The AirTAC AirTAC SDA32X50BH 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 SDA32X50BH is a double-acting, single-rod compact cylinder engineered for tight axial spaces. Its riveted assembly significantly reduces mounting depth compared to conventional round-body units, delivering a push force of 402.1 N at 0.5 MPa. This specific configuration includes a male M10x1.25 piston rod end for secure mechanical load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
The 32 mm bore features a hard-anodized inner wall and operates on a PT1/8 port at speeds between 30 and 500 mm/s. End-stop deceleration is handled strictly by fixed NBR bumpers rather than adjustable air cushions. Because this SKU lacks the -S magnet option, it cannot support magnetic position sensing without modifying the order code.

Secures aluminum workpieces in a CNC machining center, utilizing the 402.1 N extend force and FKM seals to withstand exposure to synthetic cutting fluids.
Drives a short 50 mm stroke to seal medical blister packs, where the compact riveted body minimizes the machine's axial footprint and the fixed bumpers absorb the end stop.
Actuates a routing flap on a logistics conveyor, with the male M10x1.25 rod end providing a rigid threaded connection to the diverter arm mechanism.
When sizing this actuator, stepping down to an SDA25 provides 245.4 N of push force at 0.5 MPa, while stepping up to an SDA40 yields 628.3 N. For this 32 mm bore, 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. To order correctly, confirm the 50 mm stroke, PT1/8 port, male M10x1.25 rod thread, FKM seal option, and the absence of a piston magnet.
Note that a standard compact cylinder will drift and cannot hold a load if air pressure drops or the directional valve is centered. The fixed rubber bumper only decelerates the piston near the stroke end and does not function as a locking brake; applications requiring static holding need an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa and a speed range of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You must select the -S option code to add a magnet. Additionally, end stopping relies on fixed NBR bumpers, not an adjustable air cushion, so external shock absorbers are recommended for high-energy cycles.
