Airtac BSAID Clamp Cylinder BSAID100X300S
The AirTAC Airtac BSAID Clamp Cylinder BSAID100X300S is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 300mm 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 BSAID100X300S
The AirTAC BSAID100X300-S is a double-acting ISO 15552 profile cylinder featuring a double-rod layout and a spring-applied, air-released clamp-lock mechanism. Because it is a double-rod design, the thrust is equal in both directions at 3681 N (0.5 MPa), and the second rod allows you to mount a workpiece on one end and a guide or position flag on the other for dual-side anti-rotation. The integrated enclasp gripper locks the piston rod at any position along the 300 mm travel, delivering a static holding force of 5500 N.
It is vital to distinguish this 5500 N static holding force from the 3681 N dynamic thrust—the clamp size must match your static load, not the cylinder push force. Furthermore, the variable air cushion at the stroke ends only decelerates the piston; the clamp is the sole device that holds the load. The mechanism requires a third G1/8 enclasp port to release the lock, and it operates safely within the 0.15-0.7 MPa pressure range.

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 BSAID100X300S Is Used
Vertical Load Holding
Freezes a heavy vertical lift at any intermediate height using 5500 N of holding force, preventing gravity-driven drops during an air pressure loss.
Machining Position Lock
Secures a dual-side workpiece or fixture rigidly in place for drilling or milling, using the second rod for an anti-rotation guide.
Emergency Safety Stop
Holds the mechanism in place mid-stroke if power fails, though human-safety applications require an independent mechanical backup.
Is the Airtac BSAID Clamp Cylinder BSAID100X300S the Right Clamp-Lock?
Choose this double-rod model when you need symmetric force and dual-end tooling; if you do not need a rod out both ends, the single-rod BSAI100X300 offers the same 5500 N holding capacity. If your application only requires holding at the stroke end, a plain SAIL lock cylinder suffices, but choose BSAID when you must freeze the load at any intermediate point. Remember that the clamp locks only after the rod stops—it cannot brake a moving load, and unlocking requires balanced air pressures to prevent the rod from jumping abruptly.
This 100 mm bore unit uses PT tapered ports (1/2 inch cylinder port, G1/8 enclasp port) and includes a -S magnet for precise positioning via CMSE reed or DMSE electronic sensors. The BSAID mounting set omits FB, CA, CB, and CR brackets, offering Basic, FA, LB, TC, TCM1, and TCM2. At a 300 mm stroke, the M20x1.5 rod thread handles side loads well, but an external guide is recommended for unsupported lengths.
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 BSAID100X300S FAQ
The spring-applied clamp-lock provides a static holding force of 5500 N. It locks the rod at any position bidirectionally, but only after the cylinder has stopped moving.
The lock 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 unbalanced, the rod can move abruptly upon release.
