The AirTAC Airtac SC40 Standard Cylinder SC40X105 is a genuine double-acting standard air cylinder with a Ø40mm bore and 105mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X105 is a 40 mm bore, 105 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It delivers 628 N of push force at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa, driven by a rigid 16 mm diameter piston rod.
With a compact body length A of 142 mm, the total extended length is approximately 247 mm. The adjustable air cushion (21 mm length) decelerates the piston smoothly at end-of-stroke, reducing impact noise. This model uses standard PT1/4 ports and TPU seals for a -20 to +70 °C operating range.

Actuates a gate or diverter arm on a light conveyor line, using the 105 mm stroke to push small packages into the correct lane.
Provides 628 N of holding force for jigs and assembly fixtures, securing workpieces during drilling, gluing, or ultrasonic welding.
Opens and closes a small ventilation or airflow damper in agricultural or HVAC equipment, operating reliably in dusty conditions with filtered air.
Choose the SC40X105 for light pressing, clamping, or sorting tasks where the 628 N force at 0.5 MPa is sufficient. If you need more force, the 50 mm bore SC50 series provides 982 N at the same pressure. For a smaller footprint, the 32 mm bore delivers 402 N.
To replace an existing cylinder, match five points: 40 mm bore, 105 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and the absence of a magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Replace only with another AirTAC SC tie-rod cylinder of the same bore, stroke, port, and mounting configuration.
