Airtac BSE Clamp Standard Cylinder BSE80X50
The AirTAC Airtac BSE Clamp Standard Cylinder BSE80X50 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 Ø25mm rod and holds up to 3600 N in either direction — no drift. Ø80mm bore, 50mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE80X50
The AirTAC BSE80X50 is a double-acting ISO 15552 profile cylinder featuring a spring-applied, air-released collet rod lock. It supplies a bidirectional static holding force of 3600 N with no live air required, firmly clamping the Ø25 mm rod if pressure drops or an E-stop trips. Operating pressure is capped at 0.7 MPa, and speed spans 30-800 mm/s.
This unit uses a separate G1/8 release port to overcome the spring and free the rod. The lock is a holding device, not a dynamic brake; engage it only after the piston stops, balance pressures on both sides, and allow at least 0.5 s before moving. Standard SE mounting accessories fit this body, except FTC.
Rod Lock — 3600 N Static Holding (Ø80mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE80X50 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.

| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 36 mm |
| Max stroke | Up to 1000 mm |
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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa (max) | 3519 N | — |
| Max drive (@0.7 MPa) | 359 kgf | |
Drive force is separate from the 3600 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 BSE80X50 Is Used
Vertical Pallet Lifters
Holds a 3600 N vertical load in place instantly if shop air exhausts, preventing pallet drops during mid-stroke power loss.
Press Tool Clamping
Keeps a heavy stamping tool clamped securely with zero live air, ensuring the tool cannot drift or release during an E-stop.
Pallet Stop Gate
Locks the 25 mm rod to form a rigid stop for heavy conveyor traffic, maintaining its position without relying on continuous air pressure.
Is the Airtac BSE Clamp Standard Cylinder BSE80X50 the Right Cylinder?
Verify your suspended load stays under the 3600 N holding force. If your load is lighter, a BSE63X50 offers 1559 N push at 0.5 MPa and a 2200 N hold; if you need more stopping security, a BSE100X50 provides 3927 N push at 0.5 MPa and a 5500 N hold. Because the 50 mm stroke is short, side-load stress is minimal, but always guide external weights rather than relying on the rod.
Match the exact replacement by confirming the PT3/8 cylinder port, M20x1.5 rod thread, and 36 mm cushion length. This specific SKU lacks the -S magnet, so it cannot host CMSE or DMSE position sensors. To release safely, apply 0.15-0.7 MPa to the G1/8 release port only after balancing the piston pressures.
Quick checklist
- ✓ Load to hold ≤ 3600 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 BSE80X50 FAQ
The drive force is 2513 N push and 2268 N pull at 0.5 MPa, or 3518 N push at 0.7 MPa (max 359 kgf). The separate static rod-lock holding force is 3600 N.
The spring-applied collet clamps the rod instantly, providing a 3600 N bidirectional fail-safe hold. To release it, restore air to the G1/8 port, balance piston pressures, and wait 0.5 s before moving.
