About the Airtac BSAI Locking Clamp Cylinder BSAI32X100S
The AirTAC BSAI32X100-S is a double-acting ISO 15552 profile cylinder equipped with a spring-applied, air-released clamp-lock. It secures the 12 mm carbon steel rod at any position along its 100 mm travel, delivering a static holding force of 600 N. Operating at 0.15-0.7 MPa, it generates 563 N of practical thrust at maximum pressure. It is crucial to distinguish holding force from thrust: the 600 N clamp rating is the capacity to hold a static load, which is separate from the 563 N used to move the load.
This unit features a PT 1/8 cylinder port and a dedicated G 1/8 enclasp port for the unlocking mechanism. The integrated variable air cushion only decelerates the piston near the stroke ends; the clamp itself is what holds the load. Equipped with a magnet (-S), it supports AirTAC CMSE reed and DMSE solid-state sensors for position detection.

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 BSAI32X100S Is Used
Vertical Load Holding
Prevents gravity-driven drops on vertical axes by clamping the rod securely at any height during travel.
Power Loss Safety
Spring-applied engagement locks the rod instantly upon air pressure loss, holding the workpiece safely in place.
Machining Position Hold
Freezes the rod at a specific intermediate point for precise machining or inspection tasks without end-stop reliance.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X100S the Right Clamp-Lock?
Choose this 32 mm bore when you need to secure a load mid-stroke rather than just at the ends. If your application only requires holding at the fully extended or retracted position, a plain SAI or SAIL stroke-end lock cylinder would suffice. If the 600 N holding force is insufficient, stepping up to a 40 mm bore increases the static hold to 900 N and the thrust to 879 N. Remember the clamp locks only after the rod stops; it cannot brake a moving piston. Always unlock with balanced air pressures to prevent the rod from jumping, and add independent safety measures for human safety.
This BSAI32X100-S configuration has a single rod, 100 mm stroke, PT 1/8 porting, and a 12 mm M10x1.25 rod thread. It accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 mounts. The -S magnet enables CMSE/DMSE sensing.
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 BSAI32X100S FAQ
The clamp-lock provides a static holding force of 600 N. It can hold the load at any position along the stroke, but it only engages after the cylinder has stopped moving and cannot be used to brake a moving rod.
The clamp is released by applying 0.15-0.7 MPa of air pressure to the G 1/8 enclasp port. To prevent the rod from jumping abruptly, the air pressures on both sides of the piston must be balanced before unlocking.
