The AirTAC AirTAC SDA32X20SH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 20mm 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 SDA32X20SH is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly merges the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth compared to conventional round-body units. Delivering 402.1 N of push force at 0.5 MPa, it is tailored for short 20 mm strokes where space is at a premium.
This configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. The -H option specifies fluororubber (FKM) seals for enhanced thermal and oil resistance. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow high-speed approaches or utilize external shock absorbers for heavy kinetic loads.

Drives a high-speed routing spindle on an electronics assembly line, utilizing the 20 mm stroke and FKM seals to resist flux contamination while handling the 241 N safe working load.
Applies precise clamping pressure on a thermoforming line, where the compact 32 mm body saves axial depth and the integrated magnet triggers reed or electronic switches to confirm seal closure.
Pushes stamped aluminum parts out of a progressive die, relying on the fixed NBR bumper to decelerate the 12 mm piston rod at the end of its 20 mm extension.
When sizing this 32 mm bore actuator, stepping down to the SDA25 yields 245.4 N of push at 0.5 MPa, while stepping up to the SDA40 provides 628.3 N. For this specific SDA32X20SH model, a safe working load is approximately 241 N (60% of the 0.5 MPa rating), translating to a vertical lift capacity of roughly 20.5 kg with a 2:1 safety margin. Confirm your ordering essentials: 32 mm bore, 20 mm stroke, PT1/8 port, female M6x1.0 rod thread, plus the S magnet and H FKM seal options. Note that a standard cylinder drifts if air pressure drops; utilize an external rod lock or pilot-operated check valve if the application demands fail-safe load holding.
Quick checklist
This 32 mm bore double-acting cylinder generates 402.1 N push and 345.6 N pull at 0.5 MPa, increasing to 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 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds from 30 to 500 mm/s.
No, the piston will drift if air pressure drops or the valve is centered. The fixed NBR bumper only decelerates the rod near the stroke end and does not function as a locking brake. To maintain a vertical load safely, you must install an external rod lock or a pilot-operated check valve.
