The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X1000 is a genuine double-acting ISO 15552 profile cylinder with a Ø100mm bore, 1000mm 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.
The AirTAC SAILF100X1000 is a double-acting ISO 15552 profile cylinder featuring a built-in spring-applied, air-released mechanical lock in the front cover. This lock engages automatically when the piston reaches the extended stroke end, securely holding the load without requiring continuous live air pressure. Removing the release air drives the lock pin into the carbon steel rod, and unlocking is achieved by supplying air to the release port or using the manual override lever.
Delivering 5497N of push force at 0.7 MPa, this 100mm bore unit operates at 30-800 mm/s. The variable air cushion at the locker end is 24mm, which is shorter than the 36mm cushion on the free end to accommodate the locking mechanism. For position sensing, the standard version ships without a magnet, but adding the -S option enables compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors.

Specifications follow the official AirTAC SAIL datasheet (ISO 15552). Confirm against the product label before installation. Port options: PT / G.
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.

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.
Maintains heavy lifted loads in the extended position during power loss, preventing crashes without consuming continuous compressed air.
Secures extended diverter gates or long-stroke stops at the end of travel, using the mechanical lock to resist external shocks.
Holds a safety barrier or guard open at the stroke end, requiring an intentional air release signal to unlock and close.
Choose this 100mm bore when an application requires 5497N of thrust at 0.7 MPa, stepping up from an 80mm bore that provides 3518N, or down from a 125mm bore offering 8590N. Select the SAILF configuration when the load must be held safely at the extended rod-out position; for holding at the retracted position, a SAILB is required instead. Because this is a 1000mm stroke, it exceeds the 1500mm maximum standard stroke for this bore, classifying it as non-standard, and the extended length necessitates a side-load guide to prevent rod bending.
The lock provides a static hold only after the cylinder has stopped at the stroke end; it is not a dynamic brake for a moving rod, nor does it clamp at an arbitrary mid-stroke point (use a BSAI clamp-lock for that). Valve selection is critical: do not use a fast-exhaust valve, as back-pressure on the locker side can inadvertently release the lock. Always use an independent-exhaust solenoid valve, and add an independent safety measure if human safety depends on the load staying elevated.
Quick checklist
The 100mm bore generates 3927N push and 3681N pull at 0.5 MPa, and 5497N push at 0.7 MPa. The maximum operating pressure is 1.0 MPa.
The lock is spring-applied and air-released, engaging only when the rod reaches the fully extended stroke end. It provides a static hold, not a mid-stroke clamp. It unlocks automatically via air supply to the release port or manually via the lever, and requires an independent-exhaust solenoid valve to prevent accidental release from back-pressure.
