About the Airtac BSAI Locking Clamp Cylinder BSAI32X1000
The AirTAC BSAI32X1000 is a double-acting ISO 15552 profile cylinder with a built-in clamp-lock, featuring a 32 mm bore and a 1000 mm stroke. A spring-applied, air-released mechanism grips the carbon steel piston rod to hold the load at any position along its travel, providing a static holding force of 600 N. Because this is a non-standard stroke exceeding the 700 mm maximum for this bore, it is built to order. The cylinder delivers 402 N push thrust at 0.5 MPa (563 N at 0.7 MPa), but remember that holding force and thrust are separate quantities; you must size the 600 N clamp against your static load, not the pneumatic thrust.
The clamp is bidirectional, holding securely whether the rod was extending or retracting. It is activated via a third G1/8 enclasp port, requiring 0.15-0.7 MPa to release. Remember that the variable air cushion only decelerates the piston near stroke ends; the clamp is the device that actually holds the load. The lock engages only after the cylinder has stopped, meaning it cannot brake a moving rod.

How the Clamp-Lock Holds
static holding force (Ø32 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa (max) | 563 N | — |
Push/pull as tabulated. Rated to the 0.7 MPa operating maximum for this series. The clamp holding force (600 N) is separate from cylinder thrust. Size with a margin.
Where the Airtac BSAI Locking Clamp Cylinder BSAI32X1000 Is Used
Vertical Z-Axis Holding
Secures a 1000 mm vertical lift arm at any height to prevent gravity drops during operation or power loss.
Emergency Power Loss Hold
Spring-applied clamp immediately grips the rod to freeze the position anywhere in the 1-meter travel upon air loss.
Mid-Stroke Machining Stop
Locks the rod at a precise intermediate point to rigidly support a workpiece for inspection or drilling.
Is the Airtac BSAI Locking Clamp Cylinder BSAI32X1000 the Right Clamp-Lock?
Choose this 32 mm bore model for long-travel vertical or horizontal axes requiring mid-stroke holding without maintaining live air pressure. If you need more holding capacity, stepping up to a 40 mm bore provides 900 N of holding force and 628 N thrust at 0.5 MPa. If you only need to hold at the stroke end, a plain SAIL lock cylinder is simpler and more economical; BSAI is specifically required when the load must be arrested at any intermediate point. For safety-critical applications, note that the clamp locks only after the rod stops and must be unlocked with balanced pressures to prevent the rod from jumping abruptly.
This BSAI32X1000 uses a PT tapered 1/8 cylinder port alongside the G1/8 enclasp port. It accepts Basic, FA, FB, CA, CB, CR, LB, TC, TCM1, and TCM2 mountings. Because the stroke is 1000 mm on a 12 mm rod, the unsupported length is highly susceptible to side-loading; an external guide rail is strongly recommended to prevent rod binding. A magnet for CMSE reed or DMSE electronic sensors is not included on this standard configuration.
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 BSAI32X1000 FAQ
The built-in clamp-lock provides a static holding force of 600 N. It can hold the load at any position along the 1000 mm stroke, but it only engages after the cylinder has stopped moving; it is not a dynamic brake.
The clamp is released by applying 0.15-0.7 MPa to the G1/8 enclasp port, but only after the air pressures on both sides of the piston are balanced to prevent the rod from jumping. Unlike SAIL which only holds at stroke ends, this BSAI model locks anywhere, requiring careful balanced-pressure unlocking.
