Airtac BSE Clamp Standard Cylinder BSE100X50S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X50S 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 Ø25mm rod and holds up to 5500 N in either direction — no drift. Ø100mm bore, 50mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE100X50S
The AirTAC BSE100X50S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 5500 N bidirectional static holding force, clamping the piston rod instantly if air pressure drops. The operating pressure ceiling is 0.15-0.7 MPa, and a separate G1/8 release port governs the lock.
This 100 mm bore unit includes a magnet for position sensing and runs at 30-800 mm/s. The lock engages via collet only after the rod stops, providing true fail-safe drift protection rather than a dynamic brake.
Rod Lock — 5500 N Static Holding (Ø100mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X50S 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.

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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa (max) | 5498 N | — |
| Max drive (@0.7 MPa) | 561 kgf | |
Drive force is separate from the 5500 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 BSE100X50S Is Used
Injection Mold Platens
Secures heavy mold halts mid-travel, using the 5500 N holding force to prevent platen descent if shop air exhausts during an E-stop.
Palletizer Lift Carriage
Holds a vertical lift carriage firmly in place against gravity during air loss, safely suspending the 561 kgf drive load.
Heavy Press Tooling
Clamps large press tooling stationary. The collet locks the rod instantly on pressure loss, preventing tool drop before maintenance.
Is the Airtac BSE Clamp Standard Cylinder BSE100X50S the Right Cylinder?
Verify your suspended load requires 5500 N or less of holding force. If you need less, step down to the 80 mm bore (2513 N push @0.5 MPa, 3600 N hold). If you need more, step up to the 125 mm bore (6136 N push @0.5 MPa, 8600 N hold). Engage the lock only after the rod fully stops, and allow >=0.5 s for release after balancing piston pressures. This 50 mm stroke matches the SE replacement bore, PT1/2 port, and -S magnet.
Quick checklist
- ✓ Load to hold ≤ 5500 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 BSE100X50S FAQ
It is spring-applied and air-released. If air is lost or exhausted, a collet clamps the rod, providing a 5500 N bidirectional static holding force to prevent drift. It is not a dynamic brake; engage it only after the rod stops.
The drive forces are separate from the hold. At 0.5 MPa, push is 3927 N and pull is 3681 N. At the 0.7 MPa ceiling, push is 5497 N (max drive 561 kgf). The static holding force is 5500 N.
