About the Airtac BSED Clamping Double Acting Cylinder BSED80X50S
The AirTAC BSED80X50S 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 collet lock provides a 3600 N static holding force, keeping the load fixed if air pressure drops.
This 80 mm bore unit uses a PT3/8 cylinder port and a separate G1/8 release port. The -S magnet supports CMSE reed and DMSE electronic sensors. The extruded aluminum ISO 15552 body has no external tie rods, and the lock engages only after the rod stops, requiring 0.5 s to release once piston sides are balanced.
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 BSED80X50S 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 BSED80X50S Is Used
Servo-Driven Press Clamping
Uses the 3175 N equal both-way drive to clamp parts, then engages the 3600 N rod lock to hold position securely during secondary machining without continuous air.
Pallet Lift-and-Hold Stations
Lifts heavy pallets using symmetric double-rod force, relying on the spring-applied collet to prevent drops during air loss at 0.7 MPa operating ceiling.
Bi-Directional Indexing Gates
Moves heavy indexing gates equally in both directions while the rear rod carries a flag; the fail-safe lock freezes the gate exactly at 50 mm stroke.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X50S the Right Cylinder?
Choose this 80 mm bore model when a task needs symmetric both-way force and a 3600 N fail-safe hold. If your load is lighter, the 63 mm bore offers 1402 N at 0.5 MPa and a 2200 N hold; for heavier demands, the 100 mm bore provides 3681 N at 0.5 MPa and a 5500 N hold. Ensure the load stays under 3600 N.
The 50 mm stroke is compact, but always verify guide alignment to prevent side-load wear. For replacements, match the 80 mm bore, 50 mm stroke, PT3/8 port, and -S magnet. Remember, the lock is a static hold, not a dynamic brake; engage it only after motion stops.
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 BSED80X50S FAQ
The double-rod drive force is equal both ways: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa (max 324 kgf). The integrated spring-applied rod lock provides a separate 3600 N static holding force.
The collet lock is spring-applied, so it clamps the rod automatically if air is lost, holding up to 3600 N. To release safely, pressure-balance both piston sides, apply air to the G1/8 release port, and allow at least 0.5 s before moving.
