The AirTAC AirTAC SDA100X45BH Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 45mm 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 SDA100X45BH 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 substantial 3927 N push force at 0.5 MPa. This specific SKU includes a male M26x1.5 piston rod end for robust mechanical coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
Designed with a 100 mm bore and a 45 mm stroke, the unit operates at speeds between 30-500 mm/s via PT3/8 ports. Instead of an adjustable air cushion, the piston relies on a fixed NBR bumper at each end to decelerate the stroke. Because this configuration omits the -S magnet, it cannot support magnetic position sensing; the -S variant is required for reed or electronic switches.

Provides the high-impact force needed to knock heavy sheet metal blanks from progressive stamping dies, utilizing the 45 mm stroke for rapid part clearance.
Applies concentrated thrust to flatten thick steel plates in metal fabrication lines, where the male M26x1.5 rod securely threads into heavy tooling fixtures.
Drives the vertical elevation platform in automated end-of-line palletizing cells, handling loads near the 200 kg vertical lift threshold with FKM seals resisting harsh plant environments.
When sizing this actuator, consider stepping down to the SDA80, which provides 2513.3 N of push force at 0.5 MPa, or remain at the 100 mm bore for maximum thrust. Based on the 3927 N output at 0.5 MPa, the computed safe working load is approximately 2356 N (about 60% capacity), translating to a vertical lift capability of roughly 200.2 kg with a 2:1 safety margin. Ensure your ordering essentials match this exact configuration: 100 mm bore, 45 mm stroke, PT3/8 port, male M26x1.5 rod thread (-B), and FKM seals (-H) without a sensor magnet.
Keep in mind 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, and the fixed NBR bumper only decelerates the load near the stroke end rather than acting as a mechanical lock. If your application demands strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 100 mm bore cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa, increasing to 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push force is 801 kgf at the 1.0 MPa operating pressure limit.
No, this specific SKU lacks the internal piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option to enable sensing, and note that the fixed NBR bumpers are not adjustable air cushions.
