Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X160
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X160 is a genuine double-acting ISO 15552 profile cylinder with a Ø100mm bore, 160mm stroke and a built-in spring-applied, air-released mechanical lock in the front cover — it holds the load at the extended (rod-out) stroke end even when air is lost.

About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X160
The AirTAC SAILF100X160 is a double-acting ISO 15552 profile cylinder featuring a built-in mechanical lock in the front cover. Because the lock is spring-applied and air-released, it automatically engages a lock pin into the rod when the piston reaches the extended stroke end. This means your load is safely held without requiring live air pressure. In the 100mm bore class, this cylinder provides a robust 3927N push force and 3681N pull force at 0.5MPa, making it highly capable for heavy lifting duties.
A key mechanical detail is that the variable air cushion at the locker end is shorter (24mm) compared to the free end cushion (36mm). The lock itself is a static holding device that engages after the cylinder stops, rather than a dynamic brake for a moving rod. For position feedback, you can pair the magnetic piston variant with AirTAC CMSE reed or DMSE solid-state sensors in the dual-side 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SAILF100X160 Is Used
Vertical Lifting Safety
Secures elevated loads at the extended stroke end automatically upon air loss, preventing sudden drops in heavy lifting rigs.
Clamp and Hold
Maintains outward clamping pressure on heavy components without consuming continuous air, engaging the lock once the rod fully extends.
Gate and Guard Holding
Keeps safety barriers and heavy gates open at full extension until the release air is actively supplied to unlock the mechanism.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X160 the Right Lock Cylinder?
Choose this 100mm bore if your application demands more thrust than the 80mm bore (which provides 2513N push at 0.5MPa), but you do not require the heavier 125mm option (6136N push at 0.5MPa). Select the SAILF configuration when you specifically need the load secured at the extended rod-out position; if your safety requirement is holding the load retracted, choose the SAILB model instead. 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.
When integrating this model, remember the valve-selection red-line: do not use a fast-exhaust valve, and use an independent-exhaust solenoid valve. Back-pressure on the locker side can unintentionally release the lock. The lock holds statically at the extended end, so if human safety depends on the load staying up, add an independent safety measure. Replacement matching requires a 100mm bore, 160mm stroke, front locker position, PT port threads, 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 SAILF100X160 FAQ
At 0.5MPa operating pressure, the SAILF100X160 delivers 3927N of push force and 3681N of pull force. At 0.7MPa, the push force increases to 5497N.
The lock is spring-applied and air-released, holding the rod statically at the extended stroke end without live pressure. You can unlock it automatically by supplying release air to the port or by using the manual release lever.
