Airtac BSE Clamp Standard Cylinder BSE32X900S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE32X900S 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 BSE32X900S
The AirTAC BSE32X900S is a double-acting single-rod ISO 15552 profile cylinder equipped with an integrated spring-applied, air-released rod lock. Because the 900 mm stroke exceeds the 700 mm standard maximum, this unit is provided as a made-to-order configuration. The lock uses a clamping collet that grips the 12 mm piston rod, delivering a bidirectional static holding force of 600 N with zero live air required.
Operating pressure for both the cylinder drive and the lock release is capped at 0.7 MPa. The lock unlocks via a separate G1/8 port, completely independent from the PT1/8 cylinder drive ports. Because this variant includes the -S magnet option, it supports position sensing using CMSE reed or DMSE electronic sensors. Remember that the lock is a holding device, not a dynamic brake; it must only engage after the rod has fully stopped.
Rod Lock — 600 N Static Holding (Ø32mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE32X900S 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.

Where the Airtac BSE Clamp Standard Cylinder BSE32X900S Is Used
Z-Axis Elevator Hold
Keeps a light vertical lift elevator stationary at 900 mm extension, relying on the 600 N fail-safe collet to prevent uncommanded drops if the supply air drops out.
Pallet Stop Gate
Acts as an extended-reach stop gate on a conveyor line, locking rigidly in place during an E-stop event to secure pallets without needing continuous air pressure.
Tooling Position Lock
Holds an extended lightweight machining probe or tooling head firmly in position, engaging the collet only after the 32 mm bore cylinder has fully stopped moving.
Is the Airtac BSE Clamp Standard Cylinder BSE32X900S the Right Cylinder?
Verify your suspended load requires 600 N or less of holding force. If you need less drive power, the BSE series does not offer a smaller bore, so this 32 mm bore (402 N push at 0.5 MPa) is your baseline. 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 static holding force. To release the lock safely, balance pressures on both sides of the piston and allow at least 0.5 s before commanding motion. When replacing, match the 32 mm bore, 900 mm stroke, PT thread, and -S magnet. Because the stroke is 900 mm, ensure external guide rails are used to prevent excessive side-loading on the rod.
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 BSE32X900S FAQ
If air is lost or exhausted, the spring-applied collet immediately clamps the rod, providing a 600 N static holding force in both directions. The drive force is separate: 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, with a maximum drive of 57 kgf.
You must first balance the air pressure on both sides of the piston. Then supply 0.15-0.7 MPa to the separate G1/8 release port. Wait at least 0.5 seconds for the collet to fully disengage before commanding the cylinder to move.
