Airtac BSE Clamp Standard Cylinder BSE100X400S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X400S 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, 400mm stroke, PT1/2 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE100X400S
The AirTAC BSE100X400S is a double-acting, single-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 5500 N bidirectional static holding force, ensuring suspended loads stay exactly where they stopped if air pressure drops. Operating pressure is capped at 0.7 MPa, and the cylinder runs at speeds from 30-800 mm/s.
This 100 mm bore, 400 mm stroke model features a PT1/2 cylinder port and a separate G1/8 lock-release port. The included -S magnet enables precise position sensing with CMSE reed or DMSE electronic switches. Remember to engage the collet lock only after the piston stops, and allow at least 0.5 s for full release before resuming motion.
Rod Lock — 5500 N Static Holding (Ø100mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X400S 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 BSE100X400S Is Used
Heavy Press Tooling Clamp
Secures large stamping dies in place. The 5500 N fail-safe hold prevents the tool from slipping downward during an E-stop, while the 5497 N drive force handles the heavy clamping motion.
Pallet Lift and Stop
Halts and elevates loaded pallets on a packaging line. The spring-applied collet locks the 400 mm stroke instantly on air loss, holding the weight securely without drifting downward.
Vertical Material Gate
Actuates a heavy security gate on an automated storage system. If air exhausts unexpectedly, the lock engages to keep the 100 mm bore rod frozen in position, protecting workers below.
Is the Airtac BSE Clamp Standard Cylinder BSE100X400S the Right Cylinder?
Verify your load requires a holding force under 5500 N and a drive force up to 5497 N at 0.7 MPa. If you need less force, the 80 mm bore provides 2513 N push at 0.5 MPa and a 3600 N hold. If you need more, the 125 mm bore offers 6136 N push at 0.5 MPa and an 8600 N hold. Always balance pressures on both sides of the piston before releasing the lock.
For this 400 mm stroke, use a guide rail to prevent excessive side-loading on the rod. When replacing a unit, match the 100 mm bore, 400 mm stroke, PT1/2 port, and mounting style. SE mounting accessories fit this body perfectly except FTC.
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 BSE100X400S FAQ
The integrated rod lock is spring-applied and air-released, making it fail-safe. If air is lost or exhausted, a collet clamps the rod and provides a 5500 N bidirectional static holding force, holding the load in place without live air.
The drive force at 0.5 MPa is 3927 N push and 3681 N pull. At 0.7 MPa, push is 5497 N with a max drive of 561 kgf. The separate static holding force from the rod lock is 5500 N. Never confuse the drive force with the holding force.
