The AirTAC AirTAC SDA50X160B Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 160mm 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 SDA50X160B is a double-acting single-rod compact cylinder engineered to deliver 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. Its short riveted body assembly significantly reduces axial mounting depth compared to conventional round-body units, saving valuable machine footprint in tight assemblies. This specific SKU features a male M18x1.5 piston rod thread for robust mechanical coupling to your load.
Because the 160 mm stroke exceeds the 50 mm bore's 130 mm maximum standard stroke, this unit is provided as a non-standard, made-to-order configuration. The bore is hard-anodized and uses a fixed NBR bumper at each end to decelerate the piston near stroke limits. Note that this particular model lacks a piston magnet, meaning it cannot support position sensing without upgrading to the -S variant.

Drives a routing flap on a packaging conveyor to redirect heavy cartons, utilizing the 981.7 N extend force to overcome friction on the belt surface.
Raises a 50 kg workpiece tray vertically between machine processing stages, safely operating within the 589 N safe working load limit at 0.5 MPa.
Pushes corrugated cardboard blanks into a folding mechanism on an automated packing line, where the male M18x1.5 rod securely attaches the clevis fitting.
When sizing this actuator, consider stepping down to the SDA40, which provides 628.3 N of push at 0.5 MPa, or stepping up to the SDA63, which yields 1558.6 N at the same pressure. For this 50 mm bore, the safe working load is approximately 589 N (about 60% of the 981.7 N figure), allowing a vertical lift of roughly 50 kg with a 2:1 safety margin. Keep in mind a plain 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 it near the stroke end. For secure load holding, an external rod lock or pilot-operated check valve is required.
To order, confirm your essentials: 50 mm bore, 160 mm non-standard stroke, PT1/4 port, male M18x1.5 rod thread (B option), and no sensor magnet. Operating speed ranges from 30-500 mm/s.
Quick checklist
The SDA50X160B 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 operating pressure is 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. You would need the SDA50X160BS variant for sensing capabilities. Additionally, this model uses a fixed NBR bumper rather than an adjustable air cushion to decelerate the stroke end.
