The AirTAC AirTAC SDA100X65S Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 65mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA100X65S is a double-acting, single-rod compact cylinder engineered for heavy-duty pneumatic tasks within a minimal axial footprint. Its riveted assembly integrates the barrel, rear cover, piston, and 32 mm rod to deliver a substantial 3927 N of push force at 0.5 MPa, extending to 5497.8 N at 0.7 MPa. This space-efficient architecture provides a significant depth advantage over conventional round-body units when mounting room is restricted.
This 100 mm bore unit features PT3/8 ports and includes a built-in piston magnet (-S) for direct integration with AirTAC reed or electronic switches via the body grooves. The internal stroke termination relies on a fixed NBR bumper to decelerate the end stop rather than an adjustable air cushion. Operating efficiently between 30-500 mm/s, it handles a safe working load of approximately 2356 N (about 60% of the 0.5 MPa push figure), translating to a vertical lift capacity of roughly 200.2 kg with a 2:1 safety margin.

Provides the robust 3927 N extension force needed to eject dense plastic parts from injection molding machinery, utilizing the 65 mm stroke to clear the tooling plate efficiently.
Drives downward pressing actions in automated bearing insertion stations, where the fixed NBR bumper absorbs the impact of the 200.2 kg equivalent load at the end of travel.
Indexes thick sheet metal into mechanical presses, relying on the 32 mm rod and male M26x1.5 thread to maintain rigid coupling under high inertial loading.
When sizing this actuator, evaluate your force margins both ways. Stepping down, the SDA80 provides 2513.3 N of push at 0.5 MPa, which may suffice for lighter payloads while saving valuable machine space. Stepping up is not applicable as this is the largest bore in the SDA family, so if your application requires more than the 3927 N generated here, you will need to explore alternative multi-cylinder setups or larger ISO profile series. For this specific model, confirm your ordering essentials: 100 mm bore, 65 mm stroke, PT3/8 porting, female M18x1.5 rod thread, and the required -S magnet option. If the machinery must maintain vertical position during air loss or valve centering, note that this standard actuator will drift; an external rod lock or pilot-operated check valve is required to secure the load.
Quick checklist
This 100 mm bore cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa, increasing to 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push force is 801 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa and a proof pressure of 1.5 MPa.
No, a standard SDA cylinder will drift if air 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 locking brake. To maintain a vertical load without live pressure, you must install an external rod lock or a pilot-operated check valve.
