Airtac BSE Clamp Standard Cylinder BSE63X250S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X250S 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, 250mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X250S
The AirTAC BSE63X250S is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a 2200 N bidirectional static holding force with no live air, ensuring suspended loads stay exactly where they stopped if air pressure drops. Operating pressure is capped at 0.7 MPa, and the cylinder runs at speeds from 30-800 mm/s.
This 63 mm bore, 250 mm stroke variant includes a magnet for CMSE or DMSE sensors. Unlocking requires 0.15-0.7 MPa supplied to the separate G1/8 release port. The collet lock engages only after the piston stops, providing true fail-safe drift protection rather than dynamic braking.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X250S 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 BSE63X250S Is Used
Palletizer Lift Arm
Secures vertical lift arms carrying heavy pallets. The 2200 N holding force locks the 250 mm stroke instantly on E-stop, preventing uncontrolled drops when main air is exhausted.
CNC Tooling Clamp
Holds machining fixtures in place during sudden pressure loss. The spring-applied collet maintains 222 kgf of drive force positioning while locking the rod bidirectionally.
Sortation Diverter Gate
Keeps heavy package diverter gates fixed in position during conveyor pauses. The fail-safe lock ensures the gate stays put, avoiding product jams when air supply fluctuates.
Is the Airtac BSE Clamp Standard Cylinder BSE63X250S the Right Cylinder?
Verify your load stays under the 2200 N holding force. If your load is lighter, the 50 mm bore offers 982 N push at 0.5 MPa and 1400 N holding force. If you need more stopping power, step up to the 80 mm bore, providing 2513 N push at 0.5 MPa and 3600 N holding force. Always balance pressures on both sides of the piston before unlocking, allowing at least 0.5 s for full release.
For this 250 mm stroke, use a guide rail to prevent side-load damage to the seals. This BSE63X250S configuration uses a PT3/8 cylinder port, a G1/8 release port, and an M16x1.5 rod thread. SE mounting accessories fit perfectly except FTC. The -S suffix means it is ready for CMSE reed and DMSE electronic sensors.
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 BSE63X250S FAQ
The lock is spring-applied and air-released. If air is lost, a collet clamps the rod, providing a 2200 N static holding force in both directions. The drive forces are 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a max drive of 222 kgf.
You must ensure the rod has completely stopped moving and the pressures on both sides of the piston are balanced. Then supply 0.15-0.7 MPa to the separate G1/8 release port, allowing at least 0.5 seconds for the collet to fully release before commanding cylinder movement.
