The AirTAC Airtac BSAID Clamp Cylinder BSAID100X175 is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 175mm 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 5500 N.
The AirTAC BSAID100X175 is a double-acting ISO 15552 profile cylinder featuring a double-rod design and a spring-applied, air-released clamp-lock. It provides an equal thrust of 3681 N in both extension and retraction directions at 0.5 MPa. A defining trait of this enclasp mechanism is its capacity to lock the rod at any position along the 175mm travel, delivering a robust static holding force of 5500 N. It is crucial to distinguish this holding force from the cylinder thrust; while thrust moves the load, the clamp is what statically sustains it against gravity or external forces when air pressure is removed.
Because it is a double-rod actuator, one end can mount the workpiece while the opposite end attaches a counterweight, position flag, or secondary tool, providing dual-side guidance and anti-rotation benefits. The enclasp requires a third G1/8 pneumatic port separate from the primary 1/2 inch PT cylinder ports to release the spring-loaded gripper. Remember that the variable air cushions at the stroke ends only decelerate the piston; they do not hold the load. The clamp engages strictly after the rod has stopped moving, meaning it cannot serve as an emergency brake for a dynamic load.

Specifications follow the official AirTAC BSAI datasheet (ISO 15552). Operating pressure is 0.15–0.7 MPa (lower than a plain SAI). Port options: PT / G.
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.
| 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.
Suspends heavy vertical loads anywhere along the 175mm travel using the 5500 N static holding force, preventing gravity-induced drops during cycle pauses.
Secures a dual-sided workpiece or fixture rigidly in place for secondary machining or inspection operations without maintaining live pneumatic pressure.
The spring-applied clamp engages automatically upon air loss, safely freezing the double-rod position to protect processes and operators.
Choose this 100mm bore clamp-lock cylinder when an application requires holding a heavy load mid-stroke, stepping up from a BSAID80 model which offers 2268 N of thrust and 3600 N of holding force. If the load only needs to be secured at the fully extended or retracted end of travel, a plain SAI or SAID cylinder paired with a SAIL stroke-end lock would suffice. However, for position flexibility anywhere in the 175mm travel, this BSAID model is the correct choice. To replace this actuator, match the double-rod configuration, 100mm bore, 175mm stroke, PT port threads, and the 1/2 inch primary cylinder ports. The double-rod mounting set omits FB, CA, CB, and CR brackets, utilizing Basic, FA, LB, TC, TCM1, or TCM2 instead. The standard carbon steel rod features an M20x1.5 thread, providing a sturdy interface for high side-load tolerance. No magnet is specified for this unit, so CMSE or DMSE sensors cannot be used without modification.
For safe operation, ensure the air pressures on both sides of the piston are balanced before unlocking the clamp, otherwise the rod may jump abruptly upon release. Because the clamp locks only after the cylinder has stopped, any safety-critical human load requires an additional independent safety measure.
Quick checklist
The clamp-lock provides a static holding force of 5500 N. It uses a spring-applied, air-released mechanism to grip the rod bidirectionally at any position along the stroke, not just at the ends.
No, the clamp locks only after the cylinder has stopped; it cannot brake a moving rod. Additionally, it must be unlocked with balanced air pressures on both sides of the piston to prevent the rod from jumping. Safety-critical loads require an independent safety measure.
