The AirTAC AirTAC SDA32X25BH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 25mm 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 SDA32X25BH is a double-acting single-rod compact cylinder engineered for tight axial footprints. Its riveted assembly keeps the overall length exceptionally short compared to round-body units, making it ideal for machinery where mounting depth is restricted. At 0.5 MPa it generates 402.1 N of push force and 345.6 N of pull force, operating at speeds between 30-500 mm/s.
This specific configuration includes a male M10x1.25 threaded piston rod for secure mechanical load coupling, paired with high-temperature fluororubber (FKM) seals. The 32 mm bore uses a PT1/8 port and relies on a fixed NBR bumper at each end to decelerate the stroke. Because this SKU lacks the -S magnet option, it cannot host magnetic reed or electronic switches.

Drives short linear indexing motions on automated tool changers, utilizing the compact riveted body to fit within tight spindle housings while providing 402.1 N of extension force.
Actuates sealing jaws on continuous flow wrappers where the FKM seals withstand higher ambient temperatures near heat tunnels, pushing products with 345.6 N retract force.
Pushes routing deflectors on conveyor lines to sort pallets, taking advantage of the male M10x1.25 rod end for rigid gate coupling and the short stroke to minimize protrusion.
Selecting this 32 mm bore provides a safe working load of roughly 241 N (about 60% of its 402.1 N output at 0.5 MPa), capable of a vertical lift around 20.5 kg with a 2:1 safety margin. If your application requires less force, the SDA25 offers 245.4 N at 0.5 MPa; stepping up to the SDA40 yields 628.3 N at 0.5 MPa for heavier demands. Remember that a plain compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near stroke end rather than locking the load, so an external rod lock or pilot-operated check valve is necessary for position holding. Confirm your ordering essentials: 32 mm bore, 25 mm stroke, PT1/8 port, male M10x1.25 rod thread, and FKM seals.
Quick checklist
This double-acting 32 mm bore cylinder provides 402.1 N push and 345.6 N pull at 0.5 MPa, and 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum push force is 82 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot host AirTAC reed or electronic switches. Detection would require external sensors. Additionally, it uses a fixed NBR bumper rather than an adjustable air cushion, so external shock absorbers are recommended for high-energy impacts.
