About the Airtac SDA Ultra Thin Cylinder SDA100X150B
The AirTAC SDA100X150B is a double-acting single-rod compact cylinder engineered for heavy-duty pneumatics within a minimal axial footprint. Its riveted assembly merges the barrel, rear cover, piston, and rod to save mounting depth where conventional round-body units fail to fit. At 100 mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, operating via PT3/8 ports.
This specific SKU features a male M26x1.5 threaded piston rod end for robust mechanical load coupling. Because the 150 mm stroke exceeds the 130 mm maximum standard length for this bore size, it is manufactured as a non-standard made-to-order item. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber.

Where the Airtac SDA Ultra Thin Cylinder SDA100X150B Is Used
Stamping Press Ejection
Provides robust 3927 N push force to eject heavy formed metal panels from stamping press dies, utilizing the male M26x1.5 rod end to securely thread into heavy tooling fixtures.
Palletizer Lift Station
Handles vertical lifting of 200.2 kg industrial pallet loads with a 2:1 safety margin, where the compact riveted body minimizes overhead machinery height requirements.
Injection Mold Separation
Delivers the high thrust necessary to break loose and separate large injection molding halves, relying on the fixed NBR bumper to absorb the shock of sudden mechanical stops.
Is the Airtac SDA Ultra Thin Cylinder SDA100X150B the Right Cylinder?
When sizing this actuator, evaluate your force margins carefully. Stepping down, the SDA80 provides 2513.3 N of push at 0.5 MPa, which is often insufficient if you require the full 3927 N capability of this 100 mm bore. Since this is the largest diameter in the series, there is no larger SDA option for higher thrust. Based on the 0.5 MPa output, the computed safe working load is approximately 2356 N (about 60 percent of capacity), translating to a vertical lift of roughly 200.2 kg with a 2:1 safety margin.
Confirm your ordering essentials: 100 mm bore, 150 mm non-standard stroke, PT3/8 port, male M26x1.5 rod thread (B option), and no sensor magnet. A plain compact actuator cannot hold a load if air pressure drops or the valve is centered, as the piston will drift and the fixed bumper only decelerates near the stroke end; incorporate an external rod lock or pilot-operated check valve for suspended loads.
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 SDA100X150B FAQ
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum push of 801 kgf at 1.0 MPa.
No, this specific SKU lacks the internal piston magnet, so it cannot accept AirTAC reed or electronic switches. You would need the -S option variant to utilize the magnetic sensor grooves machined around the body.
