About the Airtac SAILF Front Locking Pneumatic Cylinder SAILF63X1000
The AirTAC SAILF63X1000 is a double-acting ISO 15552 profile cylinder featuring a built-in mechanical lock in the front cover. A spring-applied, air-released mechanism holds the rod securely at the fully extended stroke end, maintaining the load without live air pressure. At 0.7 MPa it provides 2182 N of push force and 1402 N of pull force.
This 63 mm bore unit operates at 30-800 mm/s and uses a 3/8 port. The variable air cushion at the locker end is 21 mm, intentionally shorter than the 30 mm cushion on the rear cover. For position sensing, you can add a magnet to use CMSE reed or DMSE solid-state sensors.

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 SAILF63X1000 Is Used
Extended Load Hold
Maintains vertical loads securely at the fully extended stroke end, preventing drops during power loss.
Flow Control Stops
Locks a diverter or stopper block in the extended out position to halt heavy product flow on a line.
Safety Gate Lock
Keeps a protective machine gate open and rigidly held at the extended end without continuous air supply.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF63X1000 the Right Lock Cylinder?
Choose this 1000 mm stroke model when you need to secure a load at the extended position. If your application requires holding at the retracted end, select the SAILB variant instead, or step up to the 80 mm bore for 3518 N of push force at 0.7 MPa. Because this is a 1000 mm stroke, use a guide rail to prevent side-load damage to the 20 mm carbon steel rod.
The lock engages statically after the cylinder stops at the stroke terminal; it is not a dynamic brake for a moving rod. If you need to clamp at an arbitrary mid-stroke position, use the BSAI clamp-lock cylinder instead. Avoid fast-exhaust valves, as back-pressure on the locker side can accidentally release the lock; use an independent-exhaust solenoid valve. Add an independent safety measure if human safety depends on the load staying up.
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 SAILF63X1000 FAQ
