Airtac SDA Ultra Thin Cylinder SDA100X80B
The AirTAC Airtac SDA Ultra Thin Cylinder SDA100X80B is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 80mm 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 SDA100X80B
The AirTAC SDA100X80B is a double-acting, single-rod compact cylinder engineered to deliver substantial thrust within a minimal axial footprint. By utilizing a riveted assembly that joins the barrel, rear cover, piston, and rod, this unit achieves an exceptionally short overall length compared to conventional round-body designs, saving valuable machine mounting depth. At 100 mm bore, it provides 3927 N of push force and 3524.9 N of pull force at 0.5 MPa.
This specific configuration includes a male-thread piston rod end (M26x1.5) for secure mechanical load coupling, paired with a robust 32 mm rod diameter to handle high stress. The bore features a hard-anodized inner wall and a two-way piston seal. End-stop deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy cycling. Because this SKU lacks the -S magnet option, it cannot host magnetic position sensors.

Where the Airtac SDA Ultra Thin Cylinder SDA100X80B Is Used
Automotive Stamping Press
Drives heavy blanking and forming dies on automotive assembly lines, utilizing the 3927 N push force to shape sheet metal components reliably within a confined press footprint.
Plastic Injection Mold Ejection
Ejects dense molded plastic parts from heavy tooling, where the male M26x1.5 rod end threads securely into the ejector plate to prevent separation during high-force retraction.
Palletizer Lift Station
Raises heavy product layers in end-of-line packaging machinery, providing the necessary lifting power for 200 kg loads while maintaining a short retracted length to minimize tower height.
Is the Airtac SDA Ultra Thin Cylinder SDA100X80B the Right Cylinder?
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA80 yields 2513.3 N of push at 0.5 MPa, whereas this SDA100 provides 3927 N, and represents the largest standard bore in the series with a theoretical maximum output of 801 kgf at 1.0 MPa. Based on the 0.5 MPa figures, a safe working load is approximately 2356 N (about 60% of capacity), which translates 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, male M26x1.5 rod thread, and no sensor magnet. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates the stroke end and does not function as a locking brake. To suspend a load safely without live pressure, 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 SDA100X80B FAQ
This 100 mm bore 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 and 1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No, this SKU does not have adjustable air cushions; it relies on a fixed NBR bumper at each end to decelerate the stroke, so external shock absorbers are recommended for high-speed operations. Additionally, it lacks the -S magnet option, meaning it cannot support reed or electronic switches, and it features a male M26x1.5 threaded rod end instead of the default female thread.
