The AirTAC AirTAC SDA50X65 Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 65mm 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 SDA50X65 is a double-acting single-rod compact cylinder delivering 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. Its riveted assembly joins the barrel, rear cover, piston, and rod into a highly shortened unit, saving substantial axial mounting depth compared to conventional round-body actuators. This space efficiency makes it ideal for machinery where footprint reduction is critical.
This specific configuration features a 50 mm bore, a 65 mm stroke, and a 20 mm piston rod. Air connects via PT1/4 ports, while the rod end offers a female M10x1.5 thread. The bore is hard-anodized for longevity, and end-stops rely on a fixed NBR bumper rather than an adjustable air cushion. This SKU is built without a piston magnet, so it cannot host magnetic switches; adding an -S option code enables reed or electronic switch sensing.

Pushes cartons weighing up to 50 kg onto secondary packaging lines with a 65 mm stroke, utilizing the short body to fit within tight conveyor side-frame clearances.
Provides 981.7 N of extend force to eject formed plastic parts from low-clearance mold tooling, where the fixed NBR bumper absorbs the repetitive end-stop impact.
Acts as a pneumatic stopper for 50 kg workpiece pallets in vertical lifting stations, requiring an external pilot-operated check valve to prevent drift when air is removed.
When sizing this actuator, consider stepping down to the SDA40, which provides 628.3 N of push at 0.5 MPa, or moving up to the SDA63, which yields 1558.6 N at the same pressure. At 981.7 N, this 50 mm bore achieves a safe working load of roughly 589 N (about 60% of the 0.5 MPa figure) and can vertically lift approximately 50 kg with a 2:1 safety margin. If your mechanism must maintain vertical position during air loss or valve centering, note that a standard SDA cylinder will drift; an external rod lock or pilot-operated check valve is required for secure load holding.
To order, confirm the essentials: 50 mm bore, 65 mm stroke, PT1/4 port thread, female M10x1.5 rod end, and no sensor magnet. The fixed NBR bumper decelerates the piston near stroke end but is not a field-adjustable cushion; for high-energy cycles, add an external shock absorber or slow the approach speed. Operating speed ranges from 30-500 mm/s.
Quick checklist
This double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, and 1374.4 N push at 0.7 MPa. The theoretical maximum push force is 200 kgf at 1.0 MPa. The maximum standard stroke available for this 50 mm bore is 130 mm.
No, this specific SKU lacks the internal piston magnet, so it cannot host reed or electronic switches. You must select the -S option code to enable sensing. Additionally, end-stopping is handled by a fixed NBR bumper, not an adjustable air cushion, so external shock absorbers are recommended for high-speed operations.
