About the Airtac SDA Ultra Thin Cylinder SDA100X15S
The AirTAC SDA100X15S is a double-acting single-rod compact cylinder engineered for heavy-duty tasks within a minimal axial footprint. Utilizing a short riveted body assembly, it drastically reduces mounting depth compared to conventional round-body units, fitting seamlessly into tight machine spaces. At 100 mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, driven through a PT3/8 port.
This unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. Travel termination relies on a fixed NBR bumper at each end rather than an adjustable air cushion, effectively decelerating the 15 mm stroke. The 32 mm piston rod features a female M18x1.5 thread end, ensuring robust load coupling for high-energy cycles.

Where the Airtac SDA Ultra Thin Cylinder SDA100X15S Is Used
Stamping Press Ejection
Provides the intense 3927 N push force required to knock heavy stamped metal panels out of progressive dies within a confined press enclosure.
Injection Mold Separation
Utilizes its short 15 mm stroke and massive 801 kgf peak capacity to break initial vacuum suction on large plastic injection molded parts for robotic extraction.
Palletizer Stopper Gate
Acts as a high-force physical stop barrier in automated palletizing lines, securely halting fully loaded pallets via its 32 mm diameter rod.
Is the Airtac SDA Ultra Thin Cylinder SDA100X15S the Right Cylinder?
Selecting this 100 mm bore model provides a massive theoretical output of 801 kgf at 1.0 MPa, with a computed safe working load around 2356 N (roughly 60% of the 0.5 MPa push rating) and a vertical lift capacity near 200.2 kg using a 2:1 safety margin. If your application requires less force, stepping down to the SDA80 yields 2513.3 N at 0.5 MPa; as the largest standard size, stepping up would require a different cylinder series. When ordering, confirm the 100 mm bore, 15 mm stroke, PT3/8 port, female M18x1.5 rod thread, and the -S magnet option.
Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only absorbs end-of-stroke impacts and acts as neither a lock nor a brake. If your machinery must hold a vertical load safely without live pressure, 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 SDA100X15S FAQ
This double-acting cylinder delivers 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 force is 801 kgf at the 1.0 MPa maximum operating pressure.
It uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. The built-in magnet supports AirTAC reed or electronic switches for position sensing, but the cylinder will drift on air loss and requires an external rod lock to hold loads safely.
