Airtac BSE Clamp Standard Cylinder BSE32X50S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE32X50S 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, 50mm stroke, PT1/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE32X50S
The AirTAC BSE32X50S is a double-acting, single-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the Ø12 mm piston rod automatically, providing a bidirectional fail-safe holding force of 600 N with no live air required. Operating pressure is capped at 0.7 MPa, and the lock uses a separate G1/8 release port.
Because it uses the standard SE extruded aluminum body, all SE mounting accessories fit the BSE except the FTC variant. The -S option includes a magnet for position sensing with CMSE reed or DMSE electronic sensors. The lock is a static holding device, not a dynamic brake; it must only be engaged after the rod stops completely.
Rod Lock — 600 N Static Holding (Ø32mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE32X50S 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 BSE32X50S Is Used
Small Vertical Lift
Holds a 402 N lifted assembly in place with 600 N of fail-safe clamping force the moment compressed air is lost.
Pneumatic Tool Clamp
Secures a light machining fixture against vibration using the spring-applied collet during an E-stop event.
Indexing Stop Gate
Keeps a conveyor diverter gate locked mid-stroke with zero live air, preventing drift during line pauses.
Is the Airtac BSE Clamp Standard Cylinder BSE32X50S the Right Cylinder?
Verify your load does not exceed the 600 N static holding force. If you need less drive force, the adjacent smaller bore is not available in this series, so 32 mm is the minimum. If you need stronger holding or drive force, step up to bore 40, which provides 628 N push at 0.5 MPa and 900 N of holding force. Always engage the lock only after the rod stops, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving. When replacing, match the 32 mm bore, 50 mm stroke, PT1/8 port, and the -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 BSE32X50S FAQ
The lock is spring-applied and air-released. If air is lost or exhausted, a collet clamps the rod, providing 600 N of bidirectional static holding force to prevent drift. It is a static hold, not a dynamic brake, so it must only be engaged after the rod has stopped.
At 0.5 MPa, the drive force is 402 N push and 345 N pull. At the 0.7 MPa ceiling, push is 563 N with a max drive of 57 kgf. This drive force is separate from the 600 N static holding force of the lock.
