Airtac BSAID Clamp Cylinder BSAID63X500
The AirTAC Airtac BSAID Clamp Cylinder BSAID63X500 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.

About the Airtac BSAID Clamp Cylinder BSAID63X500
The AirTAC BSAID63X500 is a double-acting ISO 15552 profile cylinder featuring a rod out both ends and a built-in clamp-lock mechanism. A spring-applied, air-released gripper clamps the piston rod to hold the load at any position along the 500 mm stroke, delivering a static holding force of 2200 N. Because it is a double-rod design, the thrust is equal in both directions at 1402 N (0.5 MPa), and the second rod allows you to mount a workpiece on one end while attaching a guide, counterweight, or position flag on the opposite end for dual-side anti-rotation.
It is vital to distinguish the clamp holding force from the cylinder thrust: the 2200 N holding force resists the static load, while the 1402 N thrust drives the movement. The variable air cushion only decelerates the piston near the stroke ends; the clamp is what actually secures the load. This mechanism requires a third G1/8 enclasp port to release the lock, and it operates on a balanced-pressure unlock system to prevent the rod from jumping abruptly upon release.

How the Clamp-Lock Holds
static holding force (Ø63 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 (Ø63mm)
| 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.
Where the Airtac BSAID Clamp Cylinder BSAID63X500 Is Used
Vertical Load Holding
Secures a 63 mm bore vertical axis at any point in its 500 mm travel with 2200 N of holding force, preventing gravity-driven drops when air pressure is removed.
Power Loss Safety
The spring-applied clamp engages automatically on air loss, safely freezing the double-rod position mid-stroke to protect operators and tooling.
Machining Position Lock
Holds a workpiece or fixture rigidly in place during drilling or inspection, using the second rod for a position flag or external guide.
Is the Airtac BSAID Clamp Cylinder BSAID63X500 the Right Clamp-Lock?
Choose this double-rod clamp-lock cylinder when an application requires equal push and pull forces along with multi-sided mounting or anti-rotation guidance. If you do not need a rod on both ends, the single-rod BSAI63X500 offers the same 2200 N holding capacity. If you only need to hold a load at the stroke ends rather than anywhere in travel, a plain SAID63 cylinder without a clamp-lock will suffice. For higher load-holding requirements, stepping up to the 80 mm bore provides a 3600 N holding force and 2268 N pull thrust.
The clamp locks only after the cylinder has stopped; it cannot brake a moving rod. Safety-critical loads require an additional independent safety measure. To replace this unit, match the 63 mm bore, 500 mm stroke, PT tapered ports (3/8 cylinder, G1/8 enclasp), and the BSAID mounting set (Basic, FA, LB, TC, TCM1, TCM2). For a 500 mm stroke, the M16x1.5 rod thread handles side loads well, but an external guide is recommended to prevent binding over the long unsupported travel.
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 BSAID63X500 FAQ
The integrated clamp-lock provides a static holding force of 2200 N. It clamps the rod bidirectionally at any position along the 500 mm stroke, but it only engages after the cylinder has completely stopped moving.
The clamp is released by supplying air to the G1/8 enclasp port, but only after the air pressures on both sides of the piston are balanced. If pressures are not balanced, the rod can jump abruptly upon release.
