About the Airtac BSAID Clamp Cylinder BSAID40X600S
The AirTAC BSAID40X600-S is a double-acting ISO 15552 profile cylinder featuring a double-rod configuration and a built-in spring-applied, air-released clamp-lock. It delivers a bidirectional static holding force of 900 N, gripping the 16mm carbon steel rod securely at any position along its 600mm travel. Because it is a double-rod design, thrust is equal in both directions at 528 N (0.5 MPa), making it ideal for dual-side guidance or mounting a counterweight on the opposing rod end.
Crucially, the 900 N clamp holding force is a distinct quantity from the cylinder's 528 N thrust; you must size the holding force against your static load, not the push/pull thrust. The lock engages via a separate G1/8 enclasp port, but only after the piston has come to a complete stop, meaning it cannot brake a moving rod. Additionally, the variable air cushions at the stroke ends only decelerate the piston, they do not hold the load, and unlocking requires balanced air pressures to prevent abrupt rod movement.

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 BSAID40X600S Is Used
Vertical Load Holding
Maintains vertical payloads securely at any point in the 600mm travel using its 900N clamp, preventing gravity-driven falls when air pressure drops.
Power Failure Safety
The spring-applied enclasp engages instantly upon air loss, freezing the double-rod position to protect nearby equipment and workpieces.
Machining Position Lock
Freezes the 16mm rod rigidly during drilling or inspection processes, ensuring the workpiece mounted on the rod end remains completely stationary.
Is the Airtac BSAID Clamp Cylinder BSAID40X600S the Right Clamp-Lock?
Choose this BSAID40X600-S when a process requires holding a load mid-stroke on a vertical axis or during power loss, where a plain double-rod SAID would fail. If your application only needs locking at the stroke ends, the simpler SAIL series suffices. For lighter loads, the 32mm bore offers 345 N thrust and 600 N holding force, while stepping up to the 50mm bore provides 825 N thrust and 1400 N holding force. Always remember the clamp locks only after the rod stops, and safety-critical loads need an independent backup.
This 600mm stroke exceeds 300mm, so an external guide is recommended to prevent side-loading on the 16mm rod and M12x1.25 thread. This unit includes PT ports, a standard magnet for CMSE reed and DMSE solid-state sensors, and accepts Basic, FA, LB, TC, TCM1, or TCM2 mounts, omitting the FB/CA/CB/CR brackets due to its double-rod design.
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 BSAID40X600S FAQ
The spring-applied clamp provides a static holding force of 900 N. It locks the 16mm carbon steel rod at any position bidirectionally, but only engages after the cylinder has stopped moving.
The lock is released via the G1/8 enclasp port, but only when air pressures on both sides of the piston are balanced. Releasing without balanced pressure can cause abrupt rod movement, so an independent safety measure is required for human-safety loads.
