The AirTAC AirTAC SDA40X10B 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 SDA40X10B 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 body assembly significantly reduces axial mounting depth, making it highly effective for machinery where a standard round-body unit would simply be too long. The 16 mm piston rod features a male M14x1.5 thread, providing a robust mechanical coupling for your load.
This specific configuration includes fixed NBR bumpers at both stroke ends to absorb impact energy rather than relying on an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot host AirTAC reed or electronic switches. Operating efficiently between 30 and 500 mm/s, the hard-anodized 40 mm bore ensures durable performance across a 0.15-1.0 MPa pressure range.

Provides a rapid 10 mm stroke to eject cut circuit boards from a routing fixture, utilizing the 628.3 N push force to overcome vacuum grip without stressing the substrate.
Drives a short mechanical finger to tuck minor flaps on a packaging line, where the shallow 40 mm riveted body keeps the conveyor side-frame clear of obstructions.
Acts as a short-stroke positioning pin block in a metal forming press, using the male M14x1.5 rod thread to secure a hardened alignment tip for locating sheet metal blanks.
When sizing this unit, stepping down to the SDA32 yields 402.1 N of push force at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N at the same pressure. For this 40 mm bore, the safe working load is approximately 377 N (about 60% of the 628.3 N figure), translating to a vertical lift capacity of roughly 32 kg with a 2:1 safety margin. To finalize your order, confirm the 10 mm stroke, PT1/8 port, and the male M14x1.5 rod thread designated by the B option.
Keep in mind that a standard compact cylinder will not hold a load if air pressure drops or the directional valve is centered; the piston will drift, and the fixed bumper only decelerates the stroke near its end. If your application requires strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This double-acting cylinder generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 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. It operates within a pressure range of 0.15-1.0 MPa, handles temperatures from -20 to +70 C, and runs at speeds between 30 and 500 mm/s.
No, this model uses fixed NBR bumpers at the stroke ends for deceleration and does not feature an adjustable air cushion. Additionally, because this SKU lacks the -S magnet option, it cannot support AirTAC reed or electronic switches; you would need to specify the -S variant to enable sensor mounting in the body grooves.
