Airtac SDA Ultra Thin Cylinder SDA100X15B
The AirTAC Airtac SDA Ultra Thin Cylinder SDA100X15B is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 15mm 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 SDA100X15B
The AirTAC SDA100X15B is a double-acting single-rod compact cylinder engineered for high-force duties within a minimal axial envelope. Utilising a riveted assembly of the barrel, rear cover, piston and rod, this unit saves substantial mounting depth compared to conventional round-body actuators. At 100 mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, driven through PT3/8 ports.
This specific SKU features a male M26x1.5 thread on the 32 mm piston rod for robust load coupling. End-stop energy is managed solely by a fixed NBR bumper, which decelerates the piston near stroke completion rather than acting as a lock or adjustable air cushion. Because this configuration lacks the -S magnet option, it cannot host reed or electronic switches for position sensing.

Where the Airtac SDA Ultra Thin Cylinder SDA100X15B Is Used
Injection Mold Platen Ejection
Provides the heavy 3927 N push stroke required to eject dense plastic parts from an injection molding press, where the short 15 mm travel and compact riveted body fit neatly into the mold platen void.
Heavy Gauge Metal Forming
Executes short, high-impact stamping and bending tasks on thick sheet metal, utilising the rigid 32 mm male-threaded rod end to secure heavy tooling without deflection.
Palletizer Stopper Gate
Acts as a robust physical stop gate in automated palletizing lines, throwing its 801 kgf maximum theoretical weight capacity against heavy loads to halt pallet movement securely.
Is the Airtac SDA Ultra Thin Cylinder SDA100X15B the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force requirements carefully. Stepping down to the SDA80 yields 2513.3 N of push at 0.5 MPa, whereas this SDA100X15B provides 3927 N, offering a safe working load of roughly 2356 N (about 60% of the 0.5 MPa figure) and a vertical lift capacity near 200.2 kg with a 2:1 safety margin. If your application demands the maximum 801 kgf theoretical output at 1.0 MPa, ensure your framework can handle the resulting stresses.
For ordering, confirm the 100 mm bore, 15 mm stroke, PT3/8 porting, and the -B male M26x1.5 rod thread. Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centred; the fixed bumper only softens the end of travel and does not function as a braking device. To suspend a load safely without live pressure, integrate 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 SDA100X15B FAQ
This 100 mm bore double-acting cylinder delivers a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, push increases to 5497.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa, and the speed range spans 30-500 mm/s.
No, it uses a fixed NBR bumper at each end to decelerate the stroke end, which is not a field-adjustable air cushion. For high-energy cycles, add an external shock absorber. Additionally, this specific SKU lacks the -S magnet, so it cannot support reed or electronic switches; you would need the -S variant for position sensing.
