About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X175
The AirTAC SAILF160X175 is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released mechanical lock built into the front cover. This lock engages automatically when the piston reaches the extended stroke end, ensuring your load is held securely without requiring continuous live air pressure. Delivering a robust 14074N push force at 0.7 MPa, it is engineered for heavy-duty holding tasks.
Because the lock resides in the front end, the variable air cushion on that locker side is shorter (28 mm) compared to the free end (50 mm). The cylinder uses a carbon steel rod and PT tapered ports. To release the rod, simply supply air to the release port or use the manual override lever. For position sensing, adding a -S magnet enables compatibility with CMSE reed and DMSE 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 SAILF160X175 Is Used
Vertical Load Holding
Secures heavy elevated loads at the extended stroke end automatically upon air pressure loss, preventing sudden drops in lifting rigs.
Power-Out Safety Gate
Keeps heavy safety gates and barriers locked in the open extended position during power or air supply failures.
Heavy Press Hold
Maintains high-force clamping pressure on large fabricated parts at the stroke terminal without consuming continuous compressed air.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X175 the Right Lock Cylinder?
Choose this 160 mm bore when substantial thrust is required; if your application needs less force, stepping down to a 125 mm bore provides 8590N push at 0.7 MPa. Select the SAILF configuration when the load must be held at the extended rod-out position, whereas a SAILB variant holds at the retracted end. If your process requires locking at an arbitrary mid-stroke point rather than the stroke terminal, the BSAI clamp-lock cylinder is the correct alternative.
Remember that this is a static holding lock that engages after the cylinder stops, not a dynamic brake for a moving rod. Avoid using fast-exhaust valves, as back-pressure on the locker side can unintentionally release the lock; always use an independent-exhaust solenoid valve. If human safety depends on the load remaining extended, add an independent safety measure. To replace this unit, match the 160 mm bore, 175 mm stroke, front locker position, PT ports, and your required mounting style from the full ISO 15552 set.
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 SAILF160X175 FAQ
At 0.7 MPa operating pressure, the 160 mm bore provides 14074N of push force and 14074N of pull force. The maximum operating pressure is 1.0 MPa.
The lock is spring-applied and air-released. It engages statically when the rod reaches the extended stroke end, holding the load without live pressure. Supply air to the release port or use the manual lever to unlock it.
