About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF80X100
The AirTAC SAILF80X100 is a double-acting ISO 15552 profile cylinder featuring a built-in mechanical lock housed in the front cover. Because it is a SAILF variant, the spring-applied, air-released lock engages when the piston reaches the extended stroke end, securely holding the rod out without relying on continuous live air pressure. In the 80mm bore class, it generates 2513N of push force and 2268N of pull force at 0.5 MPa, utilizing a 25mm carbon steel rod for robust side-load resistance.
This cylinder uses a 3/8 PT port and includes variable air cushions at both ends. Note that the cushion at the locker end is physically shorter (22.5mm) compared to the free end (36mm) to accommodate the locking hardware. You can release the lock automatically by supplying air to the dedicated release port, or manually via the lever. For position sensing, adding a magnet allows the use of AirTAC CMSE reed or DMSE electronic 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 SAILF80X100 Is Used
Vertical Lift Hold
Maintains an elevated load at the extended stroke end during a power loss, preventing sudden drops without requiring constant air pressure.
Gate Retention
Keeps a heavy pneumatic gate locked in the open position, relying on the front cover mechanical lock until an air signal releases it.
Extended Clamp Hold
Holds a workpiece firmly extended while machining occurs, ensuring the rod stays locked out even if shop air pressure fluctuates.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF80X100 the Right Lock Cylinder?
Choose this 80mm bore when an application demands holding a load securely at the rod-out position; if you need to hold the rod in the retracted position instead, select the SAILB80X100. If your design requires clamping force at an arbitrary mid-stroke point rather than the terminal end, the BSAI clamp-lock cylinder is the correct choice. Stepping down to a 63mm bore reduces the push force to 1559N at 0.5 MPa, while upgrading to a 100mm bore increases it to 3927N.
The SAILF lock is a static holding device that engages only after the cylinder has stopped moving, not a dynamic brake for a moving rod. Valve selection is critical: never use a fast-exhaust valve with this cylinder, as back-pressure on the locker side can inadvertently release the lock—always use an independent-exhaust solenoid valve. If human safety depends on the load remaining extended, add an independent safety measure. Replacement matches must verify the 80mm bore, 100mm stroke, front locker position, 3/8 PT ports, and the desired mounting style (Basic, FA, FB, CA, CB, CR, LB, TC, FTC, TCM1, or TCM2).
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 SAILF80X100 FAQ
At 0.5 MPa operating pressure, the 80mm bore provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The lock is spring-applied and air-released, engaging only at the extended stroke end to hold the rod statically. It unlocks automatically via air supply to the release port or manually via a lever, but it cannot hold the rod at a mid-stroke position.
