Airtac BSED Clamping Double Acting Cylinder BSED100X80S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X80S 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 5500 N in either direction if air is lost. Ø100mm bore, 80mm stroke, PT1/2 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED100X80S
The AirTAC BSED100X80S 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 force in both directions—3681 N each way at 0.5 MPa. The fail-safe collet lock provides a 5500 N static holding force, securing the load entirely with no live air.
This 100 mm bore unit includes a -S magnet for CMSE reed or DMSE electronic sensors. It features a PT1/2 cylinder port, a separate G1/8 lock-release port, and a 36 mm adjustable air cushion at both ends. The lock engages only after the rod stops and releases when both piston sides are pressure-balanced.
Double Rod + 5500 N Rod Lock (Ø100mm)
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 BSED100X80S 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 (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa (max) | 5154 N |
| Max drive (@0.7 MPa) | 526 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 5500 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED100X80S Is Used
Overhead Z-Axis Lifts
Secures vertical lifting stages during air loss or E-stop, relying on the 5500 N holding force to prevent drops while the 5153 N both-way drive handles the lift cycle.
Multi-Position Machining
Uses the double-rod design for equal machining pressure on both strokes and clamps the 25 mm rod instantly when the spindle retracts, ensuring zero drift.
Heavy Pallet Stops
Halts heavy pallets with symmetric push/pull capability, then the fail-safe lock holds the 525 kgf load firmly in place without consuming continuous air.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X80S the Right Cylinder?
Select the BSED100X80S when your application demands symmetric drive power and immediate fail-safe holding. The 525 kgf maximum drive force at 0.7 MPa is identical in both directions, while the integrated collet lock yields 5500 N of static holding force. If your load requires less force, step down to the 80 mm bore (2268 N at 0.5 MPa, 3600 N holding force); for heavier loads, step up to the 125 mm bore (5734 N at 0.5 MPa, 8600 N holding force).
Always verify your load does not exceed the 5500 N holding capacity. Engage the lock only after the cylinder stops moving, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the transition. Replacement matches require the 100 mm bore, 80 mm stroke, PT1/2 port, and -S magnet option.
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 5500 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 BSED100X80S FAQ
The integrated rod lock is spring-applied, so it automatically clamps the rod and holds the load in place with a 5500 N static holding force. It requires no live air to maintain the hold, but it is a static lock, not a dynamic brake, so it must only engage after the rod stops.
The drive force is equal both ways: 3681 N at 0.5 MPa and 5153 N at 0.7 MPa, equating to a maximum drive of 525 kgf. The static holding force of the lock is 5500 N. The operating speed range is 30-800 mm/s.
