Airtac BSE Clamp Standard Cylinder BSE32X400S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE32X400S 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, 400mm stroke, PT1/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE32X400S
The AirTAC BSE32X400S is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the 12 mm piston rod automatically, delivering a 600 N bidirectional static holding force with zero live air. This fail-safe mechanism prevents drift whenever air is exhausted or an E-stop is triggered.
Operating pressure is capped at 0.15-0.7 MPa, and the lock is released via a separate G1/8 port. The lock is a holding device, not a dynamic brake; it must be engaged only after the rod stops, with pressures balanced before unlocking. The -S magnet option supports CMSE reed and DMSE electronic sensors for position feedback.
Rod Lock — 600 N Static Holding (Ø32mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE32X400S 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.

Specifications follow the official AirTAC BSE datasheet. The lock uses the SE standard body; SE mounting accessories fit BSE except FTC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
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 BSE32X400S Is Used
Z-Axis Lift Hold
Secures vertical lift stages on PCB handling machines. The 600 N collet lock engages instantly on air loss, preventing gravity-driven drift of the 402 N drive load.
Tooling Clamp
Maintains clamping force on light pneumatic machining fixtures. If shop air drops below 0.15 MPa, the spring collet holds the tool firmly in position.
Pallet Stop Gate
Acts as a fail-safe stop gate on 32 mm packaging conveyors. The lock keeps the rod extended during E-stops, holding the 563 N max drive load securely.
Is the Airtac BSE Clamp Standard Cylinder BSE32X400S the Right Cylinder?
Verify your suspended load stays strictly under the 600 N holding force. If you need less drive force, the adjacent bore down does not exist for BSE, so 32 mm is the floor. If you need more hold or push, stepping up to bore 40 provides 628 N push at 0.5 MPa and a 900 N holding force. The 402 N push at 0.5 MPa (563 N at 0.7 MPa) must drive your friction load without stalling.
Because the 400 mm stroke exceeds 300 mm, use a guide rail to prevent side-load bending and premature seal wear. Always balance pressures on both piston sides and allow at least 0.5 s for full release before moving. For a drop-in replacement, match the 32 mm bore, 400 mm stroke, PT1/8 cylinder port, and -S magnet. SE 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 BSE32X400S FAQ
The spring-applied collet clamps the rod, providing a 600 N bidirectional static hold with no live air. The drive forces are separate: 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a max drive of 57 kgf.
Supply 0.15-0.7 MPa to the separate G1/8 release port. You must balance the pressures on both sides of the piston first, then allow at least 0.5 s for full release before commanding motion. Never engage the lock while the rod is moving.
