Airtac BSED Clamping Double Acting Cylinder BSED100X50
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X50 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, 50mm stroke, PT1/2 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED100X50
The AirTAC BSED100X50 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—about 3681 N each way at 0.5 MPa. The rear rod provides a stable platform for mounting flags or tooling while actively resisting rotation.
This fail-safe collet lock clamps the rod bidirectionally with a static holding force of 5500 N whenever air pressure is lost. It is a holding device, not a dynamic brake; engage it only after the rod stops and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. This unit has no 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 BSED100X50 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 BSED100X50 Is Used
Heavy Fixture Locking
Holds a 525 kgf machining fixture securely at the 50 mm mark using the 5500 N fail-safe collet, while the 5153 N both-way drive shifts the heavy payload between stations.
Pallet Stop Arm
The double-rod design resists torsional stress as a 100 mm stop arm cycles, with the spring-applied lock engaging to hold the 5500 N load safely during an E-stop.
Symmetric Transfer Gate
Drives a dual-action gating mechanism with equal 3681 N force in both directions at 0.5 MPa, ensuring consistent speed regardless of travel direction.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X50 the Right Cylinder?
Select this 100 mm bore when your application requires symmetric drive force and reliable mid-stroke positioning. Verify your load does not exceed the 5500 N static holding force. If you need less force, the 80 mm bore provides 2268 N drive force at 0.5 MPa and 3600 N holding force. If you need more, the 125 mm bore offers 5734 N drive force at 0.5 MPa and 8600 N holding force.
Operating pressure is capped at 0.7 MPa with a PT1/2 cylinder port and a separate G1/8 lock-release port. When replacing, match the 50 mm stroke, PT thread, and mounting choice (Basic, LB, FA, or TC). Because this SKU lacks a magnet, you must add the -S option if your control system requires position feedback.
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 BSED100X50 FAQ
The integrated spring-applied collet immediately clamps the rod, providing a 5500 N static holding force to keep the load in place. It is a fail-safe lock, not a dynamic brake, so it must only be engaged after the rod has stopped moving.
The drive force is equal both ways: 3681 N at 0.5 MPa and 5153 N at 0.7 MPa, with a maximum drive of 525 kgf. The static holding force of the rod lock is 5500 N. Operating pressure is 0.15-0.7 MPa.
