About the Airtac SDA Ultra Thin Cylinder SDA100X120
The AirTAC SDA100X120 is a double-acting single-rod compact cylinder engineered for heavy-duty pneumatic automation. It delivers a substantial 3927 N push force at 0.5 MPa, utilizing a robust Ø32 mm piston rod and PT3/8 air ports to handle high-cycle actuation tasks efficiently.
Its short riveted body significantly reduces axial mounting depth compared to traditional round-body units, conserving valuable machine footprint. The bore is hard-anodized for longevity, while a fixed NBR bumper at each end absorbs end-stop impact. This specific SKU lacks a piston magnet, meaning it cannot support magnetic position sensing without upgrading to the -S variant.

Where the Airtac SDA Ultra Thin Cylinder SDA100X120 Is Used
Injection Mold Ejection
Provides the robust 3927 N push force required to eject dense plastic parts from large injection molding machines, utilizing the 120 mm stroke to clear the mold bed entirely.
Press Brake Actuation
Drives heavy-duty forming blades in metalworking press brakes where a short axial footprint is critical, and the 801 kgf maximum output ensures consistent bending pressure.
Heavy Pallet Lifting
Lifts loaded pallets in automated packaging lines, offering a 200.2 kg vertical lift capacity with a 2:1 safety margin while fitting into tight conveyor elevation mechanisms.
Is the Airtac SDA Ultra Thin Cylinder SDA100X120 the Right Cylinder?
When sizing this model, evaluate your force requirements carefully. Stepping down, the SDA80 provides 2513.3 N push at 0.5 MPa, which may suffice for lighter loads. Stepping up is not possible as 100 mm is the largest bore in the SDA series, so for forces beyond 801 kgf at 1.0 MPa, a larger ISO profile cylinder would be required. This 100x120 configuration yields a safe working load of roughly 2356 N (about 60% of the 0.5 MPa figure) and a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin.
Confirm your ordering essentials: 100 mm bore, 120 mm stroke, PT3/8 port, female M18x1.5 rod thread, and no magnet. Note that a plain SDA cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift. For suspended or vertical loads, integrate an external rod lock or pilot-operated check valve. The fixed NBR bumper decelerates the stroke end but is not an adjustable cushion or a braking device.
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 SDA100X120 FAQ
The SDA100X120 generates 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, it yields 5497.8 N push and 4934.8 N pull. The theoretical maximum push force is 801 kgf at 1.0 MPa.
No. It uses a fixed NBR bumper to decelerate at stroke ends, which is not a field-adjustable air cushion. Additionally, this SKU lacks a piston magnet, so it cannot use reed or electronic switches; you must specify the -S option for sensing.
