Airtac BSAID Clamp Cylinder BSAID63X80
The AirTAC Airtac BSAID Clamp Cylinder BSAID63X80 is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 80mm 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 BSAID63X80
The AirTAC BSAID63X80 is a double-acting ISO 15552 profile cylinder featuring a rod out both ends and a built-in clamp-lock mechanism. A spring-applied, air-released gripper engages the rod to hold the load securely at any position along the 80 mm 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, while the rod extending from both ends allows you to mount a workpiece on one side and a guide or position flag on the opposite side for dual-side anti-rotation.
It is crucial to distinguish holding force from cylinder thrust: the 2200 N clamp grip is entirely separate from the 1402 N pneumatic driving force, meaning you must size the clamp against the static load, not the motion thrust. The clamp uses a dedicated G1/8 enclasp port and locks only after the piston has stopped, serving as a position hold rather than a braking device. Furthermore, the variable air cushion at the ends only decelerates the piston near stroke limits; it does not hold the load. The clamp must be released with balanced air pressures to prevent the rod from jumping abruptly.

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 BSAID63X80 Is Used
Vertical Axis Hold
Locks a lifted payload at any height along the 80 mm stroke with 2200 N of holding force, preventing sudden drops during power loss.
Machining Position Hold
Secures the double-rod assembly firmly mid-stroke so a workpiece mounted on the opposite end remains rigid during processing.
Emergency Stop Safety
Engages the rod only after motion stops to freeze the load in place, requiring an independent safety measure for human-safe areas.
Is the Airtac BSAID Clamp Cylinder BSAID63X80 the Right Clamp-Lock?
Choose this double-rod model when you need symmetrical force and dual-side mounting capabilities. If your application only requires holding at the stroke end, a plain SAI or SAIL cylinder would suffice, but the BSAID63X80 is necessary for locking mid-travel. If you need a higher holding capacity, stepping up to the bore 80 provides a 3600 N clamp and 2268 N thrust; dropping to bore 50 offers 1400 N holding and 825 N thrust.
When replacing this unit, match the 63 mm bore, 80 mm stroke, PT ported 3/8 cylinder connections, and the double-rod configuration. The BSAID mounting set omits FB, CA, CB, and CR brackets, accepting only Basic, FA, LB, TC, TCM1, and TCM2. The 20 mm rod and M16x1.5 thread handle side loads well, though long unsupported strokes still need an external guide. If position sensing is required, add the -S magnet for CMSE reed or DMSE electronic sensors.
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 BSAID63X80 FAQ
The spring-applied, air-released clamp-lock provides a static holding force of 2200 N. It engages the rod to hold the load at any position along the stroke, operating bidirectionally whether the rod was extending or retracting.
The clamp uses a separate G1/8 enclasp port and must only be unlocked when the air pressures on both sides of the piston are balanced and the cylinder has stopped. Releasing it under unbalanced pressure can cause the rod to jump abruptly. It locks only after the rod stops, so it cannot brake a moving load.
