Airtac BSE Clamp Standard Cylinder BSE63X80
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X80 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, 80mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X80
The AirTAC BSE63X80 is a double-acting single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It supplies 1559 N push force at 0.5 MPa, while a separate collet mechanism provides a 2200 N bidirectional static hold. Operating pressure is capped at 0.7 MPa, and a dedicated G1/8 release port governs the unlock function.
This fail-safe lock engages automatically if air is exhausted or an E-stop trips, holding the load firmly in place without live air. Because this SKU lacks a magnet, it does not support position sensing. The unit uses an extruded aluminum barrel and shares its mounting interface with the SE series, meaning SE accessories fit directly except for FTC.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X80 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 BSE63X80 Is Used
Vertical Lift Platforms
Holds a 2200 N raised payload securely on a 63 mm actuator if supply pressure drops, preventing sudden descent during pneumatic failure.
Machine Tool Clamps
Locks a workpiece with 1559 N drive force at 0.5 MPa, then relies on the collet to maintain grip during an emergency stop.
Pallet Stop Gates
Maintains a raised stop position on a packaging line using the fail-safe lock, ensuring the gate stays up if the main air supply is cut.
Is the Airtac BSE Clamp Standard Cylinder BSE63X80 the Right Cylinder?
Verify your suspended load stays below the 2200 N holding capacity. If your load is lighter, the adjacent 50 mm bore offers 982 N push at 0.5 MPa and a 1400 N hold; for heavier demands, the 80 mm bore provides 2513 N push at 0.5 MPa and a 3600 N hold. Always engage the collet only after the rod fully stops, and release it solely when piston pressures are balanced, allowing at least 0.5 seconds before moving. For exact replacements, match the 63 mm bore, 80 mm stroke, PT3/8 port, and specific mounting code.
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 BSE63X80 FAQ
The spring-applied collet clamps automatically on air loss, delivering a 2200 N bidirectional static hold. Drive forces are 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a maximum drive of 222 kgf.
No, you must release it only when pressures on both sides of the piston are balanced. Allow at least 0.5 seconds after supplying 0.15-0.7 MPa to the G1/8 release port before commanding movement.
