About the Airtac BSED Clamping Double Acting Cylinder BSED80X350
The AirTAC BSED80X350 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 in both directions at 2268 N each way at 0.5 MPa. The extruded aluminum body provides ISO 15552 mounting interchangeability without external tie rods.
This fail-safe collet lock delivers a 3600 N static holding force with no live air. It engages bidirectionally to secure your load, while the rear rod allows mounting a flag or cam and resists rotation. This unit has no magnet, meaning no position sensing on this SKU.
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 BSED80X350 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 BSED80X350 Is Used
Overhead Lift Dwell
Holds a 350 kg lifted pallet securely at dwell using the 3600 N lock, while the 3175 N both-way drive raises and lowers the platform.
Multi-Station Machining
Shifts a machining fixture between stations with equal 2268 N push/pull force, clamping the rod during cutting to resist vibration.
Pallet Stop Gate
Acts as a heavy conveyor stop gate; the double-rod design resists rotation, and the fail-safe lock holds the barrier if air drops.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X350 the Right Cylinder?
Choose this 80 mm bore when you need both-way symmetric force of 2268 N at 0.5 MPa alongside a 3600 N static fail-safe hold. If your load requires less force, the 63 mm bore offers 1402 N drive and 2200 N holding; if you need more, step up to the 100 mm bore providing 3681 N drive and 5500 N holding. Always verify your load is under 3600 N.
Engage the lock only after the rod stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 s. With a 350 mm stroke, use a guide to prevent side loads. For replacements, match the 80 mm bore, 350 mm stroke, PT3/8 port, and mounting style.
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 BSED80X350 FAQ
This cylinder delivers a drive force of 2268 N at 0.5 MPa and 3175 N at 0.7 MPa (max 324 kgf), equal in both directions. The integrated spring-applied rod lock provides a 3600 N static holding force.
If air is lost or an E-stop trips, the spring-applied collet clamps the rod, holding the load up to 3600 N. To release safely, ensure both piston sides are pressure-balanced and apply air to the G1/8 release port for at least 0.5 s.
