Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X1000S
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X1000S is a genuine double-acting ISO 15552 profile cylinder with a Ø160mm bore, 1000mm 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 SAILF160X1000S
The AirTAC SAILF160X1000-S is a double-acting ISO 15552 profile cylinder equipped with a mechanical lock in the front cover, designed to hold the rod securely at the extended stroke end. A carbon steel rod provides robust load handling, while the integrated -S magnet enables precise position sensing using AirTAC CMSE reed or DMSE electronic solid-state switches. In the 160mm bore class, it generates 10053N of push force at 0.5 MPa and 14074N at 0.7 MPa.
This unit utilizes a spring-applied, air-released locking mechanism: removing the release air drives a lock pin into the rod, maintaining the load without consuming live pressure. You can unlock it automatically by supplying air to the release port, or manually via the release lever. Because the lock occupies the front cover, the variable air cushion on that locker end is shorter (28mm) compared to the 50mm cushion on the free end. Note this is a static holding lock that engages after the piston stops, not 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 SAILF160X1000S Is Used
Extended Lift Holding
Secures vertical loads in the raised, extended position during a power loss, preventing gravity-driven drops until air is safely restored.
Heavy Pallet Stop
Holds a heavy workpiece or pallet at the extended stroke end on a conveyor line, maintaining position without continuous air consumption.
Safety Gate Lock
Keeps large machine safety gates open and locked at the full extended position, requiring a deliberate air release signal to close.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X1000S the Right Lock Cylinder?
Choose this 160mm bore when an application demands high thrust, such as 14074N push at 0.7 MPa; if less force is needed, a 125mm bore provides 8590N push at 0.7 MPa. Select the SAILF configuration when the load must be held at the extended rod-out position, whereas SAILB holds 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 choice instead.
For this 1000mm stroke model, external guide rails are strongly recommended to prevent excessive side-loading on the rod. Remember that the lock holds statically at the extended end only. Avoid using fast-exhaust valves, as back-pressure on the locker side can unintentionally release the lock; always use an independent-exhaust solenoid valve. For human-safety critical lifting applications, add an independent mechanical safety measure beyond the pneumatic lock. Replacement parts must match the 160mm bore, 1000mm stroke, front locker position, PT tapered ports, and -S magnet specification.
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 SAILF160X1000S FAQ
At 0.5 MPa, the 160mm bore generates 10053N of push force and 9425N of pull force. At 0.7 MPa, the push force increases to 14074N.
The lock is spring-applied and air-released, holding the rod statically at the extended stroke end. It engages after the cylinder stops and is released by supplying air to the release port or using the manual lever. It does not clamp at mid-stroke.
