The AirTAC AirTAC SDA63X30SH 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 SDA63X30SH is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N of push force at 0.5 MPa. Its riveted body assembly integrates the barrel, rear cover, piston, and rod into a highly shortened axial footprint, conserving valuable machine space where a conventional round-body unit would be too deep. The bore is hard-anodized and utilizes a two-way piston seal for reliable operation.
This specific configuration includes the S option, equipping the piston with a built-in magnet for direct compatibility with AirTAC reed or electronic switches fitted into the body grooves. The H designation indicates a fluororubber (FKM) seal variant, providing enhanced resistance to higher temperatures and oil exposure. Deceleration at the stroke ends is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy cycling.

Provides the robust 1558.6 N extension force needed to eject dense plastic parts from mold cavities, with the FKM seals surviving ambient heat near the mold platen.
Raises heavy layer-forming platforms in end-of-line packaging machinery, where the short 30 mm stroke precisely indexes product tiers without wasting vertical space.
Actuates heavy clamping mechanisms on metal forming equipment, taking advantage of the 20 mm rod diameter to handle significant side-load resistance during tool engagement.
When sizing this 63 mm bore actuator, consider stepping down to the SDA50, which provides 981.7 N of push force at 0.5 MPa, or moving up to the SDA80, which yields 2513.3 N at the same pressure. For the SDA63X30SH, the computed safe working load is approximately 935 N (about 60% of the 1558.6 N figure), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. Ensure your ordering essentials cover the 63 mm bore, 30 mm stroke, PT1/4 port, female M10x1.5 rod thread, the S magnet, and the H FKM seal. Note that a standard compact cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the end of travel. To maintain position, an external rod lock or pilot-operated check valve is required.
Quick checklist
This double-acting cylinder generates 1558.6 N of push and 1401.5 N of 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 1.0 MPa. It operates on filtered air between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion; for high-speed cycling, you should add external shock absorbers. Furthermore, it does not inherently hold a load when air is lost or the valve is centered, as the bumper is not a locking brake, so an external rod lock or pilot-operated check valve is necessary for fail-safe holding.
