Airtac BSE Clamp Standard Cylinder BSE100X50
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X50 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 BSE100X50
The AirTAC BSE100X50 is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the 25mm rod to deliver a 5500 N bidirectional static holding force with zero live air, ensuring suspended loads remain exactly where they stopped during an E-stop or pressure loss. Operating pressure is capped at 0.7 MPa.
This 100mm bore unit provides 3927 N push force at 0.5 MPa and 5497 N at 0.7 MPa. The lock uses a separate G1/8 release port and must only engage after the rod fully stops. Because it shares the SE body, all standard SE mounting accessories fit this cylinder except FTC.
Rod Lock — 5500 N Static Holding (Ø100mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X50 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.

Where the Airtac BSE Clamp Standard Cylinder BSE100X50 Is Used
Automated Press Feeders
Holds a 100mm bore actuator's 5497 N drive force in place vertically during an air loss, utilizing the 5500 N fail-safe collet lock to prevent heavy sheet metal blanks from crashing downward.
CNC Fixture Clamps
Secures heavy cast iron automotive blocks during machining. The spring-applied lock maintains 5500 N of grip if shop air is exhausted, keeping the workpiece fixed without relying on live pressure.
Pallet Stacker Stops
Prevents drift in high-mass palletizing gantries. When an E-stop trips, the collet engages instantly on the stopped rod, holding the load securely in both directions without dynamic braking wear.
Is the Airtac BSE Clamp Standard Cylinder BSE100X50 the Right Cylinder?
Verify your load requires less than the 5500 N holding capacity and 5497 N maximum drive force. If you need less force, the 80mm bore offers 2513 N push at 0.5 MPa and a 3600 N hold; stepping up to 125mm yields 6136 N push at 0.5 MPa and an 8600 N hold. Always balance pressures on both sides of the piston before unlocking, allowing at least 0.5 seconds for full release prior to motion. This BSE100X50 has a 50mm stroke, a PT1/2 cylinder port, no magnet, and uses an M20x1.5 rod thread.
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 BSE100X50 FAQ
The integrated rod lock is spring-applied, so an air loss causes the collet to clamp the rod automatically. It provides a 5500 N bidirectional static hold, keeping the load exactly where it stopped. It is not a dynamic brake, so the rod must be fully stopped before engagement.
The drive force is separate from the 5500 N holding force. At 0.5 MPa, push is 3927 N and pull is 3681 N. At the 0.7 MPa ceiling, push is 5497 N, yielding a maximum drive of 561 kgf.
