The AirTAC AirTAC SDA63X50BH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 50mm 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 SDA63X50BH is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its riveted body assembly significantly reduces axial mounting depth compared to traditional round-body units, providing a highly space-efficient footprint for machinery requiring robust mid-range actuation. This specific SKU includes a male M18x1.5 piston rod end for secure mechanical load coupling and utilizes a fluororubber (FKM) seal for enhanced thermal and oil resistance.
Instead of an adjustable air cushion, the end caps house fixed NBR bumpers that decelerate the piston near stroke termination. The bore is hard-anodized to minimize wear, and the unit operates at speeds between 30-500 mm/s. Because this configuration lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches; position sensing must be handled externally.

Provides the 1558.6 N push force required to eject dense plastic components from injection molding tools, with the male M18x1.5 rod ensuring rigid attachment to the ejector plate.
Handles vertical lifting of 79.4 kg payload tiers in end-of-line packaging machinery, where the compact riveted body minimizes vertical space requirements.
Secures heavy cast iron engine blocks during machining operations, leveraging FKM seals to withstand exposure to synthetic cutting fluids and high operating temperatures.
When sizing this 63 mm bore actuator, evaluate your force margins carefully. Stepping down, the SDA50 provides 981.7 N of push at 0.5 MPa, whereas stepping up to the SDA80 yields 2513.3 N. Based on the 1558.6 N output at 0.5 MPa, a safe working load is approximately 935 N (around 60 percent capacity), translating to a vertical lift capability of roughly 79.4 kg with a 2:1 safety margin. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates at the end of travel and acts as neither a lock nor a brake; holding a suspended load requires an external rod lock or pilot-operated check valve. Confirm your ordering essentials: 63 mm bore, 50 mm stroke, PT1/4 port, male M18x1.5 rod thread, and FKM seals.
Quick checklist
This double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 2182.1 N. 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, meaning it cannot host AirTAC reed or electronic switches in the body grooves. You would need to specify the -S option for internal position sensing, or utilize external mechanical sensors.
