Airtac BSAID Clamp Cylinder BSAID100X225
The AirTAC Airtac BSAID Clamp Cylinder BSAID100X225 is a genuine double-acting ISO 15552 cylinder with a Ø100mm 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 5500 N.

About the Airtac BSAID Clamp Cylinder BSAID100X225
The AirTAC BSAID100X225 is a double-acting ISO 15552 profile cylinder featuring a rod out both ends and a spring-applied, air-released clamp-lock. It secures the carbon steel piston rod at any position along its 225 mm stroke, delivering a static holding force of 5500 N. Because it is a double-rod variant, the thrust is symmetrical, generating 3681 N of force in both extend and retract directions at 0.5 MPa. It is vital to distinguish this holding force from the cylinder thrust: the 5500 N rating dictates the static load capacity against gravity, while the 3681 N thrust drives the motion.
This enclasp mechanism requires a third G1/8 pneumatic port to release the lock, operating on a balanced-pressure principle. The clamp only engages after the rod has completely stopped, meaning it cannot function as a dynamic brake for a moving load. Furthermore, the dual-rod design allows you to mount a workpiece on one end and a position flag or secondary guide on the opposite end, providing anti-rotation stability and dual-side guidance rather than merely doubling the force.

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 BSAID100X225 Is Used
Vertical Axis Holding
Suspends heavy vertical loads at any point in the 225 mm travel using the 5500 N static clamp, preventing gravity-driven drops during power loss.
Machining Position Lock
Freezes the dual rods at a precise intermediate coordinate for a machining or inspection process, keeping the workpiece entirely stationary without relying on live air pressure.
Dual-Side Tooling Mount
Utilizes the rod extending from both ends to mount a primary workpiece on one side and a counterweight or alignment guide on the opposite side, ensuring stable operation.
Is the Airtac BSAID Clamp Cylinder BSAID100X225 the Right Clamp-Lock?
Select this 100 mm bore double-rod model when an application requires equal push and pull forces—3681 N in both directions—along with mid-stroke holding. If your load demands less force, stepping down to the 80 mm bore offers 2268 N of thrust and a 3600 N holding force. Conversely, the 125 mm bore provides 5734 N of symmetrical thrust and an 8600 N hold. The BSAID100X225 outperforms a stroke-end-only SAIL cylinder by clamping anywhere along the travel, though a plain SAID is sufficient if locking is entirely unnecessary.
When integrating this cylinder, note that its PT-threaded cylinder port is 1/2 and the enclasp port is G1/8. The double-rod configuration supports Basic, FA, LB, TC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR. Since this model lacks a magnet (-S), position sensing requires a custom solution. Always ensure pressures are balanced before unlocking to prevent the rod from jumping abruptly, and add independent safety measures for human-safety-critical holds.
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 BSAID100X225 FAQ
The BSAID100X225 provides a static holding force of 5500 N. Unlike a SAIL cylinder that only locks at the stroke ends, this clamp-lock mechanism secures the rod at any position along the entire 225 mm stroke.
The clamp is spring-applied and air-released via a third G1/8 port. It only unlocks when the air pressures on both sides of the piston are balanced and the rod has stopped. Releasing it without balanced pressure can cause the rod to jump abruptly, so independent safety measures are required for human-safety-critical loads.
