The AirTAC AirTAC SDA40X65B 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 SDA40X65B is a double-acting, single-rod compact cylinder engineered for tight axial spaces. It generates 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. A hard-anodized bore and two-way piston seal ensure durable service within the 0.15-1.0 MPa operating range.
This specific SKU features a male M14x1.5 threaded piston rod end for secure mechanical load coupling. Because it lacks the -S option, there is no piston magnet, so magnetic position sensing is not supported. The riveted body design significantly reduces overall mounting depth compared to traditional round-body cylinders.

Secures aluminum engine blocks during machining operations, utilizing the 628.3 N extend force to hold components firmly against locator pins.
Drives mechanical arms to tuck corrugated box flaps prior to tape sealing, where the short 65mm stroke and compact body depth minimize frame interference.
Actuates a routing pop-up gate on a logistics sorting line, using the male M14x1.5 rod thread to attach the pusher blade directly.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA32 yields 402.1 N of push at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N. For this 40mm bore, a safe working load is approximately 377 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 32 kg with a 2:1 safety margin. To finalize your order, confirm the 65mm stroke, PT1/8 port, and the male M14x1.5 rod thread. Note that a standard cylinder drifts when air pressure is lost or the valve is centered; the fixed NBR bumper only decelerates the stroke end rather than locking the load. For position holding, an external rod lock or pilot-operated check valve is required.
Quick checklist
This double-acting cylinder delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, the push increases to 879.6 N. The theoretical maximum push is 128 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-500 mm/s.
No. This model uses fixed NBR bumpers at both ends to decelerate the piston, which cannot be field-adjusted for speed; add an external shock absorber for high-energy loads. Additionally, because this SKU lacks the -S magnet code, it cannot accept reed or electronic switches.
