The AirTAC AirTAC SDA32X45H Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 45mm 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 SDA32X45H is a double-acting, single-rod compact cylinder engineered with a 32 mm bore and 45 mm stroke. It generates 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. This specific SKU utilizes fluororubber (FKM) seals, providing enhanced resistance to higher temperatures and oily environments compared to standard NBR. The short riveted body significantly reduces axial mounting depth, making it highly effective for machinery where a conventional round-body or profile cylinder would simply not fit.
This model features a 12 mm piston rod and PT1/8 air ports. Instead of an adjustable air cushion, it relies on a fixed NBR bumper at each end to decelerate the piston near the stroke limits. Because this particular unit lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches. Operating efficiently between 30-500 mm/s, it is built for demanding spatial constraints.

Secures aluminum engine blocks during machining operations, utilizing the 402.1 N extend force to hold parts firmly against locators without demanding excessive axial bay depth.
Drives mechanical arms to tuck corrugated box flaps prior to tape sealing, where the 45 mm stroke and FKM seals withstand occasional lubricant mist in high-speed packaging lines.
Pushes molded plastic parts out of small injection molds, leveraging the 12 mm rod and compact riveted body to fit within tight stripper plate assemblies.
When sizing this actuator, evaluate your force margins carefully. Stepping down to an SDA25 yields 245.4 N of push at 0.5 MPa, while stepping up to an SDA40 provides 628.3 N. The SDA32X45H offers a safe working load of roughly 241 N (about 60% of its 402.1 N capacity) and can vertically lift approximately 20.5 kg with a 2:1 safety margin. Remember that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the end of travel. For suspended or gravity-loaded applications, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 32 mm bore, 45 mm stroke, PT1/8 port, FKM seal option, and the default female M6x1.0 rod-end thread.
Quick checklist
This 32 mm bore double-acting 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 supports a speed range of 30-500 mm/s.
No, this cylinder uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. For high kinetic energy loads, add an external shock absorber. Additionally, this SKU lacks a piston magnet, so it cannot support reed or electronic switches; you would need the -S option variant for position sensing.
