About the Airtac BSAID Clamp Cylinder BSAID80X50
The AirTAC BSAID80X50 is a double-acting ISO 15552 profile cylinder featuring a double-rod design and a built-in spring-applied, air-released clamp-lock. It provides a static holding force of 3600 N and can secure the load at any position along its 50 mm stroke. Because it is a double-rod actuator, it delivers equal thrust in both directions (2268 N at 0.5 MPa), allowing you to mount a workpiece on one end and a guide or counterweight on the opposite end for dual-side anti-rotation.
It is crucial to distinguish holding force from cylinder thrust: the 3600 N clamp grip is a separate static metric from the 2268 N pneumatic thrust, meaning you must size the clamp against the static load, not the drive force. The clamp engages via a dedicated G1/8 enclasp port but only locks after the rod has completely stopped; it cannot brake a moving load. Furthermore, unlocking requires balanced air pressures on both piston sides to prevent the rod from jumping abruptly upon release.

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 | — |
Equal force both directions (double rod). 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 BSAID Clamp Cylinder BSAID80X50 Is Used
Vertical Z-Axis Hold
Secures a lifted platen at any point in the 50 mm travel during an unexpected power loss, relying on the 3600 N clamp rather than live air pressure.
Machining Position Lock
Freezes the double-rod carriage securely for a secondary machining or inspection operation, using the second rod end for a position flag.
Dual-Side Tooling Mount
Mounts a primary workpiece on one rod end and a counterweight on the other to maintain equal 2268 N thrust and balance during clamped dwell periods.
Is the Airtac BSAID Clamp Cylinder BSAID80X50 the Right Clamp-Lock?
Choose this double-rod model when an application demands equal bidirectional force and dual-side guidance. If you do not need a rod extending from both ends, the single-rod BSAI80X50 offers the same 3600 N holding capacity but higher extending thrust. Alternatively, if holding is only required at the stroke end, a plain SAID or SAIL cylinder suffices. For safety-critical vertical loads, remember that this clamp locks only after the cylinder stops and requires an additional independent safety measure.
This BSAID80X50 configuration uses a carbon steel rod, PT tapered ports, and operates at 0.15-0.7 MPa. It omits the FB, CA, CB, and CR foot mounts, accepting only Basic, FA, LB, TC, TCM1, and TCM2 brackets. Without a magnet specified, it cannot use CMSE reed or DMSE electronic sensors. The robust 25 mm rod and M20x1.5 thread provide excellent side-load resistance, though long unsupported strokes still need an external guide.
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 BSAID80X50 FAQ
It provides a static holding force of 3600 N. The spring-applied clamp locks the rod at any position bidirectionally, but only after the cylinder has stopped moving. It is not designed to brake a moving rod.
Release requires applying air to the G1/8 enclasp port after balancing pressures on both piston sides to prevent abrupt rod movement. Unlike the single-rod BSAI, this double-rod BSAID offers equal thrust both ways and omits FB, CA, CB, and CR mounting brackets.
