Airtac BSE Clamp Standard Cylinder BSE63X250
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X250 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, 250mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X250
The AirTAC BSE63X250 is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It delivers a 2200 N bidirectional static holding force with no live air, securely clamping the Ø20 mm piston rod via a collet mechanism whenever pressure drops or an E-stop trips. Operating pressure is capped at 0.7 MPa.
This 63 mm bore unit provides 1559 N push force at 0.5 MPa and uses adjustable air cushions at both ends. The lock operates via a separate G1/8 release port, requiring 0.15-0.7 MPa to unlock. This specific SKU lacks a magnet, so it does not support CMSE or DMSE position sensors.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X250 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 | — |

Where the Airtac BSE Clamp Standard Cylinder BSE63X250 Is Used
Vertical Machining Center Z-Axis
Holds a 150 kg tooling head mid-stroke. The 2200 N fail-safe collet prevents gravity drops during an air loss event, while the 2182 N push drive handles the machining feed.
Pallet Transfer Stop Gate
Acts as a rigid stop for heavy pallets. The spring-applied lock clamps instantly on E-stop, keeping the gate locked with 2200 N force even with no air supply.
Automated Welding Fixture
Maintains exact clamp position on a 63 mm bore actuator. The collet holds the part securely against vibration, preventing drift without consuming continuous air.
Is the Airtac BSE Clamp Standard Cylinder BSE63X250 the Right Cylinder?
Verify your suspended load requires 2200 N or less of holding force. If you need less drive and hold, the 50 mm bore offers 982 N push at 0.5 MPa and 1400 N holding force. If your application demands more, step up to the 80 mm bore, which provides 2513 N push at 0.5 MPa and 3600 N holding force. Always engage the lock only after the rod fully stops, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving.
To replace this unit, match the 63 mm bore, 250 mm stroke, PT3/8 cylinder port, and your specific SE-compatible mounting choice (excluding FTC). Because the 250 mm stroke exceeds 300 mm is false here, standard side-load rules apply, but always ensure adequate guiding for the rod end M16x1.5 thread.
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 BSE63X250 FAQ
The lock is spring-applied and air-released. If air is lost, a collet automatically clamps the rod, providing a 2200 N bidirectional static holding force. It is not a dynamic brake; engage it only after the rod stops, and allow at least 0.5 s for full release via the G1/8 port before moving.
At 0.5 MPa, push force is 1559 N and pull is 1402 N. At the 0.7 MPa ceiling, push is 2182 N, yielding a max drive of 222 kgf. The separate static holding force of the lock is 2200 N.
