About the Airtac SDA Ultra Thin Cylinder SDA100X50
The AirTAC SDA100X50 is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. It delivers a substantial 3927 N of push force and 3524.9 N of pull force at 0.5 MPa. By utilizing a riveted assembly that joins the barrel, rear cover, and piston, this unit achieves a much shorter overall length than conventional round-body actuators, saving valuable machine mounting depth.
This 100mm bore model features a robust 32mm piston rod and PT3/8 air ports. The hard-anodized bore interior ensures long seal life, while end-of-stroke deceleration is handled by fixed NBR bumpers rather than adjustable cushions. This specific SKU does not include a piston magnet, meaning it cannot support AirTAC reed or electronic switches without upgrading to the -S variant.

Where the Airtac SDA Ultra Thin Cylinder SDA100X50 Is Used
Stamping Press Ejection
Provides the high 3927 N push force required to knock heavy stamped metal panels out of progressive die tooling within a tight press footprint.
Palletizer Lift Station
Lifts lowerator cartons in end-of-line packaging machinery, utilizing the 32mm rod to handle substantial vertical payloads without excessive axial overhang.
Injection Mold Separation
Breaks the vacuum seal on large plastic injection molds, using the 50mm stroke to safely initiate part ejection before the main robotic extractor enters.
Is the Airtac SDA Ultra Thin Cylinder SDA100X50 the Right Cylinder?
Selecting this 100mm bore actuator involves balancing your force requirements against spatial constraints. If your application needs less force, stepping down to the SDA80 provides 2513.3 N of push at 0.5 MPa; however, if the SDA100X50 is the upper limit of your design envelope, note that it is the largest bore in the SDA family. A practical computed insight for sizing: this model safely handles a working load of roughly 2356 N (about 60% of the 3927 N figure at 0.5 MPa) and can vertically lift approximately 200.2 kg with a 2:1 safety margin.
Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end and acts as neither a lock nor a brake. If your setup demands strict position holding, you must integrate an external rod lock or a pilot-operated check valve. To order, confirm your requirements for the 50mm stroke, PT3/8 ports, female M18x1.5 rod-end thread, and the absence of a sensor magnet.
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 SDA100X50 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3524.9 N. At 0.7 MPa, the push force is 5497.8 N. The theoretical maximum push force is 801 kgf at the 1.0 MPa operating pressure limit.
No, this model uses fixed NBR bumpers to decelerate at the stroke end and does not feature an adjustable air cushion. Additionally, this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches; you would need the -S variant for position sensing.
