The AirTAC AirTAC SDA63X40S Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 40mm 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 SDA63X40S 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 larger profile units cannot fit. The hard-anodized bore and two-way piston seal ensure durable, leak-free operation.
This specific configuration includes a built-in piston magnet (-S) for position detection via AirTAC reed or electronic switches mounted in the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be added for high-energy loads. The 63mm bore pairs a 20mm rod with PT1/4 ports and a female M10x1.5 rod-end thread.

Provides the 1558.6 N extension force needed to eject dense plastic parts from confined mold tooling, utilizing the short riveted body to fit within tight press platens.
Drives heavy cardboard flaps during automated case erecting, where the fixed NBR bumper safely absorbs the 40mm stroke impact without requiring external cushioning adjustments.
Raises and lowers light material handling gates, lifting up to 79.4 kg vertically with a 2:1 margin while the -S magnet triggers AirTAC electronic switches for precise height confirmation.
When sizing this actuator, compare its output against adjacent bores: stepping down to the SDA50 yields 981.7 N push at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N. For the SDA63X40S, the 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 your ordering essentials cover the 63mm bore, 40mm stroke, PT1/4 port, female M10x1.5 thread, and the required -S magnet.
Keep in mind that a standard compact cylinder will not hold a load if air pressure drops or the valve is centered; the piston drifts until the bumper makes contact. If your application demands position holding without live pressure, integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 63mm bore cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa. At 0.7 MPa, push increases to 2182.1 N and pull to 1962.2 N. The theoretical maximum push force is 318 kgf at 1.0 MPa, operating within a 0.15-1.0 MPa pressure range.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion; high-speed applications may need external shock absorbers. The included -S magnet works with AirTAC reed or electronic switches in the body grooves for position feedback.
