About the Airtac SAI100 Standard Air Cylinder SAI100AX185
The AirTAC SAI100X185 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 185mm stroke. It delivers a robust push force of 3927N at 0.5MPa, making it well-suited for heavy-duty pressing and clamping operations.
This model features a SUS420J2 stainless steel rod, offering excellent corrosion resistance for humid or mildly chemically exposed environments. The extruded aluminum barrel includes sensor grooves on both sides for CMSE or DMSE switches, though a magnet must be specified separately if position detection is required.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX185 Is Used
Heavy-Duty Pressing
Provides 3927N of thrust at 0.5MPa for assembling bearings and seating components securely in automated presses.
Industrial Clamping
Holds large metal or composite workpieces firmly during machining, welding, or adhesive curing processes.
Material Handling
Actuates heavy diverters and sorting gates on high-capacity conveyor lines with reliable 100mm bore power.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX185 the Right Cylinder?
If your application requires less force, stepping down to an 80mm bore yields 2513N at 0.5MPa, while the 125mm bore offers 6136N for heavier loads. The 185mm stroke is well below the 1500mm maximum, so standard rod-bearing bending is not a primary concern.
For drop-in compatibility, match the 100mm bore, 185mm stroke, PT G1/2 port, and your required mounting accessory such as an FA flange or LB foot. Note that this standard cylinder relies on adjustable air cushions to decelerate the piston at stroke end; it does not hold loads pneumatically. If your system loses pressure, the rod will drift, so consider the SAIL variant for positive locking.
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 SAI100AX185 FAQ
The SAI100X185 generates a push force of 3927N at 0.5MPa and 5497N at 0.7MPa, with a theoretical maximum force of 801 kgf at 1.0MPa.
Yes, its standardized ISO 15552 mounting interface makes it dimensionally interchangeable with other profile-type ISO 15552 cylinders, provided you match the 100mm bore, 185mm stroke, and G1/2 ports.
