Airtac BSED Clamping Double Acting Cylinder BSED100X350
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X350 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, 350mm stroke, PT1/2 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED100X350
The AirTAC BSED100X350 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 drive force of 3681 N each way at 0.5 MPa and 5153 N at 0.7 MPa. The rear rod is ideal for mounting flags or tooling while resisting rotational torque.
This unit delivers a bidirectional static holding force of 5500 N with no live air required. The collet lock engages safely only after the rod stops, requiring pressure balance on both piston sides and at least 0.5 s to release. It features a 25 mm rod, M20x1.5 thread, PT1/2 cylinder ports, and a dedicated G1/8 release port.
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 BSED100X350 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 BSED100X350 Is Used
Overhead Lift Stations
Holds a 5500 N vertical lift securely in place during air loss or E-stop, while the double-rod delivers 5153 N of equal lifting and lowering force.
Multi-Station Machining
Uses the rear rod for a cam flag to index stops, providing 3681 N of both-way clamping force at 0.5 MPa with fail-safe collet engagement.
Heavy Pallet Stops
Arrests heavy pallet movement with a 5500 N static lock, utilizing the symmetric double-rod to retract the stop at high cycle speeds.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X350 the Right Cylinder?
Choose this 100 mm bore when an application demands symmetric both-way force and fail-safe positioning. Verify your load is under the 5500 N holding capacity. If you need less force, the 80 mm bore offers 2268 N at 0.5 MPa and 3600 N holding; if you need more, the 125 mm bore provides 5734 N at 0.5 MPa and 8600 N holding.
Operating pressure is capped at 0.7 MPa. Because this 350 mm stroke is over 300 mm, add external guide rails to prevent side-loading damage. This SKU has no -S magnet, so position sensing via CMSE or DMSE sensors is not supported. To replace, match the 100 mm bore, 350 mm stroke, PT port, and Basic/LB/FA/TC mounting.
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 BSED100X350 FAQ
The spring-applied collet instantly clamps the rod, providing a bidirectional static holding force of 5500 N without any live air. It is a fail-safe holding lock, not a dynamic brake, so it must only engage after the rod has completely stopped.
The double-rod drive force is equal both ways: 3681 N at 0.5 MPa and 5153 N at 0.7 MPa, with a max drive of 525 kgf. The separate static holding force for the integrated rod lock is 5500 N.
