The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X225S 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 2200 N in either direction — no drift. Ø63mm bore, 225mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.
The AirTAC BSE63X225S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a bidirectional fail-safe holding force of 2200 N, clamping the Ø20 mm rod instantly if air is exhausted or an E-stop trips. Operating pressure is capped at 0.7 MPa.
Because the lock uses a collet mechanism, it is not a dynamic brake; engage it only after the piston stops and release it only when pressures are balanced, allowing at least 0.5 s before moving. The -S magnet supports CMSE reed and DMSE electronic sensors for position feedback.
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X225S 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.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa (max) | 2182 N | — |
| Max drive (@0.7 MPa) | 223 kgf | |
Drive force is separate from the 2200 N static holding force of the lock. BSE operates up to 0.7 MPa. Size with a safety margin.

Thread: PT (blank) / G. Mounting (BSE): Basic, LB, FA, FB, CA, CB, CR, TC (FTC is not available on BSE). Related: SE (no lock), BSED (double-rod rod lock). Sensors CMSE/DMSE fit magnetic BSE.
Holds a 1500 N lifted pallet assembly securely mid-stroke with zero live air, preventing sudden drops if the main air supply drops out.
Maintains a rigid 1559 N clamping force at 0.5 MPa during machining, locking the 2200 N collet to resist vibration when air is exhausted.
Acts as a fail-safe stop gate on a packaging conveyor, staying firmly extended during E-stops to block 2 m/s product flow instantly.
Verify your suspended load stays under the 2200 N static holding force. If you need less drive, the 50 mm bore offers 982 N push at 0.5 MPa and 1400 N hold; for heavier lifting, the 80 mm bore provides 2513 N push at 0.5 MPa and 3600 N hold. Always engage the lock only after the rod fully stops.
To replace this unit, match the 63 mm bore, 225 mm stroke, PT3/8 cylinder port, and the -S magnet option. SE mounting accessories fit this body perfectly except for FTC. With a 225 mm stroke, use a guide rail to prevent side-load wear on the seals.
Quick checklist
The drive force is 1559 N push and 1402 N pull at 0.5 MPa, or 2182 N push at 0.7 MPa (max 222 kgf). The separate spring-applied rod lock provides a 2200 N bidirectional static holding force with no live air.
Apply 0.15-0.7 MPa to the separate G1/8 release port only after balancing pressures on both sides of the piston. Wait at least 0.5 seconds for the collet to fully retract before commanding cylinder movement.
