The AirTAC AirTAC SDA63X110BH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 110mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA63X110BH is a double-acting single-rod compact cylinder engineered to deliver 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. Its riveted body design significantly reduces axial mounting depth compared to round-body alternatives, saving valuable machine footprint in tight assemblies. This specific configuration includes a male M18x1.5 piston rod end for robust load coupling and an FKM (fluororubber) seal variant for enhanced thermal and oil resistance.
This model features a 110 mm stroke within a 63 mm bore, utilizing a PT1/4 port and a 20 mm rod diameter. It relies on a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot support magnetic position sensing without modifying the build.

Drives the ejection plate in plastic injection molding machines where the FKM seals withstand high ambient heat and the 1558.6 N push force clears finished parts from the mold cavity.
Applies downward clamping pressure on veneer pressing lines, utilizing the 110 mm stroke to accommodate varying panel thicknesses while keeping the press frame axially compact.
Actuates a routing gate on high-throughput packaging conveyors to deflect loaded pallets, relying on the male M18x1.5 thread for a secure linkage to the diverter arm.
When sizing this actuator, consider stepping down to the SDA50, which provides 981.7 N of push at 0.5 MPa, or stepping up to the SDA80, which yields 2513.3 N at the same pressure. For this 63 mm bore, the theoretical safe working load is approximately 935 N (about 60% of the 1558.6 N figure), allowing a vertical lift of roughly 79.4 kg with a 2:1 safety margin. Ensure you specify the 110 mm stroke, PT1/4 port, male M18x1.5 rod thread, and FKM seals when ordering.
A standard SDA cylinder does not hold its position or load if air pressure is lost or the valve is centered; the piston will drift, and the fixed rubber bumper only decelerates the stroke near the end without acting as a lock. If your application requires a held load without live pressure, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
At 0.5 MPa, the push force is 1558.6 N and the pull force is 1401.5 N. At 0.7 MPa, the push force is 2182.1 N and the pull force is 1962.2 N. The theoretical maximum push force is 318 kgf at the maximum operating pressure of 1.0 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits, which is not an adjustable air cushion. For high-speed or high-energy cycles, add an external shock absorber. Additionally, it does not hold a load on air loss; the piston drifts, so an external rod lock or pilot-operated check valve is required for position holding.
