The AirTAC AirTAC SDA32X50SB Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 50mm 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 SDA32X50SB is a double-acting single-rod compact cylinder engineered to deliver 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. Its riveted body design merges the barrel, rear cover, piston, and rod into a highly shortened assembly, saving valuable axial mounting depth in tight machinery layouts. The hard-anodized bore ensures smooth operation across the 30-500 mm/s speed range.
This specific configuration includes a built-in piston magnet (S) for position detection via AirTAC reed or electronic switches mounted in the body grooves. It is also equipped with a male-thread piston rod end (B), featuring an M10x1.25 thread for secure mechanical load coupling. End-stops rely on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy cycles.

Actuates short-stroke tool release mechanisms on machining centers where axial space is restricted but 402.1 N of extension force is required to overcome spindle spring tension.
Drives the folding arms on automated packaging lines, utilizing the male M10x1.25 rod end for rigid linkage attachment and the built-in magnet to confirm flap position.
Pushes lightweight pallets off a main conveyor belt, relying on the fixed NBR bumper to absorb the kinetic energy at the end of the 50mm stroke without requiring bulky external cushions.
When sizing this 32mm bore actuator, consider stepping down to the SDA25 which provides 245.4 N of push at 0.5 MPa for lighter loads, or stepping up to the SDA40 which yields 628.3 N if your application requires greater thrust. For this 50mm stroke model, the computed safe working load is approximately 241 N (about 60% of the 402.1 N figure), allowing a vertical lift of roughly 20.5 kg with a 2:1 safety margin. Keep in mind that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and acts as neither a lock nor a brake. To hold a load securely without live pressure, you must integrate an external rod lock or a pilot-operated check valve. To order, confirm the 32mm bore, 50mm stroke, PT1/8 port, built-in magnet (S), and male M10x1.25 rod thread (B).
Quick checklist
This double-acting cylinder generates 402.1 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum push force is 82 kgf at 1.0 MPa, with a proof pressure rating of 1.5 MPa.
No, the piston will drift if air pressure is lost or the directional valve is centered. The fixed NBR bumper only decelerates the rod near the stroke end and does not function as a locking brake. For vertical load holding, an external rod lock or pilot-operated check valve is required.
