Airtac BSAID Clamp Cylinder BSAID50X160
The AirTAC Airtac BSAID Clamp Cylinder BSAID50X160 is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 160mm stroke and a spring-applied, air-released clamp-lock that holds the rod at ANY position along its travel — with a static holding force of 1400 N.

About the Airtac BSAID Clamp Cylinder BSAID50X160
The AirTAC BSAID50X160 is a double-acting ISO 15552 profile cylinder featuring a double-rod design and an integrated spring-applied, air-released clamp-lock. It provides a static holding force of 1400 N at any position along its 160 mm stroke. Because it is a double-rod unit, the thrust is equal in both directions at 825 N (0.5 MPa). It is crucial to distinguish this holding force from the cylinder thrust: the 1400 N clamp secures the static load, whereas the 825 N thrust drives the motion.
The double-rod architecture allows you to mount a workpiece on one end and a guide or counterweight on the other, providing dual-side guidance and anti-rotation. A third G1/8 enclasp port controls the lock, separate from the 1/4 cylinder ports. Remember that the variable air cushion only decelerates the piston near stroke end; the clamp is the true holding mechanism. The lock engages only after the rod stops and requires balanced air pressure to unlock safely.

How the Clamp-Lock Holds
static holding force (Ø50 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa (max) | 1374 N | — |
Equal force both directions (double rod). Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (1400 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAID Clamp Cylinder BSAID50X160 Is Used
Vertical Lift Holding
Maintains a 1400 N vertical load at any mid-stroke position during power loss, preventing gravity-driven drops on dual-sided guided lifts.
Machining Position Lock
Secures a dual-sided workpiece fixture rigidly for machining or inspection, using the double-rod for anti-rotation stability.
Emergency Safety Stop
Holds the load securely anywhere in the 160 mm travel during an E-stop, though an independent backup measure is required for human safety.
Is the Airtac BSAID Clamp Cylinder BSAID50X160 the Right Clamp-Lock?
Choose this double-rod clamp-lock model when you need equal push and pull thrust (825 N both ways) combined with multi-axis stability. If your application only requires holding at the stroke end, a plain SAIL or SAID cylinder suffices, but the BSAID50X160 locks anywhere. If your load exceeds 1400 N, step up to bore 63, which offers 1402 N pull thrust and a 2200 N holding force. For lighter loads, bore 40 provides 528 N thrust and a 900 N hold.
This clamp locks only after the rod has stopped; it cannot brake a moving load. If human safety depends on the hold, add an independent safety measure. The lock must release with balanced piston pressures to prevent the rod from jumping. This 50 mm bore uses PT port threads, a 20 mm carbon steel rod (M16x1.5 thread), and accepts Basic, FA, LB, TC, TCM1, or TCM2 mounts (omitting FB/CA/CB/CR). Without a -S magnet, it cannot use CMSE or DMSE sensors.
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 BSAID50X160 FAQ
It provides a static holding force of 1400 N and locks at any position along the 160 mm stroke. The clamp is spring-applied and bidirectional, holding the rod securely whether it was extending or retracting.
The clamp is not a brake; it only locks after the cylinder has stopped. To unlock it safely via the G1/8 enclasp port, the air pressures on both sides of the piston must be balanced, otherwise the rod can move abruptly.
