Airtac BSE Clamp Standard Cylinder BSE50X700
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X700 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, 700mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE50X700
The AirTAC BSE50X700 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 required, ensuring suspended loads remain exactly where they stopped if pressure drops. Operating pressure is capped at 0.7 MPa, and the lock mechanism operates entirely independently from the adjustable air cushions.
This specific SKU lacks a magnet (-S), meaning it cannot support CMSE or DMSE position sensors. Unlocking the collet requires supplying air to the separate G1/8 release port, and you must allow at least 0.5 seconds for full release before initiating movement. The lock engages only after the piston rod comes to a complete stop.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X700 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 BSE50X700 Is Used
Palletizer Lift Arm
Holds a 1400 N vertical lift arm securely in mid-stroke if the main air supply is exhausted, preventing sudden drops during an E-stop event.
Pallet Stop Gate
Maintains a rigid 700 mm barrier to halt heavy pallet traffic, locking instantly on air loss so the gate stays put even under impact.
Clamp Fixture
Secures a workpiece against 982 N of push force at 0.5 MPa, engaging its fail-safe collet to prevent the clamp from loosening if supply pressure drops.
Is the Airtac BSE Clamp Standard Cylinder BSE50X700 the Right Cylinder?
Verify your load requires a holding force of 1400 N or less. If you need less drive force, the adjacent 40 mm bore offers a 628 N push at 0.5 MPa and a 900 N hold; for heavier suspension, the 63 mm bore provides a 1559 N push at 0.5 MPa and a 2200 N hold.
At 700 mm of stroke, lateral side-loads can damage the seals and guide bearing; use an external linear guide to support the load. To replace this unit, match the 50 mm bore, 700 mm stroke, PT1/4 cylinder port, and note that SE mounting accessories fit BSE bodies except FTC.
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 BSE50X700 FAQ
The drive force at 0.5 MPa is 982 N push and 825 N pull; at 0.7 MPa, push is 1374 N (max 140 kgf). The static holding force of the rod lock is 1400 N. Drive force moves the load, while the holding force keeps it stationary with no live air.
The lock is spring-applied, so an air loss instantly clamps the collet onto the rod, providing a 1400 N bidirectional hold. To release it safely, balance pressures on both sides of the piston, supply 0.15-0.7 MPa to the G1/8 release port, and wait at least 0.5 seconds before moving.
