About the Airtac BSAID Clamp Cylinder BSAID80X75
The AirTAC BSAID80X75 is a double-acting ISO 15552 profile cylinder featuring a double-rod configuration and an integrated 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 3600 N. Because it is a double-rod design, the cylinder generates equal thrust in both directions, providing 2268 N of push and pull force at 0.5 MPa. It is crucial to distinguish this holding force from the cylinder thrust: the 3600 N rating dictates the static load capacity when locked, whereas the 2268 N thrust drives the motion.
This model features a 25 mm carbon steel rod with an M20x1.5 thread extending from both ends, allowing you to mount a workpiece on one side and a guide or position flag on the other for dual-side anti-rotation. The clamp utilizes a dedicated G1/8 enclasp port, separate from the 3/8 cylinder ports, and requires balanced air pressure to unlock safely. Furthermore, the variable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load, as only the mechanical clamp provides true position retention.

How the Clamp-Lock Holds
static holding force (Ø80 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa (max) | 3519 N | — |
Equal force both directions (double rod). Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (3600 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAID Clamp Cylinder BSAID80X75 Is Used
Vertical Axis Hold
Secures a vertically lifted payload at any intermediate height with 3600 N of holding force, preventing drops if air pressure is lost.
Machining Position Lock
Freezes the double-rod assembly mid-stroke to rigidly hold a part for machining or inspection without relying on continuous pneumatic thrust.
Dual-Side Emergency Stop
Uses the second rod end for a position flag while the clamp safely halts the load anywhere in its travel during a power loss event.
Is the Airtac BSAID Clamp Cylinder BSAID80X75 the Right Clamp-Lock?
Choose the BSAID80X75 when an application demands equal force both ways and mid-stroke holding without live air pressure. If your load requires less holding capacity, the bore 63 double-rod version provides 1402 N of bidirectional thrust and a 2200 N holding force. Conversely, heavier payloads might necessitate the 125 bore, which yields 5734 N of thrust and 8600 N of holding force. Select this clamp-lock model over a standard SAID when the load must be frozen at a specific intermediate stroke position, whereas a plain SAID suffices if holding is only needed at the stroke ends via cushions.
When integrating this cylinder, note that the clamp locks only after the rod has completely stopped; it cannot brake a moving load. You must balance the air pressures on both sides of the piston before releasing the clamp, or the rod may jump abruptly. For safety-critical operations, an independent external measure is required. This double-rod variant supports Basic, FA, LB, TC, TCM1, and TCM2 mounts, omitting the FB, CA, CB, and CR brackets found on single-rod versions. As specified, this unit uses PT tapered ports and lacks a magnet for CMSE or DMSE sensors.
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 BSAID80X75 FAQ
The BSAID80X75 provides a static holding force of 3600 N. This bidirectional clamp locks the rod at any position along the stroke, and this holding capacity is separate from the 2268 N of equal thrust the cylinder generates in both directions.
The clamp is spring-applied and air-released via a dedicated G1/8 port. It only locks after the cylinder has stopped moving and cannot brake a moving rod. To unlock it safely, the air pressures on both sides of the piston must be balanced, otherwise the rod may jump abruptly upon release.
