About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF80X600
The AirTAC SAILF80X600 is a double-acting ISO 15552 profile cylinder featuring a mechanical lock integrated into the front cover. Because the lock is spring-applied and air-released, cutting the release air drives a lock pin into the carbon steel rod, securely holding the load at the extended stroke end without requiring live pressure. You can unlock it automatically by supplying air to the release port or by using the manual release lever. Delivering a robust 2513N push force at 0.5MPa, it provides reliable power for heavy positioning tasks.
The lock engages only after the piston reaches the extended stroke terminal, functioning as a static holding device rather than a dynamic brake for a moving rod. To manage deceleration, the variable air cushion at the locker end measures 22.5mm, which is intentionally shorter than the 36mm cushion on the free end. For position sensing, the barrel features dual sensor grooves compatible with AirTAC CMSE reed and DMSE electronic switches, though this specific unit is supplied without a magnet.

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 SAILF80X600 Is Used
Vertical Lift Safety
Holds an extended vertical load securely in place during a sudden air pressure loss, preventing accidental drops on lifting platforms.
Flow Control Diverter
Locks a diverter arm in the extended rod-out position to route heavy packages on a conveyor without requiring continuous air pressure.
Machine Guard Hold
Maintains a safety guard or gate open at the full extended stroke end, ensuring it remains stationary until a controlled air release signal is sent.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF80X600 the Right Lock Cylinder?
Choose this 80mm bore cylinder when an application requires holding a load at the extended stroke end during a power loss, as the SAILF variant secures the rod-out position. If your process demands holding the retracted position instead, select the SAILB equivalent. For applications needing the rod clamped at an arbitrary mid-stroke point rather than the stroke terminal, the BSAI clamp-lock cylinder is the correct choice.
When specifying this 600mm stroke model, always pair it with an external guide mechanism to prevent excessive side loads on the rod. To maintain lock integrity, never use a fast-exhaust valve; instead, install an independent-exhaust solenoid valve, because back-pressure on the locker side can unintentionally release the lock. If human safety depends on the load remaining elevated, always add an independent mechanical safety measure. Replacement units must match the 80mm bore, 600mm stroke, front locker position, PT port threads, and the chosen mounting style.
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 SAILF80X600 FAQ
At a 0.5MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7MPa, the push force increases to 3518N.
The lock is spring-applied and air-released, engaging only when the piston reaches the extended stroke end in the front cover. It provides a static hold after the rod stops, not a mid-stroke clamp, and can be unlocked automatically via air or manually via a lever.
