The AirTAC AirTAC SDA100X40SBH Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 40mm 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 SDA100X40SBH is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted body assembly significantly reduces mounting depth compared to conventional round-body units, delivering a robust 3927 N push force at 0.5 MPa. This specific configuration includes a male M26x1.5 piston rod end, a built-in magnet for position sensing, and high-temperature fluororubber (FKM) seals.
The 100 mm bore features a hard-anodized inner wall and a 32 mm piston rod, operating at speeds from 30-500 mm/s. Instead of an adjustable air cushion, the piston strikes a fixed NBR bumper at each end to decelerate the stroke. Because this rubber buffer is not a locking device, an external shock absorber should be added for high-energy cycles.

Drives heavy metal blanks into progressive stamping presses, utilizing the 5497.8 N extend force at 0.7 MPa to push dense steel sheets reliably into the tooling dies.
Separates and positions empty wooden pallets on high-speed packaging lines, where the compact riveted body saves valuable machine length while managing heavy pallet mass.
Provides secondary ejection of thick molded plastic parts from heavy injection machinery, relying on the 32 mm rod and male M26x1.5 thread to securely attach heavy lifting tooling.
Selecting this 100 mm bore model provides a theoretical maximum push of 801 kgf at 1.0 MPa, with a safe working load around 2356 N (roughly 60% of the 3927 N figure at 0.5 MPa) and a vertical lift capacity of approximately 200.2 kg using a 2:1 safety margin. If your application requires less force, the neighboring SDA80 offers 2513.3 N push at 0.5 MPa; as the largest standard size, stepping up beyond 100 mm requires a different body style. When ordering, confirm the 40 mm stroke, PT3/8 port, male M26x1.5 rod thread, the S magnet option, and the H FKM seal variant. Remember that a standard cylinder drifts when air pressure is lost or the valve is centered, so integrate a pilot-operated check valve or external rod lock if you need to suspend a load safely.
Quick checklist
This 100 mm bore double-acting cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push 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 of 30-500 mm/s.
No, the S suffix indicates a built-in piston magnet that allows you to mount AirTAC magnetic switches in the body grooves. You can use either reed or electronic solid-state switches for position detection. Additionally, the H designation specifies fluororubber (FKM) seals for enhanced thermal and oil resistance.
