Airtac BSE Clamp Standard Cylinder BSE125X200
The AirTAC Airtac BSE Clamp Standard Cylinder BSE125X200 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, 200mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE125X200
The AirTAC BSE125X200 is a double-acting single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the Ø32 mm piston rod automatically, delivering an 8600 N bidirectional static holding force with zero live air required to maintain position. Operating pressure is capped at 0.7 MPa.
This fail-safe mechanism ensures that suspended or vertical loads remain exactly where they stopped if air pressure drops, is exhausted, or an emergency stop is triggered. The lock is a static holding device, not a dynamic brake. You must engage it only after the rod fully stops, and release it only when piston pressures are balanced, allowing at least 0.5 s for full release before motion.
Rod Lock — 8600 N Static Holding (Ø125mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE125X200 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 (Ø125mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 6136 N | 5734 N |
| 0.7 MPa (max) | 8590 N | — |
| Max drive (@0.7 MPa) | 876 kgf | |
Drive force is separate from the 8600 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 BSE125X200 Is Used
Heavy Press Tooling Clamp
Holds 8600 N against heavy press tooling. The spring-applied collet prevents the 8590 N drive load from dropping if shop air fails during forming.
Pallet Lifter Vertical Hold
Secures raised pallets in automated storage systems. The fail-safe lock engages instantly on E-stop, preventing uncommanded descent until air is restored.
Oversized Parts Stopper
Acts as a rigid stop for large workpieces on heavy conveyors. The 8600 N bidirectional hold ensures the rod stays locked against heavy side impacts.
Is the Airtac BSE Clamp Standard Cylinder BSE125X200 the Right Cylinder?
Verify your load stays below the 8600 N holding force and 8590 N push force at 0.7 MPa. If you need less force, the adjacent Ø100 bore yields 3927 N push at 0.5 MPa with a 5500 N hold. For heavier demands, this Ø125 is the largest standard size, offering 6136 N push at 0.5 MPa and an 876 kgf max drive. Always balance pressures before unlocking.
When replacing a unit, match the 200 mm stroke, PT1/2 port, and specific mounting code. SE mounting accessories fit this body perfectly except FTC. Since this SKU lacks a magnet (-S), it supports no position sensors. For this 200 mm stroke, standard guide rails should adequately manage side loads without requiring external load-bearing guides.
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 BSE125X200 FAQ
The spring-applied collet clamps the rod immediately, providing an 8600 N bidirectional static hold with no live air. It keeps the load exactly where it stopped, but it is not a dynamic brake for moving loads.
Drive force is 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push at 0.7 MPa, equating to 876 kgf max drive. The static holding force from the lock is 8600 N.
