About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X160
The AirTAC SAILF160X160 is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released mechanical lock housed in the front cover. This integrated lock engages automatically when the piston reaches the extended stroke end, securely holding the load without requiring live air pressure. With a robust 160mm bore, it generates a substantial push force of 18095N at 0.9MPa, making it ideal for heavy-duty positioning tasks. The standard carbon steel rod provides excellent durability for industrial environments.
Unlike a plain SAI cylinder, this model ensures power-loss safety by maintaining position at the rod-out terminal. The variable air cushion at the locker end is specifically machined shorter at 28mm compared to the 50mm cushion on the free end, optimizing the locking mechanism space. For position feedback, adding the -S magnet option allows compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors.

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 SAILF160X160 Is Used
Extended Load Holding
Secures heavy vertical loads in the rod-out position during power loss or emergency stops, preventing sudden drops.
Heavy Press Positioning
Maintains precise extended positioning for large pressing or clamping operations without consuming continuous air supply.
Safety Gate Hold
Keeps heavy safety gates and industrial barriers firmly locked in the open, extended state until released by air.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X160 the Right Lock Cylinder?
Select this 160mm bore cylinder when an application demands high thrust combined with secure holding at the extended stroke end. If the required force is lower, stepping down to the 125mm bore yields 11045N at 0.9MPa while saving space. Choose the SAILF configuration specifically when the load must be held in the extended position; conversely, select SAILB for retracted holding. If your process requires locking at an arbitrary mid-stroke point rather than the stroke end, the BSAI clamp-lock cylinder is the correct alternative.
Remember that this SAIL lock is a static holding device that engages after the cylinder stops, not a dynamic brake for a moving rod. Because back-pressure on the locker side can inadvertently release the lock, avoid using fast-exhaust valves and instead utilize an independent-exhaust solenoid valve. For safety-critical vertical loads that could endanger personnel if dropped, always add an independent mechanical safety measure. Replacement matches require a 160mm bore, 160mm stroke, front lock position, PT tapered ports, and standard mounting options like FA, FB, or 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 SAILF160X160 FAQ
At 0.9MPa operating pressure, the 160mm bore generates a push force of 18095N and a pull force of 9425N. The maximum operating pressure is 1.0MPa.
The lock is spring-applied and air-released, engaging only when the piston reaches the extended stroke end in the front cover. It provides a static hold after the rod stops, not a dynamic brake. Unlocking requires supplying air to the release port or using the manual override lever.
