The AirTAC Airtac BSAID Clamp Cylinder BSAID63X500S is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 500mm 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 2200 N.
The AirTAC BSAID63X500-S is a double-acting ISO 15552 profile cylinder featuring a double-rod layout and a built-in spring-applied, air-released clamp-lock. It secures the load at any position along its 500mm stroke, delivering a static holding force of 2200 N. Because it is a double-rod unit, its thrust is equal in both directions, providing 1402 N of push and pull force at 0.5 MPa. It is essential to distinguish this holding force from thrust: the 2200 N clamp rating dictates how much static load the rod can freeze in place, whereas the 1402 N thrust dictates what it can move dynamically.
This enclasp mechanism requires a third G1/8 pneumatic port to release the grip, operating within a 0.15-0.7 MPa pressure range. The double-rod design is specifically chosen to mount a workpiece on one end while attaching a guide, counterweight, or position flag on the opposite end, yielding dual-side guidance and anti-rotation benefits. Furthermore, the variable air cushions at the stroke ends only decelerate the piston; they do not hold the load. The clamp itself locks the rod bidirectionally, but only after the cylinder has come to a complete stop.

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 | 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.
Locks a 63mm double-rod lift axis at any intermediate height during a process cycle, preventing gravity-driven drops without relying on continuous air pressure.
The spring-applied clamp instantly engages upon loss of air pressure, freezing the dual rods in place anywhere along the 500mm stroke to secure the workpiece.
Holds a part rigidly for secondary operations while the opposing rod end mounts a position flag or guide, ensuring anti-rotation and high positional accuracy.
Select this double-rod model when an application requires equal force both ways and multi-sided tool mounting alongside mid-stroke holding. If your dynamic load demands higher thrust, stepping up to a bore 80 yields 2268 N of thrust at 0.5 MPa and a 3600 N holding force. Conversely, a bore 50 provides 825 N thrust and 1400 N holding force for lighter setups. Choose this BSAID over a stroke-end-only SAIL cylinder when you must freeze the rod anywhere in the travel, and select a plain SAID when no mid-stroke holding is required at all.
As a replacement, verify the double-rod format, 63mm bore, 500mm stroke, PT port threads, and the -S magnet for CMSE reed and DMSE electronic sensors. The mounting footprint accepts Basic, FA, LB, TC, TCM1, and TCM2 brackets, omitting FB, CA, CB, and CR. Because the stroke is 500mm, an external guide is recommended to support the rod and prevent excessive side-loading. Always note that the clamp locks only after the rod stops, and it must be unlocked with balanced pressures on both sides of the piston to prevent the rod from jumping abruptly. For human-safety-critical holds, add an independent mechanical safety measure.
Quick checklist
The spring-applied clamp-lock provides a static holding force of 2200 N. It engages bidirectionally at any position along the 500mm stroke, but it only locks after the rod has stopped moving, meaning it cannot act as a brake for a moving load.
The clamp is released via a third G1/8 port, but only after the air pressures on both sides of the piston are balanced to prevent the rod from jumping. Unlike a SAIL cylinder that only holds at stroke ends, this BSAID locks anywhere along the travel and uses a double-rod layout for equal push/pull force and dual-side mounting.
