Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X200
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X200 is a genuine double-acting ISO 15552 profile cylinder with a Ø160mm bore, 200mm 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 SAILF160X200
The AirTAC SAILF160X200 is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, featuring a built-in mechanical lock housed in the front cover. A spring-applied, air-released lock engages when the piston reaches the extended stroke end, securing the rod-out position. Delivering a robust 14074N of push force at 0.7 MPa, this 160mm bore cylinder utilizes a 40mm carbon steel rod and a 3/4 PT port for heavy-duty performance.
This static holding lock engages only after the cylinder stops, meaning it is not a dynamic brake for a moving rod. The variable air cushion at the locker end is 28mm, intentionally shorter than the 50mm cushion on the free end. For position feedback, adding a magnet allows the use of CMSE reed or DMSE electronic sensors in the dual-side barrel groove.

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 (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 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 SAILF160X200 Is Used
Vertical Lift Hold
Secures an extended vertical load instantly on the rod-out stroke end if air supply drops, preventing gravity-driven falls.
Machine Safety Gate
Locks a heavy safety barrier in the open extended position during power loss, requiring release air to move.
Heavy Press Hold
Maintains outward clamping pressure on large parts without consuming continuous compressed air.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X200 the Right Lock Cylinder?
Choose this SAILF160X200 when an application requires holding a load at the extended rod-out position without maintaining live air pressure. If the project demands holding at the retracted end, the SAILB160X200 is the correct alternative. For loads that must be locked at an arbitrary mid-stroke point rather than a stroke end, select the BSAI clamp-lock cylinder instead.
The lock holds the load statically at the stroke terminal; 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 if human safety depends on the load remaining extended, add an independent safety measure. Replacement requires matching the 160mm bore, 200mm stroke, front lock position, 3/4 PT port, and the desired mounting style from the full ISO 15552 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 SAILF160X200 FAQ
The 160mm bore generates 14074N of push force at 0.7 MPa and 10053N at 0.5 MPa. The maximum operating pressure is 1.0 MPa.
The lock is spring-applied and air-released. It engages statically when the rod reaches the extended stroke end, holding the load without live pressure. Supplying air to the release port unlocks it automatically, or a manual lever can be used.
