The AirTAC AirTAC SDA100X50SBH Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 50mm 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 SDA100X50SBH is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted assembly reduces overall length compared to conventional round-body units, delivering a substantial 3927 N push at 0.5 MPa. Equipped with a 32 mm piston rod, this model utilizes a PT3/8 port and operates at speeds between 30-500 mm/s.
This specific configuration includes an S option for a built-in piston magnet compatible with AirTAC reed or electronic switches, a B option providing a male M26x1.5 threaded rod end, and an H fluororubber (FKM) seal variant for enhanced thermal and oil resistance. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy cycles.

Drives heavy mold ejector pins in plastic injection machinery where the compact riveted body minimizes interference with the press platen.
Provides robust clamping force for holding sheet metal panels during stamping operations, utilizing the 3927 N push capacity at 0.5 MPa.
Lifts heavy product layers in end-of-line palletizing equipment, offering a vertical lift capacity of approximately 200.2 kg with a 2:1 margin.
When sizing this 100 mm bore actuator, stepping down to the SDA80 yields a 2513.3 N push at 0.5 MPa, while this SDA100X50SBH represents the maximum standard bore in the series with an 801 kgf theoretical maximum at 1.0 MPa. Computed insights indicate a safe working load around 2356 N (approximately 60% of the 0.5 MPa output) and a vertical lift capacity of roughly 200.2 kg using a 2:1 safety margin. Ensure your ordering essentials cover the 100 mm bore, 50 mm stroke, PT3/8 port, male M26x1.5 rod thread, FKM seals, and the sensor magnet.
Note that a standard compact cylinder does not hold its position if air pressure is lost or the directional valve is centered; the piston will drift. The fixed bumper only decelerates the stroke near the end limits and does not function as a locking brake. If your application requires static load holding, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 100 mm bore double-acting cylinder uses a PT3/8 port. It generates a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, the push increases to 5497.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion; for high-speed cycles, add an external shock absorber. Additionally, it does not hold its load on air loss or valve centering, so an external rod lock or pilot-operated check valve is required for position holding.
