About the Airtac SDA Ultra Thin Cylinder SDA100X80BH
The AirTAC SDA100X80BH is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted body assembly significantly reduces mounting depth compared to conventional round-body units, delivering a robust 3927 N push force at 0.5 MPa. This specific SKU includes an H option for fluororubber (FKM) seals, enhancing resistance to higher temperatures and oil exposure, and a B option providing a male M26x1.5 threaded piston rod end for secure mechanical load coupling.
The unit features a hard-anodized 100 mm bore and operates at speeds between 30-500 mm/s via PT3/8 ports. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs impact energy but is not a field-adjustable air cushion. Because this configuration lacks the S magnet option, it cannot support magnetic reed or electronic switches; position sensing requires external methods.

Where the Airtac SDA Ultra Thin Cylinder SDA100X80BH Is Used
Heavy Stamping Press Feed
Drives heavy metal sheet feeding mechanisms into a stamping press, utilizing the 3927 N push force to overcome mechanical friction in high-vibration automotive part production.
Palletizer Case Pusher
Pushes filled corrugated shipping cases onto accumulation pallets in end-of-line packaging systems, where the short riveted body conserves valuable conveyor footprint.
Injection Mold Ejection
Acts as a secondary ejection probe for thick-walled plastic injection molds, leveraging the male M26x1.5 rod thread to securely attach custom stripper tooling.
Is the Airtac SDA Ultra Thin Cylinder SDA100X80BH the Right Cylinder?
When sizing this actuator, evaluate your force margins carefully. Stepping down, the SDA80 provides 2513.3 N of push force at 0.5 MPa, making the SDA100X80BH the correct choice when your application exceeds that threshold and requires the full 3927 N. 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 capability of roughly 200.2 kg with a 2:1 safety margin. Ensure your ordering essentials match this exact configuration: 100 mm bore, 80 mm stroke, PT3/8 port, male M26x1.5 rod thread, and FKM seals.
Keep in mind that a standard double-acting cylinder does not inherently hold its position if air pressure is lost or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near its end limit rather than locking the load. If your machinery requires strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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 SDA100X80BH FAQ
This 100 mm bore double-acting cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa, increasing to 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push force is 801 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, handles a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
No. This specific SKU lacks the S magnet option, so it cannot accept AirTAC reed or electronic switches for position sensing. Additionally, it uses a fixed NBR bumper at each end to decelerate the stroke end, which is not an adjustable air cushion; for high-speed or high-energy cycles, you should slow the approach or add an external shock absorber.
