Airtac BSAID Clamp Cylinder BSAID80X225S
The AirTAC Airtac BSAID Clamp Cylinder BSAID80X225S is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 225mm 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 3600 N.

About the Airtac BSAID Clamp Cylinder BSAID80X225S
The AirTAC BSAID80X225-S is a double-acting ISO 15552 profile cylinder featuring a double-rod configuration and a spring-applied, air-released clamp-lock. It secures the load at any position along its 225 mm stroke, delivering a static holding force of 3600 N. Because it is a double-rod actuator, it generates equal thrust in both directions (2268 N at 0.5 MPa), allowing you to mount a workpiece on one end and a guide or position flag on the opposite end for dual-side anti-rotation.
It is vital to distinguish this 3600 N static holding force from the cylinder's 2268 N thrust; you must size the clamp against the static load, not the drive force. The mechanism uses a third G1/8 enclasp port to release the rod, separate from the 3/8 cylinder ports. Remember that the variable air cushion only decelerates the piston near stroke ends, while the clamp is the actual load-holding device. Operating pressure is 0.15-0.7 MPa.

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 BSAID80X225S Is Used
Vertical Axis Mid-Stroke Hold
Secures a vertically lifted payload at any point in the 225 mm travel, preventing falls if air pressure drops while providing equal force for both up and down strokes.
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 deflection.
Emergency Power-Loss Hold
The spring-applied clamp engages automatically when air is lost, freezing the load instantly wherever it has stopped along the stroke.
Is the Airtac BSAID Clamp Cylinder BSAID80X225S the Right Clamp-Lock?
Choose this double-rod model when a project requires equal push/pull force and dual-end tooling. If you do not need a second rod, a single-rod BSAI80 offers the same 3600 N holding force but less thrust on the return. If you only need to hold at the stroke end, a plain SAIL80 suffices, but BSAID is required for mid-stroke security. The 25 mm rod and M20x1.5 thread provide excellent side-load capacity, though any stroke over 300 mm still demands an external guide.
This BSAID80X225-S replaces any double-rod ISO 15552 actuator of the same bore and stroke. It uses PT tapered ports and accepts Basic, FA, LB, TC, TCM1, or TCM2 mounts (omitting FB/CA/CB/CR). The -S magnet works with AirTAC CMSE (reed) and DMSE (electronic) sensors. Note that the clamp locks only after the rod stops, it cannot brake a moving load, and it requires balanced piston pressure to unlock safely without jumping. Safety-critical applications need an independent external measure.
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 BSAID80X225S FAQ
The clamp-lock provides a static holding force of 3600 N. This is separate from the cylinder's 2268 N thrust, and it holds the rod securely at any position along the 225 mm stroke.
No, the lock engages only after the cylinder has stopped and cannot brake a moving load. It must be unlocked with balanced air pressure on both sides of the piston, or the rod may jump abruptly.
