Airtac BSE Clamp Standard Cylinder BSE32X900
The AirTAC Airtac BSE Clamp Standard Cylinder BSE32X900 is a genuine double-acting ISO 15552 cylinder with an integrated spring-applied, air-released ROD LOCK. If air is cut or an E-stop is hit, the collet clamps the Ø12mm rod and holds up to 600 N in either direction — no drift. Ø32mm bore, 900mm stroke, PT1/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE32X900
The AirTAC BSE32X900 is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the 12 mm piston rod, providing a bidirectional static holding force of 600 N. If air pressure drops or an E-stop trips, the lock engages automatically to secure the load in place without requiring live air.
Operating pressure is capped at 0.7 MPa, and the separate G1/8 release port requires 0.15-0.7 MPa to unlock the collet. This 900 mm stroke unit is a non-standard made-to-order configuration exceeding the 700 mm standard maximum. Because this SKU lacks the -S magnet option, it does not support CMSE or DMSE position sensors.
Rod Lock — 600 N Static Holding (Ø32mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE32X900 holds its position in both directions when air is lost, exhausted or an E-stop trips. Apply 0.15–0.7 MPa to the G1/8 release port to unlock. Engage the lock only after the rod has stopped (it is not a dynamic brake), and release only when the pressures on both sides of the piston are balanced. Allow at least 0.5 s for full release before moving.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa (max) | 563 N | — |
| Max drive (@0.7 MPa) | 57 kgf | |
Drive force is separate from the 600 N static holding force of the lock. BSE operates up to 0.7 MPa. Size with a safety margin.

Where the Airtac BSE Clamp Standard Cylinder BSE32X900 Is Used
Z-Axis Elevator Hold
Secures a vertical lifting stage on a packaging machine. The 600 N fail-safe collet locks the rod instantly if air is exhausted, preventing the 57 kgf drive load from crashing down.
Tooling Clamp Drift Control
Maintains a clamped machining fixture position during an E-stop. The spring-applied collet holds the load bidirectionally, keeping the tool steady while pneumatic power is removed.
Pallet Stop Gate
Acts as a raised stop gate on a 900 mm conveyor section. The rod lock ensures the gate stays extended and resists impact from pallets when shop air fluctuates.
Is the Airtac BSE Clamp Standard Cylinder BSE32X900 the Right Cylinder?
Verify your load requires a holding force of 600 N or less, and a drive force of 402 N push at 0.5 MPa. If you need less holding capacity, a smaller bore is unavailable in this series (32 mm is the minimum). If your load exceeds the 600 N hold, step up to the 40 mm bore, which provides 628 N push at 0.5 MPa and a 900 N holding force. Remember to engage the lock only after the rod has completely stopped, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving.
At 900 mm, this long stroke demands a guide to prevent excessive side-loading on the rod and front cap. When ordering a replacement, match the 32 mm bore, 900 mm stroke, PT1/8 cylinder port, and basic mounting. SE-compatible mounting accessories fit this body, except FTC.
Quick checklist
- ✓ Load to hold ≤ 600 N?
- ✓ Fail-safe hold on air loss / E-stop needed
- ✓ Lock engaged only when stopped
- ✓ G1/8 release-air line available
- ✓ Magnet (-S) for CMSE/DMSE sensors?
Installation & Safety Notes
- check Engage the lock only after the rod has stopped — not as a dynamic brake.
- check Release only when both piston sides are pressure-balanced.
- check Allow ≥0.5 s for full release before commanding motion.
- check Feed the G1/8 release port with 0.15–0.7 MPa clean air.
- check Add safety-rated controls for man-rated / overhead loads.
- check Use SE mounting accessories (FTC excepted).
Airtac BSE Clamp Standard Cylinder BSE32X900 FAQ
The lock is spring-applied and air-released. If air is lost or exhausted, a collet clamps the 12 mm rod to provide a 600 N bidirectional static hold with no live air. It is not a dynamic brake; you must engage it only after the rod stops.
At 0.5 MPa, the drive force is 402 N push and 345 N pull. At the 0.7 MPa maximum operating pressure, push is 563 N, yielding a 57 kgf max drive. The separate static holding force from the rod lock is 600 N.
