The AirTAC SDA63X90SB 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 SDA63X90SB is a double-acting, single-rod compact cylinder engineered to deliver a robust 1558.6 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into an exceptionally short axial package, conserving valuable machine footprint where a conventional round-body unit would be too deep. The internal bore is hard-anodized, and the piston relies on a two-way seal for efficient actuation.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, plus a male-thread piston rod (-B) sized at M18x1.5 for secure mechanical load coupling. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent impact damage.

Drives the ejection plate inside a plastic injection molding machine, utilizing the 1558.6 N extend force to reliably strip finished parts from the tool cavity.
Actuates the side flap folding arms on a continuous carton packaging line, where the short riveted body minimizes axial intrusion into the conveyor framing.
Selecting this 63 mm bore over the SDA50 (981.7 N push @0.5 MPa) provides a significant strength upgrade, while stepping up to the SDA80 (2513.3 N push @0.5 MPa) offers even heavier capacity if your frame allows. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only slows the piston near stroke end and does not function as a locking brake, so install an external rod lock or pilot-operated check valve if the load must be held. To order, confirm the 90 mm stroke, PT1/4 port, S magnet, and male M18x1.5 rod thread.
Quick checklist
This 63 mm bore double-acting 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 and the pull to 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 speed range of 30-500 mm/s.
No, the SDA63X90SB uses a fixed NBR bumper at each end to decelerate the piston near the stroke extremes; it is not an adjustable air cushion. For high-speed or high-energy cycles, you should slow the approach speed or add an external shock absorber. Additionally, this SB variant includes a male M18x1.5 rod thread and a piston magnet for use with AirTAC reed or electronic switches.
