Airtac BSE Clamp Standard Cylinder BSE50X200S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X200S 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 Ø20mm rod and holds up to 1400 N in either direction — no drift. Ø50mm bore, 200mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE50X200S
The AirTAC BSE50X200S is a double-acting, single-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It provides a 1400 N bidirectional static holding force with no live air required, ensuring suspended loads remain safely fixed if pressure drops or an E-stop is hit. Operating pressure is capped at 0.7 MPa.
A separate G1/8 release port supplies 0.15-0.7 MPa to unlock the clamping collet. The lock is not a dynamic brake; engage it only after the rod stops and release it only when piston pressures are balanced, allowing at least 0.5 seconds before moving. The -S magnet enables position sensing with CMSE reed or DMSE electronic sensors.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X200S 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa (max) | 1374 N | — |
| Max drive (@0.7 MPa) | 140 kgf | |
Drive force is separate from the 1400 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 BSE50X200S Is Used
Vertical Lift Hold
Secures a 1400 N vertical machining axis instantly on air loss, preventing a suspended spindle or gantry from drifting downward when shop pressure fails.
Tool Clamp Retention
Maintains a clamped fixture position with 1400 N static force during an E-stop, ensuring the workpiece tooling does not drop or release unexpectedly.
Pallet Stop Gate
Holds a pneumatic lane stop firmly in place against accumulating carton traffic, locking bidirectionally with zero live air to prevent creep during pauses.
Is the Airtac BSE Clamp Standard Cylinder BSE50X200S the Right Cylinder?
Verify your load requires a holding force of 1400 N or less. If you need less drive, the 40 mm bore offers 628 N push at 0.5 MPa and 900 N holding force. If you need more, the 63 mm bore provides 1559 N push at 0.5 MPa and 2200 N holding force. Always engage the lock only after the rod stops, and release it only when pressures are balanced, waiting at least 0.5 seconds before motion.
To replace this unit, match the 50 mm bore, 200 mm stroke, PT1/4 cylinder port, and -S magnet. The ISO 15552 mounting interface means SE accessories fit perfectly, except FTC. The lock-release port is always G1/8. For this 200 mm stroke, ensure proper guide alignment to prevent side-load wear on the seals.
Quick checklist
- ✓ Load to hold ≤ 1400 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 BSE50X200S FAQ
The spring-applied collet clamps the rod immediately, providing a 1400 N bidirectional static hold with no live air. It is a fail-safe lock, not a dynamic brake, so it only engages after the rod has stopped.
The drive force is 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, equating to 140 kgf max drive. This is separate from the 1400 N static holding force of the spring-applied rod lock.
