The AirTAC AirTAC SDA100X55SB 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 SDA100X55SB is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Utilizing a riveted body assembly, it conserves machine mounting depth where conventional round-body units cannot fit. At 100 mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, with a theoretical maximum output of 801 kgf at 1.0 MPa.
This specific configuration includes a built-in piston magnet (-S) for use with AirTAC reed or electronic switches, and a male-thread piston rod (-B) sized at M26x1.5 for secure mechanical load coupling. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycles. The unit operates at 30-500 mm/s, features a hard-anodized 100 mm bore, and uses a PT3/8 air port.

Drives heavy metal blanks into a forming die where the 3927 N push force at 0.5 MPa easily overcomes material resistance and tooling friction.
Raises loaded pallets vertically, safely handling the 200.2 kg lift capacity within a 55 mm stroke while minimizing vertical machine height.
Ejects dense plastic components from molding machinery, utilizing the male M26x1.5 rod end for rigid attachment to the ejection plate.
Selecting this 100 mm bore model provides a safe working load of roughly 2356 N (about 60% of the 3927 N push force at 0.5 MPa), which translates to 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 of push at 0.5 MPa; as the largest available SDA bore, there is no larger standard option in this series. When ordering, confirm the 55 mm stroke, PT3/8 port, male M26x1.5 rod thread, and the integrated sensor magnet. Remember that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered—the piston will drift, as the fixed bumper only decelerates near stroke end and acts as neither a lock nor a brake. For suspended loads, an external rod lock or pilot-operated check valve is required.
Quick checklist
This double-acting 100 mm bore cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push with 4934.8 N pull at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles a proof pressure of 1.5 MPa, and runs at speeds from 30-500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits, which is not an adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber. Additionally, it does not hold its load if air is lost; the piston will drift, so an external rod lock or pilot-operated check valve is needed for position holding.
