Airtac BSE Clamp Standard Cylinder BSE63X50S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X50S 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, 50mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X50S
The AirTAC BSE63X50S is a double-acting single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It provides a robust 2200 N bidirectional static holding force, ensuring suspended loads stay exactly where they stopped if air pressure drops. Operating pressure is capped at 0.7 MPa.
This 63 mm bore, 50 mm stroke unit uses a separate G1/8 release port to unlock the internal collet. The -S magnet enables position detection with CMSE reed or DMSE electronic sensors. Remember to engage the lock only after the rod fully stops and allow at least 0.5 s for pressure balancing before releasing.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X50S 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 BSE63X50S Is Used
Vertical Pallet Lift
Holds a raised pallet handler stationary at 1559 N push drive force, engaging the 2200 N fail-safe collet to prevent gravity drift during an E-stop.
Tooling Clamp
Secures a machining fixture in place; the spring-applied lock maintains the clamp position without consuming live air during the cutting cycle.
Pallet Stop Gate
Acts as a mid-conveyor stop gate that remains firmly extended and locked at 2200 N if the compressed air supply is suddenly exhausted.
Is the Airtac BSE Clamp Standard Cylinder BSE63X50S the Right Cylinder?
Verify your load requires 2200 N or less of holding force. If your application needs less drive power, the 50 mm bore neighbor offers 982 N push at 0.5 MPa and 1400 N holding force. If you need heavier suspension capacity, stepping up to the 80 mm bore provides 2513 N push at 0.5 MPa and 3600 N holding force.
When replacing, match the 63 mm bore, 50 mm stroke, PT3/8 cylinder port, and M16x1.5 rod thread. SE mounting accessories fit this body perfectly except FTC. Because the 50 mm stroke is short, side-load risks are minimal, but always ensure the load is balanced before actuating the lock.
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 BSE63X50S FAQ
The spring-applied collet engages automatically upon air loss, delivering a 2200 N static holding force. The drive forces are separate: push is 1559 N and pull is 1402 N at 0.5 MPa, push is 2182 N at 0.7 MPa, with a max drive of 222 kgf.
You must supply 0.15-0.7 MPa to the separate G1/8 release port. Ensure the pressures on both sides of the piston are balanced first, then allow at least 0.5 seconds for the collet to fully release before commanding cylinder movement.
