About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X600S
The AirTAC SAILF160X600-S is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released mechanical lock housed in the front cover. This lock engages when the piston reaches the extended stroke end, securely holding the load without requiring continuous live air pressure. In the 160mm bore class, it delivers a robust 18095N of push force at 0.9 MPa, utilizing a 40mm carbon steel rod and 3/4 PT ports to handle heavy-duty positioning tasks.
Equipped with a magnet (-S), this model supports AirTAC DMSE electronic solid-state and CMSE reed sensors for precise end-position detection. The variable air cushion at the locker end is 28mm, intentionally shorter than the 50mm cushion at the free end to accommodate the locking mechanism. It operates at speeds of 30-500 mm/s, and unlocking is achieved automatically by supplying air to the release port or manually via the release 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 SAILF160X600S Is Used
Heavy Press Hold
Maintains 18095N of clamping force at the extended stroke end without continuous air supply, ensuring press operations remain locked during power loss.
Vertical Lift Safety
Secures elevated heavy loads in the rod-out position using the front mechanical lock, preventing sudden drops when system pressure is removed.
Pallet Stopper Gate
Acts as a robust stop gate that extends and locks into place to halt heavy pallet conveyance, requiring deliberate air release to retract.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X600S the Right Lock Cylinder?
Select this 160mm bore cylinder when an application requires holding a massive load securely at the fully extended position; if lower force is needed, the 125mm bore provides 11045N at 0.9 MPa. Choose the SAILF front-locker variant specifically when the rod-out position must be maintained during a power loss. If the application instead requires clamping at an arbitrary mid-stroke point, the BSAI clamp-lock cylinder is the correct choice, as the SAIL lock functions exclusively as a static hold at the stroke terminal.
For safe integration, avoid using fast-exhaust valves, as back-pressure on the locker side can inadvertently release the lock; instead, use an independent-exhaust solenoid valve. Because this model features a 600mm stroke, external guide rails should be installed to prevent excessive side-loading on the rod. When ordering a replacement, verify the 160mm bore, 600mm stroke, front locker position, 3/4 PT ports, and the -S magnet option. If human safety relies on the load staying extended, always add an independent mechanical safety measure.
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 SAILF160X600S FAQ
At 0.9 MPa, this 160mm bore cylinder generates 18095N of push force and 14074N of pull force. At 0.5 MPa, the push force is 10053N.
The lock is spring-applied and air-released, engaging only when the rod reaches the fully extended stroke end. It provides a static hold, not a dynamic brake, and is released automatically by supplying air to the release port or manually via a lever.
