Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X100S
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X100S is a genuine double-acting ISO 15552 profile cylinder with a Ø100mm bore, 100mm 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 SAILF100X100S
The AirTAC SAILF100X100-S is a double-acting ISO 15552 profile cylinder equipped with a built-in mechanical lock inside the front cover. Because this is a SAILF variant, the spring-applied, air-released lock engages when the piston reaches the extended stroke end. It securely holds the rod out without requiring continuous live air pressure. Delivering 5497N of push force at 0.7 MPa, this 100mm bore unit uses a carbon steel rod and includes a magnet for position sensing.
The lock is a static holding device, not a dynamic brake for a moving rod. A key design trait is that the variable air cushion at the locker end is shorter (24mm) compared to the free end (36mm). To unlock, supply air to the release port for automatic retraction or use the manual release lever. The integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic 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 (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 SAILF100X100S Is Used
Extended Load Holding
Maintains an extended vertical load safely during power loss or air pressure drop without needing continuous supply.
Safety Gate Hold
Locks a guard or gate open at the extended stroke end, requiring an intentional air signal to close.
Clamp and Hold
Secures a workpiece at the outward stroke terminal, ensuring zero drift during machining operations.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X100S the Right Lock Cylinder?
Choose this 100mm bore cylinder when an application requires 5497N of push force at 0.7 MPa, stepping up from the 80mm bore which provides 3518N. If your load requires holding at the retracted position instead of extended, select the SAILB variant. If the mechanism must lock at an arbitrary mid-stroke point rather than a stroke end, the BSAI clamp-lock cylinder is the correct choice.
Remember that the lock holds statically only after the cylinder stops. Avoid using fast-exhaust valves, as back-pressure on the locker side can unintentionally release the lock; an independent-exhaust solenoid valve is required. For safety-critical suspended loads, add an independent mechanical safety measure. Replacement matches require 100mm bore, 100mm stroke, front locker, 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 SAILF100X100S FAQ
At 0.7 MPa operating pressure, the 100mm bore provides 5497N of push force and 3681N of pull force. The maximum operating pressure is 1.0 MPa.
The lock is spring-applied and air-released, engaging statically only when the piston reaches the extended stroke end. It is unlocked automatically by supplying air to the release port or manually via the lever. It does not clamp at mid-stroke.
