The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X1000 is a genuine double-acting ISO 15552 profile cylinder with a Ø160mm 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 SAILF160X1000 is a double-acting ISO 15552 profile cylinder equipped with a spring-applied, air-released mechanical lock housed in the front cover. This mechanism engages automatically to hold the rod securely at the extended stroke end whenever the release air is cut, dropping the load safely without relying on live pressure. With a robust 40 mm carbon steel rod and a substantial 10053 N push force at 0.5 MPa, it is built for heavy-duty load manipulation.
Because this unit features a long 1000 mm stroke, guiding the load against side-load forces is critical to prevent rod binding and premature seal wear. The variable air cushion at the locker end is specifically machined shorter (28 mm) compared to the free end (50 mm) to accommodate the locking hardware. For position sensing, adding a magnet allows the use of AirTAC CMSE reed or DMSE electronic sensors in the dual barrel grooves.

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 |

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.
Secures elevated platforms or heavy lifting arms at the fully extended stroke end, preventing sudden drops if air pressure is lost during operation.
Spring-applied lock instantly engages upon loss of release air to freeze the rod in the extended position, protecting operators and workpieces during power outages.
Maintains constant clamping pressure on large fabricated parts at the end of the stroke without consuming continuous compressed air, saving energy.
Choose this 160 mm bore when an application demands high thrust—such as the 14074 N push force generated at 0.7 MPa—and a failsafe hold at the rod-out position. If your load requires less force, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa, whereas moving up to a 200 mm bore provides 21991 N. Select the SAILF configuration when the extended position is the safety-critical state; opt for SAILB if the retracted rod-in position must be held instead.
Remember that this lock is a static holding device that engages only after the cylinder stops at the stroke terminal; it is not a mid-stroke clamp or a dynamic brake. If your process requires clamping at an arbitrary intermediate position, use the AirTAC BSAI clamp-lock cylinder instead. To maintain lock integrity, never use a fast-exhaust valve, as back-pressure on the locker side can inadvertently release the pin; always utilize an independent-exhaust solenoid valve. Finally, if human safety depends on the load remaining elevated, install an independent mechanical safety measure as a backup. Replacement matches must align on bore, stroke, front locker position, PT port threads, and mounting style.
Quick checklist
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. If the operating pressure is increased to 0.7 MPa, the push force rises to 14074 N.
The lock is spring-applied and air-released, holding the rod statically at the extended stroke end. It engages after the piston stops and is released by supplying air to the release port or by using the manual release lever.
