The AirTAC SDA63X90SH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 90mm 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 SDA63X90SH is a double-acting, single-rod compact cylinder engineered for substantial actuation tasks, delivering a push force of 1558.6 N and a pull force of 1401.5 N at 0.5 MPa. A short riveted assembly joins the barrel, rear cover, piston, and rod, drastically reducing axial mounting depth where a conventional round-body unit would not fit. The 63 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable service life.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, and an FKM fluororubber seal (-H) for enhanced thermal and oil resistance. It uses a 20 mm piston rod with a male M18x1.5 thread end, operating at speeds from 30 to 500 mm/s. End-stopping relies on a fixed NBR bumper that decelerates the stroke, rather than an adjustable air cushion.

Drives ejection pins on a 150-ton injection molding press, utilizing the 1558.6 N extend force to strip dense plastic parts from the tool cavity reliably.
Actuates a heavy-duty routing arm on a logistics sorting line, using the 90 mm stroke to push dense cartons weighing up to 79.4 kg onto secondary chutes.
Positions lower die rails on a sheet metal press brake, where the compact riveted body minimizes axial footprint and the FKM seals withstand elevated ambient heat.
When sizing this unit, consider stepping down to the SDA50, which provides 981.7 N of push force at 0.5 MPa, or moving up to the SDA80, which yields 2513.3 N at the same pressure. Keep in mind a standard SDA does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. To secure a suspended load, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 63 mm bore, 90 mm stroke, PT1/4 port, male M18x1.5 rod thread, magnetic switch ready, and FKM seals.
Quick checklist
At 0.5 MPa, the push force is 1558.6 N and the pull force is 1401.5 N. At 0.7 MPa, push is 2182.1 N and pull is 1962.2 N. The theoretical maximum push is 318 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa, and the operating temperature is -20 to +70 C.
It uses a fixed NBR bumper at each end to decelerate the piston; it is not an adjustable air cushion, so you should add an external shock absorber for high-energy cycles. The -S code means a magnet is built in for AirTAC reed or electronic switches, and the -H indicates FKM seals for higher temperature and oil resistance.
