Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X700S
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X700S is a genuine double-acting ISO 15552 profile cylinder with a Ø100mm bore, 700mm 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 SAILF100X700S
The AirTAC SAILF100X700-S is a double-acting ISO 15552 profile cylinder equipped with a spring-applied, air-released mechanical lock housed in the front cover. Because the lock engages when the piston reaches the extended stroke terminal, it securely holds the rod-out position without requiring continuous live air pressure. Delivering a robust 5497N of push force at 0.7MPa, this 100mm bore unit is tailored for heavy vertical load retention. The integrated -S magnet enables precise position detection using AirTAC CMSE reed and DMSE solid-state sensors.
A key mechanical feature is the variable air cushion at both ends, though the cushion at the locker end is notably shorter at 24mm compared to the 36mm free end. The lock itself is a static holding device that engages only after the cylinder has fully stopped; it is not a dynamic brake for a moving rod. This design guarantees secure load maintenance upon power loss, though independent safety measures are advised for human-safety-critical applications.

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 SAILF100X700S Is Used
Extended Lift Holding
Maintains vertical lifts securely in the rod-out position during power loss, preventing sudden drops.
Safety Gate Lock
Keeps heavy safety barriers and access gates firmly extended and locked until pneumatic release is commanded.
Clamp and Hold
Secures workpieces at the outward stroke end for extended machining cycles without consuming continuous air.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X700S the Right Lock Cylinder?
Choose this 100mm bore when an application requires holding a substantial extended load, such as a 5497N push at 0.7MPa. If your force requirements are lower, stepping down to an 80mm bore yields 3518N at 0.7MPa, whereas a 125mm bore provides 8590N for heavier lifting. Select this SAILF model specifically when the rod must be secured in the extended outward position; a SAILB variant should be chosen instead if the load must be held retracted. If the mechanism requires clamping at an arbitrary mid-stroke point rather than the stroke terminal, AirTAC's BSAI clamp-lock cylinder is the correct solution.
With a 700mm stroke, this cylinder is susceptible to side-load deflection, so rigid guide rails or a self-aligning coupling are highly recommended to prevent rod binding. To maintain lock integrity, strictly avoid using a fast-exhaust valve, as back-pressure on the locker side can inadvertently release the lock; an independent-exhaust solenoid valve is required. Replacement requires matching the 100mm bore, 700mm stroke, front locker position, PT port threads, and the -S magnet option.
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 SAILF100X700S FAQ
At 0.7MPa, the push force is 5497N and the pull force is 3681N. At a maximum operating pressure of 1.0MPa, it achieves a push force of 801kgf.
The lock is spring-applied and air-released, engaging statically only when the piston reaches the extended stroke end. It holds the load without live pressure and unlocks via an air release port or manual lever; it does not clamp at mid-stroke.
