Airtac BSE Clamp Standard Cylinder BSE50X160
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X160 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, 160mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE50X160
The AirTAC BSE50X160 is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a 1400 N bidirectional static holding force with no live air required, ensuring suspended loads remain exactly where they stopped during an E-stop or pressure loss. Operating pressure is capped at 0.15-0.7 MPa.
This 50 mm bore, 160 mm stroke unit uses a separate G1/8 release port to overcome the internal collet clamp. The lock is a holding device, not a dynamic brake; you must engage it only after the rod fully stops and release it only when piston pressures are balanced. It uses standard SE mounting accessories (except FTC) and lacks a magnet on this SKU, meaning no CMSE or DMSE position sensors can be fitted.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X160 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 BSE50X160 Is Used
Packaging Machine Vertical Lift
Holds a 1400 N vertical lifting carriage securely in place during an unexpected air loss event, preventing product crashes on a packaging line.
CNC Tooling Clamp
Maintains 982 N of push force @0.5 MPa to position tooling, while the fail-safe collet lock stops the tool from dropping onto the workpiece if the main air supply is exhausted.
Palletizing Safety Gate
Keeps a heavy safety gate locked mid-stroke during machine E-stop activation, using the spring-applied collet to resist bidirectional drift without continuous air.
Is the Airtac BSE Clamp Standard Cylinder BSE50X160 the Right Cylinder?
Verify your suspended load stays under the 1400 N static holding force. If you need less holding capacity, step down to the 40 mm bore (628 N push @0.5 MPa, 900 N hold); if your load exceeds 1400 N, step up to the 63 mm bore (1559 N push @0.5 MPa, 2200 N hold). The 160 mm stroke is under 300 mm, so standard side-load risks are minimal, but always ensure linear guide alignment. For safe operation, engage the lock only after the rod stops, balance pressures, and allow at least 0.5 s before moving. Replacement requires matching the 50 mm bore, 160 mm stroke, PT1/4 cylinder port, and specific mounting.
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 BSE50X160 FAQ
The integrated spring-applied collet immediately clamps the piston rod, providing a 1400 N bidirectional static holding force with no live air. This prevents the load from drifting, though you should use safety-rated controls for man-rated or overhead lifting applications.
The drive force is 982 N push and 825 N pull @0.5 MPa, 1374 N push @0.7 MPa, with a maximum drive of 140 kgf. The separate static holding force of the rod lock is 1400 N, which is completely independent of the drive force.
