About the Airtac SDA Ultra Thin Cylinder SDA100X120SB
The AirTAC SDA100X120SB is a double-acting, single-rod compact cylinder engineered for heavy-duty pneumatics within a minimal axial footprint. By utilizing a riveted assembly that merges the barrel, rear cover, piston and rod, this unit drastically reduces mounting depth compared to conventional round-body actuators. At its core, it generates a substantial 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, operating efficiently across a 30-500 mm/s speed range.
This specific configuration includes the -S option, equipping the piston with a built-in magnet for direct compatibility with AirTAC reed or electronic switches via the body's peripheral grooves. The -B option specifies a male M26x1.5 threaded piston rod end (instead of the default female M18x1.5) for robust mechanical coupling to your load. Deceleration at the stroke extremes is handled by a fixed NBR bumper, which absorbs end-stop impact but is not a field-adjustable air cushion.

Where the Airtac SDA Ultra Thin Cylinder SDA100X120SB Is Used
Stamping Press Ejection
Provides the heavy 3927 N push force required to eject thick steel blanks from a progressive stamping press die, utilizing the male M26x1.5 rod for secure tool mounting.
Palletizer Lift Station
Handles vertical lifting of 200 kg industrial pallet loads in packaging lines, where the compact riveted body saves critical vertical space without sacrificing actuation power.
Injection Mold Clamping
Delivers high-force clamping on auxiliary injection molding fixtures, relying on the built-in magnet and electronic switches to confirm mold closure before resin injection.
Is the Airtac SDA Ultra Thin Cylinder SDA100X120SB the Right Cylinder?
Selecting this 100mm bore actuator involves sizing both ways: if 3927 N push at 0.5 MPa exceeds your requirement, stepping down to the SDA80 provides 2513.3 N, whereas this SDA100 represents the maximum standard bore in the series with a theoretical 801 kgf max push at 1.0 MPa. When ordering, confirm the 100mm bore, 120mm stroke, PT3/8 port thread, the required -S magnetic sensor option, and the -B male M26x1.5 rod thread.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure drops or the control valve is centered; the piston will drift, and the fixed NBR bumper only decelerates near the stroke end without acting as a mechanical lock. If your application demands position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into your 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 SDA100X120SB FAQ
This 100mm bore model uses PT3/8 ports and 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. The theoretical maximum push force is 801 kgf at 1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. Additionally, it does not hold its load if air is lost; the piston will drift. For load holding, an external rod lock or pilot-operated check valve is required.
