Airtac SAILF Front Locking Pneumatic Cylinder SAILF80X160
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF80X160 is a genuine double-acting ISO 15552 profile cylinder with a Ø80mm bore, 160mm 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 SAILF80X160
The AirTAC SAILF80X160 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 rod-out position without requiring live air pressure. With a robust 25mm carbon steel rod and a push force of 2513N at 0.5MPa, it delivers reliable performance for heavy load manipulation.
Because the lock occupies the front end, the variable air cushion on that locker side is shorter at 22.5mm compared to the 36mm cushion on the free back end. The lock releases automatically via air supply to the release port or manually via a lever, but avoid using fast-exhaust valves as back-pressure on the locker side can unintentionally release the lock.

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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 SAILF80X160 Is Used
Vertical Lift Hold
Maintains an extended vertical load safely in place during a power loss or air pressure drop.
Flow Control Gate
Locks a diverter gate open at the extended stroke end to keep materials moving without constant air supply.
Safety Barrier
Holds a protective guard in the fully extended position until an air signal deliberately releases the lock.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF80X160 the Right Lock Cylinder?
Choose this 80mm bore cylinder when your application demands a static hold at the rod-out position and requires up to 2513N of push force at 0.5MPa. If your load must be held at the retracted stroke end instead, select the SAILB80X160. For applications requiring the load to be clamped at an arbitrary mid-stroke position rather than a stroke terminal, the BSAI clamp-lock cylinder is the correct choice. If human safety depends on the load staying extended, add an independent safety measure alongside this lock.
For replacement matching, verify the 80mm bore, 160mm stroke, front locker position, 3/8 PT port thread, and your required mounting style from the ISO 15552 options. This model does not include a magnet for sensors; if position feedback is needed, add the -S option to use CMSE reed or DMSE electronic solid-state switches.
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 SAILF80X160 FAQ
At 0.5 MPa, the push force is 2513N and the pull force is 2268N. At 0.7 MPa, the push force increases to 3518N.
The lock is spring-applied and air-released, engaging only at the extended stroke end to hold the load statically. It is not a mid-stroke clamp or dynamic brake. It unlocks automatically via air pressure or manually via a lever.
