Airtac BSE Clamp Standard Cylinder BSE50X200
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X200 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 Ø20mm rod and holds up to 1400 N in either direction — no drift. Ø50mm bore, 200mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE50X200
The AirTAC BSE50X200 is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the Ø20 mm piston rod, delivering a 1400 N bidirectional static holding force. If air is lost or an E-stop trips, the rod is held securely in both directions at whatever position it stopped. Operating pressure is capped at 0.15-0.7 MPa.
The lock is fail-safe, not a dynamic brake. You must engage it only after the rod stops, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving. Unlocking requires a separate G1/8 release port. This SKU has no -S magnet, so it does not support CMSE or DMSE position sensors. SE mounting accessories fit this body, except FTC.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X200 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa (max) | 1374 N | — |
| Max drive (@0.7 MPa) | 140 kgf | |
Drive force is separate from the 1400 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 BSE50X200 Is Used
Vertical Lift Hold
Secures a 1400 N vertical machining head from dropping when shop air is exhausted, using the collet lock instead of live air pressure.
Pallet Stop Gate
Holds a mid-stroke stop gate rigid during an E-stop on a packaging conveyor, with the 982 N drive force at 0.5 MPa handling the normal push.
Tool Clamp
Maintains a clamped fixture position on an assembly line during pressure loss, preventing the 1374 N drive force from drifting and dropping the part.
Is the Airtac BSE Clamp Standard Cylinder BSE50X200 the Right Cylinder?
Verify your load to hold is at or below the 1400 N figure. If you need less drive or hold, the 40 mm bore offers 628 N push at 0.5 MPa and 900 N holding force. If you need more, the 63 mm bore provides 1559 N push at 0.5 MPa and 2200 N holding force. Match your replacement by bore, stroke, PT1/4 port, and mounting. Since stroke is 200 mm, ensure adequate guide support to prevent side-load wear on the collet.
Quick checklist
- ✓ Load to hold ≤ 1400 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 BSE50X200 FAQ
It provides a 1400 N bidirectional static holding force. The spring-applied collet clamps the rod automatically if air is lost, holding the load in place without live air.
Drive force is 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and max 140 kgf. To release safely, balance pressures on both sides and supply 0.15-0.7 MPa to the G1/8 release port, waiting at least 0.5 s before moving.
