The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X100S is a genuine double-acting ISO 15552 profile cylinder with a Ø200mm bore, 100mm 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 SAILF200X100-S is a double-acting ISO 15552 profile cylinder equipped with a mechanical lock in the front cover. It delivers 15708N of push force and 15080N of pull force at 0.5 MPa. The lock is spring-applied and air-released, meaning it engages automatically to hold the rod securely at the extended stroke end whenever release air is cut, ensuring the load stays out without relying on live pressure. A manual release lever provides backup unlocking capability.
Because the lock occupies the front end, the variable air cushion on that side is shorter, measuring 28mm compared to the 50mm cushion on the free end. This extruded aluminum barrel includes a magnet for CMSE reed and DMSE electronic sensors, and uses a carbon steel rod with PT tapered port threads. It is dimensionally interchangeable per ISO 15552 mounting interfaces, though the lock mechanism adds length beyond a standard cylinder.

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.
| Pressure | Push force | Pull force |

| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 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.
Maintains an elevated load at the extended stroke end during a power loss, preventing sudden drops without needing continuous air pressure.
Holds heavy workpieces firmly in the extended position after the cylinder stops, ensuring the part stays clamped if air supply is interrupted.
Keeps a protective gate or barrier locked in the open, extended position until the release air is deliberately supplied to unlock it.
Choose this 200mm bore when your application demands high thrust, such as 21991N at 0.7 MPa, alongside a safety hold at the rod-out position. If your load requires less force, stepping down to a 160mm bore yields 10053N at 0.5 MPa. Select the SAILF configuration only when you need the load secured at the extended stroke end; if you need the rod held retracted, the SAILB variant is required instead. For clamping at an arbitrary mid-stroke point, a BSAI clamp-lock cylinder is the correct choice.
Remember that this lock is a static holding device that engages after the cylinder stops, 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 accidentally release the lock. Always use an independent-exhaust solenoid valve. If human safety depends on the load remaining extended, add an independent safety measure. When replacing, match the 200mm bore, 100mm stroke, front lock position, 3/4 inch PT port, and the -S magnet option.
Quick checklist
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers a maximum push force of 3204 kgf.
The lock is spring-applied and air-released, holding the rod securely at the extended stroke end when air is cut. It unlocks automatically by supplying air to the release port or manually via a lever. It is a static hold, not a mid-stroke clamp or dynamic brake.
