Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X100
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X100 is a genuine double-acting ISO 15552 profile cylinder with a Ø100mm 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 SAILF100X100
The AirTAC SAILF100X100 is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released mechanical lock built into the front cover. This mechanism engages automatically when the piston reaches the extended stroke end, holding the load securely without requiring continuous live air pressure. It delivers a robust 5497N push force at 0.7 MPa, matching standard SAI thrust capabilities.
The front locker end features a variable air cushion of 24 mm, which is intentionally shorter than the 36 mm cushion on the free end to accommodate the locking hardware. The extruded aluminum barrel includes dual sensor grooves, and the standard carbon steel rod uses a PT tapered port thread. The lock releases automatically via air supply or manually via a 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SAILF100X100 Is Used
Extended Lift Hold
Maintains vertical loads in the raised extended position during power loss, preventing sudden drops.
End-Stroke Clamping
Secures a workpiece firmly at the full rod-out position without consuming continuous air pressure.
Gate Safety Hold
Keeps heavy safety gates open at the extended stroke end until an air signal releases the lock.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X100 the Right Lock Cylinder?
Choose this 100 mm bore when an application requires 5497N of push force at 0.7 MPa and must hold a load securely at the extended stroke end. If the load must be held mid-stroke rather than at the terminal position, select the BSAI clamp-lock cylinder instead. To step down force requirements, an 80 mm bore provides 3518N push at 0.7 MPa.
Ensure the system uses an independent-exhaust solenoid valve, as fast-exhaust valves can create back-pressure on the locker side that inadvertently releases the lock. This is a static holding lock that engages after the cylinder stops, not a dynamic brake. For human-safety critical suspended loads, always add an independent mechanical safety measure. Replacement matches require 100 mm bore, 100 mm stroke, front locker position, PT port, and standard mounting options.
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 SAILF100X100 FAQ
At 0.7 MPa, the push force is 5497N and the pull force is 3681N. The maximum push force is 7068N at 0.9 MPa.
The lock is spring-applied and air-released, engaging only when the piston reaches the extended stroke end. It provides a static hold after the rod stops, not a mid-stroke clamp. Unlocking occurs automatically via air supply or by using the manual release lever.
