About the Airtac BSAID Clamp Cylinder BSAID100X300
The AirTAC BSAID100X300 is a double-acting ISO 15552 profile cylinder featuring a rod extending from both ends and an integrated clamp-lock mechanism. It delivers a bidirectional thrust of 3681 N at 0.5 MPa, ensuring equal force whether extending or retracting. The spring-applied, air-released enclasp gripper locks the rod at any position along the 300 mm travel, providing a static holding force of 5500 N. Remember that this holding force is distinct from thrust; you must size the clamp's holding capacity against the static load, not the cylinder's dynamic push force.
This model uses a third G1/8 enclasp port to release the lock, requiring 0.15-0.7 MPa of balanced air pressure to unlock safely. The variable air cushion at stroke ends only decelerates the piston; the clamp itself is what secures the load. The double-rod design allows mounting a workpiece on one end and a guide or position flag on the opposite end, providing dual-side guidance and anti-rotation. It operates at 30-500 mm/s and integrates AirTAC CMSE reed and DMSE electronic sensors via its side grooves.

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 BSAID100X300 Is Used
Vertical Lift Holding
Secures elevated platforms at any intermediate height along the travel, preventing sudden drops during power loss.
Machining Position Lock
Locks the dual rods firmly during milling or drilling operations, using the second rod end for anti-rotation guidance.
Emergency Safety Stop
Holds the load instantly upon air loss at any stroke position, providing a reliable fail-safe mid-cycle.
Is the Airtac BSAID Clamp Cylinder BSAID100X300 the Right Clamp-Lock?
Choose this double-rod BSAID100X300 when your application demands equal force in both directions and anti-rotation guidance via a secondary rod end. If you need less holding capacity, the 80 mm bore offers a 3600 N clamp force and 2268 N pull thrust; if you require more, the 125 mm bore provides 8600 N holding force and 5734 N thrust. Select this clamp-lock over a stroke-end-only SAIL when you must secure the load at an intermediate point. Unlike a plain SAID, this model holds position without live air pressure.
The clamp locks only after the rod has stopped; it cannot brake a moving load. Furthermore, it must be unlocked with balanced pressures on both piston sides, or the rod may jump abruptly. Safety-critical applications require an independent external measure. This 300 mm stroke benefits from an external guide to support side loads. Replacement specs: double rod, 100 mm bore, 300 mm stroke, PT ports, 1/2 cylinder port, G1/8 enclasp port, and mounting options limited to Basic, FA, LB, TC, TCM1, TCM2 (omitting FB/CA/CB/CR).
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 BSAID100X300 FAQ
The integrated clamp-lock provides a static holding force of 5500 N. It locks the rod at any position along the stroke, holding the load securely without continuous air pressure.
The clamp locks only after the cylinder has stopped and cannot brake a moving rod. To unlock it safely, you must apply balanced air pressure to both sides of the piston via the G1/8 enclasp port; otherwise, the rod may jump abruptly.
