The AirTAC AirTAC SDA100X50BH 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 SDA100X50BH is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted assembly integrates the barrel, rear cover, and piston to deliver a substantial 3927 N push at 0.5 MPa, achieving high force output without the extended depth of traditional round-body units. This specific configuration includes a male M26x1.5 piston rod end and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
The 100 mm bore features a hard-anodized inner wall and a fixed NBR bumper at each end to decelerate the stroke. Because this bumper is not an adjustable air cushion, operators should slow the approach or utilize an external shock absorber for high-energy cycles. This SKU lacks a piston magnet, meaning it cannot support magnetic sensing; adding an -S variant enables reed or electronic switches in the body grooves.

Drives heavy stamping dies and holding fixtures where the 3927 N push force secures metal panels, utilizing the short riveted body to minimize press framework protrusion.
Actuates robust lifting gates on end-of-line packaging palletizers, moving loads safely up to 200.2 kg vertically with a 2:1 margin under 0.5 MPa supply.
Pushes thick-walled molded plastic components out of heavy tooling, relying on the FKM seals to withstand elevated ambient temperatures near the mold cavity.
When sizing this actuator, evaluate your force requirements carefully. Stepping down, the SDA80 provides a 2513.3 N push at 0.5 MPa, which may suffice for lighter loads while saving space. If maximum thrust is required, this 100 mm bore is the largest in the series, delivering a theoretical maximum of 801 kgf at 1.0 MPa. For safe operation, a computed working load is approximately 2356 N (60% of the 0.5 MPa rating), allowing a vertical lift of roughly 200.2 kg with a 2:1 safety margin.
Remember that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end rather than locking it. To maintain position, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 100 mm bore, 50 mm stroke, PT3/8 port, male M26x1.5 rod thread (-B), FKM seals (-H), and no magnet.
Quick checklist
This 100 mm bore double-acting cylinder generates a push of 3927 N and a pull of 3524.9 N at 0.5 MPa. At 0.7 MPa, the push increases to 5497.8 N and the pull to 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
No, the SDA100X50BH uses a fixed NBR bumper to decelerate the piston at the stroke ends, which is not a field-adjustable air cushion. Additionally, it is a standard actuator without a locking mechanism; if air is lost, the piston will drift. To hold a load securely, you must install an external rod lock or a pilot-operated check valve.
