Airtac BSE Clamp Standard Cylinder BSE63X125S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X125S 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, 125mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X125S
The AirTAC BSE63X125S 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 2200 N bidirectional static holding force with zero live air. Operating pressure is capped at 0.15-0.7 MPa, and a separate G1/8 release port manages the unlock function.
This fail-safe mechanism prevents drift on suspended loads during E-stops or pressure drops. The lock is a static hold, not a dynamic brake; it must engage only after the rod fully stops, with at least 0.5 s allowed for release. The -S magnet supports CMSE reed and DMSE electronic sensors.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X125S 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.

Theoretical Output Force (Ø63mm)
| 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.

Where the Airtac BSE Clamp Standard Cylinder BSE63X125S Is Used
Vertical Lift Gate
Holds a 1500 N vertical lift gate in place. The 2200 N collet lock prevents gravity drift if air pressure drops, while the 1559 N drive at 0.5 MPa lifts the gate smoothly.
Pneumatic Press Tool
Secures a 1000 N press tooling head. The fail-safe lock clamps the rod instantly on E-stop, ensuring the head does not slip and damage the workpiece.
Pallet Diverter Stop
Blocks heavy pallets on a packaging line. The 222 kgf max drive force extends the stop firmly, and the 2200 N hold resists impact if the conveyor halts abruptly.
Is the Airtac BSE Clamp Standard Cylinder BSE63X125S the Right Cylinder?
Verify your load stays under the 2200 N holding force. If your load is lighter, the 50 mm bore offers 982 N push at 0.5 MPa and 1400 N hold. If you need more drive force, the 80 mm bore provides 2513 N push at 0.5 MPa and 3600 N hold. Both neighbors share SE-compatible mounting accessories.
For exact replacement, match the 63 mm bore, 125 mm stroke, PT3/8 port, and -S magnet. Engage the lock only when the rod is stopped, and release it only when piston pressures are balanced. The 125 mm stroke is short enough to avoid guide requirements, but always check side loads.
Quick checklist
- ✓ Load to hold ≤ 2200 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 BSE63X125S FAQ
The lock is spring-applied and air-released. If air is lost, a collet clamps the rod, providing a 2200 N bidirectional static hold. It is a fail-safe holding device, not a dynamic brake; engage it only after the rod stops, and allow at least 0.5 s for release.
The 63 mm bore generates 1559 N push and 1402 N pull at 0.5 MPa, and 2182 N push at 0.7 MPa (max 222 kgf drive force). This drive force is separate from the 2200 N static holding force of the rod lock.
