Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X100S
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X100S is a genuine double-acting ISO 15552 profile cylinder with a Ø160mm bore, 100mm 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 SAILF160X100S
The AirTAC SAILF160X100-S is a double-acting ISO 15552 profile cylinder equipped with a mechanical lock in the front cover, engineered to secure the rod at the fully extended stroke end. It delivers substantial thrust, generating 14074N of push force and 9425N of pull force at 0.7 MPa. A carbon steel piston rod provides robust resistance against bending under heavy loads, and the integrated -S magnet supports position sensing via CMSE reed or DMSE electronic solid-state switches.
This unit utilizes a spring-applied, air-released locking mechanism: removing the release air drives a lock pin into the rod, holding the load statically without requiring live pressure. To disengage, simply supply air to the release port for automatic unlocking or use the manual release lever. Note that the variable air cushion at the locker end is 28 mm, intentionally shorter than the 50 mm cushion on the free end to accommodate the locking hardware.

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 SAILF160X100S Is Used
Vertical Lift Hold
Secures elevated heavy platforms at the extended stroke end, preventing sudden drops if air pressure is lost during operation.
Pallet Stop Gate
Holds a heavy pallet firmly in position at the end of the extension stroke without consuming continuous pneumatic energy.
Safety Guard Lock
Keeps heavy machine safety doors locked open at the extended terminal position until the air-release system is deliberately activated.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X100S the Right Lock Cylinder?
Choose this 160 mm bore when an application demands higher force than a 125 mm bore, which provides 8590N push at 0.5 MPa, but does not require the extreme output of a 200 mm unit. Select the SAILF configuration specifically when the load must be held safely at the extended rod-out position; conversely, a SAILB variant secures the retracted position. If your process requires clamping at an arbitrary mid-stroke point rather than a stroke-end hold, the BSAI clamp-lock cylinder is the correct choice.
The lock engages only after the cylinder has stopped, functioning as a static holding device rather than a dynamic brake for a moving rod. Avoid using fast-exhaust valves with this cylinder; back-pressure on the locker side can inadvertently release the lock, so an independent-exhaust solenoid valve is required. For any safety-critical lifting application where human safety depends on the load staying up, always add an independent secondary safety measure. Replacement specifications must match the 160 mm bore, 100 mm stroke, front locker position, PT tapered port threads, and the -S magnet option.
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 SAILF160X100S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074N and a pull force of 9425N. The maximum push force reaches 18095N at 0.9 MPa.
The lock is spring-applied and air-released, holding the rod statically at the extended stroke end. It engages automatically when air is cut and releases when air is supplied to the release port, with a manual override available. It is not a mid-stroke clamp or a dynamic brake.
