Airtac BSE Clamp Standard Cylinder BSE50X150
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X150 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, 150mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE50X150
The AirTAC BSE50X150 is a double-acting, single-rod 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, preventing drift when air is exhausted or an E-stop trips. Operating pressure is capped at 0.7 MPa.
This 50 mm bore unit uses a Ø20 mm rod with an M16x1.5 thread, PT1/4 cylinder ports, and a separate G1/8 release port. The lock clamps via collet mechanism only after the rod stops; you must balance piston pressures and allow at least 0.5 s before moving. This SKU has no 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 BSE50X150 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 BSE50X150 Is Used
Pneumatic Vertical Lift
Secures a 1400 N vertical elevator platform instantly if compressed air drops, preventing uncontrolled descent while the drive provides 982 N push at 0.5 MPa.
Machine Tool Clamp
Holds a machining fixture rigidly in place during an E-stop event, relying on the fail-safe collet lock rather than live air to maintain clamping position.
Pallet Gate Stop
Blocks a conveyor lane segment reliably; the spring-applied lock ensures the stop remains extended even during a plant air failure until the G1/8 port is pressurized.
Is the Airtac BSE Clamp Standard Cylinder BSE50X150 the Right Cylinder?
Verify your suspended load stays below the 1400 N holding force. If you need less drive, 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 both sides are pressure-balanced.
To replace this cylinder, match the 50 mm bore, 150 mm stroke, PT1/4 port, and basic mounting. SE mounting accessories fit perfectly except FTC. Since the 150 mm stroke is under 300 mm, standard side-load concerns are minimal, but always ensure axial alignment to prevent binding.
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 BSE50X150 FAQ
The spring-applied collet engages automatically to provide a 1400 N static holding force in both directions without live air. 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 first balance the air pressure on both sides of the piston. Then supply 0.15-0.7 MPa to the separate G1/8 release port to overcome the spring and unclamp the collet, allowing at least 0.5 seconds for full release before commanding cylinder movement.
