About the Airtac SDA Ultra Thin Cylinder SDA100X75SH
The AirTAC SDA100X75SH is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted assembly reduces overall length compared to conventional round-body units, yielding a substantial 3927 N push force at 0.5 MPa alongside a 32 mm piston rod. This specific configuration includes an -S internal magnet for position detection and -H fluororubber (FKM) seals for enhanced thermal and oil resistance.
End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers are advised for high-energy 75 mm strokes. The body features integrated grooves compatible with AirTAC reed or electronic switches. Because the end stops only slow the piston near travel limits, an external rod lock or pilot-operated check valve is required to hold a load securely if air pressure is lost.

Where the Airtac SDA Ultra Thin Cylinder SDA100X75SH Is Used
Automotive Stamping Press
Drives heavy blank holder pins in an automotive panel stamping line, utilizing the 5497.8 N extend force at 0.7 MPa to secure sheet metal during deep draw operations.
Palletizer Head Actuator
Deploys a mechanical gripper head on a robotic palletizer, where the 3524.9 N retract force at 0.5 MPa reliably lifts corrugated cartons within tight vertical machine envelopes.
Injection Mold Ejector
Pushes thick-sectioned injection molded plastic parts off a tool face, relying on the 32 mm rod and FKM seals to withstand elevated ambient shop temperatures.
Is the Airtac SDA Ultra Thin Cylinder SDA100X75SH the Right Cylinder?
Selecting this 100 mm bore provides a safe working load of roughly 2356 N (about 60% of the 3927 N figure at 0.5 MPa), translating to a vertical lift capacity of approximately 200.2 kg with 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 body series. When ordering, confirm the 75 mm stroke, PT3/8 port, built-in magnet, female M18x1.5 rod thread, and FKM seal 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 SDA100X75SH FAQ
This double-acting 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. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and travels at 30-500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-speed 75 mm strokes, adding an external shock absorber is recommended. Furthermore, it does not hold position naturally on air loss; the piston drifts, so an external rod lock or pilot-operated check valve is necessary for secure load holding.
