Airtac BSAID Clamp Cylinder BSAID40X1000S
The AirTAC Airtac BSAID Clamp Cylinder BSAID40X1000S is a genuine double-acting ISO 15552 cylinder with a Ø40mm 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 900 N.

About the Airtac BSAID Clamp Cylinder BSAID40X1000S
The AirTAC BSAID40X1000-S 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 1000 mm stroke, delivering a static holding force of 900 N. Because it is a double-rod unit, the thrust is equal in both directions at 528 N (based on 0.5 MPa), and having a rod extending from both ends allows you to mount a workpiece on one side and a guide or counterweight on the other for dual-side anti-rotation. Note that the 900 N holding force is a separate metric from the 528 N thrust; you must size the clamp force against the static load, not the cylinder's push capability.
The clamp mechanism uses a dedicated G1/8 enclasp port to release the grip, requiring a balanced air pressure between 0.15 and 0.7 MPa on both piston sides to unlock safely. The variable air cushions at stroke ends only decelerate the piston; they do not hold the load. For position sensing, the included -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors in the standard groove.

How the Clamp-Lock Holds
static holding force (Ø40 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa (max) | 880 N | — |
Equal force both directions (double rod). Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (900 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAID Clamp Cylinder BSAID40X1000S Is Used
Vertical Z-Axis Hold
Secures a vertically mounted lifting tool at any point in its 1000 mm travel, preventing gravity-driven drops during an unexpected air pressure loss.
Machining Position Lock
Clamps a dual-sided workpiece fixture rigidly in place for a secondary machining or inspection process, using the second rod for a position flag.
Power Failure Safety
Engages instantly upon air loss to freeze the double-rod payload exactly where it stopped, ensuring the process remains safe until pressure is restored.
Is the Airtac BSAID Clamp Cylinder BSAID40X1000S the Right Clamp-Lock?
Choose this BSAID40X1000-S when you need a double-rod cylinder that holds position mid-stroke without relying on a stroke-end detent like the SAIL series. If your application only requires standard end-of-stroke holding, a plain SAID40 cylinder would suffice without the extra clamp plumbing. If you need higher holding power, stepping up to the 50 mm bore provides a 1400 N clamp force and 825 N pull thrust. Conversely, dropping to a 32 mm bore reduces the holding capacity to 600 N. Remember that the clamp locks only after the rod has completely stopped; it cannot brake a moving load, and safety-critical applications require an independent external safety measure.
As a replacement match, verify the double-rod design, 40 mm bore, 1000 mm stroke, and PT tapered port threads. The BSAID series supports a narrower mounting set than single-rod BSAI: Basic, FA, LB, TC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because this is a 1000 mm stroke on a 40 mm bore (exceeding the 800 mm standard max for this size), it is a non-standard stroke that absolutely requires an external guide to prevent excessive side-loading on the 16 mm rod and M12x1.25 rod threads.
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 BSAID40X1000S FAQ
The clamp-lock provides a static holding force of 900 N. It is spring-applied and air-released, meaning it grips the rod at any position along the 1000 mm stroke automatically when air pressure is removed or drops below 0.15 MPa.
No. The clamp is designed to hold a load only after the cylinder has come to a complete stop; it cannot brake a moving rod. Additionally, the lock must be released with balanced air pressures on both sides of the piston, or the rod may jump abruptly upon unlocking.
