Airtac BSE Clamp Standard Cylinder BSE40X200S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE40X200S 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, 200mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE40X200S
The AirTAC BSE40X200S is a double-acting ISO 15552 profile cylinder featuring a 16mm rod and an integrated spring-applied, air-released rod lock. A collet clamps the rod automatically, delivering a 900N bidirectional static holding force with zero live air. This fail-safe mechanism prevents drift in vertical or suspended loads the moment pressure drops or an E-stop trips. Operating pressure is capped at 0.7 MPa.
Unlocking requires supplying 0.15-0.7 MPa to the separate G1/8 release port. The lock is a holding device, not a dynamic brake; engage it only after the rod fully stops, and allow at least 0.5s for release after balancing piston pressures before resuming motion. This -S variant includes a magnet for CMSE reed and DMSE electronic sensors.
Rod Lock — 900 N Static Holding (Ø40mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE40X200S 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 (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 BSE40X200S Is Used
Palletizer Vertical Lift
Holds a 900N vertical lift arm safely mid-stroke during a compressed air failure, preventing pallet descent.
Drill Head Anti-Drift
Clamps a machining drill head at 200mm extension, ensuring the 16mm rod stays locked if air exhausts unexpectedly.
Pallet Stop Gate
Maintains a conveyor stop gate firmly in position during an E-stop, relying on the 900N spring-applied collet hold.
Is the Airtac BSE Clamp Standard Cylinder BSE40X200S the Right Cylinder?
Select this 40mm bore if your load requires up to 879N of drive force at 0.7 MPa and a 900N static hold. If you need less force, the adjacent 32mm bore provides 563N push and 600N holding force. If your load exceeds this model, step up to the 50mm bore, which yields 1374N push and 1400N holding force. Always verify your load stays safely under the 900N hold limit.
For a drop-in replacement, match the 40mm bore, 200mm stroke, PT1/4 cylinder port, and basic mounting. SE mounting accessories fit this ISO 15552 body perfectly, except FTC. Because the stroke is 200mm, standard guidance is sufficient, but always verify side-load limits on your carriage. Remember to engage the lock only when the rod is completely stopped.
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 BSE40X200S FAQ
It is spring-applied and fail-safe. If air is lost, a collet clamps the 16mm rod, providing a 900N bidirectional static hold. It is not a dynamic brake; engage it only after the rod stops, and allow at least 0.5s for release.
At 0.5 MPa, push is 628N and pull is 528N. At 0.7 MPa, push is 879N, yielding a max drive of 90 kgf. The separate static holding force of the lock is 900N.
