Airtac BSED Clamping Double Acting Cylinder BSED100X225S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X225S 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, 225mm stroke, PT1/2 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED100X225S
The AirTAC BSED100X225S 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, while the fail-safe collet mechanism delivers a 5500 N static holding force with no live air required.
This 100 mm bore unit utilizes a PT1/2 cylinder port alongside a dedicated G1/8 lock-release port. The extruded aluminum body incorporates adjustable air cushions at both ends, and the included -S magnet enables precise position sensing with CMSE reed or DMSE electronic 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 BSED100X225S 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 BSED100X225S Is Used
Vertical Lift Station
Holds a 5153 N vertical load safely mid-stroke with its 5500 N fail-safe collet during an E-stop, while the double-rod design ensures stable lifting without rotation.
Heavy-Duty Indexing
Provides equal 3681 N both-way drive at 0.5 MPa for shifting heavy pallets, engaging the lock to hold the 100 mm bore cylinder rigidly during workstation processing.
Multi-Tool Machining
Uses the rear rod extension to mount a secondary cam or flag for DMSE electronic sensor triggering, maintaining precise symmetric force for tool actuation.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X225S the Right Cylinder?
Select this 100 mm bore model when your application requires both-way symmetric thrust up to 5153 N at 0.7 MPa and a robust 5500 N static hold. If your load demands less force, the 80 mm bore offers 2268 N drive at 0.5 MPa with a 3600 N hold; stepping up is not possible as 100 mm is the second largest, but the 125 mm bore provides 5734 N drive at 0.5 MPa and 8600 N holding force for heavier needs.
Always verify your load does not exceed the 5500 N holding capacity. 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 s for the transition. For drop-in replacements, match the 225 mm stroke, PT1/2 port, M20x1.5 rod thread, and your specific mounting choice from 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 BSED100X225S FAQ
This cylinder delivers an equal both-way drive force of 3681 N at 0.5 MPa and 5153 N at 0.7 MPa, with a maximum drive of 525 kgf. The integrated fail-safe rod lock provides a static holding force of 5500 N.
The spring-applied, air-released collet engages automatically when air pressure is lost or removed, clamping the 25 mm rod for a bidirectional 5500 N static hold. It is not a dynamic brake, so it must only be engaged after the rod stops moving.
