Airtac SDA Ultra Thin Cylinder SDA50X5
The AirTAC Airtac SDA Ultra Thin Cylinder SDA50X5 is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 5mm 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.

About the Airtac SDA Ultra Thin Cylinder SDA50X5
The AirTAC SDA50X5 is a double-acting single-rod compact cylinder engineered for tight axial spaces, delivering a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. Its riveted assembly minimizes overall length compared to conventional round-body units, making it highly effective for machinery with restricted mounting depth. The hard-anodized 50 mm bore operates at speeds from 30-500 mm/s.
This specific SKU features a very short 5 mm stroke and lacks a piston magnet, meaning it cannot directly host AirTAC reed or electronic switches. End-of-travel deceleration is handled strictly by a fixed NBR bumper at each end rather than an adjustable air cushion. The 20 mm piston rod utilizes a female M10x1.5 thread, and pneumatic supply connects via PT1/4 ports.

Where the Airtac SDA Ultra Thin Cylinder SDA50X5 Is Used
Short-Stroke Stamping
Executes brief 5 mm embossing or marking actions on sheet metal presses where a 981.7 N extend force is sufficient but axial mounting room is severely restricted.
Carton Flap Folding
Provides a rapid, compact punch to fold packaging flaps on automated boxing lines, utilizing the 824.7 N retract force to reset quickly without occupying valuable frame depth.
Component Seating
Presses bearings or pins into housings on assembly fixtures, leveraging the 20 mm rod and fixed NBR bumpers to ensure parts bottom out consistently within a tiny 5 mm travel.
Is the Airtac SDA Ultra Thin Cylinder SDA50X5 the Right Cylinder?
When sizing this unit, evaluate your force margins carefully. Stepping down to an SDA40 reduces the 0.5 MPa push capacity to 628.3 N, while stepping up to an SDA63 increases it to 1558.6 N. For the SDA50X5, a safe working load is approximately 589 N (about 60% of the 981.7 N figure), allowing a vertical lift of roughly 50 kg with a 2:1 safety margin. To order, confirm the 50 mm bore, 5 mm stroke, PT1/4 port, and female M10x1.5 rod thread. Note that a plain SDA cylinder drifts when air pressure is lost or the valve is centered; the fixed NBR bumper only decelerates the stroke end and does not function as a lock. For suspended loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDA Ultra Thin Cylinder SDA50X5 FAQ
At 0.5 MPa, the push force is 981.7 N and the pull force is 824.7 N. At 0.7 MPa, the push force is 1374.4 N and the pull force is 1154.5 N. The theoretical maximum push force is 200 kgf at 1.0 MPa, which is the maximum operating pressure.
No, this specific SKU does not include a piston magnet, so it cannot host AirTAC reed or electronic switches. You would need the SDA50X5S variant for sensing capabilities. Additionally, end-stop deceleration relies on a fixed NBR bumper, not an adjustable air cushion.
