The AirTAC AirTAC SDA100X55S Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 55mm 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.
The AirTAC SDA100X55S is a double-acting single-rod compact cylinder engineered for heavy-duty positioning within a minimal axial footprint. Utilizing a short riveted body assembly, it conserves valuable machine mounting depth where standard round-body units would fail to fit. At 100mm bore, it generates a substantial 3927 N push force at 0.5 MPa, supported by a rigid 32mm piston rod.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. Deceleration at stroke extremes relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycling. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.

Drives heavy gauge metal blanks into progressive stamping dies, utilizing the 5497.8 N extend force at 0.7 MPa to overcome material resistance and ensure precise placement.
Elevates loaded pallets within compact conveyor transfer zones, where the short riveted body length prevents interference with adjacent guard structures.
Applies downward clamping pressure to secure industrial drum lids, relying on the 32mm rod to resist deflection during high-force actuation.
Selecting this 100mm bore provides a theoretical maximum push of 801 kgf at 1.0 MPa, translating to a safe working load around 2356 N (roughly 60% of the 3927 N output at 0.5 MPa) or a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA80 yields 2513.3 N at 0.5 MPa; as the largest standard size, there is no larger SDA option. Keep in mind that a plain compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near the end of travel and does not function as a locking brake. To hold a load securely without live pressure, an external rod lock or pilot-operated check valve is required. When ordering, confirm the 55mm stroke, PT3/8 porting, female M18x1.5 rod thread, and the required magnetic sensor option.
Quick checklist
This 100mm bore model features PT3/8 ports and 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 is 801 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the directional valve is centered. The fixed NBR bumper only decelerates the piston near the stroke ends and does not act as a brake. An external rod lock or pilot-operated check valve is required for secure load holding.
