About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X75
The AirTAC SAILF160X75 is a double-acting ISO 15552 profile cylinder featuring a built-in mechanical lock in the front cover. It delivers massive thrust, providing 14074N push force at 0.7 MPa, making it ideal for heavy-duty handling. The lock is spring-applied and air-released, meaning it engages automatically to hold the rod securely at the extended stroke-end when release air is cut, ensuring true power-loss safety. You can unlock it by resupplying release air or using the manual release lever.
This model uses a 40mm carbon steel rod with an M36x2 thread, offering high side-load resistance for heavy mounts. The variable air cushion at the locker end is 28mm, notably shorter than the 50mm cushion on the free end, ensuring compact deceleration without interfering with the lock engagement. The lock provides a static hold after the cylinder stops; it is not a dynamic brake for moving rods.

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 SAILF160X75 Is Used
Heavy Press Hold
Maintains high clamping force on large metal fabrications at the extended stroke end during power loss, ensuring workpieces stay fixed without live air.
Overhead Lift Safety
Secures lifted heavy payloads in the extended position instantly if air pressure drops, preventing sudden falls until release air is resupplied.
Gate Barrier Lock
Holds heavy industrial gates open at the full stroke-end position, using the mechanical lock to resist wind or impact loads without constant pneumatic pressure.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X75 the Right Lock Cylinder?
Choose this SAILF160X75 when a process requires holding a heavy load at the fully extended rod-out position without relying on live air pressure. If your application needs slightly less force, stepping down to a 125mm bore yields 8590N push at 0.7 MPa. Conversely, if you need to hold the load in the retracted position, select the SAILB variant instead. For applications requiring the load to be clamped at an arbitrary mid-stroke point rather than the stroke end, select the BSAI clamp-lock cylinder.
Because the lock is spring-applied, pneumatic back-pressure on the locker side can unintentionally release the lock. Do not use a fast-exhaust valve with this cylinder; instead, use an independent-exhaust solenoid valve to ensure safe venting. If human safety depends on the load staying extended, add an independent mechanical safety measure as well. Replacement specifications: 160mm bore, 75mm stroke, front locker, PT port threads, and standard carbon steel rod.
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 SAILF160X75 FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides 14074N of push force and 9425N of pull force. It can achieve a maximum push force of 18095N at 0.9 MPa.
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 unlocked by supplying release air or using the manual lever. It does not clamp at mid-stroke; for arbitrary position locking, use the BSAI series.
