The AirTAC AirTAC SDA63X80BH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 80mm 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 SDA63X80BH 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 assembly merges the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth compared to conventional round-body units. This specific SKU includes a male M18x1.5 threaded piston rod end for robust mechanical coupling and an FKM (fluororubber) seal variant for enhanced thermal and oil resistance.
The 63 mm bore features a hard-anodized inner wall and a two-way piston seal operating at speeds of 30-500 mm/s. End-of-stroke deceleration is handled by a fixed NBR bumper at each end, which absorbs impact energy but is not a field-adjustable air cushion. Because this configuration lacks the -S magnet option, it cannot support magnetic position sensing without changing the internal piston assembly.

Drives ejection pins on a 150-ton injection molding press where the FKM seals withstand high ambient mold heat and the male M18x1.5 rod securely threads into the ejector plate.
Raises a 75 kg layer of packaged goods using the 1558.6 N extend force, fitting into a tight 80 mm stroke envelope while requiring an external check valve to prevent drifting if air pressure drops.
Secures heavy cast iron engine blocks during machining operations, relying on the 1401.5 N retract force to pull the clamp arm tight against the part profile.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N. The SDA63X80BH offers a safe working load of roughly 935 N (about 60% of its 1558.6 N output) and can vertically lift approximately 79.4 kg with a 2:1 safety margin. If your mechanism must maintain vertical position during air loss or valve centering, note that this standard cylinder will drift; an external rod lock or pilot-operated check valve is required to hold the load securely.
To order correctly, confirm this exact configuration: 63 mm bore, 80 mm stroke, PT1/4 port, male M18x1.5 rod thread (B), FKM seals (H), and no sensor magnet. The 80 mm stroke is well within the 130 mm maximum standard stroke for this bore size, making it a readily available production dimension.
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, push increases to 2182.1 N and pull to 1962.2 N. The theoretical maximum push is 318 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa and a temperature range of -20 to +70 C.
No, this model uses a fixed NBR bumper at each end to decelerate the stroke, which cannot be field-adjusted like an air cushion; for high kinetic energy loads, slow the approach speed or add an external shock absorber. Additionally, this specific SKU lacks the -S magnet, so it cannot interface with reed or electronic switches.
