The AirTAC AirTAC SDA50X130S Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 130mm 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 SDA50X130S 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 securely joins the barrel, rear cover, piston, and rod, drastically reducing axial mounting depth compared to conventional round-body units. The 50 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable low-friction operation across the 30-500 mm/s speed range.
This specific configuration includes a 130 mm stroke and a built-in piston magnet (the -S option) for position detection. The body is machined with peripheral grooves designed to accept AirTAC magnetic reed or electronic switches. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, which keeps the overall length minimal while absorbing impact energy.

Raises and lowers a 50 kg transfer carriage in end-of-line packaging machinery, utilizing the 130 mm stroke to clear the conveyor path during product handoff.
Drives the secondary folding arm on a case erector, applying 981.7 N of push at 0.5 MPa to tuck heavy corrugated flaps before tape application.
Ejects stamped metal brackets from a 40-ton press bed, where the short riveted body saves critical axial depth in the confined die space.
Selecting this 50 mm bore model provides a theoretical maximum push of 200 kgf at 1.0 MPa, translating to a safe working load of roughly 589 N (about 60% of the 981.7 N output at 0.5 MPa) or a vertical lift capacity near 50 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA40 yields 628.3 N at 0.5 MPa; conversely, stepping up to the SDA63 provides 1558.6 N. Keep in mind that a plain compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load. For vertical or suspended loads, integrate an external rod lock or a pilot-operated check valve. When ordering, confirm the 50 mm bore, 130 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the required -S magnet.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides 981.7 N of push force and 824.7 N of pull force. At 0.7 MPa, the push increases to 1374.4 N and the pull to 1154.5 N. The theoretical maximum push is 200 kgf at the maximum operating pressure of 1.0 MPa.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. The included -S magnet allows you to mount AirTAC reed or electronic switches directly into the body grooves for precise end-position detection.
