About the Airtac SAI100 Standard Air Cylinder SAI100X150
The AirTAC SAI100X150 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 150mm stroke. It delivers a robust 3927N push force and 3681N pull force at 0.5MPa, making it well-suited for heavy-duty positioning tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This configuration ships with a standard carbon steel piston rod and PT tapered port threads. Because it lacks an internal magnet, external magnetic switches cannot be used for position sensing. For high-temperature environments up to +70C, alternative seal compounds such as Viton (H) are available to replace the standard TPU seals.

Where the Airtac SAI100 Standard Air Cylinder SAI100X150 Is Used
Heavy Stamping
Provides the necessary 3927N thrust at 0.5MPa for pressing and stamping rigid metal components in automated fabrication cells.
Pallet Diversion
Generates enough force to push heavy loaded pallets across heavy-duty roller conveyors without stalling or requiring maximum system pressure.
Press Fixture
Ideal for securely clamping large workpieces into stationary machining fixtures, utilizing its 150mm stroke to clear the work area during part loading.
Is the Airtac SAI100 Standard Air Cylinder SAI100X150 the Right Cylinder?
Choose this 100mm bore when the 80mm variant (providing 2513N push at 0.5MPa) lacks sufficient thrust for your heavy loads. If the 150mm stroke is excessive for your space constraints, dropping to a 100mm bore with a 100mm stroke offers a more compact footprint while retaining the same force class. Because the stroke is 150mm, side-load bending on the rod bearing is minimal, but external guides should still be used for perfectly square load alignment.
As a true ISO 15552 profile cylinder, this model serves as a drop-in replacement for any standard 100x150 unit with a G1/2 port and PT threads. It includes adjustable air cushions at both ends to decelerate the piston. Note that the standard SAI does not hold its load if air pressure is lost; for fail-safe holding, consider the SAIL variant with an air-released lock or an external pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI100 Standard Air Cylinder SAI100X150 FAQ
At 0.5MPa, this 100mm bore cylinder provides a push force of 3927N and a pull force of 3681N. If operated at 0.7MPa, the push force increases to 5497N.
No, the standard SAI series does not feature a locking mechanism and the piston will drift if air pressure is lost. The adjustable air cushion only decelerates the rod near the stroke end. For secure vertical load holding without live pressure, use the SAIL variant with an air-released lock or a BSAI clamp-lock cylinder.
