About the Airtac SDA Ultra Thin Cylinder SDA63X50
The AirTAC SDA63X50 is a double-acting single-rod compact cylinder engineered to deliver a push force of 1558.6 N and a pull force of 1401.5 N at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into an exceptionally short axial footprint, conserving machine space where a conventional round-body unit would be too long. The bore is hard-anodized and relies on a two-way piston seal for reliable operation across a 30-500 mm/s speed range.
This specific SKU lacks a piston magnet and therefore cannot host magnetic switches; adding the -S option enables reed or electronic switch integration via the body grooves. End-stop deceleration is handled strictly by a fixed NBR bumper, which is not an adjustable air cushion. With a 50 mm stroke and a PT1/4 port, this 63 mm bore model provides robust actuation for demanding industrial layouts.

Where the Airtac SDA Ultra Thin Cylinder SDA63X50 Is Used
Injection Mold Ejection
Drives ejection pins on a 150-ton injection molding press, utilizing the 1558.6 N push force to reliably strip finished plastic parts from the tool cavity.
Corrugated Box Flap Folding
Folds heavy corrugated cardboard flaps on an automated case erector, where the 1401.5 N pull force securely tucks the material against the main product flow.
Metal Stamping Feed Stop
Acts as a hard mechanical stop for coil steel feeding into a mechanical stamping press, taking advantage of the short 50 mm stroke to maintain a tight machine footprint.
Is the Airtac SDA Ultra Thin Cylinder SDA63X50 the Right Cylinder?
When sizing this unit, consider stepping down to the SDA50, which yields 981.7 N of push force at 0.5 MPa, or moving up to the SDA80 for 2513.3 N at the same pressure. Based on the 1558.6 N output at 0.5 MPa, a safe working load is approximately 935 N (about 60 percent of capacity), translating to a vertical lift capability of roughly 79.4 kg with a 2:1 safety margin. To finalize your order, confirm the 63 mm bore, 50 mm stroke, PT1/4 port, female rod-end thread (M10x1.5), and the absence of a magnet. Note that this cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered—the fixed bumper only decelerates the stroke end, so an external rod lock or pilot-operated check valve is required for position 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 SDA63X50 FAQ
This double-acting cylinder generates a push force of 1558.6 N and a pull force of 1401.5 N at 0.5 MPa. At 0.7 MPa, the push increases to 2182.1 N and the pull to 1962.2 N. The theoretical maximum push is 318 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa, and it operates in temperatures from -20 to +70 C.
This specific SKU does not include a piston magnet, so it cannot support magnetic switches; you would need the -S variant for reed or electronic switch sensing. Additionally, end-of-stroke deceleration is provided by a fixed NBR bumper, which is not an adjustable air cushion. For high kinetic energy loads, you should slow the approach speed or install an external shock absorber.
