Airtac BSED Clamping Double Acting Cylinder BSED80X75S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED80X75S combines a double-rod ISO 15552 cylinder — a Ø25mm rod out BOTH ends for equal force both directions — with an integrated spring-applied, air-released ROD LOCK that holds up to 3600 N in either direction if air is lost. Ø80mm bore, 75mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED80X75S
The AirTAC BSED80X75S is a double-acting, double-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A rod exits both ends, delivering equal force in both directions—2268 N each way at 0.5 MPa and 3175 N at 0.7 MPa. The rear rod provides excellent anti-rotation stability and can carry tooling or position flags.
The fail-safe collet lock provides a bidirectional static holding force of 3600 N with no live air required. A separate G1/8 release port controls the lock, which must only engage after the rod stops and release when both piston sides are pressure-balanced (allow at least 0.5 s). The extruded aluminum barrel has no external tie rods, and the -S magnet supports CMSE reed and 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 BSED80X75S 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 BSED80X75S Is Used
Overhead Lift Stops
Holds vertical lifting jigs safely mid-stroke with 3600 N of static hold if air pressure drops, while the double-rod design delivers 3175 N of equal lift and lower force.
Machining Clamps
Secures machining fixtures in place during cycle interruptions using the fail-safe collet, with equal 2268 N force at 0.5 MPa for precise bidirectional clamping.
Pallet Indexing
Indexes conveyor pallets from both ends using the twin rods, engaging the 3600 N lock only after the belt fully stops to prevent dynamic braking damage.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X75S the Right Cylinder?
Choose this 80 mm bore when you need symmetric both-way force (3175 N at 0.7 MPa) combined with a 3600 N fail-safe hold. If your load drops below 1400 N holding requirement, step down to the 50 mm bore (825 N drive at 0.5 MPa, 1400 N hold). If you need more force, step up to the 100 mm bore (3681 N drive at 0.5 MPa, 5500 N hold). Operating pressure is capped at 0.7 MPa. When replacing, match the 80 mm bore, 75 mm stroke, PT3/8 cylinder port, and -S magnet. For any stroke over 300 mm, add external guide rails to prevent side-load wear.
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 BSED80X75S FAQ
The spring-applied collet instantly clamps the rod, providing a 3600 N bidirectional static holding force with no live air. It is a fail-safe hold, not a dynamic brake, so it must engage only after the rod stops. For overhead or man-rated loads, always use separate safety-rated controls.
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 holding force is 3600 N. To release safely, pressure-balance both piston sides and apply air to the G1/8 release port, allowing at least 0.5 seconds before moving.
