Airtac BSE Clamp Standard Cylinder BSE50X80
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X80 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, 80mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE50X80
The AirTAC BSE50X80 is a double-acting, single-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 1400 N bidirectional static holding force that secures your load in place the moment air pressure is lost or exhausted.
Operating pressure is capped at 0.15-0.7 MPa, and the lock is released via a separate G1/8 port. The lock engages a clamping collet only after the rod has fully stopped, meaning it functions as a static hold rather than a dynamic brake. This specific SKU lacks a magnet, so it does not support position sensing.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X80 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 BSE50X80 Is Used
Vertical Pneumatic Lift
Secures elevated packaging platens during air loss, using the 1400 N holding force to prevent sudden drops while the 982 N push at 0.5 MPa handles the upward drive.
Tooling Clamp Hold
Maintains clamping pressure on machined parts if E-stop is hit, keeping the workpiece fixed without live air while the cylinder provides 825 N pull force during operation.
Pallet Stop Gate
Holds a conveyor stop pin rigidly in place during halts, using the fail-safe collet lock to resist impact rather than relying on the 30 mm adjustable air cushions.
Is the Airtac BSE Clamp Standard Cylinder BSE50X80 the Right Cylinder?
Verify your suspended load requires less than the 1400 N static holding force. If you need less drive and hold, 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 providing 1559 N push at 0.5 MPa and 2200 N hold. Always balance pressures on both sides of the piston before unlocking, allowing at least 0.5 s for full release.
For exact replacement matching, confirm the 50 mm bore, 80 mm stroke, PT1/4 cylinder port, and standard mounting. SE-compatible mounting accessories fit this cylinder except FTC. Since the 80 mm stroke is under 300 mm, standard side-load concerns are minimal, but always ensure axial alignment to prevent binding.
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 BSE50X80 FAQ
The integrated collet is spring-applied and air-released, meaning a loss of air instantly engages the lock. It provides a 1400 N bidirectional static holding force to keep the rod exactly where it stopped, though it is not a dynamic brake and should only be engaged after motion ceases.
The drive forces are 982 N push at 0.5 MPa, 825 N pull at 0.5 MPa, and 1374 N push at 0.7 MPa, equating to a max drive of 140 kgf. This drive force is separate from the 1400 N static holding force generated by the spring collet.
