The AirTAC AirTAC SDA63X45B 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 SDA63X45B 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 merges the barrel, rear cover, piston, and rod into a highly shortened axial footprint, conserving valuable machine depth where conventional round bodies cannot fit.
This specific configuration features a male M18x1.5 threaded piston rod for robust mechanical coupling to your load. The bore is hard-anodized for longevity, while fixed NBR bumpers absorb end-of-stroke impacts. Note this SKU lacks a piston magnet, so position sensing is not supported without the -S option.

Drives ejection pins on a 150-ton injection molding press, utilizing the 45 mm stroke to safely clear the tooling cavity under high force.
Pushes heavy timber pallets onto a secondary packaging line, where the short riveted body prevents interference in tight transfer zones.
Folds large corrugated carton flaps prior to case sealing, relying on the male M18x1.5 rod end to securely hold a custom folding arm.
When sizing this actuator, compare its 1558.6 N extend force against adjacent bores: the SDA50 offers 981.7 N, while the SDA80 provides 2513.3 N at 0.5 MPa. For this 63 mm bore, a 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.
Remember that a standard compact cylinder drifts when air pressure is lost or the valve centers, as the fixed bumper only decelerates the stroke end rather than locking the piston. To suspend a load safely, integrate an external rod lock or pilot-operated check valve. To order, confirm the 63 mm bore, 45 mm stroke, PT1/4 port, and the male M18x1.5 rod thread.
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 0.15-1.0 MPa, with a speed of 30-500 mm/s.
No, it uses fixed NBR bumpers at each end to decelerate the stroke, which are not field-adjustable; for high kinetic energy, add an external shock absorber. Additionally, this SKU lacks the -S magnet, so it cannot accept AirTAC reed or electronic switches.
