About the Airtac SDA Ultra Thin Cylinder SDA100X30S
The AirTAC SDA100X30S is a double-acting, single-rod compact cylinder engineered for heavy-duty pneumatics within a minimal axial footprint. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, this unit achieves an exceptionally short overall length compared to conventional round-body designs. It yields a substantial 3927 N push force at 0.5 MPa, backed by a hard-anodized 100 mm bore and a robust 32 mm piston rod.
This specific configuration includes the S option, meaning a built-in piston magnet enables position detection via an AirTAC reed or electronic switch housed in the body grooves. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, effectively decelerating the stroke ends. For applications operating near the maximum 500 mm/s velocity, integrating an external shock absorber is advisable to manage kinetic energy.

Where the Airtac SDA Ultra Thin Cylinder SDA100X30S Is Used
Stamping Press Ejection
Provides the 3927 N push force required to knock heavy stamped metal panels out of progressive dies, where the short riveted body prevents interference with the press tooling.
Palletizer Lift Station
Handles vertical lifting of 200 kg industrial pallets in packaging lines, utilizing the 32 mm rod and built-in S magnet to trigger reed or electronic switches at the lift apex.
Injection Mold Core Pull
Shifts heavy mold cores in plastic injection machinery, benefiting from the 30 mm stroke and fixed NBR bumpers that absorb the sudden end-stop shock during rapid cycling.
Is the Airtac SDA Ultra Thin Cylinder SDA100X30S the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force requirements carefully. Stepping down, the SDA80 provides 2513.3 N of push at 0.5 MPa, which may suffice for lighter loads while further reducing envelope size. If the SDA100X30S is chosen, ensure your setup accommodates the PT3/8 air ports and the female M18x1.5 rod-end thread. The computed safe working load is approximately 2356 N (about 60% of the 3927 N figure at 0.5 MPa), allowing a vertical lift of roughly 200.2 kg with a 2:1 safety margin.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centered; the fixed bumper only softens the impact near the stroke end and does not function as a braking mechanism. To suspend a load securely without live pressure, you must incorporate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 100 mm bore, 30 mm stroke, PT3/8 port, S magnet, and female rod thread.
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 SDA100X30S FAQ
This 100 mm bore double-acting cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 5497.8 N. The theoretical maximum push force is 801 kgf at the 1.0 MPa operating pressure limit.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the piston. It is not an adjustable air cushion and cannot be field-tuned. For high-speed or high-energy loads, you should slow the approach speed or add an external shock absorber.
