Airtac BSE Clamp Standard Cylinder BSE100X350
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X350 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, 350mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE100X350
The AirTAC BSE100X350 is a double-acting, single-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a drive force of 5497 N at 0.7 MPa while providing a 5500 N static bidirectional holding force. This fail-safe collet mechanism clamps the 25 mm rod instantly if air is exhausted or an E-stop trips, holding the load securely without consuming live air.
Operating pressure is capped at 0.7 MPa, and the lock unlocks via a separate G1/8 port. Because this SKU lacks a magnet, it does not support position sensing. The 350 mm stroke requires external guide rails to prevent side-load wear on the 36 mm adjustable air cushions. SE mounting accessories fit this body, except FTC.
Rod Lock — 5500 N Static Holding (Ø100mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X350 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa (max) | 5498 N | — |
| Max drive (@0.7 MPa) | 561 kgf | |
Drive force is separate from the 5500 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 BSE100X350 Is Used
Press Tooling Hold
Secures 5000 N press tooling vertically on a 350 mm stroke, preventing a crash drop if the 0.7 MPa air supply fails during an E-stop.
Pallet Stopper Gate
Acts as a fail-safe stop gate on a heavy assembly conveyor, using the 5500 N holding force to resist forward pallet momentum if plant air is lost.
Injection Mold Platen
Locks a mold platen mid-travel during maintenance, holding the 25 mm rod stationary against gravity without relying on the 36 mm air cushion.
Is the Airtac BSE Clamp Standard Cylinder BSE100X350 the Right Cylinder?
Verify your suspended load is under the 5500 N holding force limit. If your load is lighter, the 80 mm bore offers 2513 N push at 0.5 MPa and 3600 N holding force. If you need more stopping power, the 125 mm bore provides 6136 N push at 0.5 MPa and 8600 N holding force. 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. When replacing, match the 100 mm bore, 350 mm stroke, PT1/2 port, and mounting choice.
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 BSE100X350 FAQ
The drive force is 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, with a max drive of 561 kgf. The separate static holding force of the rod lock is 5500 N.
The spring-applied collet clamps the rod instantly, providing a 5500 N bidirectional fail-safe hold. To release, supply 0.15-0.7 MPa to the G1/8 port, balance piston pressures, and wait 0.5 s before moving.
