The AirTAC AirTAC SDA63X65S Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 65mm 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 SDA63X65S is a double-acting single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its riveted assembly unites the barrel, rear cover, piston, and rod into a highly abbreviated package, saving valuable axial mounting depth where a conventional round-body unit would protrude too far into the machinery. The 63 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable pneumatic actuation.
This specific configuration includes the built-in piston magnet (-S), enabling position detection via an AirTAC reed or electronic switch seated in the body grooves. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or mount an external shock absorber for high-energy loads. The 20 mm piston rod terminates in a female M10x1.5 thread, and the unit operates efficiently between 30 and 500 mm/s.

Drives the ejection plate inside a plastic injection molding machine, utilizing the short riveted body to fit within tight mold voids while providing 1558.6 N of extend force to strip finished parts.
Actuates a heavy-duty diverting arm on a packaging conveyor line, using the 65 mm stroke to push loaded pallets onto a secondary track without consuming excessive longitudinal frame space.
Secures heavy cast iron blocks during CNC machining operations, relying on the 20 mm rod and 1401.5 N pull force to hold the workpiece firmly against the fixture datum.
When sizing this 63 mm bore actuator, compare its 1558.6 N push at 0.5 MPa against adjacent options: the SDA50 provides 981.7 N if your footprint or force requirement is smaller, while the SDA80 offers 2513.3 N for heavier demands. For this specific model, the computed safe working load is approximately 935 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. To finalize your order, confirm the 65 mm stroke, PT1/4 port, the -S magnet for sensing, and the female M10x1.5 rod thread. Note that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates near stroke end and acts as neither a lock nor a brake. To suspend a load safely without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, increasing to 2182.1 N push and 1962.2 N pull at 0.7 MPa. The theoretical maximum push force is 318 kgf at the 1.0 MPa operating pressure limit.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion; for high-speed cycling, add an external shock absorber. The built-in magnet (-S) works with an AirTAC reed or electronic switch in the body grooves for position feedback.
