Airtac SDA Ultra Thin Cylinder SDA50X10
The AirTAC Airtac SDA Ultra Thin Cylinder SDA50X10 is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 10mm 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 SDA50X10
The AirTAC SDA50X10 is a double-acting single-rod compact cylinder engineered for tight axial spaces, delivering a robust 981.7 N push force at 0.5 MPa. Its riveted assembly significantly reduces overall length compared to conventional round-body units, making it highly effective for minimizing machine footprint. The hard-anodized bore and two-way piston seal ensure durable, leak-free operation.
This specific configuration features a 10 mm stroke and a 20 mm piston rod. End-stop deceleration relies strictly on a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorption. Note that this SKU lacks a piston magnet, so position sensing is not supported without the -S option.

Where the Airtac SDA Ultra Thin Cylinder SDA50X10 Is Used
Injection Mold Ejection
Provides short 10 mm ejection strokes inside cramped mold platens, utilizing the 981.7 N extend force to knock finished plastic parts safely out of the cavity.
Carton Flap Folding
Drives compact folding mechanisms on high-speed packaging lines where minimal axial depth is critical, using its 824.7 N retract force to tuck flaps prior to sealing.
Press Brake Gauging
Positions back-gauge stops on sheet metal equipment; the fixed NBR bumper accurately halts the 20 mm rod at stroke end without requiring complex cushion adjustments.
Is the Airtac SDA Ultra Thin Cylinder SDA50X10 the Right Cylinder?
When sizing this actuator, evaluate your force requirements bidirectionally: stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N. For the SDA50X10 itself, a safe working load is approximately 589 N (about 60% of its 981.7 N capacity), translating to a vertical lift capability of roughly 50 kg with a 2:1 safety margin. Confirm your ordering essentials: 50 mm bore, 10 mm stroke, PT1/4 port, female M10x1.5 rod thread, and no sensor magnet. Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only slows travel near the end of the stroke, so applications requiring load holding must incorporate 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 SDA50X10 FAQ
This double-acting 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. It operates between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. You must select the SDA50X10S variant to enable position sensing. Additionally, end-of-stroke deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.
