The AirTAC AirTAC SDA63X75SB Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm 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 SDA63X75SB is a double-acting, single-rod compact cylinder engineered to deliver 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. Its riveted body assembly significantly reduces axial mounting depth, providing a smaller machine footprint compared to traditional round-body alternatives. The unit includes a built-in piston magnet for position sensing and a male M18x1.5 threaded rod end for secure load coupling.
This model features a 63 mm bore, a 75 mm stroke, and a 20 mm piston rod. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorption. The integrated magnet supports AirTAC reed or electronic switches mounted directly into the body grooves.

Drives ejection pins on a 150-ton injection molding press, utilizing the 1558.6 N extend force to reliably strip finished plastic parts from the tool cavity.
Raises loaded machining pallets vertically, handling an approximate 79.4 kg payload with a 2:1 safety factor before transferring the fixture to the next CNC station.
Deploys a 75 mm stroke to fold heavy cardboard carton flaps in a continuous packaging line, where the fixed NBR bumper absorbs the end-stop impact at operating speeds.
When sizing this actuator, stepping down to the SDA50 yields 981.7 N of push force at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N. For this SDA63X75SB configuration, the computed safe working load is approximately 935 N (60% of the 0.5 MPa rating), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. Be aware that a standard compact cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; maintaining vertical loads requires an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 63 mm bore, 75 mm stroke, PT1/4 port, male M18x1.5 rod thread, and the integrated magnet.
Quick checklist
This double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, and 2182.1 N push with 1962.2 N pull at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa and a proof pressure of 1.5 MPa.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a braking lock; high-speed applications may need external shock absorbers. Because this unit includes the -S magnet, you can mount AirTAC reed or electronic switches in the body grooves for precise position detection.
