About the Airtac BSED Clamping Double Acting Cylinder BSED80X700
The AirTAC BSED80X700 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, delivering equal drive force of 2268 N each way at 0.5 MPa and 3175 N at 0.7 MPa. The bidirectional collet lock provides a 3600 N static holding force with zero live air required.
This 80 mm bore unit has a 700 mm stroke, a PT3/8 cylinder port, and a separate G1/8 lock-release port. It features a 25 mm rod with an M20x1.5 thread, 36 mm adjustable air cushions at both ends, and operates at 30-800 mm/s. This specific SKU lacks a magnet, so CMSE or DMSE position sensors cannot be used.
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 BSED80X700 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 BSED80X700 Is Used
Overhead Z-Axis Lifts
Uses the 3175 N equal both-way force to raise and lower heavy gates, while the 3600 N fail-safe collet locks the rod instantly if compressed air is lost, preventing uncontrolled drops.
Pallet Transfer Stops
The dual-end rod allows a flag cam to mount on the rear for confirmation, while the spring-applied lock holds the 80 mm stopper blade rigid against accumulating line pressure.
Multi-Position Machining Stops
Provides identical clamping tension in both advance and retract directions, engaging the 3600 N hold only after the workpiece comes to a complete stop to avoid dynamic braking damage.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X700 the Right Cylinder?
Select this 80 mm model when an application requires symmetric pushing/pulling force alongside a 3600 N fail-safe holding capacity. If your load demands less force, the 63 mm bore offers 1402 N at 0.5 MPa with a 2200 N hold; if you need more, step up to the 100 mm bore providing 3681 N at 0.5 MPa and a 5500 N hold. Always ensure the load is stopped before engaging the lock, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds.
With a 700 mm stroke, external guide rails are recommended to manage side loads and prevent rod binding. When replacing a unit, match the 80 mm bore, 700 mm stroke, PT3/8 port, and mounting style (Basic, LB, FA, or TC). Since this specific SKU has no magnet, position sensing is unavailable.
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 BSED80X700 FAQ
The integrated collet is spring-applied, so it automatically clamps the rod, providing a 3600 N static holding force to keep the load in position. It is a fail-safe hold, not a dynamic brake, so it must only be engaged after the rod has stopped moving.
The drive force is equal both ways at 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a maximum drive force of 324 kgf. The static holding force of the lock is 3600 N, which is separate from the drive force and requires no live air to maintain.
