Airtac BSED Clamping Double Acting Cylinder BSED80X800S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED80X800S 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, 800mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED80X800S
The AirTAC BSED80X800S 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. The collet lock delivers a 3600 N static holding force with no live air required.
This fail-safe lock engages bidirectionally whenever air is lost or an E-stop trips, securely clamping the Ø25 mm rod. It features a separate G1/8 release port and a 36 mm adjustable air cushion at both ends. The -S magnet option supports CMSE reed and DMSE electronic sensors for end-of-stroke detection.
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 BSED80X800S 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 BSED80X800S Is Used
Overhead Z-Axis Safety
Holds a 3600 N vertical load instantly on air loss, preventing crashes while the 3175 N both-way force handles precise up/down positioning.
Pallet Stop Gate
Uses the rear rod for a cam flag to confirm gate position, while the fail-safe lock resists 3600 N of pallet impact force when engaged.
Multi-Tool Machining
Equal 2268 N force in both directions indexes a tooling carriage, with the collet lock providing vibration-free clamping during machining.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X800S the Right Cylinder?
Select this 80 mm bore model when your application demands symmetric push/pull force alongside a 3600 N fail-safe hold. If your load is under 1400 N, step down to the 50 mm bore (825 N @0.5 MPa, 1400 N hold); if you need more drive power, step up to the 100 mm bore (3681 N @0.5 MPa, 5500 N hold). Never use the lock as a dynamic brake; engage it only after the rod stops, and release it only when both piston sides are pressure-balanced (allow >=0.5 s). For an 800 mm stroke, use a linear guide to prevent side-load damage. Replacement match: 80 mm bore, 800 mm stroke, PT3/8 port, magnet included.
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 BSED80X800S FAQ
If air is lost, the spring-applied collet instantly clamps the rod, providing a 3600 N bidirectional static hold with no live air. It is a holding lock, not a dynamic brake, so engage it only after the rod stops.
The double-rod design provides equal drive force both ways: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa (max 324 kgf). The fail-safe rod lock provides a separate 3600 N static holding force.
