Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X700
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X700 is a genuine double-acting ISO 15552 profile cylinder with a Ø160mm bore, 700mm 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 SAILF160X700
The AirTAC SAILF160X700 is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released mechanical lock housed in the front cover. This lock engages automatically when the piston reaches the extended stroke end, securely holding a load of up to 14074N at 0.7MPa without requiring continuous live air pressure. The extruded aluminum barrel design is dimensionally interchangeable per ISO 15552 mounting interfaces, though the integrated lock mechanism adds length beyond a standard non-lock cylinder.
Because the lock is situated at the front end, the variable air cushion on that locker side is notably shorter at 28mm compared to the 50mm cushion on the free back end. The cylinder operates within a 30-500 mm/s speed range and uses a PT threaded 3/4 port with a 40mm carbon steel rod. For position detection, adding a magnet allows the use of CMSE reed or DMSE solid-state sensors in the dual-side barrel grooves.

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 (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 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 SAILF160X700 Is Used
Overhead Lifter Safety
Secures heavy vertical loads in the extended position instantly upon air pressure loss, preventing sudden drops on overhead lifting rigs.
Heavy Clamp Hold
Maintains high-force clamping pressure on large fabricated components at the stroke end without continuously consuming compressed air.
Gate Barrier Lock
Holds heavy industrial safety gates firmly in the open extended position during power loss until air is actively supplied to release.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X700 the Right Lock Cylinder?
Choose this 160mm bore when substantial thrust is needed for heavy lifting or clamping, offering 10053N pull force at 0.5MPa. If your application requires less force, stepping down to a 125mm bore provides 5734N pull at 0.5MPa. Select the SAILF configuration when the load must be safely held at the fully extended rod-out position, whereas SAILB secures the retracted rod-in position. If your process demands locking at an arbitrary mid-stroke point rather than the stroke end, the BSAI clamp-lock cylinder is the correct choice instead.
Remember that this is a static holding lock, 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 unintentionally release the lock; always use an independent-exhaust solenoid valve. Additionally, if human safety depends on the load remaining elevated, implement an independent safety measure. For this 700mm stroke, ensure external guide rails are used to prevent excessive side-load wear on the rod and seals.
Quick checklist
- ✓ Hold needed at the extended (rod-out) end?
- ✓ Or lock anywhere → use BSAI
- ✓ Independent-exhaust valve fitted
- ✓ Port/thread type (PT/G)
- ✓ Extra safety measure for people
Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X700 FAQ
The 160mm bore generates a push force of 14074N at 0.7MPa and 18095N at 0.9MPa. The pull force is 9425N at 0.5MPa and 18095N at 0.9MPa.
The spring-applied, air-released lock engages only at the extended stroke end to hold the load statically. It unlocks automatically via air supply to the release port or via a manual lever. It does not clamp mid-stroke.
