The AirTAC AirTAC SDA32X35SH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 35mm 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 SDA32X35SH 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 assembly merges the barrel, rear cover, and piston into an ultra-short profile, drastically reducing axial mounting depth compared to traditional round-body units. This space-saving footprint makes it highly effective for dense machinery layouts.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, plus fluororubber (-H) seals for enhanced thermal and oil resistance. The unit relies on a fixed NBR bumper at each end to decelerate the stroke, and the 12 mm rod uses an M6x1.0 female thread to couple with your payload.

Provides the 402.1 N extension force required to position PCB panels under a drill head, utilizing the 35 mm stroke and FKM seals to withstand ambient heat from nearby soldering processes.
Drives a mechanical arm to fold corrugated carton flaps prior to sealing, where the compact riveted body minimizes interference in tight conveyor side-frames and the magnet enables stroke confirmation.
Pushes machined aluminum parts out of a tooling tray using the 12 mm rod, relying on the fixed NBR bumper to absorb impact energy at the 35 mm stroke endpoint without requiring external cushions.
When sizing this 32 mm bore actuator, evaluate your neighbors: stepping down to the SDA25 yields 245.4 N of push at 0.5 MPa, while moving up to the SDA40 provides 628.3 N. For the SDA32X35SH, the computed safe working load is approximately 241 N (about 60% of the 402.1 N figure), translating to a vertical lift capacity of roughly 20.5 kg with a 2:1 safety margin. Confirm your ordering essentials: 32 mm bore, 35 mm stroke, PT1/8 port, female rod thread, -S magnet, and -H FKM seals.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift and the fixed bumper only decelerates near the end of travel. If your sequence demands strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides 402.1 N of push force and 345.6 N of pull force. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No, it uses a fixed NBR bumper at each end to decelerate the piston near stroke end, which is not a field-adjustable air cushion. Additionally, it does not function as a lock or brake; if air is lost, the piston will drift. To hold a vertical load safely, you must add an external rod lock or a pilot-operated check valve.
