Airtac BSE Clamp Standard Cylinder BSE32X225S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE32X225S 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, 225mm stroke, PT1/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE32X225S
The AirTAC BSE32X225S is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the Ø12 mm piston rod automatically, delivering a 600 N bidirectional static holding force with zero live air required. This fail-safe mechanism ensures the rod stays exactly where it stopped if air pressure drops or an E-stop is triggered.
Operating pressure for both the cylinder and the separate G1/8 release port is capped at 0.15-0.7 MPa. The lock is a holding device, not a dynamic brake; it must only be engaged after the rod stops, and released only when piston pressures are balanced. This 32 mm bore unit includes a magnet for CMSE reed and DMSE electronic sensors, and runs at speeds of 30-800 mm/s.
Rod Lock — 600 N Static Holding (Ø32mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE32X225S 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 BSE32X225S Is Used
Vertical Pneumatic Lifts
Holds a 60 kg vertical workpiece elevator securely in mid-travel with 600 N of fail-safe force, preventing a sudden drop if the main air supply is exhausted.
Tooling Clamp Hold
Maintains clamping pressure on a machined part during an air pressure loss, keeping the 402 N drive force applied and locking the rod instantly to prevent part ejection.
Pallet Stop Gate
Secures a raised conveyor stop gate during an emergency stop, using the spring-applied collet to lock the 12 mm rod and hold the pallet queue firmly in place.
Is the Airtac BSE Clamp Standard Cylinder BSE32X225S the Right Cylinder?
Verify your suspended load does not exceed the 600 N holding force. If you need less drive force, the next size down does not exist for BSE, so this is the smallest available bore. If you need more holding or drive power, step up to the 40 mm bore, which provides 628 N push at 0.5 MPa and a 900 N static hold. Always engage the lock only after the rod stops, and allow at least 0.5 s for full release before resuming motion. To replace this unit, match the 32 mm bore, 225 mm stroke, PT1/8 port, basic mounting, and the -S magnet option. Since the stroke is 225 mm, ensure adequate guide support to prevent excessive side loads on the rod and collet lock.
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 BSE32X225S FAQ
The lock is spring-applied, engaging a collet to provide a 600 N static holding force in both directions if air is lost. The drive forces are 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, with a max drive of 57 kgf, which is separate from the holding force.
You must supply 0.15-0.7 MPa to the separate G1/8 release port only after the pressures on both sides of the piston are balanced. Allow at least 0.5 seconds for the collet to fully release before commanding the cylinder to move.
