Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X1000
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X1000 is a genuine double-acting ISO 15552 profile cylinder with a Ø200mm bore, 1000mm 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 SAILF200X1000
The AirTAC SAILF200X1000 is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released mechanical lock integrated into the front cover. This lock engages automatically when the piston reaches the extended stroke end, securely holding a 1000 mm rod extension without requiring continuous live air pressure. Delivering 15708 Newtons of push force at 0.5 MPa, it is built for heavy-duty load management. The standard carbon steel rod provides durable service in demanding industrial environments.
Because the lock mechanism occupies end-cover space, the variable air cushion at the locker end is 28 mm, which is shorter than the 50 mm cushion found on the non-locking end. The lock is a static holding device that engages only after the cylinder stops; it is not a dynamic brake for a moving rod. For power-loss safety, the lock releases automatically via air supply to the release port or manually via a lever. If human safety depends on the suspended load, an independent mechanical safety measure must supplement the lock.

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 (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 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 SAILF200X1000 Is Used
Vertical Lift Safety
Holds heavy elevated platforms securely at the extended stroke end during a sudden power loss, preventing gravity-driven collapses.
Heavy Gate Control
Maintains large industrial gates in the open position without consuming continuous air supply, releasing only when commanded by air pressure.
Press Clamping
Secures heavy workpieces at the end of the 1000 mm extension, ensuring the load remains fixed while pressure is vented from the main system.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X1000 the Right Lock Cylinder?
Choose this 200 mm bore cylinder when an application requires holding a massive load at the fully extended position, utilizing its 15708N thrust at 0.5 MPa. If your load only needs to be secured at the retracted rod-in position, select the SAILB variant instead. For applications requiring the load to be clamped and held at an arbitrary mid-stroke point rather than a stroke end, the BSAI clamp-lock cylinder is the correct choice. The SAILF lock provides a static hold, not a mid-stroke clamp.
This 1000 mm stroke exceeds the 1500 mm maximum standard stroke configuration limit for this bore, classifying it as a non-standard build. At this length, side-load forces are amplified; always use a dedicated external guide to prevent rod binding and premature seal wear. When specifying the pneumatic control, never use a fast-exhaust valve with a lock cylinder. Use an independent-exhaust solenoid valve, as back-pressure on the locker side can inadvertently release the lock. Replacement parts must match the 200 mm bore, 1000 mm stroke, front locker position, PT port threads, and standard mounting interface.
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 SAILF200X1000 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 Newtons of push force and 15080 Newtons of pull force. The maximum push force reaches 28274 Newtons at the 1.0 MPa pressure limit.
The lock is spring-applied and air-released, engaging statically at the extended stroke end to hold the load without live pressure. It unlocks automatically via air supply to the release port or manually via a lever. It does not clamp at arbitrary mid-stroke positions; use a BSAI cylinder for that functionality.
