The AirTAC SDA100X55 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 SDA100X55 is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Delivering a substantial 3927 N push at 0.5 MPa, it relies on a hard-anodized bore and a two-way piston seal for longevity. Its short riveted body integrates the barrel, rear cover, piston, and rod to drastically reduce mounting depth where a conventional round-body actuator would not fit.
This 100 mm bore unit features a robust 32 mm piston rod and PT3/8 air ports. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers are recommended for high-energy approaches. Without an S suffix, this specific SKU lacks a piston magnet and therefore cannot host reed or electronic switches.

Thread: PT standard. Related SDA-family variants: SSA (single-acting push), STA (single-acting pull), SDAD (double rod), SDAJ (adjustable stroke), SDAT (duplex), SDAW (duplex-end).
Provides the heavy 3927 N push force required to knock thick steel blanks from stamping press dies, utilizing the short body to fit within tight press sub-plates.
Acts as a rugged back-gauge or holding clamp in plate rolling machinery, where the 32 mm rod resists deflection during heavy industrial bending tasks.
Selecting this model involves balancing your force requirements against spatial constraints. If 3927 N push at 0.5 MPa exceeds your needs, stepping down to the SDA80 provides 2513.3 N while saving valuable envelope space. Conversely, this 100 mm bore represents the maximum standard capacity in the SDA family, offering a theoretical maximum output of 801 kgf at 1.0 MPa.
When ordering, verify the 55 mm stroke, PT3/8 porting, and female M18x1.5 rod-end thread. Note that a plain double-acting actuator will drift and cannot hold a load if air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and acts as neither a lock nor a brake. For suspended loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
This 100 mm bore double-acting cylinder 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, because this specific SKU lacks the S suffix, it has no internal piston magnet and cannot accept reed or electronic switches. You would need to specify the SDA100X55S variant for sensor integration. Additionally, end stopping relies on a fixed NBR bumper, not an adjustable air cushion.
