Airtac BSE Clamp Standard Cylinder BSE125X100S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE125X100S 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, 100mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE125X100S
The AirTAC BSE125X100S 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 zero live air, providing true fail-safe drift protection for heavy suspended loads. Operating pressure is capped at 0.15-0.7 MPa, and the standard -S magnet supports CMSE reed and DMSE electronic sensors.
The lock uses a clamping collet mechanism engaged by spring force and released via a separate G1/8 port. This lock is a static holding device, not a dynamic brake; it must only engage after the rod stops, requiring >=0.5 s for full release. The cylinder runs at 30-500 mm/s with a 40 mm adjustable air cushion at both ends, while the lock itself provides the true holding power.
Rod Lock — 8600 N Static Holding (Ø125mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE125X100S 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 BSE125X100S Is Used
Heavy Press Tooling Hold
Secures 8600 N press dies mid-stroke. The spring collet engages instantly on air loss, preventing heavy tooling from dropping during an E-stop.
Pallet Stop Gate
Halts 8590 N of pallet drive force. The fail-safe lock keeps the gate raised securely even if the plant air supply is exhausted completely.
Vertical Lift Arm
Holds raised manipulator arms carrying maximum 876 kgf drive loads. The bidirectional collet locks the 32 mm rod firmly in both directions.
Is the Airtac BSE Clamp Standard Cylinder BSE125X100S the Right Cylinder?
Verify your suspended load stays below the 8600 N static holding limit. If your drive requirement is lower, stepping down to the 100 mm bore yields 3927 N push at 0.5 MPa and 5500 N holding force. If you need more drive, this 125 mm bore is the largest available, providing 6136 N push at 0.5 MPa and 8590 N at 0.7 MPa. Always balance pressures on both sides of the piston before unlocking, and allow >=0.5 s for release. For replacement matching, confirm the 125 mm bore, 100 mm stroke, PT1/2 cylinder port, and -S magnet. SE mounting accessories fit this ISO 15552 body perfectly, except FTC.
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 BSE125X100S FAQ
The lock is spring-applied and air-released. If air is lost or an E-stop trips, the clamping collet engages the 32 mm rod instantly, providing an 8600 N bidirectional static hold. It is a static lock, not a dynamic brake, so engage it only after the rod stops.
The drive force at 0.5 MPa is 6136 N push and 5734 N pull. At the 0.7 MPa ceiling, push is 8590 N (max 876 kgf). The separate static holding force of the rod lock is 8600 N. Always balance piston pressures before unlocking.
