Airtac BSE Clamp Standard Cylinder BSE50X1000
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X1000 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 BSE50X1000
The AirTAC BSE50X1000 is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 1400 N bidirectional static holding force with no live air, keeping suspended loads exactly where they stopped during an E-stop or pressure loss. Drive pressure is capped at 0.15-0.7 MPa, and the lock uses a dedicated G1/8 release port.
This 50 mm bore unit exerts 1374 N of push force at 0.7 MPa while running at 30-800 mm/s. Because the clamping collet is spring-applied, the unit is fail-safe. The lock is a holding device, not a dynamic brake; engage it only after the rod fully stops and release it only when piston pressures are balanced, allowing at least 0.5 seconds before moving. This SKU lacks a magnet, so position sensing is not available.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X1000 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.

| 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 BSE50X1000 Is Used
Palletizer Vertical Lift
Holds a 1400 N lifted pallet carriage securely in place during air loss, preventing drift while the 982 N push drive positions goods at 0.5 MPa.
CNC Tool Change Arm
Maintains a heavy tool carousel position with fail-safe collet clamping, ensuring the 1374 N drive stroke does not drop unexpectedly under E-stop.
Pallet Stop Gate
Locks a 1000 mm stroke stop gate rigid across a conveyor line with 1400 N of static hold, absorbing impact without drifting when air is exhausted.
Is the Airtac BSE Clamp Standard Cylinder BSE50X1000 the Right Cylinder?
Verify your load requires 1400 N or less of holding force. If you need less drive and hold, the 40 mm bore offers 628 N push at 0.5 MPa and 900 N of hold. If you need more, step up to the 63 mm bore for 1559 N push at 0.5 MPa and 2200 N of hold. Always engage the lock only after the rod stops, and release it only when pressures are balanced, waiting 0.5 seconds before moving.
For a direct replacement, match the 50 mm bore, 1000 mm stroke, PT1/4 cylinder port, and your specific mounting code. SE mounting accessories fit this ISO 15552 body perfectly except for FTC. Because this stroke is 1000 mm, use a guide rail to prevent excessive side-load deflection on the piston rod.
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 BSE50X1000 FAQ
The drive force at 0.5 MPa is 982 N push and 825 N pull; at 0.7 MPa push is 1374 N, equating to 140 kgf max drive. The integrated rod lock provides a separate 1400 N bidirectional static holding force with no live air.
The lock is spring-applied and fail-safe. If air is lost or exhausted, a clamping collet engages the 20 mm rod immediately, providing 1400 N of bidirectional hold. You must balance piston pressures and wait 0.5 seconds before releasing it via the G1/8 port.
