About the Airtac SDA Ultra Thin Cylinder SDA100X25
The AirTAC SDA100X25 is a double-acting single-rod compact cylinder engineered to deliver a substantial 3927 N push at 0.5 MPa. Utilizing a short riveted body design, it significantly reduces axial mounting depth compared to traditional round-body units, making it highly effective for machinery where space is at a premium. The hard-anodized bore and two-way piston seal ensure reliable operation across the 30-500 mm/s speed range.
This specific configuration features a 32 mm piston rod, female M18x1.5 rod-end threads, and PT3/8 air ports. It relies on a fixed NBR bumper at each end to decelerate the stroke end rather than an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot support magnetic reed or electronic switches for position sensing.

Where the Airtac SDA Ultra Thin Cylinder SDA100X25 Is Used
Injection Molding Extraction
Handles robust part extraction from injection molding machines, utilizing the 3927 N push force to reliably eject heavy plastic components.
Press Tool Ejection
Integrates into metal stamping presses to actuate heavy-duty ejection pins, benefiting from the short riveted body to minimize machine footprint.
Is the Airtac SDA Ultra Thin Cylinder SDA100X25 the Right Cylinder?
When sizing this unit, evaluate your force requirements carefully. Stepping down, the SDA80 provides 2513.3 N of push at 0.5 MPa, which may suffice for lighter loads. Stepping up is not possible as 100 mm is the largest bore in the SDA family. Remember that a plain compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near stroke end and does not function as a lock; for suspended loads, install an external rod lock or pilot-operated check valve. To order, confirm the 100 mm bore, 25 mm stroke, PT3/8 port, female rod thread, and no 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 SDA100X25 FAQ
The SDA100X25 delivers a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, the push force is 5497.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the stroke end, which is not an adjustable air cushion or a locking brake. Additionally, this specific SKU lacks a piston magnet, so it cannot support magnetic reed or electronic switches; you would need the -S variant for position sensing.
