Airtac BSAID Clamp Cylinder BSAID32X125S
The AirTAC Airtac BSAID Clamp Cylinder BSAID32X125S is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 125mm 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 600 N.

About the Airtac BSAID Clamp Cylinder BSAID32X125S
The AirTAC BSAID32X125-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 clamps the piston rod to hold the load securely at any position along the 125mm stroke. The integrated clamp provides a static holding force of 600 N. Because this is a double-rod variant, the thrust is equal in both directions at 345 N (0.5 MPa). It is crucial to distinguish this holding force from the cylinder's thrust: the 600 N rating dictates how well the clamp sustains a static load without live pressure, whereas the 345 N thrust drives the motion.
This model includes a magnet (-S) for position sensing with AirTAC CMSE (reed) or DMSE (electronic) switches fitted into the sensor groove. The clamp operates via a separate G1/8 enclasp/unlock port, requiring 0.15-0.7 MPa to release. The rod extends 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 variable air cushion at the stroke ends only decelerates the piston; it does not hold 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 BSAID32X125S Is Used
Vertical Axis Hold
Prevents a vertical payload from dropping when air pressure drops, locking at any position along the 125mm stroke with 600 N of holding force.
Dual-Side Tooling
Uses the double-rod design to mount a workpiece on one end and a guiding flag on the other, maintaining equal 345 N force both ways while resisting rotation.
Inspection Positioning
Secures a part mid-stroke for machining or vision checks, ensuring the load remains completely stationary without relying on continuous live air pressure.
Is the Airtac BSAID Clamp Cylinder BSAID32X125S the Right Clamp-Lock?
Choose this 32mm bore double-rod clamp-lock cylinder when you need equal push/pull force (345 N at 0.5 MPa) and mid-stroke holding on a compact axis. If your application requires higher holding capacity or more drive force, stepping up to the 40mm bore offers 528 N thrust and a 900 N holding force. This BSAID32X125-S is preferred over a SAIL model when you must lock at any position, not just at the stroke ends. A plain SAID cylinder suffices if no clamping is required.
Replacement requires matching the 32mm bore, 125mm stroke, PT ported 1/8 cylinder connections, and the G1/8 unlock port. The double-rod design restricts mounting options to Basic, FA, LB, TC, TCM1, and TCM2 (omitting FB/CA/CB/CR). The 12mm carbon steel rod with an M10x1.25 thread handles moderate side loads, but always ensure the clamp engages only after the rod has completely stopped. It cannot brake a moving rod, and unlocking requires balanced air pressures on both sides to prevent the rod from jumping abruptly. For safety-critical human loads, add an independent mechanical stop.
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 BSAID32X125S FAQ
The built-in clamp-lock provides a static holding force of 600 N. It locks the rod at any position along the stroke, but this is separate from the 345 N thrust that moves the load.
The clamp engages via spring force after the cylinder stops; it cannot brake a moving rod. To unlock it safely, air pressure must be balanced on both sides of the piston via the G1/8 port, otherwise the rod may jump. An independent safety measure is required for human safety.
