Airtac BSAID Clamp Cylinder BSAID100X900
The AirTAC Airtac BSAID Clamp Cylinder BSAID100X900 is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 900mm 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 BSAID100X900
The AirTAC BSAID100X900 is a double-acting ISO 15552 profile cylinder featuring a double-rod configuration and a built-in spring-applied, air-released clamp-lock. It secures the load at any position along its 900mm stroke, delivering a static holding force of 5500 N. Because it is a double-rod actuator, the thrust is identical in both directions, generating 3681 N of pull force at 0.5 MPa. Buyers must distinguish this holding force from thrust: the 5500 N clamp capacity resists the static load, whereas the 3681 N thrust drives the motion.
The dual-rod design allows you to mount a workpiece on one end and a counterweight, guide, or position flag on the opposite end, providing dual-side guidance and anti-rotation. A third G1/8 enclasp port controls the unlock mechanism, which requires balanced air pressures on both sides of the piston to prevent the rod from jumping abruptly upon release. Furthermore, the variable air cushion at the stroke ends only decelerates the piston; it does not hold the load, as only the mechanical clamp provides true position maintenance.

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 BSAID100X900 Is Used
Vertical Lift Holding
Locks a raised platform at any point in the 900mm travel with 5500 N of static force to prevent gravity-induced drops during air loss.
Machining Position Freeze
Secures a dual-sided workpiece fixture rigidly in place for milling or inspection, using the second rod for anti-rotation guidance.
Power Failure Safety
Spring-applied clamp engages instantly anywhere along the stroke during an outage to hold the load without relying on live air pressure.
Is the Airtac BSAID Clamp Cylinder BSAID100X900 the Right Clamp-Lock?
Choose this double-rod model when equal force and anti-rotation are required; if you do not need a second rod, a single-rod BSAI100X900 offers the same 5500 N holding capacity. Stepping down to a bore 80 reduces the clamp hold to 3600 N and the pull thrust to 2268 N at 0.5 MPa, whereas moving up to a 125 bore increases the hold to 8600 N. Select BSAID over a stroke-end-only SAIL model when you must freeze the load mid-travel. The clamp locks only after the rod stops, so it cannot brake moving loads, and safety-critical applications need an independent external measure.
For replacement, verify the 100mm bore, 900mm stroke, and PT-threaded 1/2 cylinder ports (plus the G1/8 enclasp port). The BSAID mounting set omits FB, CA, CB, and CR, accepting Basic, FA, LB, TC, TCM1, and TCM2. This 900mm stroke exceeds 300mm, so an external guide is strongly recommended to manage side loads on the extended rod.
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 BSAID100X900 FAQ
The built-in clamp-lock provides a static holding force of 5500 N. It locks at any position along the stroke and holds bidirectionally, but it only engages after the cylinder has stopped moving.
The clamp is released via a third G1/8 enclasp port. You must balance the air pressure on both sides of the piston before unlocking, otherwise the rod may jump abruptly. The clamp is not a moving-rod brake.
