About the Airtac BSED Clamping Double Acting Cylinder BSED80X900
The AirTAC BSED80X900 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, yielding equal drive force of 2268 N each way at 0.5 MPa and 3175 N at 0.7 MPa. The fail-safe collet provides a 3600 N static holding force, clamping the rod securely during air loss or E-stop events.
This 80 mm bore unit runs at 30-800 mm/s with a PT3/8 cylinder port and a dedicated G1/8 lock-release port. The rear rod supports tooling or flags while resisting rotation. This SKU has no -S magnet, meaning no position sensing is available without adding a magnet. Engage the lock only after the rod stops, and release it only when both piston sides are pressure-balanced.
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 BSED80X900 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 |
| Max drive (@0.7 MPa) | 324 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 3600 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED80X900 Is Used
Vertical Lift Stations
Holds a 300 kgf vertical load securely at 900 mm height with its 3600 N fail-safe lock, while delivering 3175 N of equal both-way drive force for smooth up/down cycles.
Dual-End Tooling Press
Uses the rear rod for a cam flag while the front rod presses with 2268 N at 0.5 MPa, engaging the collet lock only after the press motion fully stops.
Pallet Diverter Arm
Extends a long 900 mm stroke to sort heavy pallets, relying on the bidirectional 3175 N drive and the spring-applied lock to prevent drift during E-stops.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X900 the Right Cylinder?
Select this 900 mm stroke model when your application needs both symmetric thrust and a reliable fail-safe hold. Verify your static load is 3600 N or less. If you need less force, the 63 mm bore offers 1402 N at 0.5 MPa and a 2200 N hold; if you need more, the 100 mm bore provides 3681 N at 0.5 MPa and a 5500 N hold. Because the 900 mm stroke is long, always use external guide rails to prevent side-loading and seal wear. To replace, match the 80 mm bore, 900 mm stroke, PT3/8 port, and mounting style (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 BSED80X900 FAQ
The integrated spring-applied collet immediately clamps the rod, providing a 3600 N static holding force to prevent movement. It is a fail-safe lock, not a dynamic brake, so it must only engage after the rod stops. To release it, apply pressure to the G1/8 port only after both piston sides are balanced.
The drive force is equal both ways: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a max drive of 324 kgf. The separate static holding force of the rod lock is 3600 N. Operating pressure is capped at 0.7 MPa.
