Airtac BSE Clamp Standard Cylinder BSE50X100
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X100 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, 100mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE50X100
The AirTAC BSE50X100 is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It supplies 982 N push and 825 N pull drive force at 0.5 MPa, while a separate collet mechanism delivers a 1400 N bidirectional static hold with zero live air. Operating pressure is capped at 0.7 MPa.
This fail-safe lock engages automatically if air is exhausted or an E-stop trips, holding the load firmly at its stopped position. Because this SKU lacks the -S magnet option, it does not support CMSE or DMSE position sensors. The cylinder uses a PT1/4 port and a dedicated G1/8 release port to unlock the rod.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X100 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 BSE50X100 Is Used
Vertical Pneumatic Lift
Holds a 140 kg elevated platform in place during an E-stop. The 1400 N fail-safe collet prevents gravity from pulling the load down when shop air drops.
Tooling Clamp
Secures a machining fixture with 982 N of clamping force. If air pressure is lost mid-cycle, the rod lock maintains the 1400 N hold to prevent workpiece movement.
Pallet Stop Gate
Acts as a stop for items on a conveyor. The spring-applied lock keeps the gate extended during an air failure, preventing unexpected pallet movement.
Is the Airtac BSE Clamp Standard Cylinder BSE50X100 the Right Cylinder?
Verify your suspended load requires less than the 1400 N static holding force. If you need less drive, the 40 mm bore offers 628 N push at 0.5 MPa and 900 N hold. If you need more, step up to the 63 mm bore for 1559 N push and 2200 N hold. Always balance pressures on both sides of the piston before releasing the lock, allowing at least 0.5 seconds before commanding motion.
To match this exact replacement, specify the 50 mm bore, 100 mm stroke, PT1/4 thread, and your required ISO 15552 mounting accessory (SE-compatible except FTC). The 100 mm stroke is short enough that side-load guides are less critical, but always ensure the rod is fully stopped before engaging the collet lock.
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 BSE50X100 FAQ
The lock is spring-applied and air-released. If air pressure drops below 0.15 MPa or is exhausted, a collet clamps the 20 mm rod, providing a 1400 N bidirectional static hold. It is not a dynamic brake; the rod must be fully stopped before engagement.
At 0.5 MPa, the drive force is 982 N push and 825 N pull. At the 0.7 MPa maximum operating pressure, push is 1374 N (140 kgf max drive). The separate static holding force of the rod lock is 1400 N.
