The AirTAC AirTAC SDA63X90B 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 SDA63X90B is a double-acting, single-rod compact cylinder engineered to deliver 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into an ultra-short unit, drastically reducing axial mounting depth compared to conventional round-body designs. The 63 mm bore features a hard-anodized inner wall and a two-way piston seal operating at speeds between 30 and 500 mm/s.
This specific SKU includes the B option, providing a male M18x1.5 threaded piston rod end for secure mechanical load coupling. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. Because this configuration lacks the S magnet option, it cannot host reed or electronic switches in the body grooves.

Drives short-stroke pressing arms in stamping presses, utilizing the 1558.6 N extend force to form lightweight vehicle body panels.
Pushes heavy timber pallets onto secondary packaging lines, where the 90 mm stroke and male M18x1.5 rod end ensure rigid load transfer.
Applies downward clamping pressure on corrugated beverage cases during the glue sealing process, benefiting from the compact body depth in tight machinery.
When sizing this actuator, evaluate your force margins carefully. If you step down to an SDA50, the output drops to 981.7 N at 0.5 MPa, whereas stepping up to an SDA80 increases it to 2513.3 N. For this 63 mm bore, a safe working load is approximately 935 N (about 60% of the 1558.6 N figure), yielding a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. To finalize your order, confirm the 90 mm stroke, PT1/4 port, and the male M18x1.5 rod thread. Note that a plain actuator drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates near the stroke end and does not function as a locking brake, so install an external rod lock or pilot-operated check valve if your application requires position holding.
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 force is 2182.1 N and the pull force is 1962.2 N. The theoretical maximum push force is 318 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, this specific SKU does not include the S option, meaning it lacks a piston magnet and cannot trigger reed or electronic switches. You would need the SDA63X90BS variant for sensor compatibility. Additionally, end-stroke deceleration is handled by a fixed NBR bumper, not an adjustable cushion.
