Airtac SDA Ultra Thin Cylinder SDA100X90SB
The AirTAC Airtac SDA Ultra Thin Cylinder SDA100X90SB is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 90mm 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 SDA100X90SB
The AirTAC SDA100X90SB is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial envelope. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, this unit drastically reduces mounting depth compared to conventional round-body actuators. At its core, it generates a substantial 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, driven by a robust Ø32 mm piston rod and PT3/8 air ports.
This specific configuration includes the -S option, equipping the piston with a built-in magnet for direct compatibility with AirTAC reed or electronic switches housed in the body's peripheral grooves. The -B option specifies a male M26x1.5 threaded rod end for secure mechanical load coupling. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators must manage high kinetic energy externally or slow the approach speed appropriately.

Where the Airtac SDA Ultra Thin Cylinder SDA100X90SB Is Used
Stamping Press Ejection
Provides the heavy 3927 N extension force required to knock thick steel blanks from progressive stamping dies, utilizing the 90 mm stroke to clear the press bed safely.
Palletizer Lift Station
Raises heavy product layers during automated palletizing, where the male M26x1.5 rod end secures the lifting plate and the compact body saves critical vertical machine height.
Heavy Carton Sealing
Drives the high-pressure sealing heads on industrial corrugated box folders, relying on the fixed NBR bumper to absorb the repeated impact of rapid 30-500 mm/s cycling.
Is the Airtac SDA Ultra Thin Cylinder SDA100X90SB the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force margins carefully. Stepping down to the SDA80 yields 2513.3 N of push at 0.5 MPa, whereas this SDA100X90SB provides 3927 N at the same pressure, representing the maximum standard thrust in the SDA family. A computed safe working load is approximately 2356 N (about 60% of the 0.5 MPa figure), which translates to a vertical lift capacity of roughly 200.2 kg with a 2:1 safety margin. Ensure your ordering essentials match this exact profile: 100 mm bore, 90 mm stroke, PT3/8 port, male M26x1.5 rod thread, and a piston magnet. Remember that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. For suspended or vertical loads, integrate an external rod lock or a pilot-operated check valve.
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 SDA100X90SB FAQ
This double-acting cylinder 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 increases to 5497.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and functions 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 will drift. For load holding, an external rod lock or pilot-operated check valve is required.
