Airtac BSAID Clamp Cylinder BSAID100X75S
The AirTAC Airtac BSAID Clamp Cylinder BSAID100X75S is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 75mm stroke and a spring-applied, air-released clamp-lock that holds the rod at ANY position along its travel — with a static holding force of 5500 N.

About the Airtac BSAID Clamp Cylinder BSAID100X75S
The AirTAC BSAID100X75-S is a double-acting ISO 15552 profile cylinder featuring a double-rod configuration and a built-in clamp-lock mechanism. A spring-applied, air-released gripper secures the piston rod at any position along its 75 mm travel, delivering a static holding force of 5500 N. Because it is a double-rod design, the thrust is equal in both directions at 3681 N (0.5 MPa), and the second rod allows you to mount a workpiece on one end and a guide or position flag on the other for dual-side anti-rotation.
It is vital to distinguish this 5500 N static holding force from the 3681 N cylinder thrust; size the clamp against the static load, not the drive force. The clamp operates via a third G1/8 enclasp port, separate from the two 1/2 cylinder ports. Remember that the variable air cushions only decelerate the piston near stroke ends, while the clamp is the actual load-holding device. The clamp locks only after the rod has stopped, and it requires balanced air pressure (0.15-0.7 MPa) to unlock safely.

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 | — |
Equal force both directions (double rod). 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 BSAID Clamp Cylinder BSAID100X75S Is Used
Vertical Load Holding
Secures a heavy vertical payload at any intermediate height during power loss, using the 5500 N clamp to prevent drift without relying on live air pressure.
Machining Position Lock
Holds a dual-sided workpiece rigidly in place for machining or inspection, using the second rod for an external guide to resist side loads.
Emergency Safety Stop
Acts as a static holding brake once the rod has stopped moving, providing a reliable intermediate-position lock for elevated safety requirements.
Is the Airtac BSAID Clamp Cylinder BSAID100X75S the Right Clamp-Lock?
Choose this double-rod model when a process requires equal push/pull forces and multi-axis mounting. If you do not need a second rod, a single-rod BSAI100X75-S provides the same 5500 N hold. Step down to an 80 mm bore if your load is lighter, offering 2268 N thrust and a 3600 N hold. Select BSAI/BSAID over a SAIL cylinder when you must lock at any intermediate stroke position, not just at the end. The clamp locks only after the cylinder stops, so human-safety applications need an independent external brake. This unit includes a -S magnet for CMSE (reed) and DMSE (solid-state) sensors, PT ports, an M20x1.5 rod thread, and BSAID mounting options (Basic, FA, LB, TC, TCM1, TCM2).
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 BSAID Clamp Cylinder BSAID100X75S FAQ
It uses a spring-applied, air-released mechanism to grip the rod at any position with a 5500 N static holding force. It is bidirectional and engages only after the cylinder has stopped moving.
The clamp unlocks via a separate G1/8 enclasp port, but only when the air pressures on both sides of the piston are balanced. If not balanced, the rod can jump abruptly upon release.
