The AirTAC SDA63X90BH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 90mm 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 SDA63X90BH is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly abbreviated unit, drastically reducing axial mounting depth compared to conventional round-body designs. This specific configuration includes a male M18x1.5 piston rod end for robust mechanical coupling and utilizes a fluororubber (FKM) seal for heightened thermal and oil resistance.
Driven through PT1/4 ports, the 63 mm bore moves a 20 mm rod at speeds between 30 and 500 mm/s. The internal bore is hard-anodized to minimize friction, while end-stops rely on a fixed NBR bumper that decelerates the piston near stroke limits rather than providing an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot support magnetic reed or electronic switches.

Drives ejection pins on a 150-ton injection molding press where the FKM seals withstand elevated ambient heat and the 1558.6 N force clears finished plastic parts reliably.
Pushes heavy timber pallets off a high-speed packaging line, utilizing the male M18x1.5 thread to secure a robust wear plate against repeated side impacts.
Raises a 75 kg machining fixture on a vertical lift gate, operating safely within the 79.4 kg capacity limit while benefiting from the space-saving riveted body footprint.
When sizing this unit, evaluate your force margins carefully: stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, while moving up to the SDA80 provides 2513.3 N. If your mechanism must maintain vertical position during air loss or valve centering, the piston will drift; the fixed bumper only softens the end of travel and acts as neither a lock nor a brake. You must integrate an external rod lock or a pilot-operated check valve to secure the load.
Confirm your ordering parameters to match this exact SKU: 63 mm bore, 90 mm stroke, PT1/4 port thread, no sensor magnet, male M18x1.5 rod thread, and FKM seals. This 90 mm stroke sits well within the 130 mm standard maximum for this bore size.
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, the push is 2182.1 N and the pull is 1962.2 N. The theoretical maximum push is 318 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 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 accept AirTAC reed or electronic switches. To detect position, you would need the -S variant or external mechanical sensors. End-of-stroke impact is managed by a fixed NBR bumper that decelerates the piston; it is not an adjustable air cushion, so high-speed applications may require external shock absorbers.
