About the Airtac SDA Ultra Thin Cylinder SDA100X20SH
The AirTAC SDA100X20SH is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted assembly significantly reduces overall length compared to conventional round-body units, delivering a substantial 3927 N push force at 0.5 MPa. This specific configuration includes an H designation, utilizing fluororubber (FKM) seals for enhanced thermal and oil resistance, alongside a built-in piston magnet for position sensing.
Constructed with a hard-anodized 100 mm bore and a robust 32 mm piston rod, it handles a safe working load of roughly 2356 N (about 60% of the 0.5 MPa push figure). The body incorporates grooves for AirTAC reed or electronic switches. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke end; it is not an adjustable air cushion, so high-energy cycles may require external shock absorbers.

Where the Airtac SDA Ultra Thin Cylinder SDA100X20SH Is Used
Injection Mold Ejection
Provides the high 3927 N breakout force needed to eject dense plastic parts from injection molding tools, where the compact riveted body fits tightly within mold platens.
Heavy Gauge Metal Stamping
Handles short 20 mm clamping strokes in power press operations, using its FKM seals to withstand elevated ambient heat generated near heavy gauge steel stamping stations.
Palletizer Lift Stations
Drives short vertical lifting motions in end-of-line palletizing equipment, moving approximately 200 kg loads vertically with a safe 2:1 force margin.
Is the Airtac SDA Ultra Thin Cylinder SDA100X20SH the Right Cylinder?
Selecting this 100 mm bore model provides a maximum theoretical push of 801 kgf at 1.0 MPa, with a vertical lift capacity around 200.2 kg using a 2:1 safety margin. If your application requires less force, stepping down to the SDA80 yields 2513.3 N at 0.5 MPa, making this 100 mm version the largest available option in the series. When ordering, confirm the 20 mm stroke, PT3/8 porting, female M18x1.5 rod-end thread, the S magnet option, and the H FKM seal variant.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure drops or the valve is centered—the piston will drift. If your machinery demands strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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 SDA100X20SH FAQ
This 100 mm bore cylinder features PT3/8 ports and a 32 mm rod. It generates a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, push is 5497.8 N and pull is 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion or a braking lock. The included S magnet allows tracking by AirTAC reed or electronic switches. For high-speed operations, adding an external shock absorber is advised to manage kinetic energy.
