Airtac BSE Clamp Standard Cylinder BSE63X450
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X450 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, 450mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X450
The AirTAC BSE63X450 is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. When air is exhausted or an E-stop trips, the collet clamps the Ø20 mm rod to deliver a 2200 N bidirectional fail-safe hold. The cylinder itself operates at 0.15-0.7 MPa, while a separate G1/8 release port unlocks the mechanism.
This 63 mm bore unit generates 1559 N push and 1402 N pull at 0.5 MPa, reaching a 2182 N peak drive force at 0.7 MPa. The lock is a static holding device, not a dynamic brake; it must engage only after the rod stops and release once pressures are balanced. This SKU lacks a magnet, meaning no CMSE or DMSE position sensors can be fitted. Standard SE mounting accessories fit this body, 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 BSE63X450 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 BSE63X450 Is Used
Vertical Palletizer Arm
Holds a 150 kg lifted pallet securely mid-stroke with 2200 N of fail-safe force if shop air drops suddenly, preventing a crash.
Pallet Flow Diverter
Locks the Ø20 mm rod in the extended position to block heavy pallet traffic, staying rigid during an E-stop with zero live air.
Fixture Clamp Station
Maintains clamping pressure on a machined housing using 2182 N of drive force, then locks the rod to prevent part movement on air loss.
Is the Airtac BSE Clamp Standard Cylinder BSE63X450 the Right Cylinder?
Verify your suspended load stays under the 2200 N static holding limit. If your load is lighter, the 50 mm bore provides 982 N push at 0.5 MPa with a 1400 N hold. For heavier demands, the 80 mm bore offers 2513 N push at 0.5 MPa and a 3600 N hold.
Always allow at least 0.5 seconds for full release before commanding motion. At 450 mm stroke, prevent side-loading by guiding the load externally. To replace this unit, match the 63 mm bore, 450 mm stroke, PT3/8 cylinder ports, and basic mounting.
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 BSE63X450 FAQ
The lock is spring-applied and fail-safe. If air is lost, exhausted, or an E-stop trips, the collet clamps the rod to provide a 2200 N bidirectional static hold with no live air.
Drive forces are 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a max 222 kgf drive at 0.7 MPa. The separate static holding force of the lock is 2200 N.
