About the Airtac BSED Clamping Double Acting Cylinder BSED80X175S
The AirTAC BSED80X175S is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, providing equal force and speed in both directions—delivering 2268 N each way at 0.5 MPa and 3175 N at 0.7 MPa. The rear rod is ideal for mounting flags, cams, or tooling while resisting rotation.
This fail-safe collet lock provides a bidirectional static holding force of 3600 N without requiring live air. If air pressure drops or an E-stop trips, the rod is securely clamped at position. It engages only after the rod stops and releases via a dedicated G1/8 port once piston sides are pressure-balanced. The -S magnet enables position sensing with CMSE reed or DMSE electronic switches.
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 BSED80X175S 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 BSED80X175S Is Used
Vertical Lift Gates
Holds elevated gates securely in place with 3600 N of static force during air loss, while the double-rod design drives 3175 N consistently in both up and down directions.
Pallet Stopper Arms
Provides hard stopping for heavy pallets using equal both-way force, with the fail-safe collet preventing any drift when the conveyor line is depressurized for maintenance.
Dual-Tool Machining Jigs
Mounts a work clamp on the front rod and a sensor flag on the rear rod, utilizing anti-rotation properties and 2268 N of symmetric force for precise machining cycles.
Is the Airtac BSED Clamping Double Acting Cylinder BSED80X175S the Right Cylinder?
Select this 80 mm bore when an application requires both-way symmetric drive (324 kgf max at 0.7 MPa) combined with fail-safe holding up to 3600 N. If your load requires less force, the 63 mm bore offers 1402 N drive and 2200 N holding; for heavier loads, the 100 mm bore provides 3681 N drive and 5500 N holding. Always verify your load is under 3600 N, and allow at least 0.5 seconds for the lock to engage or release after pressure balancing. When replacing a unit, match the 175 mm stroke, PT3/8 cylinder port, M20x1.5 rod thread, and mounting style (Basic, LB, FA, or TC).
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 BSED80X175S FAQ
The integrated spring-applied collet instantly clamps the rod, providing a 3600 N bidirectional static holding force to keep the load in position. It is a fail-safe hold, not a dynamic brake, so it must only be engaged after the rod has completely stopped moving.
The double-rod design delivers equal drive force in both directions: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a maximum drive force of 324 kgf. This drive force is separate from the 3600 N static holding force of the rod lock.
