The AirTAC AirTAC SDA63X5BH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 5mm 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 SDA63X5BH is a double-acting single-rod compact cylinder engineered for tight axial spaces. A riveted assembly unites the barrel, rear cover, piston, and rod, yielding an exceptionally short mounting footprint compared to conventional round-body units. Operating at 0.5 MPa, it generates 1558.6 N of push force and 1401.5 N of pull force. This specific SKU includes a male M18x1.5 piston rod end for secure mechanical coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
Because this model lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches. End-of-travel deceleration is handled strictly by fixed NBR bumpers rather than an adjustable air cushion. For the high kinetic energies generated by a 63 mm bore moving at up to 500 mm/s, incorporating an external shock absorber to slow the approach is strongly advised.

Applies a brief 1558.6 N clamping thrust at 0.5 MPa to hold thin metal plating sheets against an injection mold core, utilizing the 5 mm stroke to save vertical machine height.
Ejects finished aluminum turned parts from a CNC lathe chuck, where the FKM seals withstand oily coolant spray and the male M18x1.5 rod threads directly into the ejector mechanism.
Acts as a high-force stopper gate in a printed circuit board stacking line, rapidly extending 5 mm to block incoming boards while keeping the conveyor frame depth minimal.
Selecting this 63 mm bore provides a robust 1558.6 N push at 0.5 MPa, translating to a safe working load of roughly 935 N or a vertical lift capacity of about 79.4 kg with a 2:1 safety margin. If your application requires less force, the adjacent SDA50 delivers 981.7 N at 0.5 MPa; conversely, stepping up to the SDA80 provides 2513.3 N. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load. To maintain position, an external rod lock or pilot-operated check valve is required. When ordering, confirm the 5 mm stroke, PT1/4 port, male M18x1.5 rod thread, FKM seals, and the absence of a sensor magnet.
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, push is 2182.1 N and pull is 1962.2 N. The theoretical maximum push force is 318 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the speed range is 30-500 mm/s.
No, because this specific SKU lacks the -S magnet option, it cannot host AirTAC reed or electronic switches. You would need to specify the -S variant for position sensing. Additionally, end-stop deceleration relies on fixed NBR bumpers, not an adjustable air cushion, so external shock absorption is recommended for high-speed operations.
