Airtac BSE Clamp Standard Cylinder BSE50X800
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X800 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, 800mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE50X800
The AirTAC BSE50X800 is a double-acting ISO 15552 profile cylinder integrating a spring-applied, air-released rod lock. It delivers a 1400 N bidirectional static holding force, clamping the Ø20 mm rod instantly if air pressure drops or an E-stop trips. Operating pressure is capped at 0.7 MPa, and the lock mechanism uses a dedicated G1/8 release port.
This 50 mm bore, 800 mm stroke unit provides 1374 N of push drive force at 0.7 MPa while relying on the collet lock for true fail-safe positioning. It uses an extruded aluminum barrel with no external tie rods. This specific SKU lacks a magnet, so it does not support CMSE or DMSE position sensors.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X800 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 BSE50X800 Is Used
Z-Axis Elevator Hold
Secures a 100 kg vertical lifting platform on a packaging machine. The 1400 N fail-safe collet locks instantly on air loss, while the 982 N push drive at 0.5 MPa handles the standard lift cycle.
Overhead Tool Clamp
Maintains a machining head position during an emergency stop. The spring-applied lock holds the 800 mm stroke rigidly in both directions without needing live air.
Pallet Diverter Gate
Keeps an assembly line routing gate fixed in place across the 800 mm span. The collet engages only after the gate stops, preventing uncontrolled drift during E-stop.
Is the Airtac BSE Clamp Standard Cylinder BSE50X800 the Right Cylinder?
Verify your suspended load requires no more than the 1400 N static holding force. If you need less holding and drive, the 40 mm bore neighbor offers 628 N push at 0.5 MPa and 900 N hold. If your load exceeds this unit, step up to the 63 mm bore, which provides 1559 N push at 0.5 MPa and 2200 N hold. Always engage the lock only after the rod fully stops, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving.
At 800 mm of travel, side-load risks are high; use external guide rails to prevent binding. When replacing, match the 50 mm bore, 800 mm stroke, PT1/4 cylinder port, and mounting choice. SE mounting accessories fit perfectly except for FTC. Because this SKU has no -S magnet, you cannot add reed sensors.
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 BSE50X800 FAQ
The lock is spring-applied and air-released, providing a 1400 N static holding force in both directions if air is lost. The drive force is separate: push is 982 N and pull is 825 N at 0.5 MPa, push is 1374 N at 0.7 MPa, with a max drive of 140 kgf.
You must supply 0.15-0.7 MPa to the separate G1/8 release port. Release the lock only after balancing pressures on both sides of the piston, and wait at least 0.5 s before commanding movement to ensure full disengagement.
