The AirTAC SDA100X55BH 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 SDA100X55BH is a double-acting single-rod compact cylinder engineered for heavy-duty pneumatics within confined axial footprints. Utilizing a riveted body assembly, it achieves a remarkably short overall length compared to conventional round-body units, saving valuable machine mounting depth. At 100 mm bore, it generates 3927 N of push force at 0.5 MPa, supported by a robust 32 mm piston rod and PT3/8 air ports.
This specific SKU includes the -B option, providing a male M26x1.5 threaded rod end for secure direct load coupling, and the -H fluororubber (FKM) seal variant for enhanced thermal and oil resistance. Deceleration at stroke ends relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers are recommended for high-energy impacts. Because this configuration lacks the -S magnet, it cannot host reed or electronic switches.

Drives heavy blanking and forming holders in automotive panel stamping, utilizing the 3927 N push force to secure sheet metal during high-tonnage press cycles.
Extracts molded plastic components from high-temperature injection presses, leveraging the FKM seal option to withstand residual heat and synthetic lubricants.
When sizing this actuator, compare its 3927 N push at 0.5 MPa against the adjacent SDA80, which yields 2513.3 N, to determine if a smaller bore suffices. If your application demands the maximum theoretical output, this 100 mm bore achieves an 801 kgf limit at 1.0 MPa. Ensure your ordering essentials match this exact configuration: 100 mm bore, 55 mm stroke, PT3/8 ports, male M26x1.5 rod thread, and FKM seals. Note that a standard compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near the stroke end and does not function as a locking brake. For suspended loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
The SDA100X55BH delivers a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, the push force is 5497.8 N. The theoretical maximum push force is 801 kgf at the maximum operating pressure of 1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches; you would need the -S variant for position sensing.
