Airtac SDA Ultra Thin Cylinder SDA50X15
The AirTAC SDA Ultra Thin Cylinder SDA50X15 is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 15mm 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 SDA50X15
The AirTAC SDA50X15 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 joins the hard-anodized barrel, rear cover, and piston into an ultra-short unit, saving valuable axial mounting depth where a conventional round-body actuator would not fit.
This specific SKU features a 50 mm bore, a 15 mm stroke, and a PT1/4 port. It uses a fixed NBR bumper at each end to decelerate the stroke end rather than an adjustable air cushion. Because this base configuration lacks the -S magnet option, it cannot host reed or electronic switches.

Where the Airtac SDA Ultra Thin Cylinder SDA50X15 Is Used
Injection Mould Ejection
Provides a short 15 mm kick to eject plastic parts from injection moulding tools, saving axial depth inside the tight mould platen envelope.
Carton Flap Folding
Delivers 981.7 N of push at 0.5 MPa to tuck heavy cardboard flaps on packaging lines prior to case sealing.
Press Brake Gauging
Positions sheet metal backgauges on press brakes where the compact riveted body minimizes interference with the bending bed.
Is the Airtac SDA Ultra Thin Cylinder SDA50X15 the Right Cylinder?
When sizing this unit, verify if the 981.7 N push at 0.5 MPa meets your requirement. Stepping down to the SDA40 yields 628.3 N, while stepping up to the SDA63 provides 1558.6 N.
Note that a plain SDA body does not hold its load if air pressure drops or the valve is centred; the piston will drift, and the fixed bumper only decelerates near the stroke end rather than locking it. For secure holding, an external rod lock or pilot-operated check valve is required. Confirm your ordering essentials: 50 mm bore, 15 mm stroke, PT1/4 port, no magnet, and a female M10x1.5 rod-end thread.
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 SDA50X15 FAQ
The SDA50X15 generates 981.7 N push and 824.7 N pull at 0.5 MPa, and 1374.4 N push at 0.7 MPa. The theoretical maximum push is 200 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No. It relies on a fixed NBR bumper at each end to decelerate the stroke end, which is not an adjustable air cushion. Additionally, this specific SKU lacks the -S magnet, so it cannot support reed or electronic switches.
