The AirTAC AirTAC SDA63X15BH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 15mm 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 SDA63X15BH is a double-acting single-rod compact cylinder engineered for tight axial spaces. A riveted assembly joining the barrel, rear cover, and piston yields a remarkably short footprint compared to conventional round bodies, delivering a robust 1558.6 N push at 0.5 MPa. This specific SKU includes an H designation, utilizing fluororubber (FKM) seals for enhanced thermal and oil resistance within the standard -20 to +70 C operating range.
Built with a 63 mm bore and a concise 15 mm stroke, this unit features a 20 mm piston rod with a male M18x1.5 thread end for direct load coupling. End-of-travel deceleration relies on fixed NBR bumpers rather than adjustable cushions, meaning high-speed approaches may require external shock absorption. Because this configuration lacks the S magnet option, it cannot host magnetic position sensors.

Short 15 mm stroke precisely knocks finished plastic parts out of tight mold cavities where machine frame depth is strictly limited.
Generates 1558.6 N of extend force to secure heavy steel plates during CNC milling operations, utilizing the FKM seals to resist coolant exposure.
Raises lightweight machining fixtures 15 mm against gravity; pair with a pilot-operated check valve to prevent drifting when the air supply is cut.
When sizing this 63 mm bore actuator, consider stepping down to the SDA50, which provides 981.7 N of push force at 0.5 MPa, or moving up to the SDA80, which yields 2513.3 N at the same pressure. For the 1558.6 N output at 0.5 MPa, a safe working load is approximately 935 N (about 60 percent of capacity), translating to a vertical lift capability of roughly 79.4 kg with a 2:1 safety margin. To finalize your order, confirm the 63 mm bore, 15 mm stroke, PT1/4 port, male M18x1.5 rod thread, and the FKM seal option. Note that a standard cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates near stroke end and does not function as a locking brake. If your application demands position holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 63 mm bore cylinder exerts a push force of 1558.6 N and a pull force of 1401.5 N at 0.5 MPa. At 0.7 MPa, the push increases to 2182.1 N. The theoretical maximum push is 318 kgf at the 1.0 MPa operating pressure limit.
No, it uses fixed NBR bumpers at the stroke ends for deceleration rather than field-adjustable air cushions. Additionally, this specific SKU lacks the S magnet option, so it cannot support reed or electronic switches. It does feature a male M18x1.5 piston rod thread for load attachment.
