About the Airtac BSED Clamping Double Acting Cylinder BSED100X900
The AirTAC BSED100X900 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 and speed in both directions—specifically 3681 N each way at 0.5 MPa. The fail-safe collet mechanism provides a 5500 N static holding force, clamping the rod bidirectionally with zero live air required.
Built on an extruded aluminum barrel without external tie rods, this unit features a 25 mm rod, M20x1.5 rod-end thread, and a 36 mm cushion length on both ends. The lock utilizes a separate G1/8 release port and engages only after the piston stops, requiring 0.5 s to release once pressure-balanced. This non-magnet variant omits the -S option, so CMSE or DMSE position sensors are not supported on this SKU.
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 BSED100X900 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 BSED100X900 Is Used
Heavy Vertical Lifts
Holds a 500 kg vertical axis securely mid-stroke with 5500 N of fail-safe force during an E-stop, while the 5153 N both-way drive thrust raises and lowers the load equally.
Dual-Side Machining Jigs
Uses the rear rod for a cam flag to confirm position, providing equal 3681 N clamping force at 0.5 MPa in both directions for symmetrical part machining.
Pallet Stop Gates
Deploys a 900 mm stroke to halt heavy pallets, engaging the 5500 N spring-applied collet lock to prevent any bounce-back once the assembly line halts.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X900 the Right Cylinder?
Select this 100 mm bore when an application demands symmetric thrust up to 5153 N at 0.7 MPa alongside a robust 5500 N fail-safe hold. If your load requires less force, step down to the 80 mm bore (2268 N at 0.5 MPa drive, 3600 N holding force). If you need greater drive and holding capacity, step up to the 125 mm bore (5734 N at 0.5 MPa drive, 8600 N holding force). Always verify the static load does not exceed the 5500 N lock rating.
At 900 mm stroke, mounting long loads on the extended rod can induce severe side loads; use external linear guides to prevent binding and premature seal wear. The operating pressure is capped at 0.7 MPa, and the lock-release port is G1/8. When replacing, match the 100 mm bore, 900 mm stroke, PT1/2 cylinder port, and Basic/LB/FA/TC mounting choice.
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 BSED100X900 FAQ
The spring-applied collet immediately clamps the rod, providing a 5500 N static holding force with no live air. It is a fail-safe lock, not a dynamic brake, so it must engage only after the rod stops. For overhead or man-rated loads, always use separate safety-rated controls.
The drive force is equal both ways: 3681 N at 0.5 MPa and 5153 N at 0.7 MPa (max 525 kgf). The static holding force of the lock is 5500 N. The double-rod operates at 30-800 mm/s, capped at a 0.7 MPa operating pressure.
