Airtac SDA Ultra Thin Cylinder SDA100X75S
The AirTAC Airtac SDA Ultra Thin Cylinder SDA100X75S is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 75mm 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 SDA100X75S
The AirTAC SDA100X75S is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial envelope. Utilizing a riveted body assembly, it drastically reduces mounting depth compared to conventional round-body units, delivering a robust 3927 N push force at 0.5 MPa. The hard-anodized 100 mm bore houses a two-way piston seal, and the integrated -S piston magnet interfaces directly with AirTAC reed or electronic switches via body grooves for precise position detection.
Equipped with a 32 mm piston rod and PT3/8 air ports, this model handles substantial loads with a safe working capacity around 2356 N (roughly 60% of its 0.5 MPa output) and a vertical lift capability of approximately 200.2 kg at a 2:1 safety margin. Deceleration at stroke extremes relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorbers to prevent impact damage.

Where the Airtac SDA Ultra Thin Cylinder SDA100X75S Is Used
Automotive Stamping Press
Drives heavy blanking and forming dies on automotive assembly lines where the 3927 N extend force at 0.5 MPa securely shifts substantial tooling masses within tight machine footprints.
Palletizer Lift Station
Elevates loaded pallets in high-throughput packaging zones, utilizing the 32 mm rod and 200.2 kg vertical lift margin to raise goods efficiently before the fixed NBR bumper halts the stroke.
Injection Mold Extraction
Pushes thick-walled molded plastic components out of heavy tooling, relying on the built-in -S magnet and electronic switches to signal the robot picker that the part is fully ejected.
Is the Airtac SDA Ultra Thin Cylinder SDA100X75S the Right Cylinder?
Selecting this 100 mm bore provides maximum thrust for the SDA series, yielding 5497.8 N of extend force at 0.7 MPa. If your application requires less power, stepping down to the SDA80 offers 2513.3 N at 0.5 MPa, which may better suit medium-duty tasks without oversized plumbing. Confirm your ordering essentials: 100 mm bore, 75 mm stroke, PT3/8 port thread, female M18x1.5 rod end, and the built-in -S magnet.
Because the fixed NBR bumper only decelerates the piston near the end of travel and provides no braking capability, a plain SDA100X75S will drift if air pressure is lost or the valve is centered. If your machinery must hold a vertical load securely during an emergency stop or pressure drop, 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 SDA100X75S FAQ
This 100 mm 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 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and sustains speeds of 30-500 mm/s.
No, the SDA100X75S uses a fixed NBR bumper at each end to decelerate the piston. It is not an adjustable air cushion and does not act as a lock or brake. For high-speed or high-energy cycles, you should add an external shock absorber or slow the approach speed to prevent premature wear.
