The AirTAC AirTAC SDA63X35BH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 35mm 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 SDA63X35BH is a double-acting, single-rod compact cylinder engineered for tight axial footprints. Its riveted body assembly minimizes overall length compared to traditional round-body units, delivering a robust 1558.6 N push force at 0.5 MPa. This specific SKU includes a male M18x1.5 piston rod end for secure mechanical load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
Designed with a 63 mm bore and a 35 mm stroke, the unit operates at speeds between 30-500 mm/s via PT1/4 ports. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Because this configuration omits the -S magnet option, it cannot support magnetic position sensing without altering the build.

Drives ejection pins in plastic injection molding machines where high 1558.6 N force and FKM seals withstand elevated ambient heat and lubricant exposure.
Folds corrugated carton flaps on high-speed packaging lines, utilizing the short 35 mm stroke and male M18x1.5 rod to securely drive mechanical folding arms.
Positions heavy sheet metal blanks in stamping presses, taking advantage of the 63 mm bore's robust push capacity within a shallow machine profile.
When sizing this actuator, evaluate your force margins 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. For the SDA63X35BH, a safe working load is approximately 935 N (about 60% of the 0.5 MPa output), translating to a vertical lift capacity near 79.4 kg with a 2:1 safety factor. Confirm your ordering essentials: 63 mm bore, 35 mm stroke, PT1/4 port, male M18x1.5 rod thread, and FKM seals.
Remember that a standard compact cylinder will not hold a load if air pressure drops or the valve centers. The piston will drift, and the fixed NBR bumper only slows travel near the stroke limits rather than locking it. If your application demands strict position holding, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 63 mm bore double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, increasing to 2182.1 N push and 1962.2 N pull at 0.7 MPa. The theoretical maximum push is 318 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a proof pressure of 1.5 MPa and a speed range of 30-500 mm/s.
No, this specific SKU lacks the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need the -S variant for position sensing. Additionally, end stopping relies on a fixed NBR bumper, not an adjustable air cushion, so external shock absorbers are advised for high-energy cycles.
