Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X200S
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X200S is a genuine double-acting ISO 15552 profile cylinder with a Ø100mm bore, 200mm 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 SAILF100X200S
The AirTAC SAILF100X200-S is a double-acting ISO 15552 profile cylinder with a built-in mechanical lock housed in the front cover. Because the lock is spring-applied and air-released, cutting the release air drives a lock pin into the rod, securing the load at the extended stroke end without relying on live pressure. In this 100mm bore class, the cylinder generates 5497N of push force at 0.7MPa, making it well-suited for heavy-duty holding tasks. It includes a magnetic piston (-S) for precise position sensing using AirTAC CMSE reed or DMSE solid-state switches.
A key mechanical detail is that the variable air cushion at the locker end is shorter (24mm) than the free-end cushion (36mm). The cushion only decelerates the piston near the stroke terminal; the static lock is what actually holds the load. For safety-critical vertical applications, an independent mechanical stop is recommended alongside the lock.

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 SAILF100X200S Is Used
Vertical Load Holding
Secures elevated masses at the extended stroke end, preventing sudden drops during a power loss or pressure drop.
Clamp and Hold
Maintains outward clamping force on heavy workpieces without consuming continuous air supply pressure.
Gate and Lift Safety
Keeps heavy safety gates or lifting platforms firmly locked in the open position until air is actively supplied to release the pin.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X200S the Right Lock Cylinder?
Select this 100mm bore model when an application demands high load retention at the rod-out position; if lower force is acceptable, the 80mm bore provides 3518N at 0.7MPa. Choose SAILF for front-cover locking at the extended end, or SAILB if the load must be held retracted. If your process requires clamping at an arbitrary mid-stroke point rather than the stroke terminal, select the BSAI clamp-lock cylinder instead.
When integrating this cylinder, avoid using a fast-exhaust valve, as back-pressure on the locker side can unintentionally release the lock; an independent-exhaust solenoid valve is required. To replace this unit, match the 100mm bore, 200mm stroke, front lock position, PT tapered port threads, carbon steel rod, and the -S magnet option. The standard speed range is 30-800mm/s.
Quick checklist
- ✓ Hold needed at the extended (rod-out) end?
- ✓ Or lock anywhere → use BSAI
- ✓ Independent-exhaust valve fitted
- ✓ Port/thread type (PT/G)

Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X200S FAQ
At 0.7MPa, the push force is 5497N and the pull force is 3681N. At a maximum 1.0MPa operating pressure, the push force reaches 7068N.
The spring-applied, air-released lock engages when the piston reaches the extended stroke end in the front cover. It provides a static hold, not a dynamic brake. To unlock, supply air to the release port for automatic retraction or use the manual release lever.
