About the Airtac BSAID Clamp Cylinder BSAID63X175S
The AirTAC BSAID63X175-S is a double-acting ISO 15552 profile cylinder featuring a double-rod layout and a spring-applied, air-released clamp-lock. It provides a static holding force of 2200 N, gripping the rod securely at any position along its 175 mm travel. Because it is a double-rod enclasp unit, the thrust is symmetrical, delivering 1402 N of force in both the extend and retract directions at 0.5 MPa. Buyers must distinguish between this holding force and the cylinder thrust: the 2200 N clamp resists an external static load, whereas the 1402 N thrust dictates the pneumatic moving capability.
The dual-rod architecture serves a specific mechanical purpose beyond equal force, allowing you to mount a workpiece on one end and a guide, counterweight, or position flag on the opposite end for dual-side anti-rotation. Furthermore, the variable air cushion only decelerates the piston near the stroke ends; it is the mechanical clamp that actually secures the load. The lock engages strictly after the cylinder has stopped moving, meaning it cannot brake a rod in motion. Unlocking requires a balanced air pressure of 0.15-0.7 MPa applied via the dedicated G1/8 enclasp port, or the rod may jump 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 BSAID63X175S Is Used
Vertical Axis Mid-Stroke Holding
Locks a lifting platform securely at any intermediate height with 2200 N of holding force, preventing gravity-driven drops during operation.
Power Loss Emergency Stop
The spring-applied clamp engages automatically if air pressure drops, freezing the double-rod payload exactly where it stopped.
Machining & Inspection Positioning
Holds a dual-sided workpiece or fixture rigidly in place for precise milling or measurement, utilizing the anti-rotation benefit of the second rod.
Is the Airtac BSAID Clamp Cylinder BSAID63X175S the Right Clamp-Lock?
Step down to a bore 50 if your load requires less holding power, offering 1400 N clamp force and 825 N pull thrust at 0.5 MPa; step up to a bore 80 for heavier rigs, which provides 3600 N holding force and 2268 N thrust. Choose this BSAID model over a stroke-end-only SAIL when you must freeze the load mid-travel rather than solely at the extremes. A plain SAID is sufficient if your process only needs standard dual-rod motion without any intermediate holding. Because the clamp locks only after the rod stops and releases via balanced pressure, human-safety applications require an independent external safety measure.
This specific configuration features a carbon steel rod, PT tapered port threads, and a -S magnet for precise detection with AirTAC CMSE reed and DMSE solid-state sensors. The double-rod mounting interface accepts Basic, FA, LB, TC, TCM1, and TCM2 brackets, deliberately omitting FB, CA, CB, and CR to accommodate the dual-sided rod geometry. The 20 mm rod diameter and M16x1.5 thread provide robust side-load capacity, though any stroke reaching 300 mm or more still requires 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 BSAID63X175S FAQ
The BSAID63X175-S provides a static holding force of 2200 N. The spring-applied clamp locks the rod at any position bidirectionally, but it only engages after the cylinder has completely stopped; it cannot brake a moving rod.
The clamp is released by applying balanced air pressure of 0.15-0.7 MPa to the G1/8 enclasp port. If pressures are not balanced, the rod may jump. The BSAID double-rod design provides equal thrust both ways and allows dual-side mounting, whereas the BSAI has a single rod.
