Airtac BSE Clamp Standard Cylinder BSE50X150S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X150S 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 BSE50X150S
The AirTAC BSE50X150S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It provides a bidirectional static holding force of 1400 N. If air pressure drops or an E-stop trips, the collet clamp engages automatically to hold the rod precisely where it stopped.
Operating pressure is capped at 0.7 MPa, and unlocking requires 0.15-0.7 MPa supplied to the separate G1/8 release port. This 50 mm bore unit features a Ø20 mm rod, M16x1.5 rod thread, and a -S magnet for CMSE reed or DMSE electronic sensors. The lock is a holding device, not a dynamic brake; engage it only after the rod stops and release it only when piston pressures are balanced.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X150S 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 BSE50X150S Is Used
Vertical Pneumatic Lift
Holds a 100 kg vertical lift mid-stroke. The 1400 N fail-safe collet prevents dropping if air pressure is lost, while the 982 N push at 0.5 MPa handles the drive.
Overhead Tool Clamp
Secures an overhead machining tool. The spring-applied lock maintains the 1400 N grip during air exhaustion, ensuring the tool stays put without live air.
Pallet Stop Gate
Acts as a mid-conveyor pallet stop. The lock holds the 50 mm rod rigid against impacts during E-stops, preventing drift until the G1/8 port releases it.
Is the Airtac BSE Clamp Standard Cylinder BSE50X150S the Right Cylinder?
Verify your suspended load requires less than the 1400 N holding force. If you need less drive power, the 40 mm bore offers 628 N push at 0.5 MPa and 900 N holding force. If your load exceeds this unit's 982 N push at 0.5 MPa, step up to the 63 mm bore, which provides 1559 N push at 0.5 MPa and 2200 N holding force.
Always engage the lock only after the rod fully stops, and allow at least 0.5 s for release before resuming motion. To replace this cylinder, match the 50 mm bore, 150 mm stroke, PT1/4 cylinder port, and -S magnet. Standard SE mounting accessories fit this ISO 15552 body, 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 BSE50X150S FAQ
The drive force is 982 N push and 825 N pull at 0.5 MPa, or 1374 N push at 0.7 MPa (max 140 kgf). The separate static holding force of the rod lock is 1400 N.
The lock is spring-applied and fail-safe. If air is lost, a collet clamps the rod bidirectionally with 1400 N of force, holding it in place. It is not a dynamic brake; engage it only after stopping.
