The AirTAC AirTAC SDA50X10S Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 10mm 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 SDA50X10S 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 unites the barrel, rear cover, piston, and rod into a highly abbreviated unit, drastically reducing axial mounting depth compared to conventional round-body designs. The 50 mm bore features a hard-anodized inner wall and a 20 mm piston rod.
Because this configuration includes the S option, a built-in piston magnet enables position detection using an AirTAC reed or electronic switch seated in the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. For high kinetic energy applications, slowing the approach speed or fitting external shock absorbers is advised.

Applies 981.7 N of lateral pressure to square printed circuit boards on an SMT line, utilizing the 10 mm stroke to conserve Z-axis machinery height.
Actuates a short mechanical arm to tuck packaging flaps on a high-speed cartoner, where the fixed NBR bumper safely absorbs the rapid end stop.
Drives a 20 mm rod to push small metal slugs from a progressive die set, requiring the S magnet to trigger a solid-state sensor for part confirmation.
When sizing this unit, stepping down to the SDA40 yields 628.3 N of push force at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N. The 50 mm bore pairs a PT1/4 port with a female M10x1.5 rod thread, and this specific SKU includes the male M18x1.5 thread option alongside the S magnet. Operating speed spans 30-500 mm/s.
A 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. Note that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a lock. To suspend a load securely without live pressure, incorporate an external rod lock or a pilot-operated check valve.
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, with a proof pressure of 1.5 MPa.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not act as a brake. An external rod lock or pilot-operated check valve is required to hold a load securely.
