About the Airtac SDA Ultra Thin Cylinder SDA100X85S
The AirTAC SDA100X85S is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted body assembly significantly reduces overall mounting depth compared to conventional round-body units, delivering a substantial 3927 N push force at 0.5 MPa alongside a robust 32 mm piston rod.
This 100 mm bore model includes a built-in piston magnet (-S) for direct integration with AirTAC reed or electronic switches via the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach speed or utilize external shock absorbers during high-energy cycles.

Where the Airtac SDA Ultra Thin Cylinder SDA100X85S Is Used
Stamping Press Ejection
Provides the heavy push force needed to eject thick metal blanks from progressive stamping dies, utilizing the 85 mm stroke to clear the press bed rapidly.
Palletizer Lift Arm
Raises heavy palletized goods in end-of-line packaging machinery where the short riveted body depth prevents interference with adjacent conveyor structures.
Injection Mold Separation
Delivers the robust actuation required to separate large injection-molded automotive panels from heavy tooling, relying on the 32 mm rod to handle high side-load resistance.
Is the Airtac SDA Ultra Thin Cylinder SDA100X85S the Right Cylinder?
Selecting this 100 mm bore provides a massive 801 kgf maximum theoretical push at 1.0 MPa. If your application requires less force, stepping down to the SDA80 yields 2513.3 N at 0.5 MPa, while the SDA100 represents the top tier of this series. A computed safe working load is approximately 2356 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of roughly 200.2 kg with a 2:1 safety margin.
When ordering, confirm the 100 mm bore, 85 mm stroke, PT3/8 porting, female M18x1.5 rod-end thread, and the required -S magnet. Remember 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 cannot hold a load. For suspended loads, specify 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 SDA100X85S FAQ
This 100 mm bore model uses 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.
No, a standard double-acting cylinder will drift if air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not function as a locking brake. An external rod lock or pilot-operated check valve is required for secure load holding.
