Airtac BSE Clamp Standard Cylinder BSE63X400
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X400 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, 400mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X400
The AirTAC BSE63X400 is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the 20 mm piston rod, providing a 2200 N bidirectional static holding force with zero live air. If air exhausts or an E-stop trips, the rod is held exactly where it stopped.
Operating pressure is capped at 0.15-0.7 MPa, and a separate G1/8 release port unlocks the mechanism. The lock is a fail-safe hold, not a dynamic brake. Engage it only after the rod stops, balance pressures on both sides of the piston, and allow at least 0.5 s for full release before moving. This unit has no magnet, so position sensors are not supported.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X400 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 (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 BSE63X400 Is Used
Vertical Lift Gate
Holds a 150 kg vertical lift gate securely mid-stroke during air loss, using the 2200 N fail-safe collet to prevent uncommanded descent.
Machine Tool Clamp
Maintains clamping force on a machined part if shop air drops, preventing the 1559 N drive force from releasing the part unexpectedly.
Pallet Stopper Arm
Locks a 400 mm stroke stopper arm rigid in the extended path during E-stop, withstanding impact drift via the bidirectional collet hold.
Is the Airtac BSE Clamp Standard Cylinder BSE63X400 the Right Cylinder?
Verify your suspended load stays under the 2200 N holding force. If you need less drive, the 50 mm bore gives 982 N push at 0.5 MPa and 1400 N hold. For heavier suspension, the 80 mm bore provides 2513 N push at 0.5 MPa and 3600 N hold. Match replacement parts by 63 mm bore, 400 mm stroke, PT3/8 port, and mounting style. SE mounting accessories fit this body perfectly, except FTC.
At 400 mm stroke, side-load risks increase. Guide the load externally to prevent rod bending and premature seal wear. Always engage the lock only after the load fully stops to avoid damaging the clamping collet.
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 BSE63X400 FAQ
A spring-applied collet provides a 2200 N static holding force in both directions with no live air. The drive force is 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, with a maximum drive of 222 kgf. Holding and drive forces are separate.
Balance the air pressures on both sides of the piston first. Then supply 0.15-0.7 MPa to the separate G1/8 release port. Wait at least 0.5 s for full release before commanding movement, as engaging the lock dynamically while moving will damage the collet.
