About the Airtac BSED Clamping Double Acting Cylinder BSED80X500S
The AirTAC BSED80X500S 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 2268 N each way at 0.5 MPa and 3175 N at 0.7 MPa. The fail-safe collet lock provides a 3600 N static holding force, clamping the rod securely during air loss or E-stop events.
This 80mm bore unit includes a 500mm stroke and an -S magnet for CMSE reed or DMSE electronic sensors. It features a PT3/8 cylinder port, a separate G1/8 lock-release port, and adjustable air cushions at both ends. The lock engages only after the rod stops and releases when piston sides are pressure-balanced, requiring a minimum 0.5-second cycle.
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 BSED80X500S 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 BSED80X500S Is Used
Vertical Lift Platforms
Holds a 360kg vertical load mid-stroke with zero live air, while the 3175N equal both-way drive raises and lowers the platform smoothly.
Pallet Indexing Stops
Provides a rear-rod flag for position confirmation and uses the spring-applied collet to lock the 500mm stroke securely during E-stops.
Multi-Tool Machining
Equal push and pull force of 2268N at 0.5 MPa allows mounting tooling on either rod end, with the lock holding position during part changes.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X500S the Right Cylinder?
Select the BSED80X500S when an application demands both symmetric actuation and fail-safe holding. Verify your load to hold is 3600 N or less. If you need less force, the 63mm bore delivers 1402 N at 0.5 MPa with a 2200 N hold; if stepping up, the 100mm bore provides 3681 N at 0.5 MPa and a 5500 N hold. Operating pressure is capped at 0.7 MPa. At 500mm stroke, use external guide rails to prevent side loads from damaging the rod seals. For a direct replacement, match the 80mm bore, 500mm stroke, PT3/8 thread, and -S magnet.
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 BSED80X500S FAQ
The equal both-way drive force is 2268 N at 0.5 MPa and 3175 N at 0.7 MPa (max 324 kgf). The static fail-safe holding force of the integrated rod lock is 3600 N, which holds the load with no live air.
The lock is a spring-applied, air-released collet, not a dynamic brake. Engage it only after the rod stops. To release, ensure both piston sides are pressure-balanced via the G1/8 release port, and allow at least 0.5 seconds for the transition.
