About the Airtac BSAID Clamp Cylinder BSAID40X600
The AirTAC BSAID40X600 is a double-acting ISO 15552 profile cylinder featuring a rod extending from both ends and an integrated clamp-lock mechanism. A spring-applied, air-released gripper secures the piston rod at any position along the 600mm travel, providing a static holding force of 900 N. Because it is a double-rod unit, the thrust is equal in both directions at 528 N (based on 0.5 MPa), allowing perfectly symmetrical push and pull operations. A critical distinction to remember is that this 900 N holding force is entirely separate from the cylinder's thrust; you must size the clamp capacity against the static load weight, not the motive force.
The clamp operates via a third G1/8 enclasp port and requires a balanced air pressure of 0.15-0.7 MPa to release safely. It locks only after the cylinder has come to a complete stop, meaning it cannot brake a moving rod. The double-rod design serves a specific purpose beyond equal force: it allows mounting a workpiece on one end and a guide, counterweight, or position flag on the opposite end, providing dual-side guidance and anti-rotation. Furthermore, the variable air cushion at the stroke ends only decelerates the piston; the clamp is the true holding device.

How the Clamp-Lock Holds
static holding force (Ø40 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa (max) | 880 N | — |
Equal force both directions (double rod). Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (900 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAID Clamp Cylinder BSAID40X600 Is Used
Vertical Load Holding
Secures a vertically lifted workpiece at any height along the 600mm travel, preventing gravity-driven drops during an air pressure loss.
Machining Position Lock
Locks a dual-side guided fixture rigidly in place during drilling or milling, ensuring the rod cannot shift despite cutting vibrations.
Dual-Tool Assembly Station
Mounts a primary assembly tool on one rod end and a counterweight or alignment flag on the opposite end for balanced, anti-rotation handling.
Is the Airtac BSAID Clamp Cylinder BSAID40X600 the Right Clamp-Lock?
Choose this double-rod clamp-lock model when you need to prevent a load from dropping or shifting at any intermediate point along a 600mm travel. If your application only requires holding at the extreme stroke ends, a simpler SAIL stroke-end lock would suffice; the BSAID is necessary for mid-stroke security. If no locking is needed at all, a standard SAID double-rod cylinder is the appropriate choice. When sizing, remember that the 900 N clamp holds the load statically, while the 528 N thrust moves it. If your load exceeds 900 N, step up to a bore 50 unit, which offers a 1400 N holding force and 825 N pull thrust.
At 600mm stroke, the 16mm carbon steel rod and M12x1.25 thread provide a robust interface, but the extended length means an external guide rail is strongly recommended to handle side loads and prevent binding. The BSAID40X600 uses PT tapered ports (1/4 cylinder port, G1/8 enclasp port) and accepts a reduced mounting set (Basic, FA, LB, TC, TCM1, TCM2) because the double-rod design omits FB, CA, CB, and CR mounts. This specific configuration ships without a magnet; add an -S version if you require CMSE reed or DMSE solid-state position 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 BSAID Clamp Cylinder BSAID40X600 FAQ
The static holding force is 900 N. It is a bidirectional clamp that locks the rod at any position, but it only engages after the cylinder has stopped; it cannot brake a moving load.
The clamp releases only when air pressure is balanced on both sides of the piston via the G1/8 enclasp port; unbalanced pressure causes abrupt rod movement. The double rod provides equal 528 N thrust both ways and allows mounting a guide or tool on the opposite end for anti-rotation.
