Airtac BSED Clamping Double Acting Cylinder BSED80X700S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED80X700S 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, 700mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED80X700S
The AirTAC BSED80X700S is a double-acting, double-rod ISO 15552 profile cylinder equipped with an integrated spring-applied, air-released rod lock. A Ø25 mm rod exits both ends, delivering an equal drive force of 2268 N each way at 0.5 MPa. The rear rod is ideal for mounting flags or cams while resisting rotation. The fail-safe collet provides a 3600 N static holding force, clamping the rod securely if air pressure drops.
This extruded aluminum body features a 36 mm adjustable air cushion at both ends and operates at speeds from 30-800 mm/s. The -S magnet enables position sensing with CMSE reed or DMSE electronic switches. A separate G1/8 port releases the lock, requiring balanced pressure on both piston sides for safe disengagement.
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 BSED80X700S 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 BSED80X700S Is Used
Vertical Lift Stations
Lifts 324 kgf loads bidirectionally and clamps the rod with 3600 N of fail-safe holding force to prevent drops during an E-stop.
Pallet Stops
Uses the double-rod symmetry to stop heavy pallets equally from either direction while the lock holds the barrier rigid with no air.
Multi-Tool Machining
Mounts a cam on the rear rod for sensor feedback while the front rod strokes 700 mm, locking securely during tool changes.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X700S the Right Cylinder?
Select this 80 mm bore when an application requires both-way symmetric force (3175 N at 0.7 MPa) and fail-safe holding up to 3600 N. If your load requires less force, the 63 mm bore offers 1402 N at 0.5 MPa and 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. Ensure your load never exceeds the 3600 N static limit.
At 700 mm stroke, use a guide to prevent side-loading and protect the seal. Engage the lock only after the rod stops moving, and release it only when pressure is balanced, allowing at least 0.5 seconds. To replace this unit, match the 80 mm bore, 700 mm stroke, PT3/8 port, and -S magnet. Mounting options include Basic, LB, FA, and 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 BSED80X700S FAQ
The spring-applied collet engages automatically, providing a 3600 N static holding force to keep the rod at position. It is a fail-safe lock, not a dynamic brake, so it only engages after the rod stops moving. For overhead or man-rated loads, always use separate safety-rated controls.
The double-rod design provides equal force both ways: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a maximum drive force of 324 kgf. The integrated rod lock provides a separate 3600 N static holding force. Release the lock via the G1/8 port only after balancing pressure on both sides.
