Airtac BSED Clamping Double Acting Cylinder BSED80X900S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED80X900S combines a double-rod ISO 15552 cylinder — a Ø25mm rod out BOTH ends for equal force both directions — with an integrated spring-applied, air-released ROD LOCK that holds up to 3600 N in either direction if air is lost. Ø80mm bore, 900mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED80X900S
The AirTAC BSED80X900S is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, providing equal drive force of 2268 N each way at 0.5 MPa and 3175 N at 0.7 MPa. The rear rod is ideal for mounting flags or anti-rotation tooling.
This fail-safe collet lock delivers a 3600 N static holding force with no live air required. It engages only after the rod stops and releases via a dedicated G1/8 port once piston sides are pressure-balanced. The extruded aluminum body has no external tie rods, and the included -S magnet supports CMSE reed and DMSE electronic 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 BSED80X900S 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.

Specifications follow the official AirTAC BSED datasheet. Rod thread M20×1.5 both ends. Mounting (BSED): Basic, LB, FA, TC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
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 BSED80X900S Is Used
Elevator Hoist Interlock
Holds a 300 kg vertical lift carriage securely mid-stroke with 3600 N of fail-safe force, while the 3175 N both-way drive ensures smooth upward and downward motion.
Heavy-Duty Indexing Slide
Uses the double-rod design for anti-rotation during machining stops, engaging the collet lock to resist 3600 N of cutting force without needing live air.
Pallet Divertor Gate
Employs the equal both-way 3175 N drive to push heavy pallets left and right, locking the gate open during E-stops to prevent accidental closures.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X900S the Right Cylinder?
Choose this 80 mm bore when an application requires symmetric 3175 N drive force and 3600 N static holding. If your load is lighter, the 63 mm bore offers 1402 N at 0.5 MPa and 2200 N holding; for heavier demands, the 100 mm bore provides 3681 N at 0.5 MPa and 5500 N holding. Always verify your load is under 3600 N.
At 900 mm stroke, add an external guide to prevent side-load sagging on the rod. Engage the lock only when stopped, and allow at least 0.5 s for release. To match this unit for replacements, confirm the 80 mm bore, 900 mm stroke, PT3/8 cylinder port, and -S magnet.
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 BSED80X900S FAQ
If air is lost, the spring-applied collet immediately clamps the rod, providing a 3600 N static holding force to keep the load in place. It is a fail-safe lock, not a dynamic brake, so it must only be engaged after the rod has stopped moving.
The double-rod drive force is equal both ways at 2268 N at 0.5 MPa and 3175 N at 0.7 MPa (max 324 kgf). The static holding force of the lock is 3600 N. Operating pressure is 0.15-0.7 MPa, and speed ranges from 30-800 mm/s.
