About the Airtac SDA Ultra Thin Cylinder SDA100X75SB
The AirTAC SDA100X75SB is a double-acting, single-rod compact cylinder engineered to deliver substantial force 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 riveted body assembly significantly reduces overall length compared to conventional round-body units, saving valuable machine space.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It is also equipped with a male M26x1.5 threaded piston rod (-B) on a 32 mm shaft for robust load coupling. End-stops rely on a fixed NBR bumper to decelerate motion, which is not an adjustable air cushion, so external shock absorbers should be added for high-energy cycles.

Where the Airtac SDA Ultra Thin Cylinder SDA100X75SB Is Used
Injection Mold Ejection
Drives heavy ejector pins in plastic injection molding machinery where the short riveted body minimizes interference with the mold base while providing 3927 N of extend force.
Metal Stamping Alignment
Positions thick steel blanks under hydraulic presses, utilizing the 32 mm male-threaded rod for rigid attachment to heavy tooling and handling high lateral inertia during approach.
Palletizer Lift Stations
Actuates heavy lifting forks in automated end-of-line palletizing cells, where the built-in magnet enables reed or electronic switches to confirm load engagement at 75 mm of travel.
Is the Airtac SDA Ultra Thin Cylinder SDA100X75SB the Right Cylinder?
When sizing this unit, consider stepping down to the SDA80, which provides 2513.3 N of push force at 0.5 MPa, or if maximum thrust is required, this 100 mm bore stands as the largest standard option in the SDA family offering a theoretical maximum of 801 kgf at 1.0 MPa. Based on the 3927 N push figure at 0.5 MPa, the computed safe working load is approximately 2356 N (about 60% capacity), translating to a vertical lift capability of roughly 200.2 kg with a 2:1 safety margin.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed NBR bumper only decelerates near stroke end rather than locking the load. For vertical or suspended loads requiring fail-safe holding, an external rod lock or pilot-operated check valve is required. To order, confirm the 100 mm bore, 75 mm stroke, PT3/8 port, male M26x1.5 rod thread, and the integrated 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 SDA100X75SB FAQ
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, and 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 uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion; for high-speed cycles, add external shock absorbers. Furthermore, it does not lock the load on air loss, so an external rod lock or pilot-operated check valve is needed for vertical holding.
