About the Airtac SDA Ultra Thin Cylinder SDA100X80S
The AirTAC SDA100X80S is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. It generates a substantial 3927 N push force at 0.5 MPa, supported by a robust Ø32 mm piston rod and PT3/8 air ports. The riveted body design significantly reduces overall mounting depth compared to standard round-body actuators, making it ideal for tight machinery layouts.
This unit includes a built-in piston magnet (-S) for direct compatibility with AirTAC reed or electronic switches along its body grooves. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be added for high-energy loads. Operating efficiently between 0.15-1.0 MPa, it provides a safe working load of approximately 2356 N (about 60% of the 0.5 MPa rating) and can vertically lift roughly 200.2 kg with a 2:1 safety margin.

Where the Airtac SDA Ultra Thin Cylinder SDA100X80S Is Used
Stamping Press Feeders
Drives heavy metal blanks into progressive dies, utilizing the 3927 N extend force to push thick gauge materials where a shorter 80 mm stroke is required.
Pallet Elevators
Lifts loaded pallets vertically in compact packaging cells, safely handling the 200.2 kg dynamic load capacity without consuming excessive floor space.
Heavy Crate Lid Presses
Secures heavy wooden crate lids during nailing or banding operations, relying on the rigid 32 mm rod to resist side-loading while clamping securely.
Is the Airtac SDA Ultra Thin Cylinder SDA100X80S the Right Cylinder?
When sizing this 100 mm bore actuator, compare its 3927 N push at 0.5 MPa against the smaller SDA80, which yields 2513.3 N under identical pressure. As the largest available bore in this series, there is no larger standard option; if 3927 N is insufficient, you will need to explore alternative multi-cylinder or guided setups. Remember that a plain compact cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock or pilot-operated check valve is required to hold a load securely.
Confirm your ordering essentials: 100 mm bore, 80 mm stroke, PT3/8 port thread, female M18x1.5 rod end (or male M26x1.5 if specified), and the built-in magnet for position sensing.
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 SDA100X80S FAQ
This double-acting cylinder delivers 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 within a pressure range of 0.15-1.0 MPa at speeds between 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 operations, you should add external shock absorbers. Additionally, it does not hold its position if air is lost—the piston will drift—so an external rod lock or pilot-operated check valve is necessary for load holding.
