The AirTAC AirTAC SDA63X90S 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 SDA63X90S is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its riveted assembly securely joins the barrel, rear cover, piston, and rod, drastically reducing axial mounting depth where a conventional round-body unit would simply not fit. The 63 mm bore features a hard-anodized inner wall and a two-way piston seal for prolonged operational life.
Equipped with a built-in piston magnet (the -S option), this model is ready for AirTAC reed or electronic switches via the body grooves. It uses a PT1/4 port and a 20 mm rod to handle the 90 mm stroke. End-of-travel energy is managed strictly by a fixed NBR bumper, which decelerates the piston but is not a field-adjustable air cushion.

Secures heavy cast iron engine blocks onto machining centers, utilizing the 1558.6 N extend force to maintain rigid positioning against high spindle torque.
Actuates the release mechanism in automated wooden pallet dispensers, where the short riveted body saves valuable axial space within tight conveyor framing.
Drives vertical product elevators in material handling lines, safely lifting loads up to 79.4 kg with a 2:1 safety margin while operating at speeds between 30-500 mm/s.
When sizing this unit, consider stepping down to the SDA50, which yields 981.7 N of push at 0.5 MPa, or moving up to the SDA80, which provides 2513.3 N at the same pressure. For this 63 mm bore, the computed safe working load is approximately 935 N (about 60% of the 1558.6 N figure), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. To finalize your order, confirm the 63 mm bore, 90 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the required -S magnet.
Keep in mind that a standard compact cylinder will not hold a load if air pressure drops or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the stroke near its limits and does not act as a locking brake. If your application requires static holding, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates a push force of 1558.6 N and a pull force of 1401.5 N at 0.5 MPa. At 0.7 MPa, the push increases to 2182.1 N. The theoretical maximum push is 318 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
No, the SDA63X90S uses a fixed NBR bumper at each end to decelerate the piston; it is not an adjustable air cushion. Additionally, it cannot hold a load if air is lost or the valve is centered, as the piston will drift. For load holding, an external rod lock or pilot-operated check valve is required.
