About the Airtac BSED Clamping Double Acting Cylinder BSED80X500
The AirTAC BSED80X500 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 2268 N each way at 0.5 MPa (3175 N at 0.7 MPa). The bidirectional fail-safe collet lock delivers a 3600 N static holding force with no live air required.
This 80mm bore unit uses a PT3/8 cylinder port and a separate G1/8 lock-release port. It features adjustable air cushions at both ends (36mm length) and operates at 30-800 mm/s. This specific SKU has no magnet (-S), meaning it is not compatible with CMSE or DMSE position 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 BSED80X500 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 (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 BSED80X500 Is Used
Overhead Z-Axis Lifts
Holds a vertical load securely with 3600 N of fail-safe force during an E-stop or air loss, while the double-rod design provides equal 3175 N lifting and lowering force at 0.7 MPa.
Large Press Ejection
Uses the rear rod for a cam or flag trigger while the front rod ejects heavy parts, relying on the 2268 N both-way drive force and the lock to hold position during part transfer.
Heavy Pallet Stops
Halts 500mm-stroke pallet movement using the symmetric double-rod output, engaging the 3600 N spring-applied collet lock to freeze the load without consuming continuous air.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X500 the Right Cylinder?
Select this model when your application requires symmetric push/pull force and a fail-safe hold up to 3600 N. If your load demands less force, the 63mm bore provides 1402 N at 0.5 MPa with a 2200 N holding force. For higher loads, step up to the 100mm bore, offering 3681 N at 0.5 MPa and a 5500 N hold.
Because the 500mm stroke is long, ensure adequate side-load support and use a guide rail to prevent rod binding. To release the lock safely, pressure-balance both piston sides first, then apply air to the G1/8 release port, allowing at least 0.5 seconds before moving. This unit uses the standard PT3/8 port, M20x1.5 rod thread, and Basic/LB/FA/TC mounting.
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 BSED80X500 FAQ
The spring-applied collet immediately clamps the rod, providing a 3600 N static holding force to prevent movement. It is a fail-safe lock, not a dynamic brake, so it must only engage after the rod has completely stopped. The full force set is 2268 N @0.5 MPa, 3175 N @0.7 MPa, max 324 kgf drive, and 3600 N holding force.
You must first pressure-balance both sides of the piston to prevent uncontrolled movement. Then, apply 0.15-0.7 MPa air to the separate G1/8 release port to overcome the spring and unclamp the collet. Always allow at least 0.5 seconds for the mechanism to fully release before commanding motion.
