The AirTAC AirTAC SDA50X120 Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 120mm 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 SDA50X120 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 significantly reduces axial mounting depth compared to conventional round-body units, making it highly effective for tight machinery footprints. The hard-anodized bore and two-way piston seal ensure durable performance across the 30-500 mm/s speed range.
This 50 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 end rather than an adjustable air cushion. Because this specific SKU lacks the -S magnet option, it cannot support magnetic position sensing; adding an external shock absorber is advised for high-energy 120 mm stroke cycles.

Executes 120 mm sorting strokes on logistics conveyor lines, using its 981.7 N thrust to positively redirect heavy cartons into secondary routing lanes.
Folds corrugated cardboard flaps on automated packing stations, where the short riveted body minimizes machine width and the fixed NBR bumper absorbs the end impact.
Ejects formed sheet metal parts from stamping presses, leveraging the 20 mm rod and 50 kg vertical lift capacity to clear heavy blanks safely.
When sizing this unit, consider stepping down to the SDA40 which provides 628.3 N of push at 0.5 MPa, or moving up to the SDA63 which yields 1558.6 N at the same pressure. At 981.7 N, this 50 mm bore offers a safe working load of roughly 589 N (about 60% capacity) and can vertically lift approximately 50 kg with a 2:1 safety margin. To confirm your ordering essentials: specify the 50 mm bore, 120 mm stroke, PT1/4 port, female M10x1.5 rod thread, and note that no sensor magnet is included here. If your application must hold a load without live pressure, the piston will drift; you should integrate an external rod lock or pilot-operated check valve, as the fixed rubber bumper acts only as an end-stop and never as a braking device.
Quick checklist
This 50 mm bore 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 force is 200 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa and a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option code to enable position sensing. Additionally, the end caps use fixed NBR bumpers rather than adjustable cushions, so external shock absorbers are recommended for high-speed operations.
