Airtac BSAID Clamp Cylinder BSAID100X75
The AirTAC Airtac BSAID Clamp Cylinder BSAID100X75 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 BSAID100X75
The AirTAC BSAID100X75 is a double-acting ISO 15552 profile cylinder featuring a rod extending from both ends and a built-in clamp-lock mechanism. A spring-applied, air-released gripper clamps the piston rod to secure the load 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 (at 0.5 MPa). It is crucial to distinguish this holding force from the cylinder thrust: you must size the clamp's 5500 N capacity against your static load, not the pneumatic thrust.
The second rod allows you to mount a workpiece on one end and a guide, counterweight, or position flag on the other, providing dual-side anti-rotation guidance. The clamp operates via a separate G1/8 enclasp port, requiring 0.15-0.7 MPa to release. Remember that the variable air cushions only decelerate the piston near stroke ends; the mechanical clamp is what actually holds the load. Operating speed is 30-500 mm/s.

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 BSAID100X75 Is Used
Vertical Load Holding
Secures a 100 mm bore lifting axis at any intermediate height with 5500 N of holding force, preventing gravity-driven drops during an air loss event.
Machining Position Lock
Freezes the dual-rod workpiece platform rigidly in place for drilling or inspection, using the second rod for an external guide to resist cutting torque.
Emergency Stop Safety
Holds the load securely mid-stroke when power is removed, though an independent secondary safety measure is required for human-safe zones.
Is the Airtac BSAID Clamp Cylinder BSAID100X75 the Right Clamp-Lock?
Choose this double-rod model when your application requires equal force both ways and dual-side mounting. If you only need unidirectional thrust, a single-rod BSAI100X75 offers the same 5500 N holding capacity. If you need to hold heavier loads, stepping up is not an option as 125 mm is the largest bore (8600 N hold, 5734 N thrust). For lighter vertical axes, a BSAI80X200 provides 3600 N of holding force.
This clamp locks only AFTER the cylinder has stopped; it cannot brake a moving rod. It must be unlocked with balanced air pressures on both sides of the piston, or the rod may jump abruptly. Safety-critical loads require an additional independent safety measure. This replacement uses PT tapered ports (1/2 inch cylinder, G1/8 enclasp), a 25 mm carbon steel rod with an M20x1.5 thread, and accepts Basic, FA, LB, TC, TCM1, or TCM2 mountings (omitting FB/CA/CB/CR). No magnet is specified.
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 BSAID100X75 FAQ
The clamp-lock provides a static holding force of 5500 N. It engages via a spring-applied gripper at any position along the stroke and is released only when 0.15-0.7 MPa of air is applied to the G1/8 enclasp port.
The clamp locks only after the cylinder has stopped moving; it cannot brake a moving rod. You must balance the air pressure on both sides of the piston before unlocking, or the rod may jump abruptly. For human-safety applications, an additional independent safety measure is required.
