The AirTAC AirTAC SDA63X150BH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 150mm 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 SDA63X150BH is a double-acting, single-rod compact cylinder engineered to deliver a robust 1558.6 N push force at 0.5 MPa. Its short, riveted body assembly significantly reduces axial mounting depth, offering a distinct footprint advantage in tight machine layouts compared to conventional round-body units. This specific configuration includes a 150 mm stroke, which exceeds the 130 mm standard maximum for this bore, making it a non-standard, made-to-order item.
This model is equipped with a male M18x1.5 piston rod thread for secure load coupling and features an FKM fluororubber seal for enhanced thermal and oil resistance. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches. Stopping is managed by a fixed NBR bumper at each end rather than an adjustable air cushion, so high-energy cycles may require external shock absorption.

Pushes heavy stretch-wrap rolls onto packaging mandrels using its 1558.6 N extend force, where the FKM seals withstand warm production environments.
Actuates a heavy sorting gate on a parcel conveyor, utilizing the 150 mm stroke to fully clear the belt path for high-speed routing.
Drives a secondary ejection arm for plastic parts, taking advantage of the male M18x1.5 rod end for rigid mounting and the compact body to fit tight mold platens.
When sizing this actuator, consider stepping down to the SDA50, which provides 981.7 N of push at 0.5 MPa, or moving up to the SDA80, which yields 2513.3 N. For the SDA63X150BH itself, the computed safe working load is approximately 935 N (about 60% of the 1558.6 N output), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. Confirm your ordering essentials: 63 mm bore, 150 mm non-standard stroke, PT1/4 port, male M18x1.5 rod, and FKM seals.
Keep in mind that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed NBR bumper only decelerates the stroke near its end. If your application requires a locked load without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 63 mm bore double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, and 2182.1 N push at 0.7 MPa. The theoretical maximum push force is 318 kgf at the maximum operating pressure of 1.0 MPa.
No, this specific SKU does not include the -S piston magnet, so it cannot host AirTAC reed or electronic switches. You would need to specify the -S option to enable sensor grooves around the body for position detection.
