Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X160
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X160 is a genuine double-acting ISO 15552 profile cylinder with a Ø200mm 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 SAILF200X160
The AirTAC SAILF200X160 is a double-acting ISO 15552 profile cylinder equipped with a spring-applied, air-released mechanical lock in the front cover. Because the lock resides in the front end, it engages when the piston reaches the extended stroke end, securely holding the rod out without requiring live air pressure. In the 200 mm bore class, this actuator delivers a substantial 15708 N of push force at 0.5 MPa and reaches a maximum of 3204 kgf at 1.0 MPa.
The lock is a static holding device, not a dynamic brake for a moving rod. A notable design trait of this locker end is its shorter variable air cushion (28 mm), which handles end-of-stroke deceleration before the lock pins engage. The carbon steel rod provides robust side-load resistance, and the unit uses PT tapered port threads. For position sensing, an -S magnet would be required to use CMSE reed or DMSE electronic switches, though this configuration omits it.

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 SAILF200X160 Is Used
Heavy Lift Holding
Secures elevated platens in the extended position, preventing catastrophic drops if air pressure drops suddenly during a power loss.
Safety Gate Lock
Keeps heavy industrial safety gates firmly open and locked at the extended stroke end until the air-release port is actively pressurized.
Clamp and Hold
Maintains constant clamping pressure on large fabricated parts at the end of the stroke without consuming continuous compressed air.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X160 the Right Lock Cylinder?
Choose this 200 mm bore model when an application demands immense thrust alongside guaranteed load holding at the rod-out position. If 15708 N of push at 0.5 MPa exceeds your requirement, stepping down to a 160 mm bore yields 10053 N while saving space. Conversely, if you need to hold the load at the retracted rod-in position, select the SAILB variant instead. If the mechanism requires clamping at an arbitrary mid-stroke point rather than a stroke end, the BSAI clamp-lock cylinder is the correct choice.
When integrating this cylinder, adhere to strict valve selection guidelines: never use a fast-exhaust valve, and always utilize an independent-exhaust solenoid valve. Back-pressure on the locker side can inadvertently release the spring-applied lock. Furthermore, if human safety depends on the load remaining extended, install an independent mechanical safety measure as a backup. To replace this unit, match the 200 mm bore, 160 mm stroke, front locker position, PT port threads, and desired mounting accessory from the Basic, FA, FB, CA, CB, CR, LB, TC, FTC, TCM1, or TCM2 set.
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 SAILF200X160 FAQ
At 0.5 MPa, the 200 mm bore provides 15708 N of push force and 15080 N of pull force. At its maximum operating pressure of 1.0 MPa, it delivers a peak push force of 3204 kgf.
The lock is spring-applied and air-released, engaging only when the rod reaches the extended stroke end. It provides a static hold, not a dynamic brake. Unlocking occurs automatically by supplying air to the release port or manually via the release lever.
