Airtac BSE Clamp Standard Cylinder BSE63X450S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X450S 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 BSE63X450S
The AirTAC BSE63X450S 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 no live air. If air drops or an E-stop trips, the rod stays put. Operating pressure is capped at 0.7 MPa.
This 63 mm bore, 450 mm stroke model includes a magnet for CMSE reed and DMSE electronic sensors. It features a PT3/8 cylinder port and a separate G1/8 release port. The lock is a holding device, not a dynamic brake; engage it only after the rod stops and allow at least 0.5 s for full release before moving.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X450S 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 BSE63X450S Is Used
Vertical Lift Doors
Holds a 2200 N vertical door in place during air loss, preventing gravity drops while the 2182 N drive moves the load.
Spindle Clamp
Secures a machining spindle mid-cycle; the fail-safe collet maintains the position if the 0.7 MPa supply exhausts.
Pallet Stopper
Acts as an emergency stop for 63 mm conveyor lanes, locking the rod instantly on E-stop to halt pallet flow.
Is the Airtac BSE Clamp Standard Cylinder BSE63X450S the Right Cylinder?
Verify your suspended load needs 2200 N or less of holding force, distinct from the 2182 N push drive at 0.7 MPa. If you need less force, the 50 mm bore offers 982 N push at 0.5 MPa and 1400 N hold. If you need more, step up to the 80 mm bore for 2513 N push at 0.5 MPa and 3600 N hold.
At 450 mm stroke, use a guide to prevent side loads from damaging the seals. To replace, match the 63 mm bore, 450 mm stroke, PT thread, and -S magnet. SE mounting accessories fit this body except FTC.
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 BSE63X450S FAQ
The spring-applied collet clamps the rod, providing a 2200 N bidirectional static hold with no live air. It is a holding lock, not a dynamic brake; engage it only after the rod stops, and balance pressures before releasing.
Drive force at 0.5 MPa is 1559 N push and 1402 N pull. At 0.7 MPa, push is 2182 N (max 222 kgf). The separate static holding force of the rod lock is 2200 N.
