About the Airtac BSAI Locking Clamp Cylinder BSAI32X175
The AirTAC BSAI32X175 is a double-acting ISO 15552 profile cylinder featuring a built-in spring-applied, air-released clamp-lock. It secures the 12mm carbon steel rod at any point along its 175mm travel, delivering a static holding force of 600 N. This bidirectional enclasp mechanism operates via a dedicated G1/8 unlock port, separate from the primary 1/8 PT cylinder ports. Operating pressure ranges from 0.15 to 0.7 MPa to ensure balanced pressure for safe release.
It is crucial to distinguish this 600 N holding force from the cylinder's standard thrust, which reaches 563 N at 0.7 MPa. The clamp is designed to hold a static load, not to brake a moving rod, meaning it only engages after the piston stops. Additionally, the variable air cushion at stroke ends only decelerates the piston; it does not contribute to load retention. For sensing applications, adding a magnet allows the use of AirTAC CMSE reed or DMSE electronic sensors.

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 BSAI32X175 Is Used
Vertical Axis Hold
Prevents gravity-driven drops on vertical lifts by clamping the rod securely at any intermediate stroke position.
Power Loss Safety
Engages automatically during an air or power failure to freeze the piston in place, protecting the work area.
Machining Position Lock
Holds a workpiece rigidly for inspection or light machining without the cylinder drifting under vibration.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X175 the Right Clamp-Lock?
Choose the BSAI32X175 when a load must be held mid-stroke without relying on continuous air pressure. If your application only requires holding at the stroke ends, a plain SAI or SAIL cylinder is sufficient. To step up thrust, the neighbouring 40mm bore provides 628 N push at 0.5 MPa and a 900 N holding force. The 32mm bore uses a 1/8 PT cylinder port and accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 mounts. Standard PT tapered threads are specified. Always ensure pressures are balanced before unlocking, or the rod may jump abruptly; for human-safety critical holds, add an independent mechanical measure.
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 BSAI32X175 FAQ
The clamp-lock provides a static holding force of 600 N. It can hold the load at any position along the stroke, but only after the rod has stopped moving.
The lock is released by applying air to the G1/8 enclasp port, but only after the air pressures on both sides of the piston are balanced. If pressures are unbalanced, the rod can move abruptly upon release.
