Airtac BSAID Clamp Cylinder BSAID100X500S
The AirTAC Airtac BSAID Clamp Cylinder BSAID100X500S is a genuine double-acting ISO 15552 cylinder with a Ø100mm 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 5500 N.

About the Airtac BSAID Clamp Cylinder BSAID100X500S
The AirTAC BSAID100X500-S is a double-acting ISO 15552 profile cylinder featuring a double-rod layout and an integrated spring-applied, air-released clamp-lock. It provides a robust static holding force of 5500 N, gripping the rod securely at any position along its travel. Because it is a double-rod variant, the thrust is identical in both directions at 3681 N (at 0.5 MPa), and the protruding rod at the rear allows engineers to mount a position flag, a secondary guide, or a counterweight for dual-side anti-rotation.
It is vital to distinguish holding force from cylinder thrust: the 5500 N clamp rating is the static load capacity of the brake, entirely separate from the 3681 N pneumatic thrust that moves the load. The clamp uses a dedicated G1/8 enclasp port to release the rod, requiring a balanced air pressure between 0.15 and 0.7 MPa on both piston sides to unlock safely. Furthermore, the variable air cushion at the stroke ends only decelerates the piston; it does not hold the load. The integrated -S magnet pairs directly with AirTAC CMSE reed and DMSE electronic sensors for precise positioning feedback.

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 BSAID100X500S Is Used
Vertical Load Holding
Suspends heavy lifting platforms at any point in the 500mm travel, relying on the 5500 N static clamp to prevent gravity-driven drops during air loss.
Machining Position Lock
Freezes a dual-side workpiece fixture mid-stroke so the opposing tooling can mill or inspect without pneumatic pressure fluctuations shifting the part.
Emergency Safety Stop
Holds the load securely wherever the rod stops upon power failure, acting as a fail-safe clamp while an independent mechanical lock engages for human safety.
Is the Airtac BSAID Clamp Cylinder BSAID100X500S the Right Clamp-Lock?
Choose this 100mm bore model when an application demands high load retention mid-stroke, stepping up from a BSAID80 which offers 3600 N holding force and 2268 N thrust. Step down to BSAID80 if your static load is lighter, but retain the 100mm bore if you need the 3681 N bidirectional thrust to move heavy tooling. The BSAID100X500-S is preferred over a stroke-end-only SAIL cylinder when you must freeze the load anywhere in the 500mm travel, whereas a plain SAID suffices if no中途 clamping is required.
For replacements, verify the double-rod configuration, 500mm stroke, PT port threads, and the -S magnet for CMSE/DMSE switches. The correct mounting set for this double-rod clamp-lock cylinder includes Basic, FA, LB, TC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the stroke is 500mm, the M20x1.5 rod provides good side-load capacity, but an external guide is strongly recommended to prevent binding. Remember: the clamp locks only after the rod stops—it cannot brake a moving load—and safety-critical applications require an independent mechanical backup.
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 BSAID100X500S FAQ
The 5500 N holding force is the static clamping capacity of the spring-applied brake, which is entirely separate from the 3681 N bidirectional pneumatic thrust that moves the load. You must size the holding force against the static weight of the load, not the cylinder thrust.
No, the clamp locks only after the cylinder has stopped; it cannot brake a moving rod. It must be unlocked with balanced air pressure on both sides of the piston, or the rod can jump abruptly. Safety-critical loads require an additional independent safety measure.
