About the Airtac BSAID Clamp Cylinder BSAID63X225
The AirTAC BSAID63X225 is a double-acting ISO 15552 profile cylinder featuring a double-rod configuration and a spring-applied, air-released clamp-lock. It delivers an equal thrust of 1402 N in both directions at 0.5 MPa, while the integrated enclasp mechanism provides a static holding force of 2200 N. A critical distinction exists here: the 2200 N holding force is a separate clamping metric from the cylinder's thrust, meaning you must size the clamp against the static load, not the push or pull force.
This bidirectional clamp locks the piston rod at any position along the 225 mm stroke, but only after the cylinder has come to a complete stop; it cannot brake a moving load. Unlocking requires balanced air pressure on both sides of the piston via the dedicated G1/8 enclasp port, preventing abrupt rod jumps. The double-rod design allows mounting a workpiece on one end and a guide or position flag on the other for dual-side anti-rotation. Additionally, the variable air cushion at stroke ends only decelerates the piston; the clamp itself is what holds the load securely.

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 BSAID63X225 Is Used
Vertical Axis Load Holding
Secures a vertically lifted workpiece at any point in the 225 mm travel, using the 2200 N clamp to prevent gravity-induced drops when air pressure is removed.
Power Loss Safety Hold
The spring-applied clamp engages automatically during an air supply failure, freezing the double-rod position safely until pressure is restored and balanced.
Machining Position Lock
Locks the part rigidly at a specific intermediate stroke position for a machining or inspection process, utilizing the opposing rod end for a secondary tool or flag.
Is the Airtac BSAID Clamp Cylinder BSAID63X225 the Right Clamp-Lock?
Choose this double-rod BSAID63X225 when an application requires equal force both directions and multi-sided guidance via a rod extending from each end. If you need higher clamping capacity, stepping up to the bore 80 model provides a 3600 N hold, while dropping to bore 50 reduces the hold to 1400 N. This model outperforms a stroke-end-only SAIL lock by holding anywhere in the travel, though a plain SAID suffices if live pressure always remains on. Remember that safety-critical holds require an independent external measure, as the clamp is not a dynamic brake.
For replacement, match the double-rod layout, 63 mm bore, 225 mm stroke, PT ported 3/8 cylinder ports, and the G1/8 enclasp port. The BSAID mounting set omits FB, CA, CB, and CR brackets, accepting only Basic, FA, LB, TC, TCM1, and TCM2. Since this is a non-magnet version, position sensing via CMSE or DMSE switches is not supported without a -S variant. The 20 mm rod and M16x1.5 thread offer robust side-load handling, though strokes approaching 300 mm still benefit from an external guide.
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 BSAID63X225 FAQ
The integrated clamp-lock provides a static holding force of 2200 N. It locks the rod at any position along the stroke, but only after the cylinder has stopped moving; it cannot brake a moving rod.
The clamp unlocks only when air pressure is applied to the G1/8 enclasp port and the pressures on both sides of the piston are balanced. If pressures are not balanced, the rod can move abruptly upon release, so ensure the cylinder is stopped before unlocking.
