About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X150
The AirTAC SAILF160X150 is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released mechanical lock housed in the front cover. Because the lock resides in the front end, it engages when the piston reaches the extended stroke end, firmly holding the rod out without relying on live air pressure. In this 160 mm bore class, it delivers a substantial push force of 10053 N at 0.5 MPa and a pull force of 9425 N.
This unit utilizes a carbon steel rod and PT tapered port threads. The integrated lock is designed for static holding after the cylinder stops, rather than acting as a dynamic brake for a moving rod. To accommodate the locking hardware, the variable air cushion at the locker end is 28 mm, noticeably shorter than the 50 mm cushion on the free end. The lock releases automatically via air supply or manually via a lever.

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 SAILF160X150 Is Used
Extended Lift Holding
Secures vertical lifts in the extended position during power loss, preventing heavy loads from dropping when air pressure is cut.
Press Safety Lock
Holds a heavy press ram safely at the extended stroke end after the motion has stopped, ensuring the tooling stays closed without live pressure.
Gate Actuation
Drives and statically locks large industrial gates in the open position, utilizing the robust 10053 N force capacity to handle substantial resistance.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X150 the Right Lock Cylinder?
Select this 160 mm bore when an application demands heavy load holding at the extended position; if you need less force, stepping down to a 125 mm bore yields 6136 N of push at 0.5 MPa. Choose this SAILF configuration specifically to secure the rod-out end. If your requirement is to hold a load mid-stroke, you must select a BSAI clamp-lock cylinder instead, as the SAIL lock only engages at the stroke terminal.
For safe operation, do not use a fast-exhaust valve with this lock cylinder; an independent-exhaust solenoid valve is required, as back-pressure on the locker side can inadvertently release the lock. If human safety depends on the load staying extended, add an independent safety measure. Replacement matches require the 160 mm bore, 150 mm stroke, front locker position, 3/4 PT port, and your 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 SAILF160X150 FAQ
At 0.5 MPa operating pressure, the 160 mm bore provides a push force of 10053 N and a pull force of 9425 N. At 0.7 MPa, the push force increases to 14074 N.
The lock is spring-applied and air-released, located in the front cover to hold the rod only at the extended stroke end. It engages statically after the cylinder stops and is not a mid-stroke clamp or dynamic brake; unlocking is achieved automatically via air release or manually via a lever.
