About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X225
The AirTAC SAILF160X225 is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released mechanical lock in the front cover. This built-in lock engages automatically when the piston reaches the extended stroke end, ensuring your load remains safely held without requiring continuous live air pressure. In this 160mm bore class, the cylinder generates a substantial 14074N of push force at 0.7MPa, making it well-suited for heavy-duty holding tasks.
The lock is a static holding device, not a dynamic brake that stops a moving rod. To release the load, supply air to the release port for automatic unlocking or use the manual override lever. Note that the variable air cushion at the locker end is 28mm, intentionally shorter than the 50mm cushion on the free end. For position feedback, adding a magnet allows the use of AirTAC CMSE reed or DMSE solid-state sensors in the dual barrel grooves.

How the Lock Holds
The lock is spring-applied and air-released: a spring drives a lock pin into the rod when the release air is removed, so the load is held at the extended (rod-out) stroke end without live pressure. Supply air to the release port to unlock automatically, or use the manual release lever.
The lock engages only when the piston reaches the stroke terminal on the front-cover side — it is a static end-of-stroke hold, not a mid-stroke clamp and not a moving-rod brake. For locking at any position along the stroke, choose a BSAI clamp-lock instead.
Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
Cylinder thrust is separate from the lock's holding capability. Actual usable force is lower than theoretical due to friction and back-pressure — size with a margin.
Where the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X225 Is Used
Extended Load Holding
Maintains heavy lifted loads in the extended position during power loss, preventing sudden drops on vertical actuators.
Clamp and Secure
Holds a workpiece firmly at the rod-out stroke end without consuming continuous air, saving energy during machining cycles.
Safety Gate Hold
Keeps heavy safety gates or barriers locked in the open extended position until a controlled air signal releases the pin.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X225 the Right Lock Cylinder?
Choose this 160mm bore if your application demands high thrust (14074N push at 0.7MPa) and a secure hold at the rod-out position. If your force requirements are lower, the 125mm bore offers 8590N at the same pressure; for heavier loads, the 200mm bore provides 21991N. Select the SAILF configuration specifically when the load must be held at the extended stroke end, whereas SAILB holds the retracted position. If your process requires locking at an arbitrary mid-stroke point rather than the terminal end, the BSAI clamp-lock cylinder is the correct choice instead.
Because this is a 225mm stroke, ensure adequate guiding to prevent excessive side loads on the carbon steel rod. The lock is a static device that engages after the cylinder stops. Avoid using fast-exhaust valves, as back-pressure on the locker side can inadvertently release the lock; always use an independent-exhaust solenoid valve. If human safety depends on the load staying elevated, add an independent mechanical safety measure. This unit features PT tapered ports and standard mounting options like FA, FB, and TC.
Quick checklist
- ✓ Hold needed at the extended (rod-out) end?
- ✓ Or lock anywhere → use BSAI
- ✓ Independent-exhaust valve fitted
- ✓ Port/thread type (PT/G)
- ✓ Extra safety measure for people
Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X225 FAQ
At 0.7MPa, this 160mm bore cylinder provides a push force of 14074N and a pull force of 9425N. The maximum operating pressure is 1.0MPa.
The lock is spring-applied and air-released. It engages statically only when the rod reaches the extended stroke end. To unlock, supply air to the release port or use the manual lever. It does not clamp mid-stroke.
