Airtac BSE Clamp Standard Cylinder BSE40X500S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X500S 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 Ø16mm rod and holds up to 900 N in either direction — no drift. Ø40mm bore, 500mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE40X500S
The AirTAC BSE40X500S is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a 900 N bidirectional static holding force to prevent drift, even with zero live air. Operating pressure is capped at 0.7 MPa.
The lock uses a clamping collet mechanism, requiring a separate G1/8 release port to unlock. Because the lock is fail-safe, exhausting air or hitting an E-stop instantly clamps the rod. The air cushion is only for end-of-stroke deceleration; the collet provides the true holding force.
Rod Lock — 900 N Static Holding (Ø40mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE40X500S 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa (max) | 880 N | — |
| Max drive (@0.7 MPa) | 90 kgf | |
Drive force is separate from the 900 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 BSE40X500S Is Used
Vertical Pneumatic Lift
Holds a 900 N vertical load in place instantly if air pressure drops, preventing a raised platform from crashing down during an E-stop event.
Tooling Clamp Station
Secures a machined part under 628 N of push force @0.5 MPa, then locks the 500 mm stroke to maintain the exact clamp position without consuming continuous live air.
Pallet Stopper Gate
Acts as a fail-safe stop for incoming pallets, absorbing the impact via adjustable cushions and locking the 40 mm rod to hold the load securely during line halts.
Is the Airtac BSE Clamp Standard Cylinder BSE40X500S the Right Cylinder?
Verify your suspended load stays under the 900 N static holding force. If you need less holding capacity, step down to the 32 mm bore (402 N push @0.5 MPa, 600 N hold). For heavier loads, step up to the 50 mm bore (982 N push @0.5 MPa, 1400 N hold). Always engage the lock only after the rod fully stops, and allow >=0.5 s for release after balancing piston pressures.
This 500 mm stroke configuration requires external guide rails to prevent side-load damage. To match this replacement exactly, confirm the 40 mm bore, 500 mm stroke, PT1/4 cylinder port, and the -S magnet for CMSE or DMSE sensors. SE mounting accessories fit, except FTC.
Quick checklist
- ✓ Load to hold ≤ 900 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 BSE40X500S FAQ
The spring-applied collet instantly engages, providing a 900 N bidirectional static hold to prevent rod drift. It is a fail-safe lock, not a dynamic brake, so it only engages after the rod has stopped moving.
Drive force is 628 N push and 528 N pull @0.5 MPa, 879 N push @0.7 MPa (max 90 kgf). The separate static holding force from the rod lock is 900 N.
