About the Airtac BSAI Locking Clamp Cylinder BSAI100X200
The AirTAC BSAI100X200 is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released clamp-lock that grips the rod at any position along its 200 mm travel. It delivers a practical maximum thrust of 5497 N at 0.7 MPa, while the independent enclasp mechanism provides a static holding force of 5500 N. You must size the holding force against your static load, as this clamp capacity is entirely separate from the cylinder's push thrust.
A third G1/8 unlock port supplies 0.15-0.7 MPa to release the grip, separate from the 1/2 inch main cylinder ports. Remember that the variable air cushions only decelerate the piston near the stroke ends; the mechanical clamp is what actually holds the load. The clamp locks only after the rod has stopped and cannot brake a moving load.

How the Clamp-Lock Holds
static holding force (Ø100 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa (max) | 5498 N | — |
Push/pull as tabulated. Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (5500 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAI Locking Clamp Cylinder BSAI100X200 Is Used
Mid-Stroke Vertical Hold
Pauses and locks a heavy vertical lift at any intermediate height without maintaining live air pressure.
Power Loss Safety
Engages the 5500 N clamp automatically upon air loss to freeze the payload exactly where it stopped.
Machining Position Lock
Secures a heavy workpiece rigidly in place at a specific coordinate for drilling or inspection.
Is the Airtac BSAI Locking Clamp Cylinder BSAI100X200 the Right Clamp-Lock?
Choose this 100 mm bore when a 80 mm bore (providing 2513 N thrust and 3600 N holding force) is insufficient to safely secure your static load. If you only need to hold a load at the fully extended or retracted stroke end, a SAIL cylinder is a simpler choice; the BSAI is specifically required when you must lock at an intermediate position. For applications without any holding requirement, a plain SAI cylinder suffices.
This single-rod model accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 mounts. It uses PT port threads and lacks a standard magnet, so position sensing is not available without modification. Because the stroke is 200 mm, side-load is minimal, but the robust 25 mm rod and M20x1.5 thread handle high axial and minor offset loads effectively. Always unlock with balanced piston pressures to prevent the rod from jumping, and add independent safety measures for human-safety-critical applications.
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 BSAI100X200 FAQ
The clamp-lock provides a static holding force of 5500 N. It is bidirectional and can secure the rod at any position along the stroke, but only after the cylinder has come to a complete stop.
The clamp is released by applying 0.15-0.7 MPa to the G1/8 enclasp port. You must balance the air pressures on both sides of the piston before unlocking, or the rod may jump abruptly. It cannot be used to brake a moving rod.
