The AirTAC AirTAC SDA63X45H Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 45mm 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 SDA63X45H is a double-acting single-rod compact cylinder engineered for tight axial footprints. Its riveted assembly significantly reduces overall length compared to conventional round-body units, yielding a robust 1558.6 N push force at 0.5 MPa. This specific SKU features an H-designation fluororubber (FKM) seal, elevating its resistance to higher ambient heat and oil-laden environments.
Equipped with a 20 mm piston rod and PT1/4 ports, it operates at speeds between 30-500 mm/s. The internal end-stop relies on a fixed NBR bumper rather than an adjustable cushion, effectively decelerating the stroke end without requiring field tuning. Since this configuration omits the S magnet code, it cannot host magnetic sensing hardware.

Drives ejection pins in plastic injection molding machines where the FKM seals withstand residual heat and the compact body fits within tight mold platens.
Actuates diverter gates on high-speed packaging lines, utilizing the 1558.6 N thrust to push heavy corrugated pallets into position.
Positions raw sheet metal blanks into stamping presses, taking advantage of the short 45 mm stroke to maintain a minimal machine footprint.
When sizing this 63 mm bore unit, consider stepping down to the SDA50 if your layout requires less force, as that model provides 981.7 N of push at 0.5 MPa. Conversely, if your mechanism demands greater thrust, the larger SDA80 generates 2513.3 N at the same 0.5 MPa pressure. Based on the 1558.6 N output, the computed safe working load is approximately 935 N, translating to a vertical lift capacity of about 79.4 kg with a 2:1 safety margin.
To finalize your order, verify the 45 mm stroke, PT1/4 porting, and the female M10x1.5 rod-end thread. Note that a standard actuator drifts when air pressure drops or the valve centers; the bumper only slows travel near the end of the stroke. If your mechanism must freeze a load mid-cycle without live pressure, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder delivers 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. The theoretical maximum push is 318 kgf at the 1.0 MPa operating pressure limit.
No, this specific SKU lacks the internal piston magnet, so it cannot host reed or electronic switches. You must select the SDA63X45HS variant to enable magnetic sensing. Additionally, end-of-travel deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.
