Airtac SDA Ultra Thin Cylinder SDA100X140
The AirTAC Airtac SDA Ultra Thin Cylinder SDA100X140 is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 140mm 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 SDA100X140
The AirTAC SDA100X140 is a double-acting single-rod compact cylinder engineered to deliver a robust 3927 N push force at 0.5 MPa. Featuring a hard-anodized 100 mm bore and a substantial 32 mm piston rod, this riveted-body actuator minimizes axial mounting depth where a conventional round-body unit would simply not fit. Because the 140 mm stroke exceeds the 130 mm standard maximum for this bore size, this specific configuration is treated as a non-standard, made-to-order item.
This model relies on a fixed NBR bumper at each end to decelerate the stroke end, meaning it is not an adjustable air cushion and external shock absorbers should be added for high-energy cycles. Operating at speeds between 30-500 mm/s, the unit utilizes PT3/8 ports and a female M18x1.5 rod-end thread. Without the -S magnet option, this SKU cannot host magnetic switches; position sensing requires that variant.

Where the Airtac SDA Ultra Thin Cylinder SDA100X140 Is Used
Injection Mold Ejection
Provides high-force ejection of dense plastic parts from injection molding tools where minimal axial depth behind the mold plate is critical.
Heavy Press Fitment
Drives robust press operations for seating large automotive bearings, utilizing the 5497.8 N extend force available at 0.7 MPa.
Pallet Lifter Stops
Acts as a heavy-duty mechanical stop or positioning block in automated pallet handling lines, absorbing significant kinetic energy at stroke end.
Is the Airtac SDA Ultra Thin Cylinder SDA100X140 the Right Cylinder?
When sizing this actuator, consider stepping down to the SDA80, which provides 2513.3 N of push force at 0.5 MPa, as the SDA100 represents the largest bore in this compact series. A computed safe working load for this 100 mm bore is approximately 2356 N (about 60% of the 3927 N figure at 0.5 MPa), allowing a vertical lift of roughly 200.2 kg with a 2:1 safety margin. Keep in mind a plain compact cylinder does not hold its load on air loss or when the valve is centred—the piston drifts and the fixed bumper only decelerates near stroke end, so an external rod lock or pilot-operated check valve is required to hold a load. To order, confirm the 100 mm bore, 140 mm non-standard stroke, PT3/8 port, female rod thread, and no magnet.
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 SDA100X140 FAQ
This 100 mm bore double-acting cylinder generates 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, with a proof pressure of 1.5 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the rod near the stroke end and does not function as a lock or brake. An external rod lock or pilot-operated check valve is required for position holding.
