Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X600S
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X600S is a genuine double-acting ISO 15552 profile cylinder with a Ø200mm bore, 600mm 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 SAILF200X600S
The AirTAC SAILF200X600-S is a double-acting ISO 15552 profile cylinder equipped with a built-in mechanical lock in the front cover. Because the lock is spring-applied and air-released, cutting the release air drives a lock pin into the rod to securely hold the load at the extended stroke end without requiring live pressure. Supplying air to the release port unlocks it automatically, or you can use the manual release lever. With a 200mm bore, it generates 15708N push and 15080N pull force at 0.5 MPa, peaking at 3204 kgf at 1.0 MPa.
This model includes a magnet (-S) for position sensing with AirTAC CMSE reed or DMSE solid-state switches. The extruded aluminum barrel features sensor grooves on both sides. Note that the variable air cushion at the locker end is shorter (28mm) than at the free end (50mm) to accommodate the locking mechanism. The standard carbon steel rod handles heavy loads, and PT tapered threads are used for the 3/4 inch ports.

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 SAILF200X600S Is Used
Vertical Lift Safety
Holds a heavy lifted load securely in the extended position instantly upon air pressure loss, preventing sudden drops on heavy machinery.
Extended Clamp Hold
Maintains maximum clamping force at the extended stroke end without consuming continuous compressed air, saving energy during long hold cycles.
Gate and Guard Positioning
Keeps heavy safety gates or machine guards fully extended and locked open during maintenance until the release air is actively supplied.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF200X600S the Right Lock Cylinder?
Choose this 200mm bore if your application requires extreme force (15708N push at 0.5 MPa) and a fail-safe hold at the extended stroke end. If you need less force, stepping down to a 160mm bore yields 10053N push at 0.5 MPa. Select this SAILF model when the load must be held extended; choose SAILB if the load must be held retracted. If your application requires locking at an arbitrary mid-stroke position rather than the stroke end, use the BSAI clamp-lock cylinder instead.
The SAIL lock is a static holding device that engages after the piston reaches the extended terminal, not a dynamic brake for a moving rod. Valve selection is critical: never use a fast-exhaust valve with this lock cylinder, and use an independent-exhaust solenoid valve, as back-pressure on the locker side can unintentionally release the lock. If human safety depends on the load staying extended, add an independent safety measure. For this 600mm stroke, use appropriate mounting guides to manage side loads and prevent rod binding. Replacement matches require 200mm bore, 600mm stroke, front locker position, PT port, and the -S magnet.
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 SAILF200X600S FAQ
At 0.5 MPa operating pressure, the 200mm bore provides 15708N of push force and 15080N of pull force. At the maximum 1.0 MPa pressure, it delivers a maximum push force equivalent to 3204 kgf.
The lock is spring-applied and air-released, engaging only when the piston reaches the extended stroke end to hold the load statically. It unlocks automatically when release air is supplied to the port, or manually via the release lever. It does not clamp at mid-stroke.
