Airtac BSAID Clamp Cylinder BSAID100X80
The AirTAC Airtac BSAID Clamp Cylinder BSAID100X80 is a genuine double-acting ISO 15552 cylinder with a Ø100mm 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 5500 N.

About the Airtac BSAID Clamp Cylinder BSAID100X80
The AirTAC BSAID100X80 is a double-acting ISO 15552 profile cylinder featuring a double-rod design and an integrated spring-applied, air-released clamp-lock. It provides a static holding force of 5500 N, gripping the rod to hold the load securely at any position along its 80 mm travel. Because it is a double-rod unit, the thrust is equal in both directions at 3681 N at 0.5 MPa. A crucial distinction is that this holding force is entirely separate from the cylinder thrust; you must size the clamp's 5500 N capacity against your static load, not the pneumatic push force.
The dual-rod architecture serves a specific purpose: mounting a workpiece on one end and a guide, counterweight, or position flag on the opposite end for dual-side anti-rotation guidance. The clamp requires a third G1/8 enclasp port and unlocks only when air pressures on both sides of the piston are balanced. Remember that the variable air cushion only decelerates the piston near stroke end; the mechanical clamp is what actually holds the load. This unit uses PT tapered ports and lacks a standard magnet.

How the Clamp-Lock Holds
static holding force (Ø100 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa (max) | 5498 N | — |
Equal force both directions (double rod). Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (5500 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAID Clamp Cylinder BSAID100X80 Is Used
Mid-Stroke Vertical Hold
Suspends heavy vertical loads at any point in the 80 mm travel, preventing sudden drops during an air pressure loss.
Machining Position Lock
Freezes the dual-rod stage securely for a secondary operation, using the 5500 N clamp to resist cutting forces.
Power-Loss Safety Hold
Maintains the exact position of a workpiece anywhere along the stroke when supply air is removed, ensuring operator safety.
Is the Airtac BSAID Clamp Cylinder BSAID100X80 the Right Clamp-Lock?
Select this 100 mm bore model when an application demands 3681 N of thrust both ways alongside a robust 5500 N holding capacity. If your load is lighter, the 80 mm bore offers 2268 N pull thrust and a 3600 N hold, making it a more compact alternative. Choose this BSAID clamp-lock over a stroke-end-only SAIL cylinder when you must freeze the load mid-stroke rather than solely at the extremes. If no holding is required at all, a plain SAID double-rod cylinder suffices.
The clamp locks only after the rod has completely stopped; it cannot brake a moving load. Safety-critical applications require an additional independent safety measure. To unlock safely, balance the pressures or the rod may jump abruptly. This stroke is short, so side-load stress is minimal, but the M20x1.5 rod thread handles lateral forces well. Replacement requires a double-rod 100x80 body with PT ports, a G1/8 unlock port, and a BSAID mounting set (Basic, FA, LB, TC, TCM1, TCM2). Add an -S magnet if you need 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 BSAID100X80 FAQ
The integrated clamp-lock provides a static holding force of 5500 N. It engages via a spring to hold the rod at any position, but it only locks after the cylinder has stopped moving; it cannot brake a moving rod.
The clamp is released by supplying air to the G1/8 enclasp port, but only after the air pressures on both sides of the piston are balanced. If pressures are not balanced, the rod can move abruptly upon release. An independent safety measure is required for human-safety loads.
