About the Airtac SAI125 Standard Air Cylinder SAI125X95
The AirTAC SAI125X95 is a double-acting ISO 15552 profile cylinder featuring a 125mm bore and a 95mm stroke. Because 95mm is not a standard factory increment, this unit is produced as a non-standard, made-to-order stroke. It delivers a robust 6136 N of push force at 0.5 MPa, making it well-suited for heavy-duty pressing and lifting tasks.
This variant is equipped with a standard carbon steel piston rod and PT tapered port threads. While this specific configuration lacks a magnet for proximity sensing, the extruded aluminum barrel retains sensor grooves on both sides for future upgrades if needed.

Where the Airtac SAI125 Standard Air Cylinder SAI125X95 Is Used
Heavy-Duty Stamping
Provides the 6136 N push force at 0.5 MPa required for metal forming and heavy stamping operations.
Automotive Assembly
Drives large clamping fixtures and heavy structural components during automotive manufacturing.
Pallet Diverter
Handles and diverts heavy-loaded pallets on high-capacity conveyor lines with precise movement.
Is the Airtac SAI125 Standard Air Cylinder SAI125X95 the Right Cylinder?
If 6136 N of push force at 0.5 MPa is insufficient, stepping up to the 160mm bore yields 10053 N. Conversely, dropping down to the 100mm bore provides 3927 N for lighter loads. Because this 95mm stroke is non-standard, expect a slightly longer lead time compared to standard 100mm increments.
As a double-acting actuator, this cylinder relies on continuous air pressure to hold its position. If your application requires static load holding during a complete air loss or valve centering, pair this cylinder with an external pilot-operated check valve or consider the SAIL variant which features an integrated air-released locking mechanism.

- ✓ 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.
