About the Airtac SDA Ultra Thin Cylinder SDA100X80H
The AirTAC SDA100X80H is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted body assembly significantly reduces overall length compared to conventional round-body units, saving valuable machine space while delivering a robust 3927 N push force at 0.5 MPa. This specific H-series configuration utilizes fluororubber (FKM) seals, providing enhanced thermal stability and oil resistance for demanding operating environments.
The unit features a hard-anodized 100 mm bore and a substantial 32 mm piston rod. End-stopping is handled by fixed NBR bumpers rather than adjustable air cushions, meaning high-energy cycles may require external shock absorbers. Because this SKU lacks the -S option, it has no piston magnet and cannot support magnetic position sensing.

Where the Airtac SDA Ultra Thin Cylinder SDA100X80H Is Used
Stamping Press Ejection
Provides the high 3927 N extend force needed to knock heavy stamped metal panels out of progressive die tooling, with FKM seals surviving the heat from continuous press operation.
Palletizer Lift Station
Raises loaded pallets in compact end-of-line packaging machinery where axial depth is restricted, safely handling vertical loads up to 200.2 kg with a 2:1 safety margin.
Heavy Carton Sealing
Drives the sealing head pressure mechanism on automated case erectors, utilizing the 32 mm rod to maintain rigidity and the short body to fit within tight conveyor framework.
Is the Airtac SDA Ultra Thin Cylinder SDA100X80H the Right Cylinder?
When sizing this actuator, consider stepping down to the SDA80, which provides 2513.3 N of push force at 0.5 MPa, or utilize this 100 mm bore as the maximum capacity within the SDA series. Based on the 0.5 MPa output, the safe working load is approximately 2356 N (about 60% of capacity), translating to a vertical lift capability of roughly 200.2 kg with a 2:1 safety margin. Confirm your ordering essentials: 100 mm bore, 80 mm stroke, PT3/8 port, female M18x1.5 rod thread, and FKM seals.
Remember that a standard compact cylinder cannot hold a load if air pressure is lost or the directional valve is centered. The piston will drift, and the fixed rubber bumper only decelerates the stroke near its end without acting as a mechanical lock. For vertical or suspended loads, you must integrate an external rod lock or a pilot-operated check valve.
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 SDA100X80H FAQ
This 100 mm bore 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 and 1.0 MPa, with a speed range of 30-500 mm/s.
It relies on fixed NBR bumpers at each end to decelerate the piston, which are not adjustable air cushions, so high-speed applications may need external shock absorbers. This specific SKU lacks a piston magnet, meaning it cannot accept reed or electronic switches unless you switch to the -S variant.
