About the Airtac BSAID Clamp Cylinder BSAID63X225S
The AirTAC BSAID63X225-S is a double-acting ISO 15552 profile cylinder featuring a double-rod configuration and a built-in spring-applied, air-released clamp-lock. It delivers a bidirectional thrust of 1402 N at 0.5 MPa, ensuring equal force whether extending or retracting. A defining feature is its ability to lock the piston rod at any position along the 225 mm stroke, providing a static holding force of 2200 N. It is crucial to distinguish this holding force from the cylinder thrust; the 2200 N clamp rating is the measure of the load it can statically resist, independent of the 1402 N dynamic thrust used for movement.
Because it is a double-rod design, the BSAID63X225-S allows workpieces to be mounted on one rod end while a guide, counterweight, or position flag attaches to the opposite end, providing dual-side guidance and anti-rotation benefits. The lock engages only after the rod has stopped, meaning it cannot brake a moving load. Unlocking requires balanced air pressure on both sides of the piston via the dedicated G1/8 enclasp port; failing to balance the pressure before releasing the clamp can cause abrupt rod movement. The variable air cushions at stroke ends only decelerate the piston and do not contribute to holding the load.

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 BSAID63X225S Is Used
Vertical Load Holding
Locks a lifted workpiece securely at any intermediate height on vertical axes, preventing gravity-driven drops during air pressure loss.
Power Failure Safety
Spring-applied clamp immediately engages to freeze the double-rod position anywhere in the travel if the air supply drops, securing the zone.
Machining Position Lock
Holds the part rigidly at a specific non-end stroke coordinate for precise milling or inspection, resisting cutting forces with 2200 N.
Is the Airtac BSAID Clamp Cylinder BSAID63X225S the Right Clamp-Lock?
Choose this double-rod clamp-lock model when an application demands equal force in both directions alongside multi-position holding. If your load requires less holding capacity, stepping down to a 50 mm bore provides a 1400 N clamp force and 825 N bidirectional thrust. If you only need to hold the load at the stroke ends rather than anywhere in transit, a SAIL cylinder is a simpler choice, while a plain SAID lacks a lock entirely. For any replacement, verify the 3/8 cylinder ports, PT thread type, and note that BSAID mounting omits the FB, CA, CB, and CR options, supporting Basic, FA, LB, TC, TCM1, and TCM2 brackets.
The integrated -S magnet supports AirTAC CMSE reed and DMSE electronic sensors for position feedback. Remember that the clamp locks only after the cylinder stops and must be released with balanced pressures to prevent sudden rod jumps. For safety-critical loads, an independent external safety measure is required. The 20 mm rod diameter and M16x1.5 thread provide robust side-load capacity, though external guidance is recommended for this 225 mm stroke if heavy eccentric loads are present.
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 BSAID63X225S FAQ
This cylinder provides a static holding force of 2200 N. Unlike stroke-end locks, the enclasp mechanism clamps the rod securely at any position along the 225 mm travel, holding bidirectionally once the rod has stopped.
The clamp unlocks only when air pressure is balanced on both sides of the piston via the G1/8 enclasp port. If pressures are not balanced, the rod can jump abruptly upon release, so always ensure the cylinder has stopped and pressures are equalized.
