About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X200S
The AirTAC SAILF160X200-S is a double-acting ISO 15552 profile cylinder featuring a built-in mechanical lock in the front cover. Because this is a SAILF variant, the spring-applied, air-released lock engages automatically when the piston reaches the extended stroke end. It securely holds the rod-out position without requiring live pressure, delivering a robust 14074N of push force at 0.7 MPa and featuring a carbon steel rod.
This model includes a magnetic piston (-S) for position sensing with AirTAC CMSE reed and DMSE electronic sensors. The variable air cushion at the locker end measures 28 mm, which is shorter than the 50 mm cushion at the free end, ensuring precise deceleration before the mechanical lock engages. The lock is a static holding device, not a dynamic brake, and utilizes PT tapered port threads for pneumatic connections.

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 SAILF160X200S Is Used
Extended Lift Holding
Maintains a lifted load in the extended rod-out position during power loss, preventing sudden drops without needing continuous air pressure.
Safety Gate Lock
Secures a heavy safety barrier in the open position at the end of its stroke, keeping the pathway clear until air is supplied to release the lock.
Press Hold
Holds an extended press head in place under heavy load, ensuring the workpiece remains clamped at the stroke end during machine cycles.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X200S the Right Lock Cylinder?
Choose this 160 mm bore when substantial extended-rod holding force is required, or step down to the 125 mm bore (offering 8590N push at 0.5 MPa) if your load is lighter. Select this SAILF model to hold the rod in the extended position; if your application requires holding the retracted rod, choose SAILB instead. For applications needing the load clamped at an arbitrary mid-stroke point rather than the stroke end, the BSAI clamp-lock cylinder is the correct choice.
The lock engages only after the cylinder stops at the stroke terminal, meaning it will not stop a moving rod. Avoid using fast-exhaust valves with this cylinder; an independent-exhaust solenoid valve is required because back-pressure on the locker side can unintentionally release the lock. Always add an independent safety measure if human safety depends on the load remaining elevated. Replacement matches require a 160 mm bore, 200 mm stroke, front locker position, PT ports, and the -S magnet.
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 SAILF160X200S FAQ
At 0.7 MPa, the push force is 14074N and the pull force is 9425N. The maximum push force at 1.0 MPa is 2050 kgf.
The lock is spring-applied and air-released, holding the rod securely at the extended stroke end without live pressure. To unlock, supply air to the release port or use the manual release lever.
