Airtac BSE Clamp Standard Cylinder BSE50X1000S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X1000S 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, 1000mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE50X1000S
The AirTAC BSE50X1000S is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a bidirectional fail-safe holding force of 1400 N, ensuring suspended loads remain exactly where they stopped if air pressure is lost or an E-stop is triggered. Operating pressure is capped at 0.7 MPa.
This 50 mm bore, 1000 mm stroke model includes a -S magnet for position sensing via CMSE reed or DMSE electronic switches. Unlocking the collet requires a separate G1/8 release port, which must be balanced and allowed at least 0.5 s before motion resumes. The lock is a static holding device, not a dynamic brake.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X1000S 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 BSE50X1000S Is Used
Vertical Lift Station
Holds a 1400 N vertical lifting load safely in place during an E-stop or sudden air loss, preventing gravity-driven drops in material handling lifts.
Overhead Tooling Clamp
Maintains exact clamping position on an overhead machining head when shop air is exhausted, relying on the mechanical collet rather than live air pressure.
Pallet Stopper Gate
Keeps a heavy pallet stop gate extended and locked against drive forces up to 1374 N at 0.7 MPa, ensuring the gate stays put even if the control system fails.
Is the Airtac BSE Clamp Standard Cylinder BSE50X1000S the Right Cylinder?
Verify your load does not exceed the 1400 N static holding force. If you need less drive force, the 40 mm bore offers 628 N push at 0.5 MPa and 900 N hold; stepping up to the 63 mm bore yields 1559 N push at 0.5 MPa and 2200 N hold. Always engage the lock only after the rod fully stops, and release it solely when piston pressures are balanced.
At 1000 mm stroke, long piston travel increases susceptibility to side loads. Use external guide rails to prevent rod binding and premature seal wear. When replacing, match the 50 mm bore, 1000 mm stroke, PT1/4 port, and mounting accessory (SE-compatible except FTC).
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 BSE50X1000S FAQ
The spring-applied collet immediately engages and clamps the rod, providing a bidirectional static holding force of 1400 N to prevent drift. It is a fail-safe hold, not a dynamic brake.
Drive force at 0.5 MPa is 982 N push and 825 N pull; at 0.7 MPa push is 1374 N, yielding a max drive of 140 kgf. The separate static holding force of the lock is 1400 N.
