Airtac SDA Ultra Thin Cylinder SDA100X150S
The AirTAC Airtac SDA Ultra Thin Cylinder SDA100X150S is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 150mm 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.

About the Airtac SDA Ultra Thin Cylinder SDA100X150S
The AirTAC SDA100X150S is a double-acting, single-rod compact cylinder engineered to deliver substantial force within a minimal axial footprint. By utilizing a short riveted body assembly rather than a conventional long round-body design, it significantly reduces mounting depth in tight machinery spaces. At 0.5 MPa, this 100mm bore unit generates 3927 N of push force and 3524.9 N of pull force, with a robust 32mm piston rod handling the load transfer.
This specific configuration includes a built-in piston magnet (-S) for direct compatibility with AirTAC reed or electronic switches, which seat neatly into the machined grooves wrapping the cylinder body. The 150mm stroke exceeds the 130mm maximum standard stroke for this bore size, classifying it as a made-to-order variant. End-of-travel deceleration is managed strictly by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should incorporate external shock absorbers if cycling at high speeds or driving heavy masses.

Where the Airtac SDA Ultra Thin Cylinder SDA100X150S Is Used
Injection Mold Ejection
Drives heavy ejector pins in automotive plastic molding presses where the 3927 N push force at 0.5 MPa reliably strips large bumper fascias from the tool cavity.
Stamping Press Feed
Actuates heavy-duty feed clamps in a sheet metal stamping line, utilizing the 32mm rod and 150mm stroke to advance thick gauge steel blanks into the die.
Pallet Dispenser Pusher
Indexes empty wooden pallets into a high-speed packaging conveyor, relying on the compact riveted body to fit within the tight structural framework of the depalletizer.
Is the Airtac SDA Ultra Thin Cylinder SDA100X150S the Right Cylinder?
When sizing this model, evaluate your force requirements carefully. Stepping down to the SDA80 yields a 2513.3 N push at 0.5 MPa, which may suffice for lighter duties, whereas this SDA100 provides 3927 N. As the largest bore in the SDA series, there is no larger step-up option within this family. A practical computed insight for the 100mm bore is a safe working load of roughly 2356 N (about 60% of the 0.5 MPa push figure), translating to a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin.
Because a standard double-acting cylinder does not inherently hold its position upon air loss or valve centering, the piston will drift and the fixed NBR bumper only decelerates it near the stroke end without acting as a mechanical lock. If your application requires suspended load holding, you must integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 100mm bore, 150mm non-standard stroke, PT3/8 port, female M18x1.5 rod thread, and the -S magnet option.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDA Ultra Thin Cylinder SDA100X150S FAQ
This 100mm bore double-acting cylinder generates a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, the push increases to 5497.8 N. The theoretical maximum push is 801 kgf at the 1.0 MPa operating pressure limit, with a proof pressure of 1.5 MPa.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. Because this 150mm stroke is a non-standard made-to-order length, adding an external shock absorber is highly recommended to manage the kinetic energy of the 32mm rod at high speeds.
