About the Airtac BSED Clamping Double Acting Cylinder BSED80X175
The AirTAC BSED80X175 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. Because a rod exits both ends, it delivers equal drive force in both directions—2268 N each way at 0.5 MPa—while resisting torsional rotation. The rear rod can simultaneously drive a tool and actuate a cam or flag.
A bidirectional collet provides a 3600 N static holding force with no live air required. If air pressure drops or an E-stop trips, the lock engages to hold the load safely in place. This unit uses a PT3/8 cylinder port, a separate G1/8 release port, and adjustable air cushions at both ends. Note that this specific SKU lacks a magnet, so it does not support CMSE or DMSE position sensors.
Double Rod + 3600 N Rod Lock (Ø80mm)
A rod exits both ends for symmetric force and back-rod tooling, and a spring clamps the collet so the Airtac BSED Clamping Double Acting Cylinder BSED80X175 holds its position in both directions on air loss or E-stop. Apply 0.15–0.7 MPa to the G1/8 release port to unlock. Engage only after the rod has stopped (not a dynamic brake), and release only when both piston sides are pressure-balanced; allow ≥0.5 s for full release.

Theoretical Output Force (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa (max) | 3175 N |

Where the Airtac BSED Clamping Double Acting Cylinder BSED80X175 Is Used
Vertical Lift Platforms
Raises and lowers 300 kg work platforms with 3175 N of equal both-way force, engaging the 3600 N rod lock to prevent gravity drops during loading.
Dual-Tool Machining Jigs
Uses the double-rod design to mount opposing tools, delivering 2268 N of symmetric thrust while the fail-safe collet holds the exact machining position.
Pallet Diverters
Shifts heavy pallets horizontally on a 175 mm stroke, relying on the 3600 N static hold to lock the diverter blade securely between cycles.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X175 the Right Cylinder?
Select this 80 mm bore model when your application requires symmetric thrust (3175 N at 0.7 MPa) and a robust fail-safe hold up to 3600 N. If your load requires less force, the 63 mm bore offers 1402 N at 0.5 MPa and a 2200 N holding force. For heavier demands, stepping up to the 100 mm bore provides 3681 N at 0.5 MPa and a 5500 N holding capacity.
Always verify your load stays within the 3600 N static limit. Engage the lock only after the rod completely stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the transition. When replacing a unit, match the 175 mm stroke, PT3/8 porting, and mounting choice (Basic, LB, FA, or TC).
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 3600 N?
- ✓ Back-rod space for tooling/flag
- ✓ Lock engaged only when stopped
- ✓ G1/8 release-air line available
Installation & Safety Notes
- check Engage the lock only after the rod has stopped — not 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 Support both rod ends; avoid side load.
- check Use BSED mounting (Basic/LB/FA/TC).
Airtac BSED Clamping Double Acting Cylinder BSED80X175 FAQ
The integrated rod lock is spring-applied and air-released. If air is lost or an E-stop is activated, the collet immediately clamps the 25 mm rod, providing a 3600 N static holding force to keep the load in position. It is a static lock, not a dynamic brake, so it must only be engaged after the rod stops moving.
The double-rod design provides equal force both ways: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a maximum drive force of 324 kgf. This drive force is separate from the 3600 N static holding force of the fail-safe rod lock.
