About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X800
The AirTAC SAILF160X800 is a double-acting ISO 15552 profile cylinder featuring a built-in mechanical lock housed in the front cover. Because this is a SAILF configuration, the spring-applied, air-released lock engages precisely when the piston reaches the extended stroke end, securely holding the rod out without relying on continuous live pressure. In this 160mm bore class, the cylinder generates a substantial 14074N of push force at 0.7 MPa, making it suitable for heavy-duty positioning tasks.
The lock is a static holding device, not a dynamic brake for a moving rod. To release the load, operators can supply air to the release port for automatic unlocking or use the manual override lever. The extruded aluminum barrel incorporates sensor grooves on both sides for CMSE reed or DMSE electronic switches, though this specific unit ships without a piston magnet. Additionally, the variable air cushion at the locker end is notably shorter than at the free end, measuring 28mm versus 50mm, a specific design accommodation for the locking mechanism.

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 SAILF160X800 Is Used
Heavy Lift Holding
Secures elevated machinery or heavy platens in the extended position, preventing accidental descent during a compressed air failure.
Safety Gate Lock
Keeps large industrial safety gates and access barriers firmly locked open at the end of stroke until the release air is actively supplied.
Press Clamping
Applies 14074N of clamping force at 0.7 MPa and maintains that static hold on the workpiece without consuming continuous air pressure.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X800 the Right Lock Cylinder?
Choose this 160mm bore when an application requires moving heavy loads up to 14074N at 0.7 MPa and safely holding them at the extended stroke end. If your force requirements are lower, stepping down to a 125mm bore yields 8590N at the same pressure. Conversely, if you need to secure the load at the retracted rod-in position, the SAILB160X800 is the correct variant. Should your machinery require locking at an arbitrary mid-stroke point rather than the stroke terminal, the BSAI clamp-lock cylinder is the appropriate choice instead of this end-of-stroke model.
When integrating this cylinder, be aware that the lock holds statically after the rod stops. Valve selection is critical: never use a fast-exhaust valve with a lock cylinder. You must use an independent or individual-exhaust solenoid valve, because back-pressure on the locker side can inadvertently release the lock. If human safety depends on the load remaining elevated, always add an independent mechanical safety measure. For this 800mm stroke, mounting must account for side loads; use a non-rotating guide or external load support to prevent rod binding. Replacement matches require the 160mm bore, 800mm stroke, front locker position, PT port threads, and compatible mounting hardware.
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 SAILF160X800 FAQ
At a 0.7 MPa operating pressure, this 160mm bore cylinder provides a push force of 14074N and a pull force of 9425N. The maximum allowable operating pressure is 1.0 MPa.
The lock is spring-applied and air-released, engaging statically only when the piston reaches the extended stroke end. It does not clamp at mid-stroke. Unlocking is achieved automatically by supplying release air or manually via the lever, and you must avoid fast-exhaust valves to prevent back-pressure from releasing the lock.
