About the Airtac BSED Clamping Double Acting Cylinder BSED80X200S
The AirTAC BSED80X200S 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 force in both directions—delivering 2268 N each way at 0.5 MPa and 3175 N at 0.7 MPa. The rear rod extension is ideal for mounting external flags or cams while resisting rotational torque.
This fail-safe collet mechanism provides a 3600 N static holding force with no live air required. If pressure drops or an E-stop trips, the rod is securely clamped at position. Control relies on a dedicated G1/8 release port, and the -S magnet option enables position tracking with CMSE reed or DMSE electronic sensors.
Double Rod + 3600 N Rod Lock (Ø80mm)
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 BSED80X200S 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.

Theoretical Output Force (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa (max) | 3175 N |
| Max drive (@0.7 MPa) | 324 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 3600 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED80X200S Is Used
Overhead Lift Stations
Holds a 3600 N vertical load safely in place during an air loss event, while the 3175 N equal both-way drive force precisely raises and lowers the work platform without drift.
Multi-Station Machining
Uses the rear exiting rod to mount a cam for sequencing, providing symmetric 2268 N force at 0.5 MPa to shuttle heavy fixtures between stations with secure mid-cycle clamping.
Pallet Accumulation
Stops and holds heavy pallets securely with a 3600 N fail-safe grip when air is removed, using the double-rod design to maintain consistent speed and force while indexing goods.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X200S the Right Cylinder?
Select this 80 mm bore when an application demands symmetric 3175 N drive force alongside a 3600 N static hold. If your load requires less force, the 63 mm bore offers 1402 N at 0.5 MPa with a 2200 N hold; for heavier loads, stepping up to the 100 mm bore yields 3681 N at 0.5 MPa and a 5500 N hold. Always verify your load is under the 3600 N holding limit.
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. When replacing a unit, match the 200 mm stroke, PT3/8 cylinder port, M20x1.5 rod thread, and mounting style (Basic, LB, FA, or TC). For this 200 mm stroke, ensure adequate guide support to prevent excessive side loading on the seals.
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 3600 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 BSED80X200S FAQ
The integrated spring-applied collet immediately engages to provide a 3600 N static holding force, securing the load in place without live air. It is a fail-safe lock, not a dynamic brake, so it must only be engaged after the rod stops moving.
The double-rod design provides equal force both ways: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a maximum drive force of 324 kgf. Separately, the fail-safe rod lock provides a 3600 N static holding force. Release the lock via the G1/8 port only when both piston sides are pressure-balanced.
