About the Airtac SDA Ultra Thin Cylinder SDA100X90S
The AirTAC SDA100X90S is a double-acting, single-rod compact cylinder engineered to deliver substantial thrust within a minimal axial footprint. It generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks. The unit features a hard-anodized bore and a two-way piston seal to ensure operational longevity.
This model incorporates a built-in piston magnet (-S) compatible with AirTAC reed or electronic switches, fitting neatly into the body sensor grooves for precise end-position detection. A fixed NBR bumper at each end absorbs end-stop impact; because this is not an adjustable air cushion, operators should slow the approach or utilize external shock absorbers for high-energy loads. The 32 mm rod and PT3/8 porting are set by the 100 mm bore, ensuring robust fluid delivery for its 90 mm stroke.

Where the Airtac SDA Ultra Thin Cylinder SDA100X90S Is Used
Injection Mold Ejection
Provides robust 3927 N push force to eject dense plastic parts from injection molding machinery, utilizing the compact riveted body to fit tight mold platen areas.
Heavy Press Staging
Positions thick metal blanks under hydraulic presses, where the 32 mm rod withstands side-load risks and the 90 mm stroke feeds material accurately into the die.
Pallet Lifter Actuation
Drives vertical lifting pins in automated pallet handling systems, lifting roughly 200 kg loads with a 2:1 safety margin while the magnetic sensor tracks position.
Is the Airtac SDA Ultra Thin Cylinder SDA100X90S the Right Cylinder?
Selecting this 100 mm bore provides a safe working load of roughly 2356 N (about 60% of the 3927 N push force at 0.5 MPa), translating to a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA80 yields 2513.3 N at 0.5 MPa; as the largest standard size, there is no larger SDA bore option. Remember that a plain compact cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates near the stroke end, so an external rod lock or pilot-operated check valve is necessary to hold a load securely.
When requesting a quote, confirm the essentials: 100 mm bore, 90 mm stroke, PT3/8 port, female M18x1.5 rod-end thread (or male M26x1.5 if specified), and the -S magnet option for sensor integration.
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 SDA100X90S FAQ
This double-acting cylinder 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 force is 801 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, it does not function as a lock or brake; if air is lost, the piston drifts. For load holding, you must install an external rod lock or a pilot-operated check valve.
