About the Airtac BSED Clamping Double Acting Cylinder BSED100X250S
The AirTAC BSED100X250S is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A Ø25 mm 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 rear rod can mount a flag or cam while resisting rotation.
The fail-safe collet lock provides a 5500 N static holding force without consuming live air. A separate G1/8 release port controls the lock, which must only engage after the rod stops moving and release when piston sides are pressure-balanced (allow at least 0.5 s). This model includes a magnetic piston (-S) for CMSE or DMSE sensors and adjustable air cushions at both ends.
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 BSED100X250S 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 BSED100X250S Is Used
Vertical Lift Gates
Holds elevated 4500 kg-equivalent gates mid-air using the 5500 N static lock, while the 5153 N both-way drive raises and lowers the load with equal speed.
Dual-End Machining Jigs
Uses the twin rods to present a workpiece on one end and a cam flag on the other, maintaining 3681 N of symmetric clamping force at 0.5 MPa.
Heavy Pallet Stops
Deploys a stopper blade via the front rod while the rear rod tracks position, engaging the 5500 N fail-safe lock to hold pallets during E-stops.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X250S the Right Cylinder?
Select this 100 mm bore when an application requires both-way symmetric thrust up to 525 kgf and 5500 N of static drop-prevention. If your load is lighter, the 80 mm bore offers 2268 N drive force at 0.5 MPa and a 3600 N hold. For heavier loads, the 125 mm bore provides 5734 N at 0.5 MPa and an 8600 N hold. Always verify the actual load stays under the 5500 N holding threshold.
Engage the lock only after the rod completely stops; release it only after balancing pressure on both piston sides. This cylinder uses a PT1/2 cylinder port, a G1/8 release port, and a 250 mm stroke. For this stroke length, ensure external guide rails are used to absorb side loads and prevent rod binding. Replacement units must match the 100 mm bore, 250 mm stroke, PT thread, and -S magnet options.
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 BSED100X250S FAQ
The integrated spring-applied collet immediately clamps the rod, providing a 5500 N static holding force to keep the load in place without live air. It is a fail-safe static lock, not a dynamic brake, so it must engage only after the rod stops moving.
The double-rod design delivers equal force both ways: 3681 N at 0.5 MPa and 5153 N at 0.7 MPa, with a maximum drive of 525 kgf. The static fail-safe holding force of the lock is 5500 N.
