The AirTAC AirTAC SDA40X10H Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 10mm 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 SDA40X10H is a double-acting single-rod compact cylinder engineered for tight axial spaces. A riveted assembly joining the barrel, rear cover, piston, and 16mm rod drastically reduces mounting depth compared to round-body units. Delivering 628.3 N of push force at 0.5 MPa, it incorporates an FKM fluororubber seal to withstand elevated thermal and oily environments.
This specific configuration uses a 10mm stroke with a hard-anodized bore and a fixed NBR bumper at each end to decelerate the piston near stroke limits. Because this SKU lacks the -S option, it has no piston magnet and cannot support position sensing. Operating at speeds between 30-500 mm/s, it feeds through a PT1/8 port and offers a female M8x1.25 rod-end thread for straightforward load coupling.

Secures aluminum housings inside machining centers using the 628.3 N extend force, while the FKM seals resist coolant spray and elevated ambient heat.
Executes rapid 10mm tucks on packaging lines, where the shallow riveted body minimizes interference with moving conveyor belts and folding mechanics.
Punches short travel ejector pins in stamping presses, relying on the 16mm rod to push finished blanks clear of the die without side-loading.
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 moving up to the SDA50 provides 981.7 N. For this 40mm bore, the 628.3 N output at 0.5 MPa translates to a safe working load of roughly 377 N or a vertical lift capacity of about 32 kg with a 2:1 safety margin. To finalize your order, confirm the 10mm stroke, PT1/8 port, female M8x1.25 rod thread, and the FKM seal option. Note that a standard cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. If your application must hold a load without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 40mm bore double-acting cylinder generates 628.3 N push and 527.8 N pull at 0.5 MPa, or 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum push force is 128 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No. This model uses a fixed NBR bumper to decelerate at the stroke ends, which is not a field-adjustable air cushion. Additionally, because it lacks the -S magnet code, it cannot accept reed or electronic switches; you must select the -S variant for position sensing.
