The AirTAC AirTAC SDA32X90H Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 90mm 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 SDA32X90H is a double-acting, single-rod compact cylinder engineered with a 32 mm bore and 90 mm stroke. It generates 402.1 N of push force and 345.6 N of pull force at 0.5 MPa, making it suitable for medium-duty positioning tasks. This specific SKU features an H-designation fluororubber (FKM) seal, providing enhanced resistance to higher temperatures and oil exposure compared to the standard NBR configuration.
The riveted body design significantly reduces axial mounting depth, saving valuable machine footprint space where a traditional round-body actuator would be too bulky. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy cycling. This model lacks a piston magnet, so it cannot directly mount AirTAC position switches without upgrading to the S option.

Routes cartons on a packaging conveyor using the 90 mm stroke to push items cleanly between lanes without excessive axial footprint.
Actuates safety barriers or access gates in machining centers, benefiting from the FKM seals when exposed to airborne cutting fluids.
Maintains thread tension mechanisms in textile machinery, utilizing the 402.1 N push force to keep fabric feeds aligned during high-speed weaving.
When sizing this 32 mm bore actuator, consider stepping down to the SDA25 if your load requires less force, as it provides 245.4 N of push at 0.5 MPa. Conversely, if your application demands more power, the SDA40 offers 628.3 N of push at the same pressure. For this 90 mm stroke configuration, the theoretical 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. To finalize your order, confirm the 32 mm bore, 90 mm stroke, PT1/8 port, female M6x1.0 rod thread, and the FKM seal option. Note that a standard compact cylinder will drift and lose its position if air pressure is lost or the valve is centered; the fixed bumper only slows the piston near the stroke end and does not function as a locking brake. If your application requires strict load holding, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 32 mm bore double-acting cylinder provides a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. At 0.7 MPa, the push force is 563 N and the pull force is 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa. It operates on filtered air between 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot support AirTAC reed or electronic switches. You would need the SDA32X90HS variant to utilize the built-in magnetic switch grooves. Additionally, this model uses a fixed NBR bumper for end-stop deceleration rather than an adjustable air cushion.
