About the Airtac SAILB Rear Lock Cylinder SAILB100X160S
The AirTAC SAILB100X160-S is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released mechanical lock housed in the back cover. It securely holds the rod at the retracted stroke end, delivering 3927N of push force at 0.5MPa. The integrated lock engages automatically when release air is cut, ensuring power-loss safety without requiring live pressure.
This bore 100 unit includes a magnetic piston (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. It features a carbon steel rod and PT tapered ports. Note the variable air cushion at the locker end is shorter (24mm) than the free end (36mm); this cushion only decelerates the piston near stroke end, while the lock provides the actual static holding force.

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 retracted (rod-in) 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 back-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 SAILB Rear Lock Cylinder SAILB100X160S Is Used
Vertical Power-Loss Safety
Holds heavy vertical loads safely in the retracted position when air supply drops, preventing sudden crashes.
Retracted Clamp and Hold
Maintains solid clamping pressure at the stroke end without consuming continuous live air pressure.
Lift and Gate Security
Secures lifted gates and guards in the closed position, offering reliable mechanical locking for operator safety.
Is the Airtac SAILB Rear Lock Cylinder SAILB100X160S the Right Lock Cylinder?
Choose this model when a load must be safely held at the retracted position upon power loss. If your application requires slightly less force, the bore 80 offers 2513N at 0.5MPa; if more is needed, the bore 125 provides 6136N. Select SAILB for back-cover retracted holding, or SAILF if the extended rod-out position must be held. If you need to clamp the rod at an arbitrary mid-stroke point rather than a stroke end, use the BSAI clamp-lock cylinder instead.
This is a static holding lock that engages after the cylinder stops, not a dynamic brake for a moving rod. Valve selection is critical: avoid fast-exhaust valves, as back-pressure on the locker side can unintentionally release the lock; use an independent-exhaust solenoid valve. For human-safety dependent loads, add an independent safety measure. Replacement matches require bore 100, stroke 160, back locker, PT port, and the -S magnet.
Quick checklist
- ✓ Hold needed at the retracted (rod-in) end?
- ✓ Or lock anywhere → use BSAI
- ✓ Independent-exhaust valve fitted
- ✓ Port/thread type (PT/G)
- ✓ Extra safety measure for people
Airtac SAILB Rear Lock Cylinder SAILB100X160S FAQ
At 0.5MPa, it provides 3927N of push force and 3681N of pull force. At 0.7MPa, the push force increases to 5497N.
The lock is spring-applied and air-released, located in the back cover to hold the rod only at the retracted stroke end. It unlocks automatically via air supply or manually via a lever. It is a static hold, not a mid-stroke clamp or dynamic brake.
