Airtac BSED Clamping Double Acting Cylinder BSED100X300
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X300 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, 300mm stroke, PT1/2 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED100X300
The AirTAC BSED100X300 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—yielding 3681 N each way at 0.5 MPa and 5153 N at 0.7 MPa. The ISO 15552 extruded aluminum barrel provides standard dimensional interchangeability without external tie rods.
This fail-safe collet mechanism provides a bidirectional static holding force of 5500 N with no live air required. A separate G1/8 release port controls the lock independently of the PT1/2 cylinder ports. Because this SKU lacks a magnet (-S), 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 BSED100X300 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 BSED100X300 Is Used
Heavy Lift Station Drop Prevention
Secures vertical machining center doors weighing up to 5500 N during power loss. The 5153 N both-way drive ensures smooth, equal-force up and down transitions.
Pallet Transfer Arrestor
Halts a 300mm stroke pallet transfer at the exact end position. The double-rod design mounts a rear flag cam, while the lock holds the 5153 N load without live air.
Overhead Hoist Positioning
Maintains a lifted tooling head securely at height. The spring-applied collet engages instantly on E-stop, providing a 5500 N static hold against gravity.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X300 the Right Cylinder?
Select this 100mm bore when an application demands both-way drive force up to 5153 N alongside a 5500 N fail-safe hold. If your load requires less force, the adjacent 80mm bore offers 2268 N at 0.5 MPa with a 3600 N hold. For heavier requirements, the 125mm bore provides 5734 N at 0.5 MPa and an 8600 N hold. Always ensure the static load is at or below 5500 N.
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. For this 300mm stroke, incorporate an external guide to prevent side-loading and protect the rod seal. When replacing, match the 100mm bore, 300mm stroke, PT1/2 port, and mounting style (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 BSED100X300 FAQ
The integrated spring-applied collet immediately clamps the rod, providing a bidirectional static holding force of 5500 N without any live air. The lock is a holding device, not a dynamic brake, so it must engage only after the rod stops.
The double-rod design provides equal drive force 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. Operating speed is 30-800 mm/s, capped at a 0.7 MPa pressure ceiling.
