The AirTAC AirTAC SDA63X45SB Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 45mm 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 SDA63X45SB 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 into a highly shortened unit, drastically reducing axial mounting depth compared to conventional round-body designs. Driven by filtered air over a 30-500 mm/s speed range, it integrates a hard-anodized bore and a two-way piston seal for extended operational life.
This specific configuration includes a built-in piston magnet (-S) for triggering AirTAC reed or electronic switches along the body grooves, plus a male M18x1.5 threaded piston rod (-B) for robust load coupling. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. Operating between 0.15 and 1.0 MPa, the unit handles a theoretical maximum push of 318 kgf at 1.0 MPa.

Secures heavy cast iron engine blocks onto machining centers, utilizing the 1558.6 N extend force to maintain rigid positioning against high spindle torque.
Actuates routing flaps on automated packaging lines, where the shortened riveted body fits within tight 90-degree transfer module clearances.
Ejects stamped metal brackets from progressive dies, using the 1401.5 N retract force at 0.5 MPa to positively strip parts from punch tooling.
Selecting this 63 mm bore provides a safe working load of roughly 935 N (about 60% of the 1558.6 N push at 0.5 MPa), translating to a vertical lift capacity of approximately 79.4 kg with a 2:1 safety margin. If your application requires less force, the smaller SDA50 generates 981.7 N of push at 0.5 MPa; conversely, stepping up to the SDA80 yields 2513.3 N for heavier demands. When ordering, confirm the 45 mm stroke, PT1/4 port, male M18x1.5 rod end, and the integrated sensor magnet. Keep in mind that a standard compact cylinder drifts if air pressure drops or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load—implement an external rod lock or pilot-operated check valve if position holding is critical.
Quick checklist
At 0.5 MPa, this double-acting cylinder outputs 1558.6 N of push force and 1401.5 N of pull force. When supplied with 0.7 MPa, the push increases to 2182.1 N and the pull to 1962.2 N. The theoretical maximum push capacity is 318 kgf at the 1.0 MPa operating limit.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber or slow down the approach speed. Additionally, the -B option specifies a male M18x1.5 piston rod rather than the standard female thread.
