About the Airtac BSAI Locking Clamp Cylinder BSAI63X160S
The AirTAC BSAI63X160-S is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released clamp-lock. It provides a static holding force of 2200 N at any position along its 160 mm stroke. Because it includes a magnet, it is fully compatible with AirTAC CMSE reed and DMSE solid-state sensors for precise position feedback.
It is crucial to distinguish holding force from cylinder thrust: the 2200 N clamp grip is a static load-holding value, entirely separate from the 2182 N of dynamic push thrust generated at 0.7 MPa. The variable air cushion at the stroke ends only decelerates the piston to prevent impact damage; it does not hold the load. The clamp mechanism requires a third G1/8 enclasp port and operates only after the rod has stopped moving, meaning it cannot function as an active brake.

How the Clamp-Lock Holds
static holding force (Ø63 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa (max) | 2182 N | — |
Push/pull as tabulated. Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (2200 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAI Locking Clamp Cylinder BSAI63X160S Is Used
Vertical Axis Holding
Prevents gravity-driven drops on vertical lifts by clamping the rod at any intermediate height during an unexpected air pressure loss.
Power Outage Safety
Maintains position securely anywhere in the travel range when facility power or compressed air is lost, ensuring loads do not drift.
Machining Position Lock
Freezes the workpiece at a precise mid-stroke coordinate for stable machining or inspection, unlocking only under balanced pressure.
Is the Airtac BSAI Locking Clamp Cylinder BSAI63X160S the Right Clamp-Lock?
Choose this 63 mm bore when an application requires 1559 N of thrust at 0.5 MPa to move the load, but 2200 N of static holding force to keep it safely parked mid-stroke. If you only need to hold the load at the fully extended or retracted stroke end, a plain SAIL stroke-end lock or a standard SAI cylinder would suffice. Step up to the 80 mm bore if the 3600 N holding capacity is insufficient for your static load.
This model locks only after the cylinder has stopped, and it must be unlocked with balanced air pressures on both sides of the piston to prevent the rod from jumping abruptly. For safety-critical loads, an additional independent mechanical measure is required. The 160 mm stroke is standard, and the robust M16x1.5 rod thread handles high side loads. Replacement requires a single-rod, 63 mm bore, 160 mm stroke unit with PT ports, a CMSE/DMSE compatible magnet, and the BSAI mounting set (Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, TCM2).
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 BSAI63X160S FAQ
It is a spring-applied, air-released mechanism that provides a static holding force of 2200 N at any position along the stroke. It engages only after the cylinder has completely stopped moving and cannot be used to brake a moving rod.
The clamp is released via a separate G1/8 enclasp port, but only when the air pressures on both sides of the piston are balanced. If the pressures are not equalized, the rod can move abruptly upon release, creating a pinch hazard.
