About the Airtac BSAI Locking Clamp Cylinder BSAI32X800
The AirTAC BSAI32X800 is a double-acting ISO 15552 profile cylinder featuring a built-in spring-applied, air-released clamp-lock. It provides a static holding force of 600 N, gripping the 12 mm carbon steel rod to secure loads at any position along its 800 mm travel. This bidirectional enclasp mechanism operates via a dedicated G1/8 unlock port, separate from the 1/8 cylinder ports, requiring 0.15-0.7 MPa to release the grip.
It is crucial to distinguish this 600 N holding force from the cylinder thrust, which is 402 N push at 0.5 MPa; buyers must size the clamp against the static load, not the thrust. Furthermore, the variable air cushion only decelerates the piston near stroke ends and does not contribute to holding the load. The clamp locks only after the rod has completely stopped, meaning it cannot brake a moving rod, and unlocking requires balanced air pressure to prevent abrupt rod movement.

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 BSAI32X800 Is Used
Vertical Axis Hold
Prevents gravity-driven drops on vertical lifts by clamping the rod securely at any point in the 800 mm travel.
Power Loss Safety
Spring-applied enclasp engages automatically during air pressure loss to freeze the payload exactly where it stopped.
Machining Position Hold
Locks the workpiece rigidly at a custom intermediate height for stable machining or inspection without end-stop reliance.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X800 the Right Clamp-Lock?
Select this 32 bore model when an application demands mid-stroke holding rather than end-of-stroke locking, making it superior to a SAIL cylinder. If the 600 N holding capacity or 402 N thrust is insufficient, stepping up to a 40 bore offers 528 N pull thrust and a 900 N clamp. For simple extension tasks without position holding, a plain SAI cylinder suffices. This specific 800 mm stroke exceeds the 32 bore maximum standard stroke of 700 mm, classifying it as non-standard; at this length, the 12 mm rod and M10x1.25 thread have limited side-load capacity, so an external guide rail is strongly recommended to prevent rod deflection.
When replacing a unit, match the single-rod configuration, 32 mm bore, 800 mm stroke, and PT port threads. The correct mounting set for this single-rod version includes Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2. As specified without a magnet (-S), this unit does not support CMSE or DMSE sensors. Safety-critical loads must use an additional independent safety measure, as the clamp unlocks only when piston pressures are balanced.
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 BSAI32X800 FAQ
The built-in clamp-lock provides a static holding force of 600 N. It grips the rod bidirectionally at any position, but only after the cylinder has stopped moving.
The clamp is released via a third G1/8 enclasp port at 0.15-0.7 MPa. Air pressure must be balanced on both sides of the piston before unlocking, or the rod may jump abruptly. It is not a braking device for moving loads.
