About the Airtac BSAI Locking Clamp Cylinder BSAI32X800S
The AirTAC BSAI32X800-S is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released clamp-lock. It provides bidirectional holding at any position along its 800 mm stroke, delivering a static holding force of 600 N. Operating at a practical pressure range of 0.15-0.7 MPa, the 32 mm bore generates up to 563 N of thrust. You must size the holding force against your static load, as the 600 N clamp capacity is entirely separate from the 563 N cylinder thrust.
This unit includes a -S magnet for CMSE reed and DMSE electronic sensors. The enclasp mechanism uses a third G1/8 port for unlocking. Remember that the variable air cushion only decelerates the piston near stroke ends; the clamp itself is what holds the load. Furthermore, the clamp locks only after the rod has stopped moving and cannot act as a brake.

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 BSAI32X800S Is Used
Vertical Z-Axis Holding
Secures a 32 mm bore vertical load at any intermediate height with 600 N of holding force, preventing drops during an unexpected air pressure loss.
Machining Position Lock
Clamps the extended rod rigidly in place during drilling or inspection processes, ensuring the workpiece remains completely stationary.
Emergency Mid-Stroke Stop
Holds the load safely wherever the rod stopped along the 800 mm travel during a power outage, requiring balanced pressure to release safely.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X800S the Right Clamp-Lock?
Choose this non-standard 800 mm stroke model when you need position-holding capability mid-travel on a long axis, rather than just at the stroke end like the SAIL type. If your application requires less travel, stepping down to a 50 mm bore offers 982 N thrust and 1400 N holding force. Because this stroke is 800 mm on a 12 mm rod, the unsupported length is highly susceptible to side loads; an external guide rail is strongly recommended to prevent rod bending.
The clamp locks only after the cylinder stops and must be unlocked with balanced air pressures to prevent the rod from jumping abruptly. For safety-critical holding, add an independent mechanical measure. This single-rod configuration uses a PT port thread, an M10x1.25 rod thread, and accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, or TCM2 mounts.
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 BSAI32X800S FAQ
The integrated clamp-lock provides a static holding force of 600 N. It locks the rod bidirectionally at any position along the 800 mm stroke, but only engages after the cylinder has stopped moving.
The clamp is spring-applied and air-released via a third G1/8 port. You must balance the air pressures on both sides of the piston before unlocking, otherwise the rod may jump abruptly. It cannot brake a moving rod.
