Airtac BSAID Clamp Cylinder BSAID50X500S
The AirTAC Airtac BSAID Clamp Cylinder BSAID50X500S is a genuine double-acting ISO 15552 cylinder with a Ø50mm 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 1400 N.

About the Airtac BSAID Clamp Cylinder BSAID50X500S
The AirTAC BSAID50X500-S is a double-acting ISO 15552 profile cylinder featuring a double-rod design and a spring-applied, air-released clamp-lock. It provides a static holding force of 1400 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 825 N (0.5 MPa), and the extending rod from both ends allows you to mount a workpiece on one side and a guide or counterweight on the other for dual-side anti-rotation.
It is vital to distinguish this 1400 N holding force from the 825 N thrust; the clamp secures the static load, while thrust drives the motion. The clamp is engaged by a spring and released via a separate G1/8 enclasp port using 0.15-0.7 MPa air. Note that the variable air cushion only decelerates the piston near stroke ends; it does not hold the load. The clamp locks only after the rod stops, and unlocking requires balanced pressure to prevent the rod from jumping abruptly.

How the Clamp-Lock Holds
static holding force (Ø50 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa (max) | 1374 N | — |
Equal force both directions (double rod). Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (1400 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAID Clamp Cylinder BSAID50X500S Is Used
Vertical Mid-Stroke Holding
Suspends elevated platforms or tools securely at any point along the 500 mm vertical travel without relying on continuous air pressure.
Power-Loss Safety Stop
Spring-applied clamp immediately grips the rod when air pressure drops, preventing uncontrolled falls anywhere in the stroke.
Dual-Side Machining Fixture
Uses the double-rod design to mount a workpiece on one end and a position flag on the other, locking the assembly for precise inspection.
Is the Airtac BSAID Clamp Cylinder BSAID50X500S the Right Clamp-Lock?
Choose this double-rod clamp-lock when you need to suspend a load mid-stroke on a vertical axis and require symmetric force. If you only need end-of-stroke holding, a SAIL cylinder suffices, but BSAID locks anywhere. If your load exceeds 1400 N, step up to bore 63, which offers 1402 N thrust and a 2200 N clamp. For lighter loads, bore 40 provides 528 N thrust and 900 N holding force.
This 50 mm bore model uses a PT 1/4 cylinder port alongside the G1/8 unlock port. It accepts Basic, FA, LB, TC, TCM1, and TCM2 mounts (omitting FB/CA/CB/CR due to the double-rod). The -S magnet works with CMSE reed and DMSE electronic sensors. Because the 500 mm stroke is long, an external guide is recommended to manage side loads. Safety-critical applications require an independent backup measure, as the clamp cannot brake a moving rod.
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 BSAID50X500S FAQ
The integrated clamp-lock provides a static holding force of 1400 N. It grips the rod bidirectionally at any position, but only engages after the cylinder has stopped moving.
The clamp is released by applying 0.15-0.7 MPa air to the G1/8 enclasp port, but only after the pressures on both sides of the piston are balanced. If not balanced, the rod can jump abruptly upon release.
