About the Airtac SDA Ultra Thin Cylinder SDA100X35H
The AirTAC SDA100X35H is a double-acting single-rod compact cylinder engineered for heavy-duty pneumatic actuation. It generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, scaling up to a theoretical maximum of 801 kgf at 1.0 MPa. This unit features a fluororubber (FKM) seal variant, providing enhanced resistance to higher temperatures and oily environments compared to standard NBR seals.
Designed with a short riveted body, it drastically reduces axial mounting depth where a conventional round-body or profile cylinder would not fit. The 32 mm piston rod utilizes an M18x1.5 female thread for secure load coupling, while the PT3/8 port ensures adequate airflow for the 100 mm bore. End-stopping is handled by a fixed NBR bumper that decelerates the piston near stroke limits; it is not an adjustable air cushion, so high-energy cycles may require external shock absorbers.

Where the Airtac SDA Ultra Thin Cylinder SDA100X35H Is Used
Stamping Press Ejection
Provides the robust 3927 N push force required to eject heavy formed metal panels from a stamping press bed, with FKM seals surviving elevated ambient heat.
Palletizer Lift Station
Handles the vertical lifting of dense industrial pallets, utilizing the 32 mm rod to manage substantial downward weight without buckling during transit.
Heavy Crate Sealing
Applies high clamping pressure to hold large wooden crates stationary while automated nailing or strapping machinery secures the shipping container.
Is the Airtac SDA Ultra Thin Cylinder SDA100X35H the Right Cylinder?
When sizing this 100 mm bore actuator, stepping down to the SDA80 yields 2513.3 N of push force at 0.5 MPa, which may suffice if your payload is lighter and you need a narrower footprint. If 3927 N at 0.5 MPa is insufficient, this 100 mm bore is the largest available in the SDA series. A computed insight for this model indicates a safe working load of roughly 2356 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of approximately 200.2 kg with a 2:1 safety margin. To finalize your order, confirm the 100 mm bore, 35 mm stroke, PT3/8 port, female rod thread, and FKM seal. Note that this plain cylinder does not hold its position if air pressure is lost; the piston will drift, so applications requiring load holding need an external rod lock or 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 SDA100X35H FAQ
This double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push at 0.7 MPa. The theoretical maximum push force is 801 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds from 30-500 mm/s.
No, this specific SKU lacks the internal piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option to add a magnet for sensing. Additionally, end stopping relies on a fixed NBR bumper rather than an adjustable air cushion.
