About the Airtac BSAID Clamp Cylinder BSAID50X600S
The AirTAC BSAID50X600-S is a double-acting ISO 15552 profile cylinder featuring a double-rod configuration and a built-in clamp-lock mechanism. A spring-applied, air-released gripper secures the piston rod at any position along the 600mm stroke, delivering a static holding force of 1400 N. Because it is a double-rod actuator, the thrust is identical in both directions at 825 N (0.5 MPa), and the extending rod from the opposite end allows you to mount a position flag, guide, or secondary tool while providing dual-side anti-rotation support.
It is crucial to distinguish this 1400 N holding force from the 825 N thrust: the clamp sustains static loads without live air pressure, whereas thrust drives the motion. The lock engages only after the rod has completely stopped, meaning it cannot brake a moving load. Furthermore, the clamp releases via a dedicated G1/8 enclasp port and requires balanced air pressures on both piston sides to prevent the rod from jumping abruptly upon unlock.

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 BSAID50X600S Is Used
Vertical Axis Drop Prevention
Holds a 1400 N vertical load at any mid-stroke position during a power loss, preventing gravity-driven falls on lifting stages.
Machining Position Hold
Locks the double-rod firmly in place for secondary machining or inspection, using the opposite rod end for a position flag.
Dual-Tool Assembly Station
Mounts a workpiece on one end and a counterweight or second tool on the other, locking the assembly securely during part transfers.
Is the Airtac BSAID Clamp Cylinder BSAID50X600S the Right Clamp-Lock?
Choose this 50mm bore double-rod model when an application requires equal push/pull force and multi-sided mounting. If your load exceeds 1400 N or you need higher thrust, step up to the 63mm bore, which provides 1402 N pull thrust and a 2200 N holding force. If you only need to secure the load at the stroke extremes rather than mid-stroke, a plain SAIL or SAID cylinder suffices; the BSAID50X600-S is specifically selected for its ability to lock anywhere along the travel.
For safe operation, remember the clamp locks only after the cylinder stops and must be unlocked with balanced pressures. Safety-critical applications require an additional independent safety measure. This configuration includes a magnet for CMSE reed and DMSE electronic sensors. The 20mm carbon steel rod with an M16x1.5 thread handles side loads well, but at 600mm of stroke, an external guide is strongly recommended to prevent rod binding. It accepts PT ports, a 1/4 inch cylinder port, and mountings Basic, FA, LB, TC, TCM1, and TCM2.
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 BSAID50X600S FAQ
The clamp-lock provides a static holding force of 1400 N. It is spring-applied and air-released, meaning it secures the double-rod at any position along the 600mm stroke without requiring continuous air pressure.
The clamp unlocks via a separate G1/8 enclasp port, but only when the air pressures on both sides of the piston are balanced. If pressures are not equalized, the rod can move abruptly upon release. The lock also only engages after the rod has stopped, so it cannot act as a brake.
