The AirTAC SDA Ultra Thin Cylinder SDA63X40 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 SDA63X40 is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. By utilizing a short riveted body that permanently joins the barrel, rear cover, piston and rod, this unit achieves an exceptionally small axial footprint. This space-saving architecture is ideal for machinery where a traditional round-body or profile cylinder would simply demand too much mounting depth.
This specific 63 mm bore model features a 20 mm piston rod and PT1/4 air ports. It relies on a fixed NBR bumper at each end to decelerate the stroke, meaning there is no field-adjustable air cushion to tune. Because this SKU lacks the -S magnet option, it cannot host AirTAC reed or electronic switches; position sensing requires the -S variant instead.

Provides the 1558.6 N push at 0.5 MPa required to snap heavy corrugated carton flaps into position on high-speed packaging lines.
Uses its 40 mm stroke and 20 mm rod to knock stamped metal parts out of a press die, benefiting from the short riveted body to fit tight tooling envelopes.
When sizing this actuator, stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N at the same pressure. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near stroke end rather than locking the load; an external rod lock or pilot-operated check valve is required for strict position holding. To order, confirm the 63 mm bore, 40 mm stroke, PT1/4 port, female rod-end thread (M10x1.5), and the absence of a sensor magnet.
Quick checklist
The SDA63X40 generates 1558.6 N push and 1401.5 N pull at 0.5 MPa. At 0.7 MPa, it yields 2182.1 N push and 1962.2 N pull. The theoretical maximum push is 318 kgf at 1.0 MPa, which is the maximum operating pressure.
No. This model uses a fixed NBR bumper at each end to decelerate the stroke end; it is not an adjustable air cushion. Additionally, this specific SKU lacks the -S magnet, so it cannot accept AirTAC reed or electronic switches.
