The AirTAC Airtac SC40 Standard Cylinder SC40X100 is a genuine double-acting standard air cylinder with a Ø40mm bore and 100mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X100 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. With a 40 mm bore and 100 mm stroke, this model is well-suited for medium-duty clamping, pressing, and ejecting tasks where a compact footprint is required.
This basic-configuration unit features a 16 mm diameter piston rod with an M12x1.25 thread, PT1/4 ports, and a standard TPU seal for operation in temperatures from -20 to +70 °C. The body length A is 142 mm, giving a total extended length of approximately 242 mm. An adjustable pneumatic cushion at each end decelerates the piston to reduce end-of-stroke impact.

Provides a reliable 628 N push at 0.5 MPa to halt or divert light packages on conveyor lines, with adjustable cushioning for smooth, low-impact stopping.
Delivers up to 1130 N of force for pressing bearings, bushings, or pins into housings in semi-automated assembly fixtures.
Ideal for pneumatic clamping in woodworking or light metal fabrication jigs, where the 100 mm stroke provides ample clearance for part loading and unloading.
For applications requiring slightly more force, stepping up to the 50 mm bore SC50 series provides 982 N of push force at 0.5 MPa, while the 32 mm bore SC32 offers a more compact alternative at 402 N. The 100 mm stroke is well within the standard range for this bore, ensuring fast availability.
When replacing an existing cylinder, ensure a correct match across five key points: bore (40 mm), stroke (100 mm), port thread (PT1/4), mounting accessory (this is a basic model without brackets), and magnet option (no built-in magnet). This cylinder is a direct replacement for another AirTAC SC40X100 of the same configuration.
Quick checklist
The theoretical push force at 0.5 MPa is 628 N, and the pull force on the retract stroke is 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. Actual dynamic force is typically 70-85% of these values due to friction and system losses.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than a comparable ISO 15552 profile cylinder. It is dimensionally interchangeable only with another AirTAC SC40 tie-rod cylinder of the same stroke, port type, and mounting configuration.
