About the Airtac BSAID Clamp Cylinder BSAID32X125
The AirTAC BSAID32X125 is a double-acting ISO 15552 profile cylinder featuring a double-rod configuration and a spring-applied, air-released clamp-lock. It provides a static holding force of 600 N at any position along its 125 mm travel. Because it is a double-rod unit, the thrust is equal in both directions at 345 N (0.5 MPa). Remember that holding force and thrust are distinct metrics; you must size the 600 N clamp capacity against your static load, not the cylinder's push thrust.
A core benefit of the dual-rod design is enabling dual-side guidance or anti-rotation, allowing you to mount a workpiece on one end and a position flag or secondary tool on the other. The clamp operates via a separate G1/8 enclasp port and requires balanced pressure to unlock safely, preventing the rod from jumping abruptly. Note that the variable air cushion only decelerates the piston near stroke ends; the mechanical clamp is the sole device holding the load.

How the Clamp-Lock Holds
static holding force (Ø32 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa (max) | 563 N | — |
Equal force both directions (double rod). Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (600 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAID Clamp Cylinder BSAID32X125 Is Used
Vertical Mid-Stroke Hold
Locks a vertically lifted load securely at any point in the 125 mm travel, preventing sudden drops during cycle pauses.
Power Failure Safety
The spring-applied clamp engages automatically upon air loss, holding the double-rod payload steady anywhere in its path.
Machining Position Hold
Uses the dual-rod anti-rotation feature to clamp a workpiece firmly for intermediate machining or inspection without live pressure.
Is the Airtac BSAID Clamp Cylinder BSAID32X125 the Right Clamp-Lock?
Choose this 32 mm bore model when an application requires holding a load mid-stroke, a task a plain SAID cannot perform. If you only need holding at the stroke end, the SAIL series suffices. If you need higher mid-stroke holding capacity, step up to the 40 mm bore, which offers 528 N of thrust and a 900 N clamp force. Remember the clamp locks only after the rod stops; it cannot brake a moving load. Safety-critical applications require an independent backup measure.
This cylinder uses PT threaded ports (1/8 cylinder, G1/8 enclasp). The 12 mm carbon steel rod provides a robust interface for moderate side loads. The double-rod design restricts mounting options to Basic, FA, LB, TC, TCM1, and TCM2. As no magnet is specified, it will not support CMSE or DMSE sensors without modification.
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 BSAID32X125 FAQ
The clamp-lock provides a static holding force of 600 N. It engages via spring pressure to hold the load securely at any position along the stroke, independent of the cylinder's 345 N thrust.
The double-rod design provides equal thrust both ways and allows dual-side guidance. It omits the FB, CA, CB, and CR mounts, accepting only Basic, FA, LB, TC, TCM1, and TCM2. The clamp unlocks only with balanced piston pressure to prevent abrupt rod movement.
