About the Airtac SDA Ultra Thin Cylinder SDA100X120B
The AirTAC SDA100X120B is a double-acting, single-rod compact cylinder engineered to deliver substantial force within a minimal axial footprint. By utilizing a riveted assembly that integrates the barrel, rear cover, piston, and rod, this unit achieves a much shorter overall length than conventional round-body actuators, saving valuable machine mounting depth. It provides a robust 3927 N of push force and 3524.9 N of pull force at 0.5 MPa.
This specific configuration includes a male M26x1.5 threaded piston rod end for secure mechanical coupling to your load, paired with a substantial 32 mm rod diameter to minimize deflection. The bore features a hard-anodized surface for extended wear life. Deceleration at the stroke extremes is handled by a fixed NBR bumper, which absorbs end-stop impact rather than relying on a field-adjustable air cushion. Note that this SKU is supplied without a piston magnet and therefore cannot host sensing switches.

Where the Airtac SDA Ultra Thin Cylinder SDA100X120B Is Used
Stamping Press Ejection
Provides the heavy push force required to eject thick metal blanks from a stamping die, utilizing the male M26x1.5 rod end to secure a rugged tooling attachment.
Heavy-Duty Material Straightening
Applies up to 3927 N of extend force at 0.5 MPa to flatten or align structural steel components in an automated fabrication line.
Palletizer Lift Station
Handles the vertical lifting of loaded pallets in a compact gantry, where the short riveted body significantly reduces the required overhead clearance.
Is the Airtac SDA Ultra Thin Cylinder SDA100X120B the Right Cylinder?
Selecting this 100 mm bore actuator involves evaluating your spatial constraints against force requirements. If your application demands less thrust, stepping down to the SDA80 provides 2513.3 N of push at 0.5 MPa; conversely, the SDA100 represents the maximum standard bore in this series, yielding a theoretical maximum output of 801 kgf at 1.0 MPa. With a 120 mm stroke, this model operates near the 130 mm standard stroke ceiling for this bore size, making it ideal for high-force, short-travel tasks.
When integrating this cylinder, remember that a standard double-acting unit cannot maintain its position or hold a load if air pressure is lost or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the motion near the stroke end without acting as a mechanical lock. If your machinery requires strict position holding, you must incorporate an external rod lock or a pilot-operated check valve. Ensure your ordering essentials match this SKU: 100 mm bore, 120 mm stroke, PT3/8 ports, male M26x1.5 rod thread, and no sensor 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 SDA100X120B FAQ
This double-acting cylinder generates a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, the push increases to 5497.8 N and the pull to 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, has a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
This specific SKU lacks the -S option, meaning it has no piston magnet and cannot accept reed or electronic switches. Additionally, it uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber or slow down the approach speed.
