Airtac SDA Ultra Thin Cylinder SDA100X140B
The AirTAC Airtac SDA Ultra Thin Cylinder SDA100X140B 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 SDA100X140B
The AirTAC SDA100X140B is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted assembly keeps the overall length exceptionally short, saving valuable machine depth where a conventional round-body actuator would be too bulky. At 100 mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, with a theoretical maximum output of 801 kgf at 1.0 MPa.
This specific SKU features a male M26x1.5 threaded piston rod end for robust mechanical coupling to your load. Because the 140 mm stroke exceeds the 130 mm maximum standard stroke for this bore size, this unit is provided as a non-standard, made-to-order configuration. End-stopping relies on a fixed NBR bumper to decelerate the piston rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. Note that this variant lacks a piston magnet and therefore cannot support position sensing.

Where the Airtac SDA Ultra Thin Cylinder SDA100X140B Is Used
Automotive Press Stamping
Drives heavy stamping dies and holding fixtures in automotive body-in-white assembly lines, utilizing the 3927 N push force to form sheet metal panels securely.
Heavy Profile Extrusion
Provides the substantial clamping thrust required to straighten and hold large aluminum extrusion profiles during cooling and cutting processes.
Palletizer Lift Stations
Actuates heavy-load lifting platforms in end-of-line palletizing machinery, where the 200.2 kg vertical lift capacity handles substantial packaged goods.
Is the Airtac SDA Ultra Thin Cylinder SDA100X140B the Right Cylinder?
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA80 provides 2513.3 N of push at 0.5 MPa, whereas this SDA100 delivers 3927 N. If your application demands the full 801 kgf maximum thrust, ensure your air supply can maintain 1.0 MPa without dropping below the 0.15 MPa minimum operating pressure. Factoring a 2:1 safety margin, the safe working load is approximately 2356 N, which translates to a vertical lift capacity of about 200.2 kg.
Confirm your ordering essentials: this SDA100X140B specifies a 100 mm bore, 140 mm non-standard stroke, PT3/8 port, and a male M26x1.5 rod thread. Be aware that a standard double-acting cylinder will drift and lose its position if air pressure is lost or the valve is centered; the fixed NBR bumper only decelerates the stroke end and does not function as a locking brake. If your machinery must hold a load safely without live pressure, 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 SDA100X140B FAQ
This 100 mm bore double-acting cylinder uses a PT3/8 air port. It generates 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, and a theoretical maximum push of 801 kgf at 1.0 MPa.
No, this specific SKU does not include the -S option, meaning it lacks a piston magnet and cannot be used with reed or electronic switches. Additionally, because the 140 mm stroke exceeds the 130 mm standard maximum, it is a made-to-order item, and its fixed NBR bumpers are not adjustable air cushions.
