The AirTAC Airtac SC32 Standard Cylinder SC32X45 is a genuine double-acting standard air cylinder with a Ø32mm bore and 45mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X45 is a compact double-acting pneumatic cylinder from the AirTAC SC tie-rod series, pairing a 32 mm bore with a 45 mm stroke. At 0.5 MPa it generates 402 N of push force and 345 N of pull force, making it a capable actuator for light clamping, sorting, and ejector tasks where space is limited.
Its 12 mm diameter piston rod and M10x1.25 rod thread provide good rigidity for short-stroke applications. The body length A is 140 mm, giving a total extended length of approximately 185 mm. Adjustable pneumatic cushioning (21 mm cushion length) decelerates the piston at both ends, reducing end-of-stroke impact and noise.

The 402 N push force at 0.5 MPa is ideal for light-duty clamping fixtures in CNC machining and assembly jigs, holding small components securely during drilling or bonding.
With a 45 mm stroke and compact 140 mm body, this cylinder fits tight conveyor lanes to actuate diverter gates, sorting small packages or electronic components by weight or barcode.
The fast 30-800 mm/s speed range and adjustable cushioning suit repetitive pressing tasks like hot-stamp marking, label application, or date coding on flat surfaces.
Choose the SC32X45 when you need a compact actuator with around 400 N of push force. If your load demands more force, the SC40 series offers 628 N push at 0.5 MPa with a 16 mm rod. For lighter, faster applications, stepping down to a smaller bore may be possible, but the SC32 is the smallest bore in the SC family.
To replace an existing cylinder, match five points: 32 mm bore, 45 mm stroke, PT1/8 port thread, the required mounting accessory (this basic model has no bracket), and whether a magnet is needed (this model has no built-in magnet). The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard operating pressure of 0.5 MPa, the SC32X45 delivers 402 N of push force and 345 N of pull force. At the maximum operating pressure of 0.9 MPa, push force reaches 724 N. The theoretical maximum force at 1.0 MPa is 82 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder (body length A=140 mm for the SC32). The mounting dimensions and end-cap profiles differ, so it is not a drop-in replacement for ISO 15552 profile cylinders. It directly replaces another AirTAC SC32 cylinder with the same stroke, port thread, and mounting configuration.
