Airtac BSED Clamping Double Acting Cylinder BSED50X80S
The AirTAC BSED Clamping Double Acting Cylinder BSED50X80S combines a double-rod ISO 15552 cylinder — a Ø20mm rod out BOTH ends for equal force both directions — with an integrated spring-applied, air-released ROD LOCK that holds up to 1400 N in either direction if air is lost. Ø50mm bore, 80mm stroke, PT1/4 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED50X80S
The AirTAC BSED50X80S is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. Because a rod exits both ends, it generates equal drive force in both directions—about 825 N each way at 0.5 MPa—while resisting torsion. The rear rod is ideal for mounting external flags or cam rollers.
A separate G1/8 release port controls the fail-safe collet, delivering a 1400 N static holding force with zero live air. If air pressure drops or an E-stop trips, the mechanism clamps the 20 mm rod instantly. Remember to engage the lock only after the rod stops and release it only when piston sides are pressure-balanced, allowing at least 0.5 seconds.
Double Rod + 1400 N Rod Lock (Ø50mm)
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 BSED50X80S 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 M16×1.5 both ends. Mounting (BSED): Basic, LB, FA, TC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
Theoretical Output Force (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa (max) | 1155 N |
| Max drive (@0.7 MPa) | 118 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 1400 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED50X80S Is Used
Vertical Lift Stations
Lifts 118 kgf loads equally in both directions, engaging the 1400 N collet to prevent drops when air pressure is removed.
Pallet Stops
Halts moving pallets using symmetric double-rod thrust, locking the 20 mm rod instantly to hold position during transfers.
Dual-Tool Machining
Mounts a tool on one end and a cam on the rear rod, utilizing equal 825 N force at 0.5 MPa for precise bidirectional indexing.
Is the Airtac BSED Clamping Double Acting Cylinder BSED50X80S the Right Cylinder?
Select this 50 mm bore when an application requires symmetric thrust up to 1154 N at 0.7 MPa alongside a 1400 N fail-safe hold. If your load demands less force, the 40 mm bore offers 528 N at 0.5 MPa and a 900 N hold; stepping up to the 63 mm bore yields 1402 N at 0.5 MPa and a 2200 N holding capacity. Always verify your load is strictly below the 1400 N static limit, and never use the lock as a dynamic brake. For exact replacements, match the 80 mm stroke, PT1/4 cylinder port, M16x1.5 rod thread, and the -S magnet option for CMSE or DMSE sensors.
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 1400 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 BSED50X80S FAQ
The double-rod design provides equal drive force both ways: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 118 kgf. The integrated fail-safe rod lock provides a separate bidirectional static holding force of 1400 N with no live air.
The spring-applied collet clamps automatically on air loss. To release safely, ensure both piston sides are pressure-balanced and apply air to the dedicated G1/8 release port. Always allow at least 0.5 seconds for the collet to disengage before commanding cylinder motion.
