Airtac BSAID Clamp Cylinder BSAID50X200
The AirTAC Airtac BSAID Clamp Cylinder BSAID50X200 is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 200mm 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 BSAID50X200
The AirTAC BSAID50X200 is a double-acting ISO 15552 profile cylinder featuring a double-rod configuration and a spring-applied, air-released clamp-lock mechanism. It delivers an equal thrust of 825N in both push and pull directions at 0.5 MPa, while the integrated enclasp gripper provides a static holding force of 1400N. It is crucial to distinguish holding force from thrust: the clamp's 1400N rating secures the static load, whereas the 825N thrust drives the motion. You must size the holding capacity against the load weight, not the cylinder's propulsion strength.
This bidirectional clamp locks the 20mm carbon steel rod at any position along its 200mm stroke, but it only engages after the rod has completely stopped, as it cannot brake a moving load. A third G1/8 enclasp port controls the release, requiring balanced air pressure on both piston sides to prevent the rod from jumping abruptly upon unlocking. The double-rod design allows mounting a workpiece on one end and a guide, counterweight, or position flag on the opposite end for dual-side anti-rotation guidance.

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 BSAID50X200 Is Used
Mid-Stroke Vertical Hold
Suspends a vertical load at any point in the 200mm travel, relying on the 1400N clamp rather than live air pressure to prevent dropping.
Power-Loss Safety Lock
Engages instantly upon air loss to freeze the double-rod position mid-cycle, protecting the workpiece and operators from sudden crashes.
Machining Position Fixture
Uses the dual rods to support a workpiece on one end and a counterweight on the other, locking securely for stable intermediate inspection.
Is the Airtac BSAID Clamp Cylinder BSAID50X200 the Right Clamp-Lock?
Choose this double-rod model when equal force and dual-side mounting are required, stepping down to a 40mm bore (528N thrust, 900N hold) for lighter loads or up to a 63mm bore (1402N pull, 2200N hold) for heavier vertical lifting. The BSAID50X200 outperforms a stroke-end-only SAIL lock by holding the load anywhere in the travel, whereas a plain SAID lacks a lock entirely. Remember that the clamp locks only after the cylinder stops, and safety-critical applications require an additional independent safety measure.
For a direct replacement, match the double-rod layout, 50mm bore, 200mm stroke, and PT port threads. The BSAID mounting set omits FB, CA, CB, and CR brackets, accepting only Basic, FA, LB, TC, TCM1, and TCM2. The variable air cushion decelerates the piston near stroke ends but does not hold the load. Without a specified magnet, this unit does not support 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 BSAID50X200 FAQ
The BSAID50X200 provides a static holding force of 1400N. Its spring-applied clamp locks the rod at any position along the 200mm stroke, holding bidirectionally whether the rod was extending or retracting.
The clamp cannot brake a moving rod; it only locks after the cylinder has stopped. To release it safely, air pressure must be balanced on both sides of the piston via the G1/8 enclasp port, otherwise the rod may jump abruptly upon unlocking.
