Airtac BSE Clamp Standard Cylinder BSE50X225
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X225 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, 225mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE50X225
The AirTAC BSE50X225 is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the Ø20 mm piston rod, delivering a 1400 N bidirectional static holding force with zero live air required. This fail-safe mechanism ensures suspended loads remain exactly where they stopped if air pressure drops or an E-stop is triggered.
Operating pressure is capped at 0.7 MPa, and unlocking requires 0.15-0.7 MPa supplied to the dedicated G1/8 release port. The lock is a holding device, not a dynamic brake; it must only engage after the rod stops. This 50 mm bore model features a PT1/4 cylinder port, 30 mm adjustable air cushions at both ends, and operates at speeds of 30-800 mm/s.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X225 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 BSE50X225 Is Used
Vertical Lift Platforms
Holds a suspended vertical lift stage securely with 1400 N of fail-safe force, preventing a sudden drop if the main air supply is exhausted mid-cycle.
Pneumatic Machining Clamps
Locks a tooling clamp in position on an CNC machining cell. The collet engages only after the 982 N drive force stops, preventing drift during cutting.
Pallet Stop Gates
Maintains a raised pallet stop gate on a packaging conveyor during an emergency stop, securely holding the load without relying on continuous air pressure.
Is the Airtac BSE Clamp Standard Cylinder BSE50X225 the Right Cylinder?
Verify your load requires a holding force of 1400 N or less. If you need less drive and hold, the 40 mm bore neighbor offers 628 N push at 0.5 MPa and 900 N holding force. If your load exceeds this unit, stepping up to the 63 mm bore provides 1559 N push at 0.5 MPa and 2200 N holding force. Always balance pressures on both sides of the piston before releasing the lock, allowing at least 0.5 s for full release before commanding motion.
When replacing a unit, match the 50 mm bore, 225 mm stroke, PT1/4 port, and mounting style. SE mounting accessories fit this ISO 15552 body perfectly, except for FTC. This specific SKU lacks a magnet (-S), meaning it cannot support CMSE or DMSE position sensors. For the 225 mm stroke, ensure external guides support any side loads to prevent uneven wear on the collet lock.
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 BSE50X225 FAQ
The drive force at 0.5 MPa is 982 N push and 825 N pull, with a maximum push of 1374 N at 0.7 MPa (140 kgf). The separate spring-applied rod lock provides a 1400 N static holding force. Never confuse the two; the lock only holds a stationary load.
The lock is spring-applied, so if air is lost, the collet immediately clamps the rod with 1400 N of bidirectional force. To release it safely, balance the piston pressures, supply 0.15-0.7 MPa to the G1/8 release port, and wait at least 0.5 s before moving the cylinder.
