The AirTAC AirTAC SDA63X20SBH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 20mm 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 SDA63X20SBH 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 design significantly reduces axial mounting depth, offering a distinct footprint advantage in tight machinery spaces compared to conventional round-body units. This specific configuration includes a built-in piston magnet (-S) for position sensing, a male-threaded M18x1.5 piston rod (-B), and high-temperature fluororubber (FKM) seals (-H).
The unit features a hard-anodized 63 mm bore and relies on a fixed NBR bumper at each stroke end to absorb impact energy. Because this bumper is not a field-adjustable air cushion, operators should slow the approach or utilize an external shock absorber for high-speed operations. The body incorporates integrated grooves designed to accept AirTAC reed or electronic switches, enabling precise end-of-stroke detection when paired with the internal magnet.

Provides the 1558.6 N push force necessary to eject dense plastic parts from injection molding tools, where the compact riveted body minimizes interference with mold plates.
Handles vertical lifting of heavy product layers in end-of-line palletizing machinery, utilizing the 20 mm stroke for precise, short-travel tier separation.
Drives heavy-duty folding mechanisms on high-speed corrugated carton sealing lines, benefiting from FKM seals that resist thermal degradation in heated glue environments.
When sizing this actuator, evaluate your force requirements against its 1558.6 N push capacity at 0.5 MPa. If your application demands less energy, the smaller SDA50 bore provides 981.7 N of push force at the same pressure; conversely, stepping up to the SDA80 yields 2513.3 N for heavier loads. Based on the 0.5 MPa output, the safe working load is approximately 935 N (60% of capacity), translating to a vertical lift capability of about 79.4 kg with a 2:1 safety margin.
Keep in mind that a standard compact cylinder cannot maintain its position or hold a load if air pressure drops or the directional valve is centered—the piston will drift, and the fixed bumper only decelerates near the stroke end rather than acting as a mechanical lock. To secure a suspended load, you must integrate an external rod lock or a pilot-operated check valve. When ordering, verify the 63 mm bore, 20 mm stroke, PT1/4 port, male M18x1.5 rod thread, FKM seals, and the required magnetic sensor option.
Quick checklist
This 63 mm bore double-acting cylinder generates 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. At 0.7 MPa, the push increases to 2182.1 N. The theoretical maximum push is 318 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, has a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
The -B option designates a male-threaded M18x1.5 piston rod end, replacing the default female M10x1.5 thread, for direct mechanical coupling to your load. Instead of an adjustable air cushion, the cylinder uses a fixed NBR bumper at each end to decelerate the piston. For high kinetic energy loads, you should add an external shock absorber.
