Airtac BSAID Clamp Cylinder BSAID63X700
The AirTAC Airtac BSAID Clamp Cylinder BSAID63X700 is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 700mm 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 2200 N.

About the Airtac BSAID Clamp Cylinder BSAID63X700
The AirTAC BSAID63X700 is a double-acting ISO 15552 profile cylinder featuring a double-rod configuration and an integrated clamp-lock mechanism. A spring-applied, air-released gripper clamps the piston rod to secure the load at ANY position along the 700mm stroke, providing a static holding force of 2200 N. Because it is a double-rod design, the thrust is equal in both directions at 1402 N at 0.5 MPa, and the second rod allows you to mount a workpiece on one end and a guide or position flag on the other.
It is critical to distinguish this 2200 N static holding force from the 1402 N cylinder thrust: you must size the clamp against the static load weight, not the pneumatic push force. Furthermore, the variable air cushion only decelerates the piston near the stroke ends; the clamp is the actual holding device. Unlocking requires a third G1/8 enclasp port and balanced air pressure of 0.15-0.7 MPa on both sides of the piston to prevent the rod from jumping abruptly upon release.

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 BSAID63X700 Is Used
Vertical Axis Mid-Travel Hold
Secures a vertically lifted payload at any point along the 700mm stroke using the 2200 N clamp, preventing falls during an air pressure loss.
Machining Position Lock
Holds a dual-sided workpiece rigidly in place for intermediate machining or inspection, using the second rod for an anti-rotation guide.
Emergency Drop Prevention
Acts as a fail-safe gripping mechanism that engages instantly when the cylinder stops, protecting operators and tooling from sudden drops.
Is the Airtac BSAID Clamp Cylinder BSAID63X700 the Right Clamp-Lock?
Choose this double-rod clamp-lock cylinder when a process requires dual-side guidance, anti-rotation, or mounting a secondary tool opposite the primary workpiece, alongside mid-stroke position holding. If you do not need a second rod, the single-rod BSAI63X200 offers the same 2200 N holding force in a simpler package. If you only need to hold at the stroke ends rather than anywhere in travel, a SAIL cylinder suffices. Conversely, stepping up to the 80mm bore increases both thrust and the holding force to 3600 N.
As a replacement match, ensure you specify a double-rod setup, 63mm bore, 700mm stroke, and PT port threads. The BSAID mounting set omits FB, CA, CB, and CR brackets, accepting only Basic, FA, LB, TC, TCM1, and TCM2 styles. At 700mm of travel, the 20mm rod and M16x1.5 thread provide stiffness, but an external guide is highly recommended to manage side loads on such a long stroke. Note that the clamp locks only after the rod has stopped; it cannot brake a moving load, and safety-critical applications require an independent external safety 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 BSAID63X700 FAQ
It uses a spring-applied, air-released mechanism to grip the rod at any position, providing a 2200 N static holding force. Because it is a double-rod cylinder, it delivers an equal thrust of 1402 N in both directions. The clamp engages only after the cylinder has stopped moving.
The clamp must be released using the G1/8 enclasp port only after the air pressures on both sides of the piston are balanced. If pressures are unbalanced, the rod can jump abruptly. Since the lock cannot brake a moving rod, human-safety applications require an additional independent safety measure.
