About the Airtac BSAI Locking Clamp Cylinder BSAI80X100
The AirTAC BSAI80X100 is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released clamp-lock mechanism. It provides a robust static holding force of 3600 N and delivers 2513 N of push thrust at 0.5 MPa. You must distinguish between holding force and thrust: the 3600 N rating defines the clamp's grip on the rod to hold a static load, whereas the 2513 N thrust dictates the cylinder's dynamic moving power.
This enclasp unit locks the piston rod at any position along its 100 mm travel, operating bidirectionally. The clamp utilizes a third G1/8 unlock port and requires a balanced 0.15-0.7 MPa air pressure to release safely. The variable air cushions only decelerate the piston near stroke ends; they do not hold the load. A 25 mm carbon steel rod with an M20x1.5 thread handles high side-load stress, and the extruded aluminum barrel accepts CMSE reed or DMSE electronic sensors.

How the Clamp-Lock Holds
static holding force (Ø80 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa (max) | 3519 N | — |
Push/pull as tabulated. Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (3600 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAI Locking Clamp Cylinder BSAI80X100 Is Used
Vertical Load Holding
Prevents gravity-driven drops on vertical axes by clamping the 25 mm rod at any point in the 100 mm stroke with 3600 N of static force.
Power Loss Safety
Spring-applied enclasp engages automatically upon air failure, securing the payload mid-travel without relying on live pressure.
Machining Position Lock
Freezes the workpiece securely during drilling or milling operations, ensuring the variable cushion does not allow unwanted load drift.
Is the Airtac BSAI Locking Clamp Cylinder BSAI80X100 the Right Clamp-Lock?
Select this 80 mm bore when your application requires 2513 N of dynamic thrust but a much higher 3600 N static load hold. If you need less force, the 63 mm bore offers 1559 N thrust and a 2200 N hold; if your load exceeds 3600 N, step up to the 100 mm bore with its 5500 N hold. Choose this BSAI over a SAIL model when you must secure the load mid-stroke rather than only at the end. If you simply need standard movement without a lock, a plain SAI cylinder suffices.
For safe operation, remember the clamp engages only after the rod completely stops; it cannot brake a moving load. Unlocking requires balanced air pressures on both piston sides to prevent abrupt rod jumping. Safety-critical applications need an independent external measure. This BSAI80X100 features PT tapered ports, a 3/8 cylinder port, and accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, or TCM2 mounts. Since no -S magnet is specified, position sensing requires adding a magnet.
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 BSAI80X100 FAQ
The clamp-lock provides a static holding force of 3600 N. It grips the rod bidirectionally at any position along the 100 mm stroke, but only locks after the cylinder has stopped moving.
The clamp uses a third G1/8 port and requires 0.15-0.7 MPa air pressure to release. You must balance the air pressure on both sides of the piston before unlocking, or the rod may jump abruptly.
