The AirTAC AirTAC SDA63X15B Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 15mm 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 SDA63X15B is a double-acting single-rod compact cylinder engineered to deliver a robust 1558.6 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth, providing a distinct footprint advantage in tight machinery layouts. The 63 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable pneumatic performance.
This specific SKU includes a male M18x1.5 piston rod thread for secure mechanical coupling to your load. Because it lacks the -S option, it has no piston magnet and cannot host position sensing. End-stop deceleration relies strictly on a fixed NBR bumper, which is not an adjustable air cushion; for high kinetic energy applications, consider an external shock absorber.

Drives short-stroke ejector pins on a 63 mm bore injection molding press, utilizing the 1558.6 N extend force to break plastic parts free from the tool cavity.
Deploys a 15 mm stroke to fold corrugated cardboard flaps on high-speed packaging lines, where the male M18x1.5 rod end securely threads into the folding armature.
Positions the back-gauge stop on a sheet metal press brake, relying on the compact riveted body to minimize protrusion into the operator work zone.
When sizing this actuator, evaluate your force requirements bidirectionally. Stepping down, the SDA50 offers 981.7 N of push at 0.5 MPa; stepping up, the SDA80 provides 2513.3 N. For the SDA63X15B, the theoretical safe working load is approximately 935 N (60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. Ensure you specify the 63 mm bore, 15 mm stroke, PT1/4 port, and male M18x1.5 rod thread when ordering.
Keep in mind that a standard compact pneumatic actuator cannot hold a load if air pressure drops or the control valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near its end without acting as a mechanical lock. If your application demands strict position holding, integrate an external rod lock or a pilot-operated check valve.
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 is 2182.1 N and pull is 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 speed of 30-500 mm/s.
No, this specific SKU does not include the -S option, meaning it lacks a piston magnet and cannot be used with AirTAC reed or electronic switches. You would need the SDA63X15BS variant to utilize the sensor grooves around the body.
