Airtac BSE Clamp Standard Cylinder BSE63X75S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X75S 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, 75mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X75S
The AirTAC BSE63X75S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A collet clamps the 20 mm rod to deliver a 2200 N bidirectional holding force. If air is lost or an E-stop trips, the rod is held safely in place. Operating pressure is capped at 0.7 MPa.
This 63 mm bore unit features a separate G1/8 release port that unlocks the collet. The lock is a holding device, not a dynamic brake. You must engage it only after the rod stops and release it only when piston pressures are balanced, allowing at least 0.5 s for full release before moving. The -S magnet supports CMSE and DMSE sensors.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X75S 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 BSE63X75S Is Used
Vertical Lift Hold
Secures a 1500 N vertical lifting stage on packaging equipment, preventing uncommanded drops during an air loss event.
Tool Clamp Lock
Holds a machining fixture clamp firmly in position, ensuring the tool does not shift when the main air supply is exhausted.
Gate Stop Position
Maintains a heavy conveyor diverter gate at a set position during an emergency stop, resisting 1800 N of reversing product force.
Is the Airtac BSE Clamp Standard Cylinder BSE63X75S the Right Cylinder?
Verify your load stays below the 2200 N static holding force. If you need less drive force, the 50 mm bore offers 982 N push at 0.5 MPa and a 1400 N hold. If you need more, the 80 mm bore gives 2513 N push at 0.5 MPa and a 3600 N hold.
When ordering a replacement, match the 63 mm bore, 75 mm stroke, PT3/8 cylinder port, and the -S magnet option. SE mounting accessories fit this ISO 15552 body perfectly, except for FTC. Remember to engage the lock only after the rod stops, and release it only when pressures are balanced.
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 BSE63X75S FAQ
The spring-applied collet engages automatically on air loss to provide a 2200 N static holding force. The drive force is 1559 N push at 0.5 MPa, 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a max drive of 222 kgf.
The lock is a holding device, not a dynamic brake. You must engage it only after the rod stops, and release it only when both sides of the piston are pressure-balanced. Allow at least 0.5 s after supplying 0.15-0.7 MPa to the G1/8 release port before moving.
