About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X150S
The AirTAC SAILF160X150-S is a double-acting ISO 15552 profile cylinder equipped with a mechanical lock in the front cover, engineered to hold the rod securely at the extended stroke end. Built with a carbon steel rod and a magnetic piston for position sensing, it provides a robust push force of 14074N and a pull force of 9425N at 0.7 MPa. The integrated lock is spring-applied and air-released, meaning it engages automatically upon loss of release air to maintain the load safely without consuming live pressure.
Because the lock is housed in the front end, the variable air cushion on that side is notably shorter at 28 mm compared to the 50 mm cushion on the free end. This model includes the -S magnet option, making it fully compatible with AirTAC CMSE reed and DMSE electronic solid-state sensors for precise end-of-stroke detection. The lock engages statically after the piston stops, rather than acting as a dynamic brake for a moving rod.

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 SAILF160X150S Is Used
Heavy Press Hold
Maintains high-tonnage clamping force at the extended stroke end during power loss, ensuring the press stays safely closed without relying on continuous air supply.
Vertical Lift Safety
Secures elevated loads in the extended position. The spring-applied lock engages instantly if air pressure drops, preventing sudden descent of heavy lifting platforms.
Gate Actuation
Holds large industrial gates or doors firmly in the open, extended position. The robust 40 mm carbon steel rod withstands demanding outdoor or heavy-duty mechanical stress.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X150S the Right Lock Cylinder?
Select this 160 mm bore cylinder when an application demands heavy load holding at the fully extended position; if less force is required, the 125 mm bore offers 8590N of push force at 0.5 MPa. Choose the SAILF configuration specifically when the extended rod-out position is the safety-critical state, whereas a SAILB variant would hold the retracted position. If your process requires clamping at an arbitrary mid-stroke point rather than the stroke terminal, the BSAI clamp-lock cylinder is the correct alternative.
For safe operation, never use a fast-exhaust valve with this lock cylinder; always utilize an independent-exhaust solenoid valve, as back-pressure on the locker side can inadvertently release the spring-applied lock. Furthermore, if human safety depends on the load remaining extended, implement an independent mechanical safety measure as a backup. Replacement specifications require a 160 mm bore, 150 mm stroke, front locker position, PT tapered port threads, and the -S magnet option.
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 SAILF160X150S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074N and a pull force of 9425N. The maximum push force reaches 18095N at 0.9 MPa.
The lock is spring-applied and air-released, holding the rod statically only at the extended stroke end in the front cover. It unlocks automatically via air supply to the release port or manually via a lever, but it cannot clamp the rod at a mid-stroke position.
