Airtac BSAID Clamp Cylinder BSAID100X500
The AirTAC Airtac BSAID Clamp Cylinder BSAID100X500 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 BSAID100X500
The AirTAC BSAID100X500 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 static holding force of 5500 N, gripping the rod securely at any position along its 500 mm travel. Because it is a double-rod unit, the thrust is equal in both directions at 3681 N at 0.5 MPa. A crucial design distinction is that this 5500 N holding force is entirely separate from the cylinder's 3681 N thrust; you must size the clamp's holding capacity against your static load, not the pneumatic thrust.
The dual-rod architecture exists so you can mount a workpiece on one end and attach a guide, counterweight, or position flag on the opposite end, providing dual-side guidance and anti-rotation. The clamp mechanism uses a dedicated G1/8 enclasp port—separate from the 1/2 inch cylinder ports—and requires balanced air pressure to unlock safely. Furthermore, the variable air cushions at the stroke ends only decelerate the piston; the mechanical clamp is what actually secures the load.

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 BSAID100X500 Is Used
Vertical Lift Holding
Secures heavy vertical loads at any height along the 500 mm travel, preventing gravity-driven drops during air pressure loss.
Machining Position Lock
Clamps a dual-sided workpiece fixture rigidly in place for machining operations, using the second rod for an anti-rotation guide.
Mid-Stroke Safety Stop
Holds a suspended load safely anywhere in the stroke during an emergency stop or power failure, requiring balanced pressure to release.
Is the Airtac BSAID Clamp Cylinder BSAID100X500 the Right Clamp-Lock?
Choose this 100 mm bore model when an application demands substantial equal-force movement in both directions combined with mid-stroke holding. If you need less holding capacity, the 80 mm bore offers 2268 N pull thrust and a 3600 N clamp hold; stepping up to the 125 mm bore yields 5734 N pull thrust and an 8600 N hold. This BSAID100X500 outperforms a stroke-end-only SAIL lock because it grips anywhere along the travel, whereas a plain SAID suffices if no intermediate locking is required. The clamp engages only after the rod stops, so it cannot brake a moving load, and releasing it requires balanced pressures to prevent the rod from jumping abruptly. For safety-critical human-adjacent operations, add an independent safety measure.
As a replacement, verify the double-rod configuration, 100 mm bore, 500 mm stroke, and PT port threads. The 25 mm rod and M20x1.5 thread provide excellent rigidity and side-load resistance, but at 500 mm stroke you should still use an external guide to support the rod. The BSAID mounting set omits the FB, CA, CB, and CR foot and clevis options, accepting only Basic, FA, LB, TC, TCM1, and TCM2 brackets. If position sensing is needed, add the -S magnet for CMSE reed or DMSE electronic sensors.
Quick checklist
- ✓ Hold needed at any position?
- ✓ Or stroke-end only → use SAIL
- ✓ Holding force ≥ your load

Airtac BSAID Clamp Cylinder BSAID100X500 FAQ
The integrated clamp-lock provides a static holding force of 5500 N. It grips the double-rod at any position along the 500 mm stroke, but only engages after the cylinder has stopped moving; it cannot brake a moving rod.
The clamp is spring-applied and air-released via a dedicated G1/8 port. To prevent the rod from jumping abruptly upon release, the air pressures on both sides of the piston must be balanced and the cylinder must be stopped before unlocking.
