Airtac SDA Ultra Thin Cylinder SDA100X20S
The AirTAC Airtac SDA Ultra Thin Cylinder SDA100X20S is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 20mm 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 SDA100X20S
The AirTAC SDA100X20S is a double-acting single-rod compact cylinder engineered for heavy-duty tasks within a minimal axial footprint. By utilizing a short riveted body that integrates the barrel, rear cover, piston, and rod, it drastically reduces mounting depth compared to conventional round-body units. In this 100 mm bore configuration, it generates a substantial 3927 N push and 3524.9 N pull at 0.5 MPa, supported by a robust Ø32 mm piston rod.
This specific model includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-stop deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or utilize external shock absorbers during high-energy cycles. Air connections use a PT3/8 port, and the unit operates reliably at speeds between 30-500 mm/s.

Where the Airtac SDA Ultra Thin Cylinder SDA100X20S Is Used
Injection Mold Ejection
Provides the heavy 3927 N extension force needed to eject dense plastic parts from large injection molding machines, capitalizing on the 20 mm short stroke to fit within tight mold platen areas.
Press Brake Tooling
Drives upper die tooling in light-duty metal forming presses where a 100 mm bore delivers the necessary impact without the axial length of an ISO 15552 profile cylinder.
Heavy Pallet Lifting
Lifts loaded pallets in automated packaging cells, safely handling vertical loads around 200.2 kg with a 2:1 margin while the fixed NBR bumper absorbs the end-stop shock.
Is the Airtac SDA Ultra Thin Cylinder SDA100X20S the Right Cylinder?
When sizing this actuator, consider stepping down to the SDA80, which yields 2513.3 N of push force at 0.5 MPa if your application requires less power. As the largest bore in the series, the SDA100 represents the maximum thrust tier available before moving to alternative body styles. Based on the 3927 N push figure at 0.5 MPa, the computed safe working load is roughly 2356 N (about 60% capacity), translating to a vertical lift capability of approximately 200.2 kg with a 2:1 safety margin.
Because a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centered, an external rod lock or pilot-operated check valve is necessary if the load must remain suspended. To finalize your order, confirm the 100 mm bore, 20 mm stroke, PT3/8 port, built-in magnet (S), and the female M18x1.5 rod-end thread (or male M26x1.5 if customized).
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 SDA100X20S FAQ
This 100 mm bore cylinder delivers 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 is 801 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a proof pressure of 1.5 MPa and a speed range of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-speed or high-energy cycles, adding an external shock absorber is advised. Furthermore, it will not hold a load if air is lost; the piston drifts, requiring an external rod lock or pilot-operated check valve for secure position holding.
