Airtac BSE Clamp Standard Cylinder BSE63X115S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X115S 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, 115mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE63X115S
The AirTAC BSE63X115S is a double-acting ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. It provides a 2200 N bidirectional static holding force with no live air, ensuring suspended loads stay put if pressure drops or an E-stop trips. Operating pressure is capped at 0.7 MPa.
This model features a Ø20 mm rod, M16x1.5 thread, and a PT3/8 cylinder port. The lock uses a separate G1/8 release port and is strictly a static hold, not a dynamic brake. You must engage the lock only after the rod stops and release it only when piston pressures are balanced, allowing at least 0.5 seconds before moving. The -S magnet supports CMSE reed and DMSE electronic sensors.
Rod Lock — 2200 N Static Holding (Ø63mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X115S 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 BSE63X115S Is Used
Vertical Pallet Lift
Holds a 2200 N vertical pallet lift firmly in place during an E-stop or air loss, preventing sudden drops and protecting goods below.
Clamping Fixture
Secures an automotive machining fixture with 2182 N of drive force, then locks the rod to maintain exact clamp pressure without bleeding air.
Pallet Stop Gate
Blocks a 63 mm conveyor stop gate using 1559 N push at 0.5 MPa, engaging the 2200 N fail-safe collet so the gate stays shut if air fails.
Is the Airtac BSE Clamp Standard Cylinder BSE63X115S the Right Cylinder?
Verify your load does not exceed the 2200 N holding force. If you need less force, the 50 mm bore offers 982 N push at 0.5 MPa and a 1400 N hold. For heavier loads, the 80 mm bore provides 2513 N push at 0.5 MPa and a 3600 N hold. Always engage the lock only after the rod fully stops, and release it only when pressures are balanced, waiting 0.5 seconds.
This 115 mm stroke is under 300 mm, so side-load risks are minimal, but proper guiding is still recommended. When replacing a unit, match the 63 mm bore, 115 mm stroke, PT3/8 port, and -S magnet. Standard SE mounting accessories fit this cylinder 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 BSE63X115S FAQ
The lock is spring-applied and air-released. If air is lost, a collet clamps the rod, providing a 2200 N bidirectional static hold. It is a fail-safe hold, not a dynamic brake, so you must engage it only after the rod stops.
The drive force is 1559 N push at 0.5 MPa, 1402 N pull at 0.5 MPa, and 2182 N push at 0.7 MPa, equating to 222 kgf max drive. The separate static holding force of the lock is 2200 N.
