The AirTAC AirTAC SDA50X75S Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 75mm 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 SDA50X75S 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 shortened axial footprint, conserving valuable machine depth where standard round bodies cannot fit. The 50 mm bore features a hard-anodized inner wall and a 20 mm piston rod.
This specific configuration includes the -S option, meaning it carries a built-in piston magnet designed to interface with AirTAC reed or electronic switches housed in the peripheral body grooves. The end caps absorb impact via a fixed NBR bumper rather than an adjustable air cushion, so high-energy cycles require slowing the approach or adding external shock absorbers. It operates efficiently between 0.15 and 1.0 MPa, drawing air through PT1/4 ports.

Drives the folding mechanism on continuous packaging lines, utilizing the 981.7 N extend force to swiftly close heavy corrugated cardboard flaps before sealing.
Pushes loaded pallets onto secondary transfer lanes within distribution hubs, where the 75 mm stroke and 50 kg vertical lift margin provide robust lateral redirection.
Secures heavy cast iron housings inside machining centers, saving Z-axis mounting depth while maintaining a 589 N safe working grip against cutting vibrations.
When sizing this actuator, evaluate your neighbors: stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa, while the larger SDA63 provides 1558.6 N. The 981.7 N output at 0.5 MPa translates to a safe working load of roughly 589 N (about 60% capacity) and a vertical lift capability near 50 kg with a 2:1 safety margin. To order correctly, confirm the 50 mm bore, 75 mm stroke, PT1/4 port thread, female M10x1.5 rod end, and the required -S magnetic piston.
Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centered. The fixed NBR bumper only decelerates the piston near the stroke limits and does not function as a locking brake. If your application must hold a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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. The theoretical maximum push force is 200 kgf at 1.0 MPa, which is the maximum operating pressure.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. The -S designation indicates a built-in magnet for tracking position with AirTAC reed or electronic switches along the body grooves.
