Airtac SDA Ultra Thin Cylinder SDA50X45
The AirTAC SDA Ultra Thin Cylinder SDA50X45 is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 45mm 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 SDA50X45
The AirTAC SDA50X45 is a double-acting single-rod compact cylinder engineered to deliver a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. Its hard-anodized bore and two-way piston seal ensure reliable operation within the 30-500 mm/s speed range across a -20 to +70 C temperature span.
Featuring a short riveted body that integrates the barrel, rear cover, piston and rod, this unit drastically reduces axial mounting depth where a round-body unit would fail to fit. End-of-stroke energy is managed by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow high-speed approaches or add external shock absorbers to prevent impact wear. This specific SKU lacks a piston magnet, so position sensing is not supported without upgrading to the -S variant for reed or electronic switches.

Where the Airtac SDA Ultra Thin Cylinder SDA50X45 Is Used
Package Diverting Gate
Actuates a routing flap on a logistics sorting line, utilizing the 981.7 N extend force to reliably push 40 kg cartons onto secondary chutes without derailing the flow.
Pallet Flap Folding
Folds corrugated cardboard flaps on an automated packing station, where the 45 mm stroke and fixed NBR bumpers provide rapid, repeatable tucking without crushing the box seams.
Is the Airtac SDA Ultra Thin Cylinder SDA50X45 the Right Cylinder?
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA40 reduces the 0.5 MPa push capacity to 628.3 N, while stepping up to the SDA63 increases it to 1558.6 N.
Confirm your ordering essentials: this 50 mm bore with a 45 mm stroke uses a PT1/4 port, a 20 mm rod, and a female M10x1.5 rod-end thread. Note that a plain compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the piston near stroke end rather than locking it; utilize an external rod lock or pilot-operated check valve if your application demands strict load holding.
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 SDA50X45 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. The theoretical maximum push force is 200 kgf at the 1.0 MPa operating pressure limit.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches in the body grooves, you must select the -S option code variant. Additionally, the fixed NBR bumper only decelerates the piston near the stroke end and does not function as an adjustable air cushion.
