Airtac BSAID Clamp Cylinder BSAID63X160S
The AirTAC Airtac BSAID Clamp Cylinder BSAID63X160S is a genuine double-acting ISO 15552 cylinder with a Ø63mm 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 2200 N.

About the Airtac BSAID Clamp Cylinder BSAID63X160S
The AirTAC BSAID63X160-S is a double-acting ISO 15552 profile cylinder featuring a double-rod configuration and a built-in clamp-lock mechanism. A spring-applied, air-released enclasp gripper secures the piston rod at any position along its 160 mm travel, delivering a static holding force of 2200 N. Because it is a double-rod design, the thrust is equal in both directions at 1402 N (0.5 MPa), and the second rod allows you to mount a position flag, counterweight, or secondary tool on the opposite end for dual-side guidance.
It is vital to distinguish this 2200 N static holding force from the 1402 N cylinder thrust: you must size the clamp against the static load, not the pneumatic push force. The lock engages via a dedicated G1/8 enclasp port and holds bidirectionally, but it only activates after the rod has stopped moving—it cannot brake a dynamic load. Furthermore, the variable air cushions at stroke ends only decelerate the piston; they do not hold the load. The clamp requires balanced air pressure to unlock safely, preventing the rod from jumping abruptly upon release.

How the Clamp-Lock Holds
static holding force (Ø63 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa (max) | 2182 N | — |
Equal force both directions (double rod). Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (2200 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAID Clamp Cylinder BSAID63X160S Is Used
Mid-Stroke Vertical Hold
Locks a vertical lift at any height with 2200 N of holding force, preventing gravity-driven drops during air pressure loss without relying on end-stops.
Machining Position Lock
Secures a dual-sided workpiece fixture rigidly in place for machining or inspection, using the second rod for an external guide or counterweight.
Emergency Power-Loss Hold
The spring-applied clamp engages automatically when air is lost, freezing the load exactly where it stopped along the 160 mm travel.
Is the Airtac BSAID Clamp Cylinder BSAID63X160S the Right Clamp-Lock?
Choose this double-rod clamp-lock cylinder when a process requires equal force extending and retracting, plus multi-axis stability or an external attachment point. If the application only needs end-of-stroke holding, a plain SAIL or SAID cylinder suffices. If locking mid-stroke is unnecessary, a standard SAI avoids the extra enclasp plumbing. Stepping down to a 50 mm bore drops the holding force to 1400 N and thrust to 825 N, while stepping up to an 80 mm bore increases the hold to 3600 N and thrust to 2268 N.
This model features a PT tapered port thread, a 20 mm rod with an M16x1.5 thread, and includes the -S magnet for precise position sensing with AirTAC CMSE (reed) or DMSE (electronic) switches. It accepts Basic, FA, LB, TC, TCM1, and TCM2 mounts (omitting FB, CA, CB, and CR). Always ensure the cylinder has stopped and pressures are balanced before unlocking. For safety-critical human loads, add an independent mechanical safety measure.
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 BSAID63X160S FAQ
The clamp provides a static holding force of 2200 N at any position. However, it is not a brake; it only locks after the rod has completely stopped moving. It cannot decelerate a dynamic load.
The double-rod design provides equal thrust (1402 N at 0.5 MPa) in both directions and allows you to mount a workpiece on one end and a guide, counterweight, or position flag on the other for anti-rotation.
