About the Airtac SDA Ultra Thin Cylinder SDA100X20SB
The AirTAC SDA100X20SB is a double-acting, single-rod compact cylinder engineered for heavy-duty tasks requiring substantial force in a minimal axial footprint. It delivers a robust 3927 N push and 3524.9 N pull at 0.5 MPa, achieving a theoretical maximum push of 801 kgf at 1.0 MPa. The riveted body assembly significantly reduces overall length compared to conventional round-body units, making it highly effective for machinery where mounting depth is restricted.
This specific configuration includes a built-in piston magnet (S) for position detection via AirTAC reed or electronic switches fitted into the body grooves, and a male M26x1.5 threaded piston rod (B) for secure load coupling. The 100 mm bore utilizes a PT3/8 air port and a 32 mm rod. End-of-stroke deceleration is handled by a fixed NBR bumper, which is not an adjustable air cushion, so external shock absorbers should be considered for high-energy impacts.

Where the Airtac SDA Ultra Thin Cylinder SDA100X20SB Is Used
Stamping Press Ejection
Provides the high-impact thrust needed to eject thick steel blanks from progressive stamping dies, utilizing the 5497.8 N push force available at 0.7 MPa.
Heavy Gauge Metal Bending
Acts as a compact press ram for forming heavy gauge brackets, where the short 20 mm stroke and male M26x1.5 rod securely drive the bending tooling.
Palletizer Lift Station
Handles heavy payload elevation in end-of-line packaging machinery, offering a space-saving riveted body that fits within tight vertical lift columns.
Is the Airtac SDA Ultra Thin Cylinder SDA100X20SB the Right Cylinder?
Selecting this 100 mm bore model provides massive output, but sizing appropriately is critical. If your application requires less force, stepping down to the SDA80 yields 2513.3 N push at 0.5 MPa; if you need maximum thrust, this SDA100 represents the top of the range. At 0.5 MPa, the computed safe working load is approximately 2356 N (about 60% of the push figure), translating to a vertical lift capacity of roughly 200.2 kg with a 2:1 safety margin. When ordering, confirm the 100 mm bore, 20 mm stroke, PT3/8 port, the S magnet option, and the B male rod thread. Note that a standard cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near stroke end rather than locking the load; utilize an external rod lock or pilot-operated check valve if position holding is mandatory.
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 SDA100X20SB FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3524.9 N. At 0.7 MPa, the push force is 5497.8 N. The theoretical maximum push force is 801 kgf at the 1.0 MPa operating pressure limit.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion; for high-speed cycling, add an external shock absorber. The included S magnet works with AirTAC reed or electronic switches for precise position detection.
