The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X1000S 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-S is a double-acting ISO 15552 profile cylinder featuring a built-in mechanical lock in the front cover. Because the lock is spring-applied and air-released, cutting the release air drives a pin into the rod to securely hold the load at the extended stroke end without consuming live pressure. You can unlock it automatically by supplying air to the release port or by using the manual release lever. Equipped with a magnetic piston, it supports AirTAC CMSE reed and DMSE solid-state sensors for precise end-position detection.
This 100mm bore generates 5497N of push force and 3681N of pull force at 0.7 MPa. The carbon steel rod provides robust side-load capability for heavy guiding tasks. Note that the variable air cushion at the front locker end is 24mm, intentionally shorter than the 36mm cushion at the rear free end. The lock is a static holding device that engages after the cylinder stops; it is not a dynamic brake for a moving rod.

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 vertical loads securely at the extended rod-out stroke end during a power loss event, preventing sudden drops without needing continuous air pressure.
Acts as a rigid stop barrier for materials on an overhead conveyor, holding the extended position firmly against accumulated load weight.
Keeps heavy safety gates and machine access doors locked in the open, extended position until the release air is actively supplied.
Choose this 100mm bore for loads requiring substantial thrust, stepping up from an 80mm bore that yields 3518N push at 0.7 MPa. Select the SAILF configuration when your application requires the load to be safely held at the extended rod-out position. If your process requires clamping at an arbitrary mid-stroke point instead of the stroke terminal, choose the BSAI clamp-lock cylinder instead. This model features a PT tapered port thread and uses the full ISO 15552 mounting interface set (Basic, FA, FB, CA, CB, CR, LB, TC, FTC, TCM1, TCM2).
Because this 1000mm stroke exceeds the 1500mm standard maximum, it is a non-standard unit requiring a side-load guide to prevent rod bending over the extended travel. Remember that the lock holds the load statically at the stroke end without live air; the cushion only decelerates the piston and never acts as the holding device. For valve selection, never use a fast-exhaust valve with this lock cylinder; use an independent-exhaust solenoid valve, as back-pressure on the locker side can accidentally release the lock. If human safety depends on the load staying extended, always add an independent safety measure.
Quick checklist
At 0.7 MPa, this 100mm bore cylinder provides 5497N of push force and 3681N of pull force. It achieves a maximum push of 7068N at 0.9 MPa.
The lock is spring-applied and air-released, holding the rod statically at the extended stroke end when release air is cut. It is not a mid-stroke clamp or a dynamic brake. Unlock it automatically via air or manually via the lever, but never use a fast-exhaust valve, as back-pressure can release the lock.
