The AirTAC AirTAC SDA50X160 Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm 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 SDA50X160 is a double-acting, single-rod compact cylinder engineered to deliver 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, and piston into a highly abbreviated unit, drastically reducing axial footprint compared to conventional round-body designs. This specific configuration features a 50 mm bore, a 20 mm piston rod, and a PT1/4 port.
Because the 160 mm stroke exceeds the 130 mm maximum standard stroke for this bore size, this unit is provided as a non-standard, made-to-order item. The bore is hard-anodized for longevity, while end-of-travel deceleration is handled strictly by fixed NBR bumpers rather than adjustable air cushions. This SKU omits the piston magnet, so it cannot support magnetic position sensing.

Drives a routing flap on a packaging conveyor to redirect 40 kg pallets, utilizing the 981.7 N push force to overcome sliding friction reliably.
Raises lightweight aluminum extrusion racks between processing tiers, safely handling a 50 kg vertical lift with a 2:1 safety margin at 0.5 MPa.
Extends 160 mm to fold heavy corrugated carton flaps prior to tape sealing, where the compact riveted body saves valuable machine footprint.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa, while moving up to the SDA63 provides 1558.6 N. Based on the 981.7 N output at 0.5 MPa, this 50 mm bore achieves a safe working load of roughly 589 N (60% capacity) and can vertically lift about 50 kg with a 2:1 safety margin. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates the stroke end and acts as neither a lock nor a brake. To hold a load securely without live pressure, incorporate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 50 mm bore, 160 mm non-standard stroke, PT1/4 port, female M10x1.5 rod thread, and no magnet.
Quick checklist
This 50 mm bore double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, increasing to 1374.4 N push and 1154.5 N pull at 0.7 MPa. The theoretical maximum push is 200 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
No. This specific SKU lacks the internal piston magnet, meaning it cannot accept AirTAC reed or electronic switches. Additionally, SDA series cylinders use fixed NBR bumpers to decelerate the stroke end rather than adjustable air cushions; for high-energy cycles, you should slow the approach or add external shock absorbers.
