About the Airtac SAI100 Standard Air Cylinder SAI100X540S
The AirTAC SAI100X540-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 540mm stroke. It delivers a robust 3927 N of push force at 0.5 MPa, extending to 5497 N at 0.7 MPa. This specific 540mm stroke is a non-standard made-to-order length, engineered for applications requiring extended linear reach beyond the typical 500mm increments.
Equipped with a standard carbon steel piston rod and a -S magnet, this extruded aluminum barrel includes dual sensor grooves for direct mounting of CMSE or DMSE reed switches. The standard PT tapered port threads ensure a tight, leak-free pneumatic connection. Adjustable air cushions at both ends decelerate the piston smoothly, protecting your machinery from impact at stroke endpoints.

Where the Airtac SAI100 Standard Air Cylinder SAI100X540S Is Used
Extended-Reach Pressing
Applies 5497 N of thrust at 0.7 MPa for pressing bearings or pins over a long 540mm travel distance in large automated assembly lines.
Long-Stroke Diverting
Actuates heavy-duty diverter arms on wide conveyor belts, utilizing the 100mm bore's push force to move substantial product loads.
Large Material Lift
Raises heavy pallets or chassis components through 540mm of vertical travel, relying on adjustable cushions to cushion the payload at stroke end.
Is the Airtac SAI100 Standard Air Cylinder SAI100X540S the Right Cylinder?
Select this 100mm bore when a 80mm cylinder (providing 2513 N at 0.5 MPa) lacks the necessary thrust for heavier payloads, but stepping up to a 125mm bore (6136 N at 0.5 MPa) would be excessive. The 540mm stroke provides tailored travel for custom machine spacing. Because this stroke exceeds 300mm, the extended rod is highly susceptible to bending under side loads; always utilize an external guide rail or a dedicated guided cylinder to prevent premature rod-bearing wear.
This unit serves as a direct, dimensionally interchangeable drop-in replacement for other ISO 15552 profile cylinders. It features a G1/2 port, an M20x1.5 rod thread, and is fully compatible with standard FA/FB flanges or TC trunnion mounts. Note that a standard SAI cannot hold a load if air pressure is lost; for fail-safe position holding, explore the SAIL locking variant 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.
