Airtac BSE Clamp Standard Cylinder BSE125X175S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE125X175S 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, 175mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE125X175S
The AirTAC BSE125X175S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a robust 8600 N bidirectional static holding force with zero live air, ensuring heavy suspended loads stay fixed during pressure loss or E-stops. Operating pressure is capped at 0.15-0.7 MPa.
This 125mm bore features a PT1/2 cylinder port and a separate G1/8 release port. The lock uses a clamping collet mechanism, not the adjustable air cushion, to secure the 32mm rod. Because it carries the -S option, it supports CMSE reed and DMSE electronic sensors for position feedback.
Rod Lock — 8600 N Static Holding (Ø125mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE125X175S 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.

| Stroke | 175 mm |
| Static holding force | 8600 N |
| Cylinder port | PT1/2 |
| Lock-release port | G1/8 |
| Rod thread | M27×2 |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Unlocking pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Adjustable, 40 mm |
| Max stroke | Up to 1000 mm |
Specifications follow the official AirTAC BSE datasheet. The lock uses the SE standard body; SE mounting accessories fit BSE except FTC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
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 BSE125X175S Is Used
Heavy Vertical Lift Hold
Secures a 850kg vertical press platen mid-stroke, providing 8600 N of fail-safe holding force if plant air drops suddenly.
Overhead Tool Clamp
Locks a large machining fixture in place with no live air, guaranteeing heavy tooling does not drift or drop during an emergency stop.
Pallet Stop Gate
Holds a loaded pallet conveyor gate rigid in both directions, using the spring-applied collet to maintain position through heavy shock loads.
Is the Airtac BSE Clamp Standard Cylinder BSE125X175S the Right Cylinder?
Verify your load stays under the 8600 N holding force. If you need less force, the BSE100 bore offers 3927 N push at 0.5 MPa and a 5500 N hold. As the largest standard size, stepping up requires a custom solution. Remember to engage the lock only after the rod fully stops and release it only when piston pressures are balanced, allowing at least 0.5 s before moving.
For exact replacement, match the 175mm stroke, PT1/2 port, and your specific mounting code. SE mounting accessories fit this body perfectly, except FTC which is unavailable for BSE. Even at 175mm stroke, verify guide support to prevent excessive side-load on the collet.
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 BSE125X175S FAQ
The lock is spring-applied and air-released, meaning a loss of air instantly engages the clamping collet. It provides an 8600 N bidirectional static hold with no live air, but it is not a dynamic brake; the rod must be stopped before engagement.
The drive force is 6136 N push and 5734 N pull at 0.5 MPa, or 8590 N push at 0.7 MPa (876 kgf max drive). This is separate from the 8600 N static holding force generated by the rod lock.
