The AirTAC AirTAC SDA50X55H Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 55mm 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 SDA50X55H is a double-acting, single-rod compact cylinder engineered with a 50 mm bore and 55 mm stroke. It generates 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. This specific SKU utilizes a fluororubber (FKM) seal variant, providing enhanced resistance to higher temperatures and oily environments compared to the standard NBR configuration.
Designed with a short riveted body, it drastically reduces axial mounting depth where a traditional round-body unit would not fit. The hard-anodized bore houses a two-way piston seal, while end-stops rely on a fixed NBR bumper to decelerate the piston rather than an adjustable air cushion. Because this base model lacks the -S magnet suffix, it cannot directly host AirTAC reed or electronic switches.

Secures the leading edge of stretch film against a pallet load using 981.7 N of extend force, with FKM seals surviving warm packaging facilities.
Actuates a routing flap to sort glass containers along a high-speed conveyor, benefiting from the 55 mm stroke and space-saving riveted body.
Pushes finished plastic parts out of a hot mold cavity, where the fluororubber seals prevent degradation near elevated tooling surfaces.
When sizing this unit, evaluate your force margins carefully. Stepping down to the SDA40 reduces the 0.5 MPa push capacity to 628.3 N, whereas stepping up to the SDA63 increases it to 1558.6 N. For the SDA50X55H, the safe working load is approximately 589 N (about 60% of the 981.7 N figure), translating to a vertical lift capability of roughly 50 kg with a 2:1 safety margin. Ensure your ordering essentials include the 50 mm bore, 55 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the FKM seal option.
Keep in mind 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 NBR bumper only decelerates the load near the stroke end rather than locking it. If your application demands strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder provides 981.7 N of push force and 824.7 N of pull force. At 0.7 MPa, push increases to 1374.4 N and pull to 1154.5 N. The theoretical maximum push is 200 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific SKU lacks the internal piston magnet, so it cannot host AirTAC reed or electronic switches. You would need the -S option code for sensing capabilities. Additionally, end-of-stroke deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.
