Airtac BSE Clamp Standard Cylinder BSE125X800
The AirTAC Airtac BSE Clamp Standard Cylinder BSE125X800 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, 800mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE125X800
The AirTAC BSE125X800 is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a massive 8600 N bidirectional static holding force, ensuring suspended loads remain safely clamped in both directions if air pressure drops or an E-stop trips. Operating pressure is capped at 0.7 MPa.
This 125 mm bore, 800 mm stroke unit provides 8590 N of push drive force while utilizing a separate G1/8 release port to unlock the collet mechanism. Because this SKU lacks the -S magnet option, it does not support CMSE or DMSE position sensors. The lock engages only after the piston stops, requiring at least 0.5 s 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 BSE125X800 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 BSE125X800 Is Used
Heavy Press Rams
Secures 800 mm press rams weighing hundreds of kilos. The 8600 N collet lock prevents gravitational drift during air loss, while the 8590 N drive force handles the heavy cycling.
Automated Foundry Ladles
Holds suspended molten metal ladles firmly in place during E-stops. The fail-safe spring-applied lock ensures the 125 mm bore rod will not drop its dangerous load when live air is exhausted.
Pallet Stacker Hoists
Locks vertical stacker platforms at precise 800 mm heights. The collet mechanism holds the load bidirectionally without consuming air, while the G1/8 release port frees it for movement.
Is the Airtac BSE Clamp Standard Cylinder BSE125X800 the Right Cylinder?
Verify your load requires no more than the 8600 N holding force and 8590 N push force at 0.7 MPa. If you need less holding capacity, the 100 mm bore neighbor offers 5500 N hold and 3927 N push at 0.5 MPa; as the largest available bore, 125 mm is the maximum tier. When replacing a unit, match the 800 mm stroke, PT1/2 cylinder port, and mounting style. Note that SE mounting accessories fit this body perfectly except for the FTC variant.
At 800 mm of travel, side-load risks increase significantly. Use external guide rails to prevent rod bending and ensure smooth operation. Always engage the lock only after the rod fully stops, and release it solely when pressures on both piston sides are balanced.
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 BSE125X800 FAQ
The drive force is 6136 N push and 5734 N pull at 0.5 MPa, peaking at 8590 N push (876 kgf) at 0.7 MPa. The separate static holding force of the rod lock is 8600 N, which holds the load with no live air.
The lock is spring-applied, so losing air instantly clamps the collet to the 32 mm rod, holding the load safely. To release it, apply 0.15-0.7 MPa to the G1/8 release port, ensure both piston sides are pressure-balanced, and wait at least 0.5 s before moving.
