About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X75S
The AirTAC SAILF160X75-S is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released mechanical lock housed in the front cover. Because the lock sits on the rod-out side, it engages automatically to hold the load securely at the extended stroke end whenever release air is cut. Delivering a substantial 14074 N of push force at 0.7 MPa, this carbon-rod actuator is built for heavy-duty power-loss safety.
This unit includes a magnetic piston (-S) for precise position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors. A key design detail is the variable air cushion: the locker-end cushion spans 28 mm, intentionally shorter than the 50 mm cushion on the free end, to accommodate the locking mechanism. The lock is a static holding device, not a dynamic brake, and safely secures the rod only after the cylinder has stopped moving.

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 SAILF160X75S Is Used
Heavy Press Hold
Maintains tonnage on a hydraulic press ram at the extended stroke end during power loss, preventing accidental retraction.
Vertical Lift Safety
Secures a raised heavy platform or lift in the extended position without relying on continuous live air pressure.
Clamp and Secure
Holds a heavy workpiece firmly extended at the end of stroke during machining or welding operations.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X75S the Right Lock Cylinder?
Choose this 160 mm bore when an application demands high thrust—stepping down to a 125 mm bore drops the 0.5 MPa push force to 6136 N, whereas this size yields 10053 N. Select the SAILF configuration when the load must be held at the extended stroke end; if you need to secure the load retracted, choose SAILB. For applications requiring the rod to be clamped at an arbitrary mid-stroke position, the BSAI clamp-lock cylinder is the correct choice instead.
When integrating this actuator, adhere to strict valve-selection red-lines: never use a fast-exhaust valve, and always specify an independent-exhaust solenoid valve. Back-pressure on the locker side can inadvertently release the lock. The 3/4 PT port matches the bore size. If human safety depends on the load staying extended, always add an independent mechanical safety measure alongside the cylinder lock.
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 SAILF160X75S FAQ
At 0.7 MPa operating pressure, the 160 mm bore provides a push force of 14074 N and a pull force of 9425 N. The maximum push force is 18095 N at 0.9 MPa.
The lock is spring-applied and air-released, engaging only at the extended stroke end after the rod stops moving. It is a static hold, not a dynamic brake. To unlock, supply air to the release port for automatic release or use the manual release lever.
