Airtac BSE Clamp Standard Cylinder BSE100X350S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE100X350S 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 BSE100X350S
The AirTAC BSE100X350S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 5500 N bidirectional static holding force with no live air, ensuring suspended loads remain exactly where they stopped if air pressure drops.
Operating pressure is capped at 0.7 MPa. The cylinder runs at 30-800 mm/s, while a separate G1/8 release port unlocks the collet mechanism. The -S magnet supports CMSE reed and DMSE electronic sensors for precise position feedback.
Rod Lock — 5500 N Static Holding (Ø100mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE100X350S 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.

Specifications follow the official AirTAC BSE datasheet. The lock uses the SE standard body; SE mounting accessories fit BSE except FTC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
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 BSE100X350S Is Used
Heavy Vertical Lift
Holds a 500 kg machining head mid-stroke. The 5500 N lock prevents crashing down during an E-stop, while 5497 N push drive handles the lift.
Pallet Stop Gate
Acts as a heavy conveyor stop. The fail-safe collet holds the impact load securely with no live air, keeping the line safe during maintenance.
Press Tool Clamp
Clamps large stamping dies. The spring-applied lock maintains 5500 N grip if air exhausts, and the 3691 N pull retracts the tool safely.
Is the Airtac BSE Clamp Standard Cylinder BSE100X350S the Right Cylinder?
Verify your load stays under the 5500 N holding force. If you need less drive, the 80 mm bore offers 2513 N push at 0.5 MPa and 3600 N hold; if you need more, the 125 mm bore provides 6136 N push at 0.5 MPa and 8600 N hold. At 350 mm stroke, add external guide rails to prevent side-load wear on the rod seals.
Engage the lock only after the rod fully stops. To release safely, balance pressure on both sides of the piston and allow at least 0.5 s before resuming motion. This 100 mm bore uses a PT1/2 cylinder port, a 25 mm rod, and M20x1.5 threads. SE mounting accessories fit 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 BSE100X350S FAQ
The spring-applied collet fails safe, delivering 5500 N of static holding force in both directions with no live air. Drive forces are separate: 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a max drive of 561 kgf.
The lock is not a dynamic brake. Engage it only after the rod stops. To release, balance pressures on both piston sides, apply 0.15-0.7 MPa to the G1/8 release port, and wait at least 0.5 s before moving.
