About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X700S
The AirTAC SAILF160X700-S is a double-acting ISO 15552 profile cylinder equipped with a spring-applied, air-released mechanical lock housed in the front cover. Because the lock engages when the piston reaches the extended stroke end, it securely holds the rod-out position without requiring continuous live air pressure. Delivering a robust 14074 N of push force at 0.7 MPa, this carbon-rod unit is built for heavy-duty load management.
This model includes a magnetic piston (-S) for precise position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors. The lock mechanism features a shorter 28 mm air cushion at the locker end compared to the 50 mm cushion on the free end, ensuring compact deceleration. Unlocking is achieved automatically by supplying air to the release port or manually via the integrated 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 SAILF160X700S Is Used
Extended Lift Holding
Maintains elevated heavy loads at the full rod-out position automatically upon air pressure loss, preventing sudden drops in vertical lifting presses.
Power-Out Safety Gate
Secures heavy safety barriers and machine gates in the open, extended position during power outages until release air is deliberately restored.
Heavy Clamp Retention
Holds large fabricated components firmly at the extended stroke end during machining cycles, eliminating the need for continuous pneumatic pressure.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X700S the Right Lock Cylinder?
Choose this 160 mm bore when an application demands high thrust that exceeds the 8590 N push force at 0.5 MPa of the smaller 125 mm variant. Select the SAILF configuration when the load must be held securely at the extended rod-out position; conversely, a SAILB version holds the retracted position. If your process requires clamping at an arbitrary mid-stroke point rather than a terminal stroke end, the BSAI clamp-lock cylinder is the correct choice instead of this SAIL model.
The integrated lock provides a static hold that engages only after the cylinder stops; it is not a dynamic brake for a moving rod. To maintain lock integrity, never use a fast-exhaust valve, as back-pressure on the locker side can inadvertently release the mechanism—always utilize an independent-exhaust solenoid valve. For any safety-critical lifting application, an independent mechanical safety measure must supplement the lock. With a 700 mm stroke, external guide rails are highly recommended to manage side loads and prevent rod binding. Replacement specifications require a 160 mm bore, 700 mm stroke, front locker, PT 3/4 port, and a magnetic piston.
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 SAILF160X700S FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At 0.7 MPa, the push force increases to 14074 N, and it reaches 18095 N at 0.9 MPa.
The lock is spring-applied and air-released, engaging only when the piston reaches the extended stroke end. It provides a static hold, not a dynamic brake. It unlocks automatically via air supply to the release port or manually via a lever, but back-pressure from fast-exhaust valves must be avoided to prevent accidental release.
