The AirTAC SDA50X70 Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 70mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA50X70 is a double-acting, single-rod compact cylinder engineered to deliver a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. Its riveted assembly integrates the barrel, rear cover, piston, and rod into a highly shortened axial footprint, making it ideal for machinery where a standard round-body unit would protrude too far. The hard-anodized bore minimizes friction, while the 20 mm piston rod provides a robust interface for load coupling.
This specific configuration lacks the internal piston magnet, meaning it cannot host AirTAC reed or electronic switches for position sensing. End-of-stroke deceleration is handled purely by fixed NBR bumpers rather than an adjustable air cushion, so high-energy cycles may require an external shock absorber to prevent impact damage.

Actuates a routing flap on a logistics sorting line, utilizing the 70 mm stroke to push parcels efficiently without consuming excessive frame width.
Drives the mechanical folder arms on a continuous packaging machine, delivering the 981.7 N push needed to square heavy corrugated cardboard before taping.
Ejects stamped metal parts from a shallow die bed, where the shortened body length prevents interference with the press ram and guide pillars.
If your application demands less force, stepping down to the SDA40 yields 628.3 N at 0.5 MPa, whereas stepping up to the SDA63 provides a substantial 1558.6 N. To finalize your order, confirm the 50 mm bore, 70 mm stroke, PT1/4 port, female M10x1.5 rod-end thread, and the absence of the magnet option.
Remember that this compact unit will not hold a load if air pressure drops or the directional valve centers; the piston will drift. For vertical or suspended loads requiring fail-safe holding, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This double-acting cylinder generates a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. At 0.7 MPa, the push increases to 1374.4 N. The theoretical maximum push is 200 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s.
No. This model uses fixed NBR bumpers at the stroke ends for deceleration, which cannot be field-adjusted like an air cushion. Additionally, this specific SKU lacks the internal magnet (-S option), so it cannot support AirTAC reed or electronic switches for position detection.
