The AirTAC AirTAC SDA40X65 Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 65mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA40X65 is a double-acting, single-rod compact cylinder engineered to deliver 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly shortened unit, drastically reducing axial mounting depth compared to traditional round-body actuators. This space efficiency makes it ideal for machinery where footprint constraints are critical.
This specific model features a 16 mm piston rod, a PT1/8 air port, and a 65 mm stroke within a hard-anodized bore. End-stop deceleration is handled by a fixed NBR bumper at each end rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorption. Because this SKU lacks the S option, it has no piston magnet and cannot support position sensing.

Provides the 628.3 N push force necessary to fold and secure heavy corrugated cardboard flaps on continuous packaging lines.
Actuates routing gates to redirect heavy pallets along merging conveyor sections where a short 65 mm stroke is sufficient.
Pushes formed metal components out of shallow press dies, utilizing the 16 mm rod to withstand repetitive lateral loads.
When sizing this actuator, consider stepping down to the SDA32, which provides 402.1 N of push at 0.5 MPa, or moving up to the SDA50, which yields 981.7 N at the same pressure. Based on the 628.3 N push rating, the safe working load is approximately 377 N (60% capacity), translating to a vertical lift capability of about 32 kg with a 2:1 safety margin. To confirm your ordering essentials for this model: specify the 40 mm bore, 65 mm stroke, PT1/8 port, female rod-end thread (M8x1.25), and no magnet. Note that a standard cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near the stroke end and does not function as a locking brake. For suspended loads, an external rod lock or pilot-operated check valve is required.
Quick checklist
At 0.5 MPa, the push force is 628.3 N and the pull force is 527.8 N. At 0.7 MPa, the push force is 879.6 N. The theoretical maximum push force is 128 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. Additionally, because this SKU lacks the S option, it has no piston magnet and cannot be used with reed or electronic switches.
