Airtac BSAID Clamp Cylinder BSAID63X80S
The AirTAC Airtac BSAID Clamp Cylinder BSAID63X80S 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 BSAID63X80S
The AirTAC BSAID63X80-S is a double-acting ISO 15552 profile cylinder featuring a built-in spring-applied, air-released clamp-lock mechanism. A defining trait of this double-rod series is that it delivers equal thrust in both directions, generating 1402 N of pull force at 0.5 MPa on either side. The integrated enclasp gripper locks the piston rod at any position along its 80 mm travel, delivering a robust static holding force of 2200 N. It is crucial to distinguish this holding force from the cylinder thrust; you must size the clamp's holding capacity against your static load, not the pneumatic push or pull force.
Because it is a double-rod actuator, one end can mount the workpiece while the opposite end attaches a guide, counterweight, or position flag for dual-side guidance and anti-rotation. The clamp operates via a third G1/8 enclasp port, requiring 0.15-0.7 MPa to release. Remember that the variable air cushion only decelerates the piston near stroke ends; the mechanical clamp is what actually secures the load. The lock engages only after the rod has stopped, so it cannot brake a moving rod, and it must be unlocked with balanced 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 BSAID63X80S Is Used
Vertical Lift Holding
Secures elevated loads at any point along the vertical stroke, preventing gravity-driven drops during air pressure loss.
Machining Position Lock
Freezes the double-rod position securely mid-stroke so workpieces remain perfectly aligned during secondary machining or inspection.
Power Failure Safety
The spring-applied clamp engages automatically upon loss of release pressure, holding the load firmly in place anywhere in its travel.
Is the Airtac BSAID Clamp Cylinder BSAID63X80S the Right Clamp-Lock?
Choose this 63 mm bore model when an application requires 1402 N of thrust both ways alongside a 2200 N static hold at any mid-stroke position. If your load is lighter, stepping down to a 50 mm bore provides 825 N of equal thrust and a 1400 N hold. If you only need to secure a load at the stroke end, a SAIL cylinder suffices, but BSAID is required for true lock-anywhere capability. For a standard non-locking double-rod actuator, a plain SAID is the better fit. This BSAID63X80-S variant includes a magnet for CMSE reed and DMSE electronic sensors. It features PT tapered port threads, a 3/8 cylinder port, and accepts Basic, FA, LB, TC, TCM1, or TCM2 mountings (omitting FB, CA, CB, and CR). The 20 mm rod and M16x1.5 thread provide excellent side-load resilience, though external guidance is advised for unsupported loads.
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 BSAID63X80S 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 engages after the cylinder has stopped moving; it cannot brake a moving rod.
The clamp is released by supplying 0.15-0.7 MPa of air to the G1/8 enclasp port. To prevent the rod from jumping abruptly, the air pressures on both sides of the piston must be balanced before unlocking, and the cylinder must be fully stopped.
