About the Airtac SDA Ultra Thin Cylinder SDA100X25SBH
The AirTAC SDA100X25SBH is a double-acting, single-rod compact cylinder engineered for heavy-duty tasks within a minimal axial footprint. Utilizing a short riveted body assembly, it conserves machine mounting depth where standard round-body or profile units fail to fit. At 100 mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa. This specific configuration includes a male M26x1.5 piston rod thread, a built-in magnet for position sensing, and high-temperature fluororubber (FKM) seals.
The unit relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. For high-energy cycles, operators should slow the approach or install an external shock absorber. The hard-anodized bore and two-way piston seal ensure durability, while the integrated magnetic ring allows tracking via AirTAC reed or electronic switches.

Where the Airtac SDA Ultra Thin Cylinder SDA100X25SBH Is Used
Injection Mold Ejection
Drives heavy ejector pins in plastic injection molding machinery, utilizing the 3927 N push force to break large parts from the mold cavity.
Metal Stamping Feed
Acts as a robust short-stroke clamp in automated stamping lines, securing heavy gauge steel coils before the press descends.
Palletizer Lift Stop
Halts loaded pallets on high-throughput packaging conveyors, absorbing kinetic energy via the fixed NBR bumper at the end of travel.
Is the Airtac SDA Ultra Thin Cylinder SDA100X25SBH the Right Cylinder?
When sizing this 100 mm bore actuator, stepping down to the SDA80 yields 2513.3 N of push at 0.5 MPa, making the SDA100X25SBH the necessary choice when exceeding 2.5 kN of extension force. A computed safe working load is roughly 2356 N (about 60% of the 3927 N figure), allowing a vertical lift of approximately 200.2 kg with a 2:1 safety margin. If your mechanism must hold a load vertically during air loss or valve centering, note that the piston will drift; an external rod lock or pilot-operated check valve is required. Confirm your ordering essentials: 100 mm bore, 25 mm stroke, PT3/8 port, male M26x1.5 rod, FKM seals, and the S magnet option.
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 SDA100X25SBH FAQ
This 100 mm bore model uses a PT3/8 air port. It delivers 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum push of 801 kgf at 1.0 MPa.
No, a plain compact cylinder does not lock position upon air loss or valve centering; the piston drifts. The fixed NBR bumper only decelerates the stroke near the end cap and acts neither as a lock nor a brake. To maintain a suspended load, install an external rod lock or pilot-operated check valve.
