Airtac BSAID Clamp Cylinder BSAID50X160S
The AirTAC Airtac BSAID Clamp Cylinder BSAID50X160S 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 BSAID50X160S
The AirTAC BSAID50X160-S is a double-acting ISO 15552 profile cylinder featuring a rod out both ends and an integrated clamp-lock mechanism. A spring-applied, air-released enclasp gripper secures the carbon steel rod at any position along its 160 mm travel, delivering a static holding force of 1400 N. Because it is a double-rod design, thrust is equal in both directions at 825 N (0.5 MPa), and the second rod allows you to mount a position flag or secondary tool while providing dual-side guidance.
It is critical to distinguish holding force from cylinder thrust: the 1400 N clamp rating secures the static load, whereas the 825 N thrust moves the payload. The clamp operates via a third G1/8 enclasp port and requires 0.15-0.7 MPa to unlock. Remember that the variable air cushion only decelerates the piston near stroke end; the mechanical clamp is what actually holds the load. Furthermore, the clamp locks only after the rod stops and must be released with balanced pressures to prevent sudden rod jumping.

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 BSAID50X160S Is Used
Vertical Axis Hold
Prevents gravity-driven drops on vertical lifts by clamping the rod at any mid-stroke position during a power loss.
Machining Position Lock
Secures the workpiece rigidly for drilling or milling, using the second rod for a counterweight or guide.
Emergency Safety Stop
Holds the load securely in place anywhere along the travel when compressed air supply suddenly fails.
Is the Airtac BSAID Clamp Cylinder BSAID50X160S the Right Clamp-Lock?
Choose this double-rod model when you need equal push/pull force (825 N both ways) and dual-side anti-rotation support. If your application only requires a standard single-rod lock, the BSAI50X160-S offers the same 1400 N hold without the second rod. This BSAID variant excels over a stroke-end-only SAIL cylinder because it grips anywhere along the travel. If you need a higher hold, stepping up to bore 63 provides a 2200 N holding force and 1402 N pull thrust.
For replacement, match the 50 mm bore, 160 mm stroke, PT port threads, and the double-rod layout. The correct mounting set for BSAID omits FB, CA, CB, and CR, accepting only Basic, FA, LB, TC, TCM1, and TCM2. The -S magnet works with AirTAC CMSE (reed) and DMSE (electronic) sensors. Always ensure the rod has stopped before clamping, and add an independent safety measure for human-safety-critical loads.
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 BSAID50X160S FAQ
It provides a static holding force of 1400 N. The clamp-lock engages at any position along the 160 mm stroke, holding the load securely without needing live air pressure.
The clamp locks only after the cylinder has stopped; it cannot brake a moving rod. To unlock safely, air pressure on both sides of the piston must be balanced, otherwise the rod may jump. An independent safety measure is required for human-safety-critical applications.
