About the Airtac BSAID Clamp Cylinder BSAID100X25S
The AirTAC BSAID100X25-S is a double-acting ISO 15552 profile cylinder featuring a double-rod layout and a spring-applied, air-released clamp-lock. It secures the load at any position along its 25 mm travel, delivering a static holding force of 5500 N. Because it is a double-rod unit, the thrust is equal in both directions at 3681 N (0.5 MPa), while the carbon steel rods extending from both ends allow you to mount a workpiece on one side and a counterweight or position flag on the other.
It is vital to distinguish this 5500 N holding force from the cylinder's 3681 N thrust—the clamp size must match the static load, not the push force. The integrated variable air cushion only decelerates the piston near the stroke ends; the clamp is what actually holds the load. Unlocking requires a separate G1/8 enclasp port and balanced air pressure on both sides to prevent the rod from jumping abruptly. An -S magnet is included for precise position detection via CMSE reed or DMSE electronic sensors.

How the Clamp-Lock Holds
static holding force (Ø100 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa (max) | 5498 N | — |
Equal force both directions (double rod). Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (5500 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAID Clamp Cylinder BSAID100X25S Is Used
Vertical Lift Holding
Maintains vertical load positions anywhere in the 25 mm travel during power loss, relying on the 5500 N clamp rather than live air pressure.
Machining Clamp
Locks a dual-sided workpiece or fixture rigidly in place for precision machining, using the second rod for a position flag.
Safety Emergency Stop
Secures the mechanism at any intermediate point when the system halts, provided the cylinder has fully stopped before locking.
Is the Airtac BSAID Clamp Cylinder BSAID100X25S the Right Clamp-Lock?
Choose this 100 mm bore model when a 50 mm bore (825 N pull, 1400 N hold) lacks the holding capacity for a heavy vertical load. A plain SAID cylinder suffices if you only need equal thrust both ways without intermediate holding, and a SAIL lock limits you to stroke-end holding only. The BSAID100X25-S clamp engages only after the rod stops—it cannot brake a moving load, and safety-critical applications require an independent backup measure.
This replacement double-rod unit has a 25 mm stroke, PT tapered ports (1/2 inch cylinder, G1/8 enclasp), and a 25 mm rod thread (M20x1.5) that handles high side loads. It supports Basic, FA, LB, TC, TCM1, and TCM2 mountings (omitting FB/CA/CB/CR). The short 25 mm stroke avoids sagging, but external guidance is recommended if side loads are applied.
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 BSAID100X25S FAQ
The integrated clamp-lock provides a static holding force of 5500 N. It locks the rod at any position along the stroke, but only after the cylinder has stopped moving.
The clamp is released via a separate G1/8 enclasp port, but only when air pressures on both sides of the piston are balanced. If unbalanced, the rod can jump abruptly upon release.
