The AirTAC SDA63X40SBH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 40mm 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 SDA63X40SBH is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N of push force at 0.5 MPa. Its riveted body design integrates the barrel, rear cover, piston, and rod into a highly unified structure, drastically reducing axial mounting depth where a conventional round-body unit would be too bulky. This space-saving footprint makes it ideal for machinery requiring high force in tight cell envelopes.
This specific configuration includes a built-in piston magnet (-S) for position sensing via AirTAC reed or electronic switches, a male M18x1.5 threaded piston rod (-B) for secure load coupling, and fluororubber (-H) seals for enhanced thermal and oil resistance. The unit relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Operating efficiently between 30-500 mm/s, it utilizes a PT1/4 port and a 20 mm rod diameter to handle rigorous cyclic demands.

Drives the ejector pins on a 150-ton injection molding press, utilizing the male M18x1.5 rod end for rigid coupling and the FKM seals to withstand ambient heat radiating from the mold tooling.
Pushes loaded 75 kg logistics pallets onto a secondary packaging line, where the 1558.6 N extend force at 0.5 MPa easily overcomes sliding friction without requiring a larger profile cylinder.
Raises and lowers a vertical safety guard on a CNC machining center, saving valuable axial floor space while the integrated magnet enables reed or electronic switches to confirm door closure.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, whereas stepping up to the SDA80 provides 2513.3 N. If your mechanism must maintain a vertical position during air loss or valve centering, note that the piston will drift; an external rod lock or pilot-operated check valve is required to hold the load securely. To order, confirm the 63 mm bore, 40 mm stroke, PT1/4 port, male M18x1.5 rod, magnetic piston, and FKM seal specifications.
Quick checklist
This double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, and 2182.1 N push and 1962.2 N pull at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, handles temperatures from -20 to +70 C, and runs at speeds between 30-500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits, which is not an adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber or slow the approach speed. Furthermore, the bumper is not a locking device; if air pressure is lost, the piston will drift, so an external rod lock or pilot-operated check valve is necessary to hold a suspended load.
