
Secures small components in jigs during drilling or bonding, where the 12 mm rod offers sufficient rigidity for precise, repeatable clamping.
Drives a syringe pump or sampling mechanism in analytical equipment, benefiting from the clean, filtered-air operation and adjustable end-of-stroke cushioning.
For applications needing more force, stepping up to the 40 mm bore provides 628 N at the same 0.5 MPa pressure. At a 420 mm stroke, ensure the rod is not subjected to significant side loads; an external guide or a guided cylinder is recommended if the load is not perfectly axial to prevent rod bending. To guarantee a correct replacement, match the 32 mm bore, 420 mm stroke, PT port thread, basic mount, and confirm the absence of a magnet sensor option.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 402 N. At the maximum operating pressure of 0.9 MPa, the theoretical push force reaches 724 N.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is dimensionally interchangeable only with another AirTAC SC tie-rod cylinder of the same bore, stroke, and port configuration.
