Airtac BSE Clamp Standard Cylinder BSE50X160S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X160S 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 BSE50X160S
The AirTAC BSE50X160S 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 with no live air, providing true fail-safe drift protection for suspended loads. Operating pressure is capped at 0.7 MPa, and the cylinder port is PT1/4.
This 50 mm bore, 160 mm stroke variant includes a magnet for position sensing. The lock uses a separate G1/8 release port and clamps the piston rod via a collet mechanism. Because it is built on the standard SE body, all SE mounting accessories fit except FTC.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X160S 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 BSE50X160S Is Used
Vertical Pneumatic Lifts
Secures a 140 kg vertical lift stage instantly on air loss, preventing gravity drift while handling 982 N push force at 0.5 MPa.
Overhead Tooling Clamps
Holds a machining fixture rigidly in place during an E-stop, using the 1400 N collet grip to keep the 825 N pull load from slipping.
Pallet Diverter Gates
Locks a routing gate in the extended position on a packaging line, ensuring the load stays put even if the main air supply is exhausted.
Is the Airtac BSE Clamp Standard Cylinder BSE50X160S the Right Cylinder?
Verify your load requires 1400 N or less of holding force. If you need less, step down to the 40 mm bore (628 N push @0.5 MPa, 900 N hold). If you need more, step up to the 63 mm bore (1559 N push @0.5 MPa, 2200 N hold). Always engage the lock only after the rod fully stops, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving.
To replace this unit, match the 50 mm bore, 160 mm stroke, PT1/4 port, and -S magnet option. The 160 mm stroke is short enough that side-load risks are minimal, but ensure standard alignment to prevent binding. The -S magnet supports CMSE reed and DMSE electronic sensors.
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 BSE50X160S FAQ
If air is lost, a spring applies a collet that clamps the rod bidirectionally, providing a 1400 N static holding force. The drive forces are separate: push is 982 N and pull is 825 N at 0.5 MPa, push is 1374 N at 0.7 MPa, with a max drive of 140 kgf.
The lock is spring-applied and air-released via a separate G1/8 port. You must balance the air pressure on both sides of the piston before releasing the lock, and allow at least 0.5 seconds for full release before commanding cylinder movement.
