Airtac BSED Clamping Double Acting Cylinder BSED80X150
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED80X150 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, 150mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED80X150
The AirTAC BSED80X150 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A Ø25 mm rod exits both ends, delivering equal drive force of 2268 N each way at 0.5 MPa. This symmetric design provides 3175 N of thrust in both directions while resisting rotation.
The fail-safe collet mechanism provides a 3600 N static holding force without requiring live air. If pressure drops or an E-stop trips, the rod is securely clamped at position. It features a 36 mm adjustable air cushion at both ends, a PT3/8 cylinder port, and a dedicated G1/8 release port. This non-magnet SKU operates without 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 BSED80X150 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 BSED80X150 Is Used
Z-Axis Lift Gate
Holds a 300 kg vertical gate securely with 3600 N of fail-safe clamping force during air loss, while providing 3175 N of equal lifting and lowering thrust.
Dual-Tool Machining Jig
Uses the double-rod design to mount a secondary flag cam on the rear rod for anti-rotation, delivering 2268 N of symmetric clamping pressure at 0.5 MPa.
Pallet Divert Stopper
Locks the extended 25 mm rod instantly in place with no live air to halt heavy pallets, absorbing impact without relying on the 36 mm air cushion for static hold.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X150 the Right Cylinder?
Select this 80 mm bore when an application requires both-way symmetric force of 2268 N at 0.5 MPa and a 3600 N static hold. If your load is lighter, the 63 mm bore offers 1402 N drive force and a 2200 N hold; for heavier loads, the 100 mm bore provides 3681 N drive and a 5500 N hold. Always verify the load is under 3600 N.
Engage the lock only after the rod completely stops, and release it only when piston sides are pressure-balanced, allowing at least 0.5 seconds. To match this cylinder for replacement, confirm the 150 mm stroke, PT3/8 port, and Basic, LB, FA, or TC mounting. Since the 150 mm stroke is under 300 mm, standard side-load concerns are minimal, but always ensure axial alignment.
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 BSED80X150 FAQ
This double-rod cylinder provides equal drive force in both directions: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa (max 324 kgf). The integrated fail-safe rod lock provides a separate bidirectional static holding force of 3600 N with no live air required.
The spring-applied collet engages automatically when air is lost. To release it safely, ensure both piston sides are pressure-balanced, apply air to the dedicated G1/8 release port, and wait at least 0.5 seconds before commanding motion. The lock is a static hold, not a dynamic brake.
