Airtac BSAID Clamp Cylinder BSAID63X600S
The AirTAC Airtac BSAID Clamp Cylinder BSAID63X600S is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 600mm 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 BSAID63X600S
The AirTAC BSAID63X600-S is a double-acting ISO 15552 profile cylinder featuring a double-rod configuration and a spring-applied, air-released clamp-lock mechanism. It delivers an equal thrust of 1402 N in both directions at 0.5 MPa. The integrated enclasp gripper locks the piston rod at any position along its 600 mm travel, providing a static holding force of 2200 N. It is crucial to distinguish this holding force from the cylinder thrust; you must size the 2200 N clamp capacity against your static load, not the 1402 N thrust. A third G1/8 enclasp port supplies the unlock pressure.
Because it is a double-rod design, you can mount a workpiece on one end and a position flag or secondary guide on the opposite end, utilizing the dual-side guidance for anti-rotation. The clamp locks bidirectionally but only after the cylinder has stopped; it cannot brake a moving rod. Note that the variable air cushion only decelerates the piston near the stroke ends, while the clamp itself performs the actual holding. The -S magnet enables position sensing with CMSE reed or DMSE electronic switches.

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 BSAID63X600S Is Used
Vertical Axis Holding
Locks a 1402 N load at any intermediate height along the 600 mm vertical travel without relying on continuous air pressure.
Power Loss Safety
The spring-applied clamp engages automatically during a pneumatic power failure, securely holding the load wherever it stopped.
Machining Position Hold
Uses the double-rod design to mount a part on one end and a counterweight on the other, locking rigidly for secondary processing.
Is the Airtac BSAID Clamp Cylinder BSAID63X600S the Right Clamp-Lock?
Choose this 63 mm bore if you need 1402 N of equal bidirectional thrust and a 2200 N static hold anywhere in a 600 mm stroke. If your application only requires holding at the stroke end, a SAIL cylinder suffices, but BSAI/BSAID is necessary for intermediate locking. If you need less force, the 50 mm bore offers 825 N thrust and a 1400 N hold; for more, the 80 mm bore provides 2268 N thrust and a 3600 N hold. Because this is a 600 mm stroke, the M16x1.5 rod provides good side-load capacity, but an external guide is still recommended for unsupported loads. Replacements must match the double rod, PT port threads, and the BSAID mounting set (Basic, FA, LB, TC, TCM1, TCM2), omitting FB/CA/CB/CR.
For safe operation, always balance the air pressures on both sides of the piston before unlocking. Releasing the clamp with unbalanced pressure will cause the rod to jump abruptly. If human safety depends on the hold, an additional independent safety measure is required, as the clamp is not a dynamic brake. Operating pressure is 0.15-0.7 MPa.
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 BSAID63X600S FAQ
The clamp-lock provides a static holding force of 2200 N. It is bidirectional and can hold the load at any position along the 600 mm stroke, but only after the rod has completely stopped moving.
The clamp uses a third G1/8 port and requires balanced air pressure on both sides of the piston to unlock. If pressures are not balanced, the rod can jump abruptly upon release. It is not a dynamic brake and cannot stop a moving load.
