The AirTAC Airtac SC32 Standard Cylinder SC32X74 is a genuine double-acting standard air cylinder with a Ø32mm bore and 74mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X74 is a compact double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa (563 N at 0.7 MPa). With a 32 mm bore and 74 mm stroke, it suits short-to-medium linear moves where space is tight. The 12 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration at end-of-stroke.
This basic configuration ships with a TPU seal (NBR option available) and PT1/8 threaded ports. The body length A is 140 mm, giving a total extended length of approximately 214 mm. It is a genuine AirTAC SC cylinder, factory-tested to 1.5 MPa proof pressure and rated for continuous operation from -20 to +70 °C.

Ejects small plastic or metal parts from injection molds or stamping dies. The 402 N push force at 0.5 MPa is well-matched to compact tooling where a 74 mm stroke clears the part.
Actuates a small diverter flap on a conveyor line. The adjustable cushion prevents hard stops that could shake lightweight products off the belt.
Drives a short vertical Z-axis on a benchtop pick-and-place module. The 32 mm bore keeps the actuator footprint small while the 74 mm stroke handles vial or tube transfers.
The SC32 bore is the smallest in the SC family, ideal for light clamping, sorting, and feeding tasks. If you need more force, step up to the SC40 (628 N push at 0.5 MPa). For strokes above 300 mm on this 12 mm rod, consider an external guide or a guided cylinder to protect the rod bearing from side loads.
When replacing an existing cylinder, match five points: bore (32 mm), stroke (74 mm), port thread (PT1/8), mounting accessories (basic, no bracket), and magnet option (none). The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the cylinder pushes with 402 N and pulls with 345 N. At 0.7 MPa, push force rises to 563 N. The maximum operating pressure is 1.0 MPa (724 N push). The theoretical force at 1.0 MPa is 82 kgf.
No. The SC series is a tie-rod cylinder and is shorter than an ISO 15552 cylinder. The mounting dimensions, body length (A=140 mm), and accessory interfaces are different. Only replace another AirTAC SC32 cylinder or a tie-rod cylinder with matching bore, stroke, port, and mounting dimensions.
