Airtac BSED Clamping Double Acting Cylinder BSED100X700
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X700 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, 700mm stroke, PT1/2 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED100X700
The AirTAC BSED100X700 is a double-acting, double-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A rod exits both ends, delivering equal force in both directions at 3681 N each way at 0.5 MPa and 5153 N at 0.7 MPa. The rear rod is ideal for mounting flags or cams and resists rotation.
The fail-safe collet lock provides a 5500 N bidirectional static holding force with no live air required. The lock engages when air is lost or an E-stop is tripped, holding the rod securely at position. It operates via a separate G1/8 release port, and the cylinder uses a PT1/2 port. This unit has no magnet (-S) and does not support CMSE or DMSE position sensors.
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 BSED100X700 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 BSED100X700 Is Used
Heavy Vertical Lifts
Holds a 5500 N vertical load safely in place during air loss, while the 5153 N both-way drive force raises and lowers the mass.
Machining Fixtures
Clamps heavy workpieces from both ends using equal push and pull force, locking the 700 mm stroke securely during cutting cycles.
Pallet Stops
Uses the rear rod for cam actuation while the main rod stops heavy pallets, engaging the 5500 N lock to prevent creep.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X700 the Right Cylinder?
Select this 100 mm bore cylinder when your application requires symmetric both-way drive and a fail-safe hold up to 5500 N. If your load exceeds 5500 N, step up to the 125 mm bore (8028 N drive at 0.7 MPa, 8600 N holding force). If your load is lighter, step down to the 80 mm bore (3175 N drive at 0.7 MPa, 3600 N holding force).
Always 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 700 mm stroke, use external guide rails to manage side loads and prevent binding. Replacement parts must match the 100 mm bore, 700 mm stroke, PT1/2 port, and basic mounting interface.
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 BSED100X700 FAQ
The integrated spring-applied collet lock engages automatically, providing a 5500 N static holding force to keep the rod at its position. It is a fail-safe hold, not a dynamic brake, so it must only engage after the rod stops.
The double-rod drive force is equal both ways: 3681 N at 0.5 MPa and 5153 N at 0.7 MPa (max 525 kgf). To release the 5500 N lock, apply pressure to the separate G1/8 release port only after both piston sides are pressure-balanced, allowing at least 0.5 s.
