About the Airtac BSAI Locking Clamp Cylinder BSAI63X100S
The AirTAC BSAI63X100-S is a double-acting ISO 15552 profile cylinder equipped with a spring-applied, air-released clamp-lock mechanism. A defining feature of this series is its ability to lock the piston rod at ANY position along its 100 mm stroke, providing a robust static holding force of 2200 N. Unlike the SAIL series, which only secures the load at stroke ends, this enclasp gripper delivers bidirectional holding power whether the rod was extending or retracting. Operating at 0.15-0.7 MPa, it generates 1559 N of push thrust and 1402 N of pull thrust at 0.5 MPa.
It is critical to distinguish between the cylinder's thrust and the clamp's holding force: the 2200 N holding force is a separate static rating sized to support the load, not the pneumatic thrust. The lock engages via a dedicated G1/8 enclasp port, functioning independently from the 3/8 cylinder ports. Furthermore, the adjustable air cushions only decelerate the piston near the stroke ends; the clamp mechanism is the sole device responsible for securing the load in place.

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 | — |
Push/pull as tabulated. 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 BSAI Locking Clamp Cylinder BSAI63X100S Is Used
Vertical Load Holding
Secures elevated workpieces at any point along the vertical axis, preventing gravity-induced drops during power loss with 2200 N of static holding force.
Machining Position Hold
Locks the rod mid-stroke to rigidly freeze a part in place for machining or inspection operations without relying on continuous pneumatic pressure.
Emergency Stop Safety
Holds the load securely anywhere in the travel range during an emergency stop, though an independent safety measure is required for human safety.
Is the Airtac BSAI Locking Clamp Cylinder BSAI63X100S the Right Clamp-Lock?
Choose this 63 mm bore when an application demands mid-stroke positioning with a 2200 N static hold, stepping up from the 50 mm bore (1400 N holding force, 982 N push thrust at 0.5 MPa) for heavier vertical loads. If the load only needs securing at the fully extended or retracted end, a plain SAIL or SAI cylinder suffices. For replacement, verify the 100 mm stroke, PT port threads, single rod configuration, and the -S magnet option for precise position sensing with AirTAC CMSE (reed) or DMSE (electronic) switches. The M16x1.5 rod thread provides a sturdy mounting interface for moderate side loads.
When integrating this cylinder, remember the clamp locks only AFTER the rod has stopped; it cannot brake a moving load. The enclasp must be released with balanced air pressures on both sides of the piston, or the rod may jump abruptly. For safety-critical applications, an independent external safety measure is required. Mounting options include Basic, FA, FB, CA, CB, CR, 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 BSAI Locking Clamp Cylinder BSAI63X100S FAQ
It uses a spring-applied, air-released mechanism that clamps the rod at any stroke position, providing a 2200 N static holding force. It is bidirectional and engages via a G1/8 enclasp port, but only locks after the cylinder has stopped moving.
The BSAI series locks at ANY position along the stroke, whereas the SAIL series only holds the load at the stroke ends. Additionally, the BSAI clamp must be unlocked with balanced pressures on both sides of the piston to prevent the rod from jumping.
