The AirTAC AirTAC SDA63X55BH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 55mm 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 SDA63X55BH is a double-acting, single-rod compact cylinder engineered with a 63 mm bore and 55 mm stroke. Its riveted assembly significantly reduces axial mounting depth compared to round-body units, providing a highly space-efficient footprint for mid-tier force applications. Delivering 1558.6 N of push force at 0.5 MPa, it integrates a hard-anodized bore and a two-way piston seal for reliable longevity.
This specific configuration includes an -H fluororubber (FKM) seal variant for enhanced thermal and oil resistance, alongside a -B male M18x1.5 piston rod thread for robust load coupling. Deceleration at stroke ends is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this SKU lacks a piston magnet, so position sensing is not supported without the -S option.

Drives ejector pins on mid-sized plastic injection molding machines, utilizing the FKM seals to withstand high ambient heat and oil mist near the clamp unit.
Pushes heavy corrugated cartons onto outbound pallets in end-of-line packaging systems, where the 1558.6 N force and 55 mm stroke clear products efficiently.
Positions and squares heavy-gauge steel blanks in progressive stamping presses before the hit, leveraging the male M18x1.5 rod for secure tooling attachment.
When sizing this actuator, evaluate your force requirements carefully. Stepping down, the SDA50 provides 981.7 N of push at 0.5 MPa, whereas stepping up to the SDA80 yields 2513.3 N. The SDA63X55BH strikes a middle ground, offering a safe working load of approximately 935 N (about 60% of its 1558.6 N capacity) and a vertical lift capability of roughly 79.4 kg with a 2:1 safety margin. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near the end of travel and does not function as a locking brake. If your application requires strict position holding, you must integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 63 mm bore, 55 mm stroke, PT1/4 port, male M18x1.5 rod thread, and FKM seals.
Quick checklist
This 63 mm bore double-acting cylinder provides a push force of 1558.6 N and a pull force of 1401.5 N at 0.5 MPa. At 0.7 MPa, the push increases to 2182.1 N and pull to 1962.2 N. The theoretical maximum push is 318 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No, this specific SKU lacks the -S piston magnet, meaning it cannot support AirTAC reed or electronic switches. You would need the -S variant for sensing capabilities. Additionally, end-of-stroke deceleration relies solely on a fixed NBR bumper; it is not an adjustable air cushion, so high-speed applications may require external shock absorbers.
