About the Airtac BSAID Clamp Cylinder BSAID63X700S
The AirTAC BSAID63X700-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 700 mm travel, delivering a static holding force of 2200 N. Because it is a double-rod design, the thrust is equal in both directions at 1402 N (0.5 MPa), and the second rod allows you to mount a position flag, counterweight, or secondary tool on the opposite end for dual-side guidance.
It is vital to distinguish this 2200 N static holding force from the cylinder's 1402 N thrust; the mechanical clamp sustains the stationary load, while thrust drives the movement. Furthermore, the variable air cushion only decelerates the piston near the stroke ends, whereas the actual locking is handled by the dedicated enclasp mechanism. This clamp requires a third G1/8 unlock port and a balanced air pressure of 0.15-0.7 MPa to release safely.

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 BSAID63X700S Is Used
Vertical Axis Intermediate Hold
Secures a vertically lifted payload at any point along the 700 mm travel, preventing sudden drops during a power loss without relying on stroke-end stops.
Machining Position Lock
Clamps a dual-sided workpiece fixture rigidly in place for machining or inspection, using the second rod for a counterweight or alignment flag.
Emergency Safety Hold
Provides a reliable 2200 N static hold to freeze motion safely, though an independent safety measure is required for human-life critical loads.
Is the Airtac BSAID Clamp Cylinder BSAID63X700S the Right Clamp-Lock?
Choose this 63 mm bore when an application requires 1402 N of equal bidirectional thrust alongside a robust 2200 N holding capability. If your load demands less force, the 50 mm bore provides 825 N of thrust and 1400 N of holding force; for heavier loads, step up to the 80 mm bore with 2268 N of thrust and 3600 N of holding force. Select this BSAID model over a stroke-end-only SAIL cylinder when you must lock the rod securely at any intermediate point, or choose a plain SAID if no locking is necessary.
For replacement, verify the double-rod design, 700 mm stroke, PT port threads, and the -S magnet for CMSE reed or DMSE electronic sensors. The BSAID mounting set includes Basic, FA, LB, TC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the stroke is 700 mm, an external guide is recommended to manage side loads on the extended rod. Remember that the clamp locks only after the cylinder has stopped, it cannot brake a moving rod, and it must be unlocked with balanced pressures to prevent the rod from jumping abruptly.
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 BSAID63X700S FAQ
The clamp provides a static holding force of 2200 N. It is a spring-applied, air-released mechanism that locks the rod at any position bidirectionally, but it only engages after the cylinder has stopped moving and cannot act as a dynamic brake.
The clamp is released via a third G1/8 enclasp port, requiring a balanced air pressure between 0.15 and 0.7 MPa. If the pressures on both sides of the piston are not balanced when unlocked, the rod may move abruptly, presenting a hazard.
