The AirTAC AirTAC SDA63X160 Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 160mm 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 SDA63X160 is a double-acting single-rod compact cylinder engineered to deliver a substantial 1558.6 N push and 1401.5 N pull at 0.5 MPa. Because the 160 mm stroke exceeds the 130 mm standard limit for this 63 mm bore, this specific unit is manufactured as a non-standard, made-to-order configuration. The riveted body assembly significantly reduces axial mounting depth compared to conventional round-body cylinders, making it highly effective for conserving machine footprint in tight spaces.
This 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 end, rather than an adjustable air cushion. This SKU is supplied without a piston magnet, meaning it cannot support magnetic position sensing out of the box. For high kinetic energy loads, an external shock absorber or a slowed approach speed is recommended.

Actuates heavy-duty diverting arms on packaging conveyors where the 1558.6 N push force easily overcomes pallet friction and the 160 mm stroke clears the transfer lane.
Deploys mechanical safety stops for multi-level material elevators, utilizing the 20 mm rod to arrest descending platforms weighing up to 79.4 kg.
Drives secondary ejection plungers in injection molding machines, saving axial depth while providing the robust 1401.5 N pull force needed to free dense plastic parts.
When sizing your actuator, evaluate the adjacent bores to ensure optimal performance. Stepping down, the SDA50 provides 981.7 N of push at 0.5 MPa, while stepping up to the SDA80 yields 2513.3 N. The SDA63X160 offers a safe working load of roughly 935 N (about 60% of its 1558.6 N capacity) and can vertically lift approximately 79.4 kg with a 2:1 safety margin.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure is lost or the directional valve is centered; the piston will drift. To maintain a vertical load safely, you must integrate an external rod lock or a pilot-operated check valve. To order, confirm your requirements for the 63 mm bore, 160 mm non-standard stroke, PT1/4 port, female M10x1.5 rod thread, and the absence of a sensor magnet.
Quick checklist
This 63 mm bore cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, increasing to 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, with an operating pressure range of 0.15-1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the stroke end and does not act as a lock or brake. For vertical load holding, you must install an external rod lock or a pilot-operated check valve.
