Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X700S
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X700S is a genuine double-acting ISO 15552 profile cylinder with a Ø200mm 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 SAILF200X700S
The AirTAC SAILF200X700-S is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released mechanical lock housed in the front cover. This lock engages when the piston reaches the extended stroke end, securely holding the load without requiring live air pressure. Delivering 15708N of push force and 15080N of pull force at 0.5 MPa, this carbon-rod unit is equipped with a magnetic piston (-S) for compatibility with CMSE reed and DMSE solid-state sensors.
The front locker end features a 28mm variable air cushion, which is shorter than the 50mm cushion on the rear free end. Remember that the lock is a static holding device, not a dynamic brake; it engages only after the rod has stopped. If your application requires clamping at an arbitrary mid-stroke position rather than the extended end, the AirTAC BSAI clamp-lock cylinder is the correct choice.

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 SAILF200X700S Is Used
Overhead Lift Safety
Secures heavy vertical lifts at the extended top position. The spring-applied lock prevents sudden drops during power loss, providing a reliable static hold.
Heavy Gate Holding
Maintains large industrial gates or doors in the open, rod-out position without consuming continuous air supply, unlocking automatically via air release.
Press Clamping
Drives a 15708N press action and locks the workpiece at the extended stroke end. The shorter 28mm front cushion decelerates the load before the lock engages.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X700S the Right Lock Cylinder?
Choose this 200mm bore cylinder when an application demands massive thrust and guaranteed load holding at the rod-out position. If 15708N of push at 0.5 MPa is excessive, stepping down to a 160mm bore yields 10053N while saving space. Conversely, if you need to hold the load at the retracted stroke end instead, you must select the SAILB variant. The lock operates at 30-500 mm/s; 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, and add an independent safety measure if human safety depends on the load staying up.
When replacing this unit, verify the 700mm stroke, front locker position, 3/4 PT port threads, and the -S magnet. Because the stroke is 700mm, ensure you use a suitable mounting accessory from the Basic, FA, FB, CA, CB, CR, LB, TC, FTC, TCM1, or TCM2 set to prevent excessive side-loading on the extended rod.
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 SAILF200X700S FAQ
At 0.5 MPa, the push force is 15708N and the pull force is 15080N. At the maximum operating pressure of 1.0 MPa, the push force reaches 3204 kgf.
The lock is spring-applied and air-released, engaging only at the extended stroke end after the rod stops. It provides a static hold, not a dynamic brake. You can unlock it automatically by supplying air to the release port or by using the manual release lever.
