About the Airtac BSAI Locking Clamp Cylinder BSAI100X700S
The AirTAC BSAI100X700-S is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released clamp-lock. It provides a static holding force of 5500 N, gripping the 25 mm carbon steel rod to secure loads at any position along the 700 mm stroke. The base extruded-aluminum barrel is dimensionally interchangeable per ISO 15552, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE solid-state sensors. Operating pressure is 0.15-0.7 MPa, delivering a practical maximum thrust of 5497 N at 0.7 MPa.
It is vital to distinguish holding force from thrust: the 5500 N clamp grip is entirely separate from the 5497 N pneumatic push force, meaning you must size the clamp against the static load, not the cylinder's thrust. Furthermore, the variable air cushions at both ends only decelerate the piston near stroke limits; the enclasp clamp is the true holding device. Unlocking requires a third G1/8 port and balanced pressure on both piston sides, or the rod may jump abruptly upon release.

How the Clamp-Lock Holds
static holding force (Ø100 mm)
A spring-applied gripper clamps the rod and holds the load at any position in the stroke — not just at the stroke end (that is a SAIL) — and it is bidirectional: it holds whether the rod was extending or retracting.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa (max) | 5498 N | — |
Push/pull as tabulated. Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (5500 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAI Locking Clamp Cylinder BSAI100X700S Is Used
Vertical Axis Drop Prevention
Holds a 5500 N vertical load securely at any intermediate height during power loss, preventing gravity-driven falls on lifting stages.
Mid-Stroke Machining Hold
Locks the 25 mm rod rigidly at a specific non-end position for precise milling or inspection without relying on end-of-stroke cushions.
Emergency Power-Loss Safety
Spring-applied clamping engages instantly upon air loss to freeze the payload in place, though an independent safety measure is required for human safety.
Is the Airtac BSAI Locking Clamp Cylinder BSAI100X700S the Right Clamp-Lock?
Choose this 100 mm bore model when a load demands high holding capacity that a 80 mm bore (3600 N holding, 3518 N thrust at 0.7 MPa) cannot secure, or step down to an 80 mm bore if 3600 N is sufficient. The BSAI clamp-lock surpasses a SAIL cylinder because it enclasps the rod anywhere along the travel, whereas SAIL only holds at stroke ends. If no mid-stroke holding is needed, a plain SAI cylinder suffices. For this 700 mm stroke, an external guide is recommended to prevent side-load wear on the 25 mm rod thread.
The clamp locks only after the rod has fully stopped; it cannot brake a moving load, so human-safety applications require an independent backup measure. To release safely, balance air pressure before supplying the G1/8 unlock port. This single-rod unit uses PT tapered ports (1/2 inch cylinder port), accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 mounts, and includes the -S magnet for CMSE/DMSE sensing.
Quick checklist
- ✓ Hold needed at any position?
- ✓ Or stroke-end only → use SAIL
- ✓ Holding force ≥ your load
- ✓ Balanced-pressure unlock circuit
- ✓ Extra safety measure for people
Airtac BSAI Locking Clamp Cylinder BSAI100X700S FAQ
The spring-applied, air-released clamp provides a static holding force of 5500 N. It grips the rod bidirectionally at any position, but only engages after the cylinder has stopped moving; it is not a braking device for a moving rod.
The clamp uses a third G1/8 enclasp port and requires balanced air pressure on both sides of the piston before unlocking. If pressures are unbalanced, the rod can move abruptly upon release, making external safety measures necessary for critical loads.
