The AirTAC AirTAC SDA63X55S Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 55mm 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 SDA63X55S 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 joins the barrel, rear cover, piston, and rod into a highly abbreviated unit, drastically reducing axial mounting depth compared to conventional round-body actuators. This space-saving footprint is ideal for machinery where tight clearances are a primary design constraint.
This specific configuration includes a built-in piston magnet (-S) for direct compatibility with AirTAC reed or electronic switches, which seat neatly into the grooves around the body. The 63 mm bore dictates a PT1/4 port and a 20 mm rod. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorbers to prevent impact damage.

Provides the 1558.6 N push stroke required to eject dense plastic parts from tight mold cavities where the 55 mm travel and abbreviated body length prevent interference with the press platen.
Actuates a heavy routing flap on a high-speed packaging line, using the built-in magnet to confirm gate position via electronic sensors while managing rapid 55 mm shifts.
Functions as a robust physical stop pin in an automated warehouse lift, raising 20 mm into a pallet void to arrest loads up to 79.4 kg before the lower conveyor engages.
When sizing this actuator, evaluate your force requirements against adjacent bores. Stepping down, the SDA50 provides 981.7 N of push at 0.5 MPa; stepping up, the SDA80 yields 2513.3 N at the same pressure. For the SDA63X55S, the 1558.6 N output at 0.5 MPa translates to a safe working load of roughly 935 N (operating at a 2:1 margin) or a vertical lift capacity of about 79.4 kg. Confirm your ordering essentials: 63 mm bore, 55 mm stroke, PT1/4 port, female rod-end thread (M10x1.5), and the -S magnet option.
Remember that a standard compact cylinder does not hold its position if air pressure is lost or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the load near the stroke end—it is not a locking brake. If your application demands fail-safe load holding, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder generates 1558.6 N of push force and 1401.5 N of pull force. 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 the speed range is 30-500 mm/s.
No. It uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, it does not hold its load if air is lost or the valve is centered; the piston will drift. For position holding, an external rod lock or pilot-operated check valve is required.
