About the Airtac BSED Clamping Double Acting Cylinder BSED32X125
The AirTAC BSED32X125 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 drive force of 345 N each way at 0.5 MPa. The internal collet lock provides a 600 N static holding force to secure the load safely when air is removed.
This unit features a 12 mm rod with an M10x1.25 thread end and a 27 mm adjustable air cushion at both ends. Operating pressure is capped at 0.7 MPa, and the lock is released via a separate G1/8 port. Note that this specific SKU lacks a magnet, so position sensing is not supported.
Double Rod + 600 N Rod Lock (Ø32mm)
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 BSED32X125 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 M10×1.25 both ends. Mounting (BSED): Basic, LB, FA, TC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
Theoretical Output Force (Ø32mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa (max) | 484 N |
| Max drive (@0.7 MPa) | 49 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 600 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED32X125 Is Used
Vertical Lift Jigs
Holds a 125 mm vertical lift jig securely in place with 600 N of fail-safe force, while the double-rod design provides 345 N of equal lifting and lowering force.
Symmetric Transfer Gates
Drives horizontal transfer gates with 345 N of equal both-way force, using the rear rod for cam tracking while the collet lock prevents drift on air loss.
Pick-and-Place Stops
Ideal for small pick-and-place stops where the 12 mm rod provides stable anti-rotation, and the spring-applied lock holds position during E-stops.
Is the Airtac BSED Clamping Double Acting Cylinder BSED32X125 the Right Cylinder?
Select this 32 mm bore model when your application requires symmetric force and fail-safe holding up to 600 N. If your load demands less holding or drive power, the next size down is not available in this series, making 32 mm the minimum baseline. If you need more force, step up to the 40 mm bore, which provides 528 N of drive force at 0.5 MPa and a 900 N holding force. Always confirm your load stays at or below the 600 N static limit.
Engage the lock only after the rod completely stops moving, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the transition. When replacing, match the 32 mm bore, 125 mm stroke, PT1/8 cylinder port, and the chosen mounting style (Basic, LB, FA, or TC).
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 600 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 BSED32X125 FAQ
If air is lost, the spring-applied collet engages and provides a 600 N static holding force to keep the rod at its position. It is a fail-safe hold, not a dynamic brake, so it must only be engaged after the rod stops moving.
The double-rod design provides equal drive force in both directions: 345 N at 0.5 MPa and 483 N at 0.7 MPa (max 49 kgf). The integrated fail-safe rod lock separately provides a 600 N static holding force with no live air required.
