Airtac BSE Clamp Standard Cylinder BSE125X1000
The AirTAC Airtac BSE Clamp Standard Cylinder BSE125X1000 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, 1000mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE125X1000
The AirTAC BSE125X1000 is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the Ø32 mm piston rod, delivering a bidirectional static holding force of 8600 N. If air pressure drops or an E-stop trips, the lock engages instantly to hold the load safely in place.
The cylinder operates at 0.15-0.7 MPa, generating a 0.7 MPa push force of 8590 N. Unlocking requires a separate G1/8 port supplied with 0.15-0.7 MPa. Because this 1000 mm stroke lacks the -S magnet option, it has no CMSE or DMSE position sensing on this SKU.
Rod Lock — 8600 N Static Holding (Ø125mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE125X1000 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 BSE125X1000 Is Used
Heavy Vertical Lift Hold
Secures 8600 N suspended machinery platforms instantly on air loss, preventing catastrophic drops during E-stop events.
Press Tool Clamp
Locks heavy stamping dies in place with 8600 N force without consuming live air, ensuring tools stay fixed if pressure drops.
Pallet Stop Gate
Halts and holds 8590 N drive force on heavy assembly lines, keeping massive pallets locked during work cycles.
Is the Airtac BSE Clamp Standard Cylinder BSE125X1000 the Right Cylinder?
Verify your load stays under the 8600 N holding force and 8590 N push. If you need less force, the 100 mm bore offers 3927 N push at 0.5 MPa and a 5500 N hold. If you need more, the 125 mm is the largest standard bore. Always engage the lock only after the rod fully stops, and release it only when piston pressures are balanced, allowing at least 0.5 s for full release.
This unit uses a PT1/2 cylinder port and a G1/8 release port. For a 1000 mm stroke, use a guide to prevent excessive side loads and rod bending. SE mounting accessories fit this body perfectly, except FTC. The lock is a holding device, not a dynamic brake; use safety-rated controls for man-rated or overhead loads.
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 BSE125X1000 FAQ
The spring-applied collet engages automatically on air loss, providing an 8600 N bidirectional hold. Drive forces are 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push at 0.7 MPa, with a max drive of 876 kgf.
Apply 0.15-0.7 MPa to the separate G1/8 release port. Ensure pressures on both sides of the piston are balanced before moving, and allow at least 0.5 s for the collet to fully release.
