Airtac BSE Clamp Standard Cylinder BSE63X700
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X700 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, 700mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X700
The AirTAC BSE63X700 is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It provides a robust bidirectional fail-safe holding force of 2200 N. If air pressure drops or an E-stop trips, the collet clamps the piston rod instantly, holding the load securely in place without consuming live air.
Operating pressure is capped at 0.7 MPa, and the lock releases via a separate G1/8 port. The unit uses an extruded aluminum barrel without external tie rods. This specific SKU lacks a magnet, so it does not support CMSE or DMSE position sensors.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X700 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 BSE63X700 Is Used
Vertical Pallet Lift
Holds a raised pallet stack securely with 2200 N of fail-safe force, preventing a crash if the shop air supply suddenly exhausts.
Machining Center Door
Locks the heavy 700 mm stroke safety door closed during spindle operation, keeping the barrier rigid even during an E-stop.
Pallet Stopper Gate
Acts as a hardened stop on an assembly line. The spring-applied collet ensures the 63 mm rod stays extended if control voltage fails.
Is the Airtac BSE Clamp Standard Cylinder BSE63X700 the Right Cylinder?
Verify your suspended load requires 2200 N or less of holding force. If you need less drive and hold, step down to the 50 mm bore, which offers 982 N push at 0.5 MPa and a 1400 N hold. If your load exceeds this unit, step up to the 80 mm bore, providing 2513 N push at 0.5 MPa and a 3600 N hold.
The lock is not a dynamic brake; engage it only after the rod stops completely. Release it only when pressures on both sides of the piston are balanced, allowing at least 0.5 s before moving. Because the 700 mm stroke is long, use external guide rails to prevent side loads from damaging the rod seals. To replace this cylinder, match the 63 mm bore, 700 mm stroke, PT3/8 port, and mounting. 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 BSE63X700 FAQ
The spring-applied collet provides a 2200 N static holding force in both directions with no live air. The drive forces are separate: 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a maximum 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 to avoid sudden shifting, and wait at least 0.5 s for full release before commanding cylinder movement.
