Airtac BSAID Clamp Cylinder BSAID80X1000S
The AirTAC Airtac BSAID Clamp Cylinder BSAID80X1000S is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 1000mm 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 3600 N.

About the Airtac BSAID Clamp Cylinder BSAID80X1000S
The AirTAC BSAID80X1000-S is a double-acting ISO 15552 profile cylinder featuring a double-rod configuration and a spring-applied, air-released clamp-lock mechanism. It secures the load at any position along its 1000 mm travel with a static holding force of 3600 N. Because it is a double-rod design, the thrust is equal in both directions, delivering 2268 N of push and pull force at 0.5 MPa. It is crucial to distinguish this holding force from the cylinder thrust: the 3600 N clamp rating is the static capacity to maintain a stopped position, whereas the 2268 N thrust is the dynamic motion capability.
This model uses a 25 mm carbon steel rod with an M20x1.5 thread extending from both ends, allowing you to mount a workpiece on one side and a counterweight or position flag on the other for dual-side guidance. The clamp requires a third G1/8 enclasp port to release the rod, operating within a 0.15-0.7 MPa pressure range. Furthermore, the variable air cushions only decelerate the piston near the stroke ends; they do not hold the load, as that function belongs entirely to the mechanical clamp.

How the Clamp-Lock Holds
static holding force (Ø80 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa (max) | 3519 N | — |
Equal force both directions (double rod). Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (3600 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAID Clamp Cylinder BSAID80X1000S Is Used
Vertical Axis Intermediate Hold
Secures a heavy vertical lift at any point in the 1000 mm travel using the 3600 N clamp, preventing a crash drop during power loss while maintaining equal push and pull force.
Dual-Side Machining Fixture
Mounts a machining head on one rod end and an anti-rotation guide on the opposite end, locking the assembly rigidly at a precise intermediate machining coordinate.
Emergency Stop Positioning
Holds a stopped workpiece safely in the middle of the stroke during an emergency stop, acting as a static brake that requires balanced pressure to release safely.
Is the Airtac BSAID Clamp Cylinder BSAID80X1000S the Right Clamp-Lock?
Choose this 80 mm bore double-rod model when an application requires equal force both directions and intermediate stopping, stepping down from a 125 mm bore (5734 N thrust, 8600 N holding force) if you need a lighter footprint, or up from a 63 mm bore (1402 N thrust, 2200 N holding force) for heavier loads. A plain SAID suffices if you only need equal bi-directional force without mid-stroke holding, while a SAIL is restricted to stroke-end locking only. The clamp locks only after the rod has stopped; it cannot brake a moving load. It must be unlocked with balanced air pressures on both sides of the piston, or the rod may jump abruptly. For safety-critical human loads, add an independent safety measure.
As a direct replacement, match the double-rod design, 80 mm bore, 1000 mm stroke, PT port threads, and the -S magnet option for CMSE (reed) and DMSE (electronic) sensors. The double-rod design omits the FB, CA, CB, and CR mounts, accepting only Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because the stroke is 1000 mm, the long unsupported rod requires an external guide to handle side loads, despite the robust 25 mm rod diameter.
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 BSAID80X1000S FAQ
The spring-applied clamp provides a static holding force of 3600 N. It engages at any position along the 1000 mm stroke to hold a stopped load, functioning bidirectionally whether the rod was extending or retracting.
The clamp unlocks only when air pressure is applied to the G1/8 enclasp port and the pressures on both sides of the piston are balanced. If the cylinder is not stopped and balanced before unlocking, the rod can move abruptly. It is not a moving-rod brake.
