The AirTAC AirTAC SDA63X100S Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 100mm 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 SDA63X100S 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 merges the barrel, rear cover, and piston into a highly shortened unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too bulky. The 63 mm bore houses a hard-anodized inner wall and a 20 mm piston rod, operating at speeds between 30 and 500 mm/s.
Because this unit carries the S option, it includes a built-in piston magnet designed to interface with AirTAC reed or electronic switches housed in the peripheral body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent impact damage.

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 and lowers a lightweight tooling plate in a palletizing cell, safely lifting 79.4 kg payloads vertically with a 2:1 safety margin.
Folds heavy corrugated carton flaps on a high-speed packaging line, where the fixed NBR bumper absorbs the end-stop impact during rapid 100 mm strokes.
When sizing this actuator, evaluate your force requirements carefully. Stepping down, the SDA50 provides 981.7 N of push at 0.5 MPa; stepping up, the SDA80 yields 2513.3 N at the same pressure. For the SDA63X100S specifically, the safe working load is approximately 935 N (about 60% of the 1558.6 N capacity), translating to a vertical lift capability of roughly 79.4 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered—the piston will drift, as the fixed bumper only decelerates near the stroke end and does not function as a locking brake. For suspended loads, an external rod lock or pilot-operated check valve is required.
To finalize your order, confirm the following configuration: 63 mm bore, 100 mm stroke, PT1/4 port, female M10x1.5 rod-end thread (with an optional male M18x1.5 available), and the built-in S magnet for position sensing.
Quick checklist
This double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, increasing to 2182.1 N push and 1962.2 N pull at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa and a temperature range of -20 to +70 C.
No, a standard SDA cylinder will drift if air pressure is lost or the directional valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not act as a brake. To maintain a vertical load safely, you must install an external rod lock or a pilot-operated check valve.
