About the Airtac BSAID Clamp Cylinder BSAID63X150
The AirTAC BSAID63X150 is a double-acting, double-rod ISO 15552 profile cylinder featuring a spring-applied, air-released clamp-lock. It provides a static holding force of 2200 N and locks the piston rod securely at ANY position along its 150 mm travel. Because it is a double-rod design, the thrust is equal in both directions at 1402 N (at 0.5 MPa). You must size the holding force against your static load, as the 2200 N clamp rating is a separate quantity from the cylinder's thrust.
A 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 lock engages only after the cylinder has stopped, as it cannot brake a moving rod. To release the clamp, air must be applied to the dedicated G1/8 enclasp port, but pressures on both sides of the piston must be balanced first to prevent the rod from jumping abruptly. The variable air cushions only decelerate the piston near stroke ends; they do not hold the load.

How the Clamp-Lock Holds
static holding force (Ø63 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa (max) | 2182 N | — |
Equal force both directions (double rod). Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (2200 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAID Clamp Cylinder BSAID63X150 Is Used
Vertical Axis Holding
Holds a lifted load securely at any point in the 150 mm travel during power loss, preventing gravity-driven drops.
Machining Position Lock
Clamps the double-rod assembly mid-stroke to rigidly secure a part for machining or inspection without live pressure.
Dual-Side Tooling Guidance
Uses one rod end for the workpiece and the opposite end for a counterweight or external guide, locking firmly during transfer.
Is the Airtac BSAID Clamp Cylinder BSAID63X150 the Right Clamp-Lock?
Choose this double-rod clamp-lock cylinder when you need 1402 N of equal thrust in both directions and multi-point holding along the travel. If your application only requires locking at the stroke ends, the AirTAC SAIL series is a simpler choice, while a plain SAID cylinder suffices if no lock is needed. If your static load exceeds 2200 N, stepping up to the 80 mm bore increases the holding force to 3600 N.
As a replacement, match the 63 mm bore, 150 mm stroke, PT port threads, and carbon steel rods. The BSAID mounting set includes Basic, FA, LB, TC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because this model lacks the -S magnet option, it cannot use CMSE reed or DMSE electronic sensors. Always ensure the cylinder has stopped and pressures are balanced before unlocking, and add an independent safety measure 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 BSAID63X150 FAQ
The integrated clamp-lock provides a static holding force of 2200 N. It engages via a spring mechanism at any point along the 150 mm stroke, but only after the piston rod has come to a complete stop.
You must first balance the air pressures on both sides of the piston to prevent the rod from jumping. Then, apply air to the separate G1/8 enclasp port to release the spring-applied clamp.
