Airtac SDA Ultra Thin Cylinder SDA100X35S
The AirTAC Airtac SDA Ultra Thin Cylinder SDA100X35S is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 35mm 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 SDA100X35S
The AirTAC SDA100X35S 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. At 0.5 MPa, this 100mm bore unit generates 3927 N of push force and 3524.9 N of pull force, extending to a theoretical maximum of 801 kgf at 1.0 MPa.
This specific configuration includes a built-in piston magnet (the -S option) for direct compatibility with AirTAC reed or electronic switches, which seat neatly into the grooves around the body. The 32mm piston rod utilizes a female M18x1.5 thread, and the air supply connects via a PT3/8 port. Deceleration at the stroke ends is handled by a fixed NBR bumper, which is not an adjustable air cushion, meaning external shock absorbers should be considered for high-energy loads moving at the 30-500 mm/s speed range.

Where the Airtac SDA Ultra Thin Cylinder SDA100X35S Is Used
Automotive Stamping Press
Drives heavy lower-die clamps in automotive stamping presses, utilizing the 5497.8 N extend force at 0.7 MPa to secure dies firmly against vibration during high-speed blanking operations.
Palletizer Head Actuator
Actuates the mechanical gripper head on heavy-duty robotic palletizers, where the 32mm rod and 35mm stroke provide the rapid, robust extension needed to release large corrugated boxes onto outbound freight conveyors.
Heavy Plate Straightener
Applies localized bending pressure in structural steel plate straightening fixtures, taking advantage of the 801 kgf maximum capacity to flatten thick weldments without requiring a bulky profile cylinder.
Is the Airtac SDA Ultra Thin Cylinder SDA100X35S the Right Cylinder?
Selecting this 100mm bore model provides a safe working load of approximately 2356 N, or a vertical lift capacity of roughly 200.2 kg when applying a 2:1 safety margin to the 3927 N push force at 0.5 MPa. If your application requires slightly less force, stepping down to the SDA80 yields 2513.3 N of push at 0.5 MPa; as the largest bore in the SDA series, there is no larger standard option available. When ordering, confirm the 100mm bore, 35mm stroke, PT3/8 port, the female M18x1.5 rod thread, and the required -S magnet for position sensing.
Keep in mind that a standard double-acting cylinder like this does not hold its position if air pressure is lost or the directional valve is centered, as the piston will drift and the fixed bumper only decelerates the stroke near the end without acting as a lock. If your machinery demands fail-safe load holding, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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 SDA100X35S FAQ
The SDA100X35S 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 force is 5497.8 N and the pull force is 4934.8 N. The theoretical maximum push force is 801 kgf at the 1.0 MPa operating pressure limit.
The cylinder uses a fixed NBR bumper at each end to decelerate the piston near the stroke extremes, but it is not an adjustable air cushion and high-speed loads may require external shock absorbers. Additionally, it does not hold its load if air is lost; the piston drifts, so an external rod lock or pilot-operated check valve is required for fail-safe holding.
