About the Airtac BSAID Clamp Cylinder BSAID100X200
The AirTAC BSAID100X200 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 gripper secures the piston rod at any position along its 200 mm travel, delivering a static holding force of 5500 N. Because it is a double-rod design, the thrust is equal in both directions at 3681 N at 0.5 MPa. Buyers must distinguish this holding force from the thrust: the clamp's 5500 N resists a static load, whereas thrust is the pneumatic drive force.
This model features a 25 mm carbon steel rod with an M20x1.5 thread on both ends. The double-rod layout allows mounting a workpiece on one end and a guide or counterweight on the other for dual-side anti-rotation. The clamp uses a third G1/8 enclasp port alongside the two 1/2 inch PT cylinder ports. Note that the variable air cushion only decelerates the piston near stroke end; the clamp itself provides the actual holding power.

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 BSAID100X200 Is Used
Mid-Stroke Vertical Hold
Suspends heavy vertical loads securely at any point in the travel without relying on continuous air pressure.
Power-Loss Safety Lock
Engages automatically upon air pressure loss to freeze the load exactly where it stopped, preventing sudden drops.
Machining Position Hold
Locks the dual rods rigidly during secondary machining or inspection processes to prevent unwanted deflection.
Is the Airtac BSAID Clamp Cylinder BSAID100X200 the Right Clamp-Lock?
Choose this double-rod clamp-lock cylinder when you need to hold a load securely at an intermediate position and require equal force in both directions. If 3681 N thrust is excessive, step down to the 80 mm bore, which offers 2268 N thrust and a 3600 N holding force. Conversely, if the 5500 N clamp capacity is insufficient, the 125 mm bore provides 8600 N holding force. Choose BSAID over a stroke-end-only SAIL lock when intermediate holding is required, or select a plain SAID if no clamping is needed.
The clamp locks only after the rod has stopped; it cannot brake a moving rod. It must be unlocked with balanced air pressures on both sides of the piston to prevent the rod from jumping abruptly. For safety-critical applications, an independent external safety measure is required. This cylinder accepts Basic, FA, LB, TC, TCM1, and TCM2 mounts (omitting FB/CA/CB/CR). It operates at 0.15-0.7 MPa, uses PT ports, and supports speeds of 30-500 mm/s. As no magnet is specified, it will not work with CMSE or DMSE sensors without modification.
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 BSAID100X200 FAQ
The BSAID100X200 provides a static holding force of 5500 N. The spring-applied clamp locks the rod at any position bidirectionally, but only after the cylinder has stopped moving.
The clamp is released via the G1/8 enclasp port, but only when the air pressures on both sides of the piston are balanced. Releasing it with unbalanced pressure can cause the rod to jump abruptly.
