The AirTAC AirTAC SDA100X40BH 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 SDA100X40BH 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 configuration includes a male M26x1.5 piston rod thread for secure mechanical load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
Built around a robust 32 mm piston rod and hard-anodized 100 mm bore, 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 SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches; position sensing requires external methods or the -S variant.

Provides the high 3927 N extension force needed to kick heavy stamped metal panels out of a progressive die within a tight press enclosure.
Raises loaded pallets during packaging line transitions, where the FKM seals withstand elevated ambient temperatures from nearby heat-shrink tunnels.
Shifts heavy mold cores in plastic injection machinery, utilizing the male M26x1.5 rod thread for rigid coupling to the tooling block.
When sizing this 100 mm bore actuator, compare its 3927 N push at 0.5 MPa against the neighboring SDA80, which provides 2513.3 N at the same pressure. If your application requires even greater thrust, the SDA100 represents the upper limit of this compact series. Based on the 0.5 MPa figure, a safe working load is approximately 2356 N (about 60% of capacity), translating to a vertical lift capability of roughly 200.2 kg with a 2:1 safety margin.
To finalize your order, confirm the 100 mm bore, 40 mm stroke, PT3/8 port, and the -B male M26x1.5 rod end. Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only absorbs end-of-stroke impacts and acts as neither a lock nor a brake. For vertical loads that must be held without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 100 mm bore double-acting cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 5497.8 N. The theoretical maximum thrust is 801 kgf at the 1.0 MPa operating pressure limit.
No, this specific SKU lacks the -S piston magnet, so it cannot host reed or electronic switches in the body grooves. Additionally, end-of-stroke deceleration is handled strictly by a fixed NBR bumper, which is not an adjustable cushion; high-speed applications may require external shock absorbers.
