About the Airtac BSED Clamping Double Acting Cylinder BSED100X400
The AirTAC BSED100X400 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 3681 N each way at 0.5 MPa and 5153 N at 0.7 MPa. The symmetrical annulus area ensures identical thrust and speed in both directions, while the rear rod provides stable mounting for tooling, flags, or anti-rotation cams.
This fail-safe collet mechanism provides a bidirectional static holding force of 5500 N with no live air required. If pressure drops or an E-stop trips, the rod is securely clamped at position. The lock utilizes a separate G1/8 release port, and the system operates at 0.15-0.7 MPa. This SKU is configured without a magnet (-S omitted), meaning 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 BSED100X400 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 |

Where the Airtac BSED Clamping Double Acting Cylinder BSED100X400 Is Used
Vertical Lift Platforms
Hoists raising 500 kg workpieces rely on the 5153 N both-way drive force, while the 5500 N rod lock secures the elevated load instantly if compressed air fails.
Servo Press Indexing
The double-rod design provides equal 3681 N force at 0.5 MPa on advance and retract, with the fail-safe collet holding the press head rigidly against kickback during dwell.
Heavy Pallet Stops
Halts 1000 kg conveyor traffic using symmetric both-way thrust; the spring-applied lock clamps the rod with 5500 N to prevent drift when the line is depressurized for maintenance.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X400 the Right Cylinder?
Select this 100 mm bore when an application requires both-way symmetric thrust up to 5153 N alongside a 5500 N fail-safe hold. If your load demands less force, the 80 mm bore offers 2268 N at 0.5 MPa with a 3600 N holding force. For heavier requirements, the 125 mm bore provides 5734 N at 0.5 MPa and an 8600 N hold. Always verify your static load is at or below the 5500 N holding capacity.
Engage the lock only after the rod completely stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the transition. This is a static holding device, not a dynamic brake; safety-rated controls are required for man-rated or overhead loads. At 400 mm stroke, ensure external guide rails are used to manage side loads and prevent binding. Replacement matches require the exact 100 mm bore, 400 mm stroke, PT1/2 porting, and your chosen mounting (Basic, LB, FA, or TC).
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 BSED100X400 FAQ
The double-rod design provides equal drive force in both directions: 3681 N at 0.5 MPa and 5153 N at 0.7 MPa (max 525 kgf). The integrated spring-applied rod lock provides a separate bidirectional static holding force of 5500 N with no live air.
Upon air loss or E-stop activation, the spring-applied collet clamps the 25 mm rod instantly, holding the load up to 5500 N. To release safely, ensure both cylinder sides are pressure-balanced, apply air to the G1/8 release port, and wait at least 0.5 seconds before commanding motion.
