Airtac BSE Clamp Standard Cylinder BSE63X300S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X300S 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, 300mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X300S
The AirTAC BSE63X300S 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 remain exactly where they stopped if air pressure drops or an E-stop trips. Operating pressure is capped at 0.7 MPa, and the cylinder port is PT3/8.
This 63mm bore, 300mm stroke variant includes a magnet for position sensing. The lock uses a separate G1/8 release port to unlock the clamping collet. Remember that the lock is a static holding device, not a dynamic brake; it must only engage after the piston stops, and you must allow at least 0.5 s for full release before commanding motion.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X300S 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 BSE63X300S Is Used
Vertical Pallet Lift
Holds a raised pallet stack securely with 2200 N of fail-safe force during air loss, preventing sudden drops while the 1559 N push drive handles the lift.
Spindle Head Clamp
Locks a machining head in its retracted position on E-stop. The collet engages instantly without live air, keeping the 20mm rod rigid during tool changes.
Pallet Stop Gate
Acts as a fail-safe stop on an assembly line. The 2200 N hold keeps the gate rigid against impacts, while the 1402 N pull drive retracts it smoothly.
Is the Airtac BSE Clamp Standard Cylinder BSE63X300S the Right Cylinder?
Verify your load requires 2200 N or less of holding force. If you need less drive and hold, the 50mm bore neighbor offers 982 N push at 0.5 MPa and 1400 N hold. If your load exceeds this unit, stepping up to the 80mm bore provides 2513 N push at 0.5 MPa and 3600 N hold. Always balance pressures on both sides of the piston before releasing the lock.
At 300mm stroke, guide the load to prevent excessive side-loading on the rod. This BSE63X300S includes the -S magnet for CMSE reed and DMSE electronic sensors. SE mounting accessories fit this ISO 15552 body perfectly, except FTC. When replacing, match the 63mm bore, 300mm stroke, PT3/8 port, and basic mounting.
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 BSE63X300S FAQ
If air is lost, a spring applies a clamping collet to the rod, providing a 2200 N bidirectional static hold. The drive forces are separate: push is 1559 N at 0.5 MPa, pull is 1402 N at 0.5 MPa, push is 2182 N at 0.7 MPa, max drive is 222 kgf.
The lock is spring-applied and air-released via a separate G1/8 port. You must first balance the air pressures on both sides of the piston, then supply 0.15-0.7 MPa to the release port, and wait at least 0.5 seconds before moving the cylinder to avoid damaging the collet.
