The AirTAC AirTAC SDA50X100H Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 100mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA50X100H is a double-acting single-rod compact cylinder engineered with a 50 mm bore and 100 mm stroke. It generates 981.7 N of push force and 824.7 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 seals. Its short riveted body significantly reduces axial mounting depth, saving valuable machine footprint where a conventional round-body actuator would be too long.
This model features a 20 mm piston rod and PT1/4 air ports. Instead of an adjustable air cushion, it relies on a fixed NBR bumper at each end to decelerate the stroke limits. Because this specific SKU lacks the S option, it has no piston magnet and cannot support magnetic sensing; adding the S variant enables the use of reed or electronic switches fitted into the body grooves.

Drives the mechanical arms that fold cardboard flaps on high-speed palletizing lines, utilizing the 100 mm stroke to clear the box path during retraction.
Actuates a routing gate on a beverage conveyor to sort bottles into labeling lanes, with the FKM seals surviving occasional washdown oil exposure.
Pushes raw bar stock into a CNC lathe chuck, where the 981.7 N extension force securely seats the part before clamping.
When sizing this actuator, consider stepping down to the SDA40, which yields 628.3 N of push force at 0.5 MPa, or moving up to the SDA63, which provides 1558.6 N at the same pressure. For the SDA50X100H, the computed safe working load is approximately 589 N (about 60% of the 981.7 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin. Ensure your ordering essentials specify the 50 mm bore, 100 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the FKM seal option.
Note that a standard compact cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end rather than acting as a lock. If your application requires a held load without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 981.7 N and the pull force is 824.7 N. At 0.7 MPa, the push force is 1374.4 N. The theoretical maximum push force is 200 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the operating speed ranges from 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. You would need to order the S option (SDA50X100HS) to enable sensing. Additionally, this model uses fixed NBR bumpers for end deceleration, which are not adjustable, so external shock absorbers may be needed for high-energy loads.
