About the Airtac SAI100 Standard Air Cylinder SAI100X275S
The AirTAC SAI100X275-S is a double-acting profile cylinder built to strict ISO 15552 dimensional standards, ensuring seamless drop-in compatibility with other standard ISO 15552 actuators. Operating on filtered air, it delivers a robust 3927 N push force at 0.5 MPa and features a 275 mm stroke suited for heavy-duty material handling.
This specific configuration includes a magnetic piston (-S) for use with CMSE or DMSE reed switches, which mount directly into the dual sensor grooves on the extruded aluminum barrel. The standard carbon steel piston rod provides excellent structural strength for high-cycle automation.

Where the Airtac SAI100 Standard Air Cylinder SAI100X275S Is Used
Heavy-Duty Pressing
Provides reliable 3927 N force at 0.5 MPa for pressing bearings and pins into heavy housings.
Pallet Diverting
Uses the 275 mm stroke and magnetic piston to push heavy pallets off high-speed packaging lines.
Automated Clamping
Secures large metal workpieces during machining operations, utilizing the robust carbon steel rod.
Is the Airtac SAI100 Standard Air Cylinder SAI100X275S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant significantly increases thrust, stepping up from 2513 N to 3927 N at 0.5 MPa. For applications requiring less force and faster cycling, the 80 mm bore is a viable alternative. Because the 275 mm stroke is non-standard, expect a made-to-order lead time.
This model uses a PT tapered G1/2 port. While the adjustable air cushions decelerate the piston at both ends, they do not lock the rod; if pressure is lost, the load will drift. For position holding without live pressure, consider the SAIL variant with an air-released lock. Additionally, while the 275 mm stroke is moderate, always manage side loads with external guides to prevent rod-bearing bending.
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 SAI100X275S FAQ
At a standard 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force.
No, the standard adjustable air cushions only decelerate the piston at stroke ends and do not lock the load. For secure position holding without live air pressure, use the SAIL variant with an air-released lock.
