The AirTAC SDA63X5S Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 5mm 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 SDA63X5S is a double-acting single-rod compact cylinder engineered for tight axial spaces, delivering a robust 1558.6 N push and 1401.5 N pull at 0.5 MPa. Its riveted body assembly significantly reduces overall mounting length compared to round-body units, making it highly effective for machinery with minimal footprint clearance. The 63 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable operation.
This specific configuration includes a 5 mm stroke and a built-in piston magnet (indicated by the S option) for use with AirTAC reed or electronic switches along the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorbers. The unit operates at 30-500 mm/s and uses a PT1/4 port paired with a 20 mm rod.

Provides high-force 1558.6 N clamping in tight press tooling footprints where a 5 mm stroke secures sheet metal blanks for punching operations.
Uses the built-in magnet and electronic switches to confirm ejection position, breaking small plastic parts free from mold cavities with precise 5 mm movements.
Delivers rapid 5 mm downward pressure to snap-fit or seal container lids, utilizing the 1401.5 N pull at 0.5 MPa to retract quickly for high-speed lines.
Selecting this model ensures a genuine AirTAC component with a 63 mm bore, 5 mm stroke, PT1/4 port, built-in magnet, and a female M10x1.5 rod thread. When sizing your application, stepping down to the SDA50 yields 981.7 N of push force at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift, as the fixed NBR bumper only decelerates the stroke end and does not act as a mechanical lock. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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, the push force is 2182.1 N and the pull force is 1962.2 N. The theoretical maximum push force is 318 kgf at the maximum operating pressure of 1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the piston. It is not an adjustable air cushion, so for high-speed or high-energy loads, you should add an external shock absorber or slow down the approach speed. The S option denotes a built-in magnet for reed or electronic switches, not a cushion.
