The AirTAC Airtac SC40 Standard Cylinder SC40X1320 is a genuine double-acting standard air cylinder with a Ø40mm bore and 1320mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1320 is a double-acting tie-rod cylinder with a 40 mm bore and an extended 1320 mm stroke, which exceeds the standard maximum of 1200 mm for this bore size, making it a made-to-order non-standard stroke unit. At 0.5 MPa it generates 628 N of push force and 528 N of pull force, driven by a 16 mm diameter piston rod with M12x1.25 male threads.
This cylinder features an adjustable pneumatic cushion at both ends with a 21 mm cushion length, allowing you to dial in smooth deceleration for high-speed loads. The body length A is 142 mm, giving a total extended length of approximately 1462 mm. PT1/4 ports and a standard TPU seal suit operating temperatures from -20 to +70 °C.

The 1320 mm stroke pushes or pulls parts across wide conveyor gaps or between distant stations, ideal for packaging lines where a compact 40 mm bore fits tight machinery envelopes.
Actuates diverters and sorting gates on production lines. The adjustable cushion protects the mechanism from impact at end-of-stroke, even under the 879 N force available at 0.7 MPa.
Controls pallet flow in gravity roller systems. The 16 mm rod and tie-rod construction provide reliable cycling in dusty warehouse environments when filtered air is maintained.
For applications needing 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 lighter 402 N. At a 1320 mm stroke, the 16 mm rod is susceptible to bending under side loads; always use an external guide or linear rail to prevent rod bearing damage and seal wear.
When replacing an existing cylinder, match five points exactly: 40 mm bore, 1320 mm stroke, PT1/4 port thread, basic mounting (no bracket), and no magnet. This SC model is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa the push force is 628 N and pull force is 528 N. At 0.7 MPa push reaches 879 N, and at the maximum operating pressure of 0.9 MPa it delivers 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 cylinder of the same stroke. It is not dimensionally interchangeable. Replace only with another AirTAC SC40 cylinder with the same 1320 mm stroke, PT1/4 ports, and basic mounting.
