The AirTAC 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.
Elevates lowerator arms in end-of-line palletizing machinery where the short riveted body minimizes vertical space requirements while lifting 200 kg loads with a safe margin.
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. Factoring a 2:1 safety margin yields a safe working load around 2356 N, translating to a vertical lift capacity of roughly 200.2 kg. 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.
