About the Airtac BSED Clamping Double Acting Cylinder BSED100X80
The AirTAC BSED100X80 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, providing equal force in both directions—delivering 3681 N each way at 0.5 MPa and 5153 N at 0.7 MPa. The symmetrical annulus area ensures consistent push and pull speeds, while the rear rod can mount a flag or cam and resists rotation.
This unit provides a bidirectional fail-safe static holding force of 5500 N with no live air required. If air pressure drops or an E-stop trips, the collet clamps the rod to hold the load in place. The lock is a static holding device, not a dynamic brake; it must be engaged only after the rod stops, and released when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the transition. This SKU ships without a magnet (-S omitted), so it 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 BSED100X80 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.

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 BSED100X80 Is Used
Vertical Lift Platforms
Holds a 5500 N elevated platform securely in place during air loss, while the double-rod design provides 5153 N of equal lifting and lowering force.
Multi-Station Machining
Indexes heavy workpieces with 3681 N of both-way drive force, locking the 25 mm rod instantly when the cycle halts to maintain exact machining positions.
Pallet Diverters
Actuates heavy diverting gates symmetrically in both directions, engaging the fail-safe collet to prevent gate drift if the pneumatic supply drops.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X80 the Right Cylinder?
Select this 100 mm bore cylinder when your application requires both-way symmetric drive force and robust fail-safe holding up to 5500 N. If your load requires less force, the neighboring 80 mm bore provides 2268 N at 0.5 MPa with a 3600 N holding force. If you need greater capacity, the 125 mm bore offers 5734 N at 0.5 MPa and an 8600 N holding force. Always verify your load does not exceed the 5500 N static limit.
Engage the lock only after the rod comes to a complete stop, and release it only when cylinder pressure is balanced across both piston sides. When replacing a unit, match the 100 mm bore, 80 mm stroke, PT1/2 cylinder port, G1/8 release port, and your specific mounting choice (Basic, LB, FA, or TC). For this 80 mm stroke, side-load is minimal, but always ensure the load is guided to prevent binding.
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 BSED100X80 FAQ
The integrated rod lock is spring-applied and air-released. If air pressure is lost, the collet immediately clamps the 25 mm rod, providing a bidirectional static holding force of 5500 N. It is a static lock, not a dynamic brake, and should only engage after the rod stops.
The BSED100X80 delivers a drive force of 3681 N at 0.5 MPa and 5153 N at 0.7 MPa (max 525 kgf), which is equal in both directions due to the double-rod design. The fail-safe rod lock provides a separate static holding force of 5500 N.
