The AirTAC AirTAC SDA50X100S 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 SDA50X100S 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 riveted assembly merges the barrel, rear cover, piston, and rod into a highly space-efficient unit, saving valuable axial mounting depth in tight machinery layouts. The 50 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable pneumatic operation.
This specific configuration includes a 100 mm stroke and a built-in piston magnet (the -S option) for position sensing via AirTAC reed or electronic switches mounted in the body grooves. End-stops rely on a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may need external shock absorption. Operating at speeds between 30 and 500 mm/s, it uses a PT1/4 port and a 20 mm rod to handle substantial loads.

Pushes cartons off a high-speed packaging conveyor using the 981.7 N extend force, where the 100 mm stroke clears the belt edge.
Raises a light pneumatic lift gate for 50 kg tote bins, utilizing the 100 mm travel to align bins with a lower tier.
Drives dowel pins into aluminum housings on an assembly line, relying on the 20 mm rod to resist deflection during the press fit.
Selecting this 50 mm bore model provides a safe working load of roughly 589 N (about 60% of the 981.7 N push force at 0.5 MPa), which translates to a vertical lift capacity of approximately 50 kg with a 2:1 safety margin. If your application requires less force, the SDA40 generates 628.3 N of push at 0.5 MPa; for heavier demands, the SDA63 steps up to 1558.6 N. Keep in mind that a standard SDA cylinder does not hold its position if air pressure drops or the valve is centered—the piston will drift, as the fixed bumper only decelerates the stroke end, so an external rod lock or pilot-operated check valve is necessary for fail-safe load holding.
When ordering, confirm the essentials: 50 mm bore, 100 mm stroke, PT1/4 port, the built-in magnet (-S), and the female M10x1.5 rod-end thread (or male M18x1.5 if specified). The 100 mm stroke sits well within the 130 mm maximum standard stroke for this bore, making it a readily available size.
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 and the pull force is 1154.5 N. The theoretical maximum push force is 200 kgf at the maximum operating pressure of 1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the piston. It is not an adjustable air cushion. For high kinetic energy loads, you should slow the approach speed or add an external shock absorber.
