About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X900
The AirTAC SAILF160X900 is a double-acting ISO 15552 profile cylinder featuring a built-in mechanical lock in the front cover. A spring-applied, air-released pin engages when the piston reaches the extended stroke end, securely holding a 900mm load without relying on continuous live air pressure. Delivering 14074N of push force at 0.7MPa, this carbon-rod unit is built for heavy vertical lifting tasks.
The lock is a static holding device, not a dynamic brake for a moving rod. Because the lock occupies end-cap space, the variable air cushion at the locker end is 28mm, noticeably shorter than the 50mm cushion on the rear end. For position feedback, adding a magnet allows the use of CMSE reed or DMSE electronic sensors.

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 SAILF160X900 Is Used
Extended Lift Holding
Secures heavy elevated platforms or doors at the full extended stroke end, preventing sudden drops during a compressed air or power loss event.
End-of-Stroke Clamp
Maintains maximum push-out force against a workpiece at the extended terminal, locking the load firmly without consuming pneumatic energy.
Vertical Load Safety
Provides a fail-safe hold for heavy vertical actuators, ensuring the extended load remains securely suspended until air is supplied to the release port.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X900 the Right Lock Cylinder?
Choose this 160mm bore when 100mm (5497N at 0.7MPa) lacks the push power for heavy lifting, but step up to 200mm if you need 21991N. Select this SAILF front-lock version when the machinery requires the load to be safely held at the extended rod-out position; choose SAILB if the retracted rod-in position must be secured. If your process requires clamping at an arbitrary mid-stroke point rather than the stroke terminal, select the BSAI clamp-lock cylinder instead.
This 900mm stroke exceeds typical handling lengths, so use a linear guide to prevent rod side-load damage. Remember the lock engages only after the cylinder stops. Avoid fast-exhaust valves, as back-pressure on the locker side can unintentionally release the lock; use an independent-exhaust solenoid valve. If human safety depends on the load staying up, add an independent mechanical safety measure. Replacement matches require 160mm bore, 900mm stroke, front lock, PT 3/4 port, and standard carbon steel 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 SAILF160X900 FAQ
At 0.7MPa operating pressure, the 160mm bore generates 14074N of push force and 9425N of pull force. The maximum operating pressure is 1.0MPa, yielding a maximum push force of 18095N.
The lock is spring-applied and air-released, engaging statically when the rod reaches the extended stroke end. It does not clamp mid-stroke. Unlocking occurs automatically by supplying air to the release port or manually via the lever. Never use a fast-exhaust valve, as back-pressure can release the lock.
