About the Airtac BSAI Locking Clamp Cylinder BSAI32X900
The AirTAC BSAI32X900 is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released clamp-lock. It provides a static holding force of 600 N, gripping the 12mm carbon steel rod to secure the load at any position along its 900mm travel. Because this is a non-standard stroke exceeding the 32mm bore's 700mm maximum standard length, it is built to order for extended-travel applications. The base double-acting thrust delivers 402 N at 0.5 MPa, but the 600 N holding force is a separate quantity; you must size the clamp capacity against your static load, not the cylinder thrust.
A critical distinction is that the variable air cushion only decelerates the piston near the stroke ends, whereas the clamp-lock is what actually holds the load. The enclasp mechanism operates via a third G1/8 port, requiring 0.15-0.7 MPa to release the spring pressure. This clamp locks only after the rod has stopped, meaning it cannot brake a moving load. Furthermore, it must be unlocked with balanced air pressures on both sides of the piston, or the rod may jump abruptly upon release. For safety-critical applications, an independent external safety measure is required.

How the Clamp-Lock Holds
static holding force (Ø32 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa (max) | 563 N | — |
Push/pull as tabulated. Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (600 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAI Locking Clamp Cylinder BSAI32X900 Is Used
Vertical Z-Axis Hold
Secures a 32mm bore vertical lifting stage at any point in its 900mm travel, preventing gravity drops when air pressure is removed.
Emergency Power-Loss Hold
Spring-applied clamp engages instantly upon air loss to freeze the rod mid-stroke, protecting operators and workpieces during outages.
Machining Position Lock
Locks the extended rod rigidly at a custom machining location, providing a stable 600 N clamp that resists cutting vibration.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X900 the Right Clamp-Lock?
Choose the BSAI32X900 when you need to hold a load at a specific intermediate point along a long 900mm vertical or horizontal axis without maintaining live air pressure. If your application only requires holding at the stroke ends, the SAIL series is a simpler alternative, but BSAI is necessary for mid-stroke security. If no locking is needed at all, a plain SAI cylinder suffices. For lighter loads, verify the 600 N holding capacity is sufficient; if the static load exceeds this, step up to the 40mm bore, which offers 900 N holding force and 528 N pull thrust at 0.5 MPa.
When replacing this model, match the single-rod configuration, 32mm bore, 900mm stroke, and PT tapered ports. The 32mm bore uses a 1/8 cylinder port alongside the G1/8 unlock port. Acceptable mountings include Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2. Because the stroke is 900mm, an external guide is highly recommended to prevent side-load damage to the 12mm rod and M10x1.25 thread. This configuration does not include a magnet (-S) for CMSE or DMSE sensors.
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 BSAI Locking Clamp Cylinder BSAI32X900 FAQ
The integrated clamp-lock provides a static holding force of 600 N. It grips the 12mm carbon steel rod bidirectionally at any position along the 900mm stroke, holding the load securely without live air pressure.
No, the clamp locks only after the cylinder has stopped; it cannot brake a moving rod. It must be unlocked with balanced air pressures on both sides of the piston, or the rod can jump abruptly. Safety-critical loads require an additional independent safety measure.
