Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X75S
The AirTAC Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X75S is a genuine double-acting ISO 15552 profile cylinder with a Ø100mm bore, 75mm 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 SAILF100X75S
The AirTAC SAILF100X75-S is a double-acting ISO 15552 profile cylinder equipped with a spring-applied, air-released mechanical lock in the front cover. This mechanism engages when the piston reaches the extended stroke end, securely holding the rod-out position without requiring continuous live air pressure. In the 100mm bore class, it generates 5497N of push force and 3681N of pull force at 0.7 MPa.
Because this unit includes the -S magnet option, it supports direct mounting of AirTAC CMSE reed and DMSE electronic solid-state sensors along the dual extruded barrel grooves. The variable air cushion at the lock end is specifically machined shorter (24mm versus 36mm on the free end) to physically accommodate the locking hardware. The standard carbon steel rod provides durable resistance to side loads, and the 1/2 inch PT port ensures high flow capacity for rapid cycling.

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 SAILF100X75S Is Used
Extended Load Holding
Secures heavy vertical loads in the rod-out position during power loss, preventing gravity-driven drops on lifting platforms.
Safety Gate Locking
Maintains a positive mechanical lock on extended safety gates and barriers without consuming compressed air.
Clamp and Hold
Delivers 5497N of push force at 0.7 MPa to extend and firmly hold heavy workpieces at the end of the machining cycle.
Is the Airtac SAILF Front Locking Pneumatic Cylinder SAILF100X75S the Right Lock Cylinder?
Select this 100mm bore when an application demands substantial end-of-stroke holding power, such as lifting heavy gates. If your thrust requirements are lower, stepping down to a 63mm bore yields 2182N push at 0.7 MPa, whereas moving up to a 125mm bore provides 8590N. Choose this SAILF configuration to secure the extended rod-out position; if you need to hold the retracted position instead, select a SAILB model. For applications requiring the load to be clamped at an arbitrary mid-stroke point rather than the stroke terminal, the BSAI clamp-lock cylinder is the correct choice.
Remember that this lock is a static holding device that engages after the cylinder stops, not a dynamic brake for a moving rod. Valve selection is critical: never use a fast-exhaust valve with this locker side, as back-pressure can unintentionally release the pin. Always utilize an independent-exhaust solenoid valve to manage the release air safely. If human safety depends on the load remaining elevated, implement an independent mechanical safety measure as a backup. Replacement units must match the 100mm bore, 75mm stroke, front locker position, 1/2 inch PT port, and -S magnet specification.
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 SAILF100X75S FAQ
At 0.7 MPa operating pressure, this 100mm bore cylinder generates 5497N of push force and 3681N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 7068N.
The lock is spring-applied and air-released, engaging only when the piston reaches the extended stroke end. It provides a static hold without live pressure; supplying air to the release port or using the manual lever unlocks the rod.
