Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X1000S
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X1000S 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 SAILF200X1000S
The AirTAC SAILF200X1000-S is a double-acting ISO 15552 profile cylinder equipped with 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 load without requiring continuous live air pressure. In the 200mm bore class, it generates a push force of 15708N and a pull force of 15080N at 0.5MPa, making it suited for massive vertical lifting tasks. The integrated magnet allows seamless operation with CMSE reed and DMSE solid-state sensors for precise end-position verification.
A critical mechanical feature is the variable air cushion at the locker end, which is shorter (28mm) than the free end cushion (50mm) to accommodate the locking mechanism. The lock itself is a static holding device, meaning it secures the rod only after the cylinder has stopped moving, rather than acting as a dynamic brake mid-stroke. For unlocking, operators can either supply air to the release port for automatic operation or use the manual release lever during maintenance.

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 SAILF200X1000S Is Used
Heavy Vertical Lift Holding
Secures massive lifted structures at the fully extended 1000mm stroke end, preventing sudden drops if main air supply pressure is lost during operation.
Press Clamp Securement
Maintains a rigid, extended clamping force on large fabricated components during power loss, ensuring the workpiece stays fixed until pressure is restored.
Safety Gate Locking
Acts as a fail-safe lock for heavy industrial safety gates or blast doors, holding the extended position securely without relying on continuous pneumatic energy.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X1000S the Right Lock Cylinder?
Select this 200mm bore model when an application requires holding extremely heavy loads at the extended stroke end, such as raising a 1000mm stroke platform. If the application demands holding the load at the retracted position instead, the SAILB200X1000-S is the correct alternative. Conversely, if the mechanism requires clamping at an arbitrary mid-stroke position rather than the stroke terminal, the BSAI clamp-lock cylinder should be specified instead of this SAIL series.
When configuring this model, verify that the 3/4 PT tapered ports and carbon steel rod meet your pneumatic circuit specifications. Because the 1000mm stroke is substantial, always use an independent guide rail to prevent excessive side loads from damaging the rod seals. Furthermore, avoid using a fast-exhaust valve on the locker side, as back-pressure can unintentionally release the lock; an individual-exhaust solenoid valve is required. If human safety depends on the load remaining extended, always add an independent mechanical safety measure alongside the cylinder 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 SAILF200X1000S FAQ
At a standard operating pressure of 0.5MPa, this 200mm bore cylinder provides a push force of 15708N and a pull force of 15080N. At the maximum rated pressure of 1.0MPa, it delivers a maximum push force of approximately 3204 kgf.
The lock is spring-applied and air-released, located in the front cover to hold the rod securely at the extended stroke end. It engages as a static hold after the cylinder stops moving and is not a dynamic brake; to unlock it, you supply air to the release port or use the manual override lever.
