About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X600
The AirTAC SAILF200X600 is a double-acting ISO 15552 profile cylinder featuring a built-in mechanical lock housed in the front cover. Because the lock is spring-applied and air-released, it safely holds the rod at the fully extended stroke end whenever release air is cut off, maintaining the load securely without requiring live pressure. Delivering a substantial 15708N push force at 0.5MPa, this 200mm bore unit uses a carbon steel rod and PT tapered port threads.
The lock engages statically after the piston stops, rather than acting as a dynamic brake for a moving rod. Notably, the variable air cushion at the locker end is shorter at 28mm compared to the free end, which accommodates the locking mechanism. For position sensing, adding a magnet allows the use of AirTAC CMSE reed or DMSE electronic sensors.

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 (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 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.
Where the Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X600 Is Used
Heavy Vertical Lifts
Secures heavy elevated loads at the extended stroke end on power loss, preventing sudden drops in large lifting rigs.
Press Hold Systems
Maintains maximum applied clamping force at the extended position without consuming continuous air pressure.
Gate Safety Barriers
Locks large industrial gates in the open position reliably, requiring an air signal to release the barrier.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X600 the Right Lock Cylinder?
Choose this 200mm bore model when an application demands immense thrust and guaranteed load holding at the extended stroke end. If your system only requires 10053N of push force at 0.5MPa, stepping down to the 160mm bore is more efficient, but this SAILF200X600 is required for heavy vertical lifts. Select the SAILF configuration when the rod must be locked in the extended position; choose SAILB if the retracted position must be held. If you need to clamp the load at an arbitrary mid-stroke point rather than the stroke end, the AirTAC BSAI clamp-lock cylinder is the correct choice instead.
Ensure correct valve selection: do not use a fast-exhaust valve, as back-pressure on the locker side can unintentionally release the lock; an independent-exhaust solenoid valve is required. Because this is a 600mm stroke, use an external guide to prevent excessive side-load wear on the rod. If human safety depends on the load remaining extended, always add an independent safety measure. To replace this unit, match the 200mm bore, 600mm stroke, front locker position, PT port threads, and 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 SAILF200X600 FAQ
At 0.5MPa it provides 15708N push and 15080N pull force. At 0.7MPa the push force is 21991N, reaching a maximum of 3204 kgf at 1.0MPa.
The lock is spring-applied and air-released, engaging statically to hold the rod at the extended stroke end when air is cut off. It unlocks automatically via an air signal or manually via a lever, but it does not clamp at mid-stroke.
