The AirTAC AirTAC SDA32X50H Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 50mm 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 SDA32X50H is a double-acting single-rod compact cylinder engineered with a 32 mm bore and 50 mm stroke. It generates 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. The -H designation indicates a fluororubber (FKM) seal variant, providing enhanced resistance to higher temperatures and oil exposure compared to standard NBR. Its short riveted body significantly reduces axial mounting depth, saving valuable machine footprint where a conventional round-body unit would not fit.
This model features a 12 mm piston rod and PT1/8 air ports. End-stop deceleration relies on a fixed NBR bumper at each end, which absorbs impact energy but is not a field-adjustable air cushion. Because this specific SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches. Operating speed spans 30-500 mm/s across a 0.15-1.0 MPa pressure range.

Secures aluminum workpieces inside CNC machining centers, where the FKM seal withstands elevated ambient heat and coolant mist while delivering 402.1 N of clamping thrust.
Actuates the pressure arm on a packaging line hot melt station, utilizing the 50 mm stroke to apply precise downward force without extending the machine frame depth.
Drives a short diverter gate on a 24V conveyor system, taking advantage of the compact riveted body to fit within tight transfer zone clearances.
When sizing this 32 mm bore unit, compare its 402.1 N push at 0.5 MPa against adjacent bores. Stepping down, the SDA25 provides 245.4 N; stepping up, the SDA40 yields 628.3 N. For this 50 mm stroke, the computed safe working load is roughly 241 N (about 60% of the 0.5 MPa push force), translating to a vertical lift capacity of approximately 20.5 kg with a 2:1 safety margin. To order, confirm the 32 mm bore, 50 mm stroke, PT1/8 port, female M6x1.0 rod thread, and the FKM seal option. Note that a plain compact cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near stroke end and does not function as a lock. To hold a load securely without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa, which is the maximum operating pressure.
No, this specific SKU does not include the -S piston magnet, so it cannot host AirTAC reed or electronic switches. You would need the -S variant for position sensing. Additionally, it uses a fixed NBR bumper for end-stop deceleration, not an adjustable air cushion.
