Airtac BSE Clamp Standard Cylinder BSE125X600
The AirTAC Airtac BSE Clamp Standard Cylinder BSE125X600 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 Ø32mm rod and holds up to 8600 N in either direction — no drift. Ø125mm bore, 600mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE125X600
The AirTAC BSE125X600 is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a massive 8600 N bidirectional static holding force with no live air, ensuring suspended loads remain exactly where they stopped if air pressure drops. Operating pressure is capped at 0.7 MPa, and the lock releases via a dedicated G1/8 port.
This 125 mm bore, 600 mm stroke unit provides 8590 N of push drive force at 0.7 MPa while running at speeds of 30-500 mm/s. Because this SKU lacks the -S magnet option, it does not support CMSE or DMSE position sensors. The lock is a static holding device, not a dynamic brake; it must engage only after the rod stops, with at least 0.5 s allowed for full release before motion resumes.
Rod Lock — 8600 N Static Holding (Ø125mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE125X600 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 BSE125X600 Is Used
Heavy Press Tooling Clamp
Secures large press dies and heavy tooling fixtures. The 8600 N fail-safe collet prevents the 8590 N driven load from slipping downward during an air loss event.
Palletizer Vertical Lift
Holds a fully loaded palletizer lift arm mid-traverse. If E-stop trips, the spring-applied lock clamps the 32 mm rod instantly, preventing a loaded pallet from dropping.
Automated Foundry Gate
Controls a massive foundry cooling gate. The 6136 N pull force at 0.5 MPa retracts the heavy barrier, while the lock holds it rigidly open against mechanical vibration.
Is the Airtac BSE Clamp Standard Cylinder BSE125X600 the Right Cylinder?
Verify your load requires less than the 8600 N static holding force and 8590 N push force at 0.7 MPa. If you need less power, stepping down to the 100 mm bore yields 3927 N push at 0.5 MPa and 5500 N holding force. As the largest standard bore, there is no larger option for higher loads. Always engage the lock only after the rod stops, and release it only when piston pressures are balanced.
For this 600 mm stroke, add external guide rails to prevent side-loading damage to the seal and rod. The cylinder port is PT1/2, the lock-release port is G1/8, and the rod-end thread is M27x2. SE mounting accessories fit this body perfectly, except FTC. To add position detection, select the -S magnet variant for CMSE or DMSE sensors.
Quick checklist
- ✓ Load to hold ≤ 8600 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 BSE125X600 FAQ
The integrated rod lock is spring-applied and air-released, making it fail-safe. If air is lost or exhausted, the collet clamps the 32 mm rod, providing an 8600 N bidirectional static holding force to keep the load in place without live air.
The drive force at 0.5 MPa is 6136 N push and 5734 N pull. At the 0.7 MPa maximum operating pressure, push is 8590 N (max 876 kgf). Separately, the static holding force of the lock is 8600 N.
