About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF63X160
The AirTAC SAILF63X160 is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released mechanical lock housed in the front cover. This lock engages automatically when the piston reaches the extended stroke end, securely holding the rod-out position without requiring continuous live air pressure. In the 63 mm bore class, it generates 1559 N of push thrust and 1402 N of pull thrust at 0.5 MPa, utilizing a 20 mm carbon steel rod.
Because the lock occupies the front cover, the variable air cushion on that locker end is shortened to 21 mm, compared to the 30 mm cushion on the free back end. The lock releases automatically by supplying air to the release port, or manually via the lever. For position sensing, adding the -S magnet option allows the use of AirTAC CMSE reed or DMSE electronic solid-state sensors in the dual-side barrel grooves.

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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 SAILF63X160 Is Used
Extended Load Holding
Maintains vertical loads securely at the extended stroke end during power loss, preventing sudden drops without needing continuous air pressure.
Flow Control Diverter
Holds a diverter arm in the rod-out position to route packages on a conveyor, ensuring the mechanism remains rigidly fixed even if air supply fluctuates.
Safety Gate Barrier
Keeps a protective machine gate extended and locked open during maintenance, requiring an intentional air release signal to retract.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF63X160 the Right Lock Cylinder?
Select this 63 mm bore cylinder when an application requires safely holding a load at the fully extended rod-out position. If your process requires clamping at an arbitrary mid-stroke point rather than the terminal end, the AirTAC BSAI clamp-lock cylinder is the correct choice instead. To safely release the lock, avoid using fast-exhaust valves; an independent-exhaust solenoid valve is required, as back-pressure on the locker side can unintentionally disengage the lock pin.
When verifying your replacement match, confirm the 160 mm stroke, front locker position, 3/8 PT port threads, and your required mounting style from the ISO 15552 set (Basic, FA, FB, CA, CB, CR, LB, TC, FTC, TCM1, TCM2). If human safety depends on the load staying extended, always add an independent mechanical safety measure beyond this static holding lock.
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 SAILF63X160 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
The lock is spring-applied and air-released, engaging only when the rod reaches the fully extended stroke end. It provides a static hold after the cylinder stops, not a mid-stroke clamp or dynamic brake. It unlocks automatically via air pressure or manually via a lever.
