Airtac BSE Clamp Standard Cylinder BSE32X25S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE32X25S 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, 25mm stroke, PT1/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE32X25S
The AirTAC BSE32X25S is a double-acting, single-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 600 N bidirectional static holding force with zero live air, ensuring suspended loads stay exactly where they stopped during an E-stop or pressure loss. Operating pressure is capped at 0.7 MPa, and the lock uses a dedicated G1/8 release port.
This 32 mm bore, 25 mm stroke variant includes a magnet for position sensing and uses adjustable air cushions at both ends. The collet lock engages mechanically, meaning the air cushion provides end-of-stroke deceleration but the lock provides the actual holding power. It accepts standard SE mounting accessories, except FTC.
Rod Lock — 600 N Static Holding (Ø32mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE32X25S 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 BSE32X25S Is Used
Small Vertical Lift
Holds a 600 N vertical pick-and-place head mid-stroke. If air exhausts suddenly, the collet locks the 12 mm rod to prevent the tool from dropping.
Tool Clamp Hold
Secures a small pneumatic clamp during machining. The spring-applied collet maintains the 402 N push force position without requiring continuous live air.
Pallet Stop Gate
Acts as a fail-safe stop gate on a 30-800 mm/s conveyor. The lock keeps the gate rigidly extended during E-stops, resisting impacts up to 600 N.
Is the Airtac BSE Clamp Standard Cylinder BSE32X25S the Right Cylinder?
Verify your suspended load requires 600 N or less of holding force. If you need less drive force, the next size down does not exist, so this is the smallest fail-safe option. If you need more capacity, stepping up to a 40 mm bore provides a 628 N push at 0.5 MPa and a 900 N holding force. Always engage the lock only after the rod fully stops, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving. For exact replacement, match the 32 mm bore, 25 mm stroke, PT1/8 cylinder port, and -S magnet option.
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 BSE32X25S FAQ
The lock is spring-applied and air-released. If air is lost or exhausted, a spring forces a clamping collet onto the piston rod, providing a 600 N bidirectional static holding force with no live air. It is not a dynamic brake and must only be engaged after the rod stops.
The drive force is separate from the 600 N holding force. At 0.5 MPa, push is 402 N and pull is 345 N. At the 0.7 MPa ceiling, push is 563 N, yielding a max drive of 57 kgf.
