The AirTAC AirTAC SDA63X30B Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 30mm 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 SDA63X30B is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N of push force at 0.5 MPa. By utilizing a riveted assembly that permanently joins the barrel, rear cover, piston, and rod, this design drastically reduces axial mounting depth compared to conventional round-body units. It operates at speeds between 30 and 500 mm/s, handling a safe working load of approximately 935 N, which translates to a vertical lift capacity of about 79.4 kg with a 2:1 safety margin.
This specific SKU features a male M18x1.5 piston rod thread for robust load coupling, paired with a 20 mm rod diameter and PT1/4 air ports. The bore is hard-anodized for longevity, while stroke termination relies on a fixed NBR bumper at each end rather than an adjustable air cushion. Because this configuration lacks the -S magnet option, it cannot directly host magnetic position sensors; achieving end-position detection would require the -S variant equipped for reed or electronic switches.

Provides the 1558.6 N extension force needed to push plastic parts out of tight mold cavities where the short riveted body minimizes press footprint.
Drives the folding and sealing flaps on automated packaging lines, utilizing the 30 mm stroke and fixed NBR bumpers to handle rapid cycling at up to 500 mm/s.
Actuates a short-stroke pusher to index raw material into the collet, leveraging the male M18x1.5 thread for a secure mechanical interface on the feed mechanism.
Selecting this 63 mm bore provides a middle-ground solution between the smaller SDA50, which yields 981.7 N of push at 0.5 MPa, and the larger SDA80, which generates 2513.3 N. If your application approaches the upper velocity limits and carries high kinetic energy, consider slowing the approach or adding an external shock absorber, as the fixed rubber bumper only decelerates the stroke end and cannot be field-tuned. When ordering, confirm the 30 mm stroke, PT1/4 porting, and the male M18x1.5 rod thread. Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; maintaining a suspended load requires 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, 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 adjustable air cushion is available; the unit uses a fixed NBR bumper at each end to decelerate the stroke. Additionally, this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S variant.
