The AirTAC AirTAC SDA63X5SB 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 SDA63X5SB is a double-acting single-rod compact cylinder engineered for high force in extremely tight axial spaces. Delivering a robust 1558.6 N push at 0.5 MPa, it features a minimal 5 mm stroke ideal for short clamping or ejection movements. The riveted body design drastically reduces overall mounting depth compared to conventional round-body units, ensuring your machinery maintains a small footprint without sacrificing power.
This specific configuration includes a built-in piston magnet (-S) for direct compatibility with AirTAC reed or electronic switches, fitting neatly into the body's sensor grooves. It is also equipped with a male-thread piston rod (-B) sized at M18x1.5 for secure mechanical load coupling. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be added for high-energy impacts.

Uses the 1558.6 N extend force to eject formed sheet metal parts from a stamping die within a 5 mm clearance zone.
Employs the short 5 mm stroke to rapidly fold minor carton flaps on a high-speed packaging line where axial depth is severely restricted.
Secures heavy automotive castings during machining operations, utilizing the male M18x1.5 rod end for rigid fixture mounting.
Selecting this 63 mm bore model provides substantial thrust, but sizing both ways ensures an optimal fit. Stepping down, the SDA50 offers 981.7 N push at 0.5 MPa, whereas stepping up to the SDA80 yields 2513.3 N at the same pressure. For this SDA63X5SB, 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.
When integrating this cylinder, remember that a standard double-acting unit drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near stroke end and does not act as a brake. For applications requiring suspended load holding, an external rod lock or pilot-operated check valve is necessary. Confirm your ordering essentials: 63 mm bore, 5 mm stroke, PT1/4 port, built-in magnet, and male M18x1.5 rod thread.
Quick checklist
This double-acting 63 mm bore 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. The theoretical maximum push force is 318 kgf at 1.0 MPa.
It relies on a fixed NBR bumper to decelerate the piston at stroke end, which is not an adjustable air cushion. Additionally, it does not hold its position if air is lost; the piston will drift. For load holding, you must use an external rod lock or pilot-operated check valve.
