Airtac SDA Ultra Thin Cylinder SDA100X80
The AirTAC Airtac SDA Ultra Thin Cylinder SDA100X80 is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 80mm stroke, PT3/8 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 SDA100X80
The AirTAC SDA100X80 is a double-acting, single-rod compact cylinder engineered to deliver substantial thrust within a minimal axial footprint. It provides 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, extending to 5497.8 N push at 0.7 MPa. The hard-anodized 100 mm bore operates at speeds between 30-500 mm/s, utilizing a two-way piston seal for reliable performance.
This model features a 32 mm piston rod and PT3/8 air ports. Its short riveted body significantly reduces mounting depth compared to conventional round-body units, making it ideal for heavy-duty machinery where space is restricted. End-stopping is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorbers. This specific SKU lacks a piston magnet, so position sensing is not supported without the -S option.

Where the Airtac SDA Ultra Thin Cylinder SDA100X80 Is Used
Injection Mold Platen Ejection
Drives heavy ejector pins on a 200-ton injection molding platen, using the 3927 N push force to break plastic parts free from deep cavities within a tight machine envelope.
Heavy Gauge Steel Pressing
Performs final alignment and pressing of thick structural steel plates in an automotive chassis weld fixture, capitalizing on the 5497.8 N extend force at 0.7 MPa.
Palletizer Lift Station
Actuates a heavy mechanical lift platform in an end-of-line palletizer, lifting 200 kg payloads vertically while fitting into the narrow column depth of the conveyor frame.
Is the Airtac SDA Ultra Thin Cylinder SDA100X80 the Right Cylinder?
Selecting this 100 mm bore unit provides a maximum theoretical thrust of 801 kgf at 1.0 MPa, with a safe working load around 2356 N (approximately 60% of the 0.5 MPa figure) and a vertical lift capacity of roughly 200.2 kg at a 2:1 margin. If your application requires less force, the neighboring SDA80 offers 2513.3 N of push at 0.5 MPa; as the largest standard size, there is no larger SDA bore. When ordering, confirm the 80 mm stroke, PT3/8 port, female M18x1.5 rod thread, and the absence of a sensor magnet.
Because this is a double-acting cylinder, it will not hold a load if air pressure drops or the valve is centered—the piston will drift, and the fixed NBR bumper only decelerates near the stroke end rather than locking the rod. For vertical or suspended loads that must remain in place during a pneumatic failure, you must integrate an external rod lock or a pilot-operated check valve into your system.
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 SDA100X80 FAQ
The SDA100X80 generates 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push at 0.7 MPa. The theoretical maximum push is 801 kgf at the maximum operating pressure of 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need the SDA100X80S variant for position sensing. Additionally, end-stop deceleration relies on a fixed NBR bumper, not an adjustable air cushion.
