Airtac SDA Ultra Thin Cylinder SDA100X30B
The AirTAC Airtac SDA Ultra Thin Cylinder SDA100X30B is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 30mm 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 SDA100X30B
The AirTAC SDA100X30B is a double-acting single-rod compact cylinder engineered for high-force tasks within a minimal axial footprint. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, this unit achieves a remarkably short overall length compared to conventional round-body actuators. It provides a substantial 3927 N push and 3524.9 N pull at 0.5 MPa, driven through PT3/8 ports.
This specific configuration includes the -B option, meaning it features a male M26x1.5 threaded piston rod end for robust mechanical coupling to your load. The bore is hard-anodized and uses a two-way piston seal. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, which safely decelerates the stroke but requires an external shock absorber for high-energy cycles. Note that without the -S magnet option, this SKU cannot host magnetic switches.

Where the Airtac SDA Ultra Thin Cylinder SDA100X30B Is Used
Stamping Press Ejection
Provides the heavy push force required to eject thick metal blanks from a stamping press die, utilizing the 30mm stroke for rapid, short-range part removal.
Injection Mold Separation
Generates sufficient extending force to break loose large molded plastic components from core pins during automated demolding operations on an injection molding machine.
Palletizer Stop Gate
Acts as a heavy-duty stop gate in a high-speed palletizing line, securely halting fully loaded pallets via the male M26x1.5 rod thread before the stretch wrapping station.
Is the Airtac SDA Ultra Thin Cylinder SDA100X30B the Right Cylinder?
When sizing this actuator, consider stepping down to the SDA80, which yields 2513.3 N of push force at 0.5 MPa if your application requires less power and a smaller footprint. The SDA100X30B itself provides a safe working load of roughly 2356 N (about 60% of its 3927 N capacity at 0.5 MPa) and can vertically lift approximately 200.2 kg with a 2:1 safety margin. Ensure your ordering essentials match your requirements: 100mm bore, 30mm stroke, PT3/8 port, male M26x1.5 rod thread, and no sensor magnet.
Keep in mind that a standard double-acting cylinder does not 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 rod near the stroke end without acting as a mechanical lock. If your machinery must maintain a load under these conditions, 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 SDA100X30B FAQ
This 100mm bore double-acting cylinder generates 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 force is 801 kgf at the 1.0 MPa pressure limit.
No, this specific SKU lacks the -S magnet option, so it cannot accept reed or electronic switches. Additionally, it uses a fixed NBR bumper at each end to decelerate the stroke rather than an adjustable air cushion. For high-speed or high-energy loads, you should add an external shock absorber.
