The AirTAC AirTAC SDA16X50S Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 50mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA16X50S is a double-acting, single-rod compact cylinder engineered for tight machinery layouts. It generates 100.5 N of push force and 86.4 N of pull force at 0.5 MPa, utilizing a hard-anodized 16 mm bore and a two-way piston seal for reliable small-scale actuation.
Its riveted body design drastically reduces axial mounting depth compared to conventional round-body units, making it ideal for space-constrained assemblies. This specific configuration includes a built-in piston magnet (-S) for position sensing via AirTAC reed or electronic switches fitted into the body grooves. End-stopping relies on a fixed NBR bumper, which absorbs impact energy without the complexity of an adjustable air cushion.

Provides a compact 50 mm stroke to push singulated circuit boards out of a routing fixture, where the 100.5 N force is ample for lightweight ejection without stressing the panel.
Actuates a small diverter arm to route microtubes into collection racks, utilizing the built-in magnet to confirm home position via a solid-state switch in tight diagnostic equipment.
Tucks minor flaps on pharmaceutical cartons on a high-speed line, taking advantage of the short riveted body to fit within narrow conveyor side frames.
When sizing this 16 mm bore unit, consider stepping down to the SDA12, which yields 56.5 N of push at 0.5 MPa for lighter duties, or moving up to the SDA20, which provides 157.1 N if your application demands greater thrust. A practical safe working load for this model is approximately 60 N (about 60% of the 100.5 N figure), translating to a vertical lift capacity of roughly 5.1 kg with a 2:1 safety margin.
To finalize your order, confirm the 16 mm bore, 50 mm stroke, M5x0.8 port, and the required female M3x0.5 or male M5x0.8 rod-end thread. Note that this unit lacks a physical lock; if air pressure is lost or the valve is centered, the piston will drift, and the fixed bumper only decelerates the stroke end rather than holding the load. For suspended loads, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 16 mm bore cylinder delivers a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa. At 0.7 MPa, the push force is 140.7 N. The theoretical maximum push force is 21 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa and a speed range of 30-500 mm/s.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the piston, rather than an adjustable air cushion. For high-speed or high-energy cycles, you should slow the approach speed or add an external shock absorber to prevent premature wear.
