About the Airtac BSED Clamping Double Acting Cylinder BSED100X700S
The AirTAC BSED100X700S is a double-acting, double-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. Because a rod exits both ends, it delivers equal force in both directions—generating 3681 N each way at 0.5 MPa. The rear rod is ideal for mounting flags or cams while resisting rotational torque.
A separate G1/8 release port controls the fail-safe collet, which clamps the 25 mm rod to provide a 5500 N static holding force with zero live air. If air pressure drops or an E-stop trips, the rod is securely held at position. This mechanism is a static lock, not a dynamic brake; engage it only after the rod stops and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds.
Double Rod + 5500 N Rod Lock (Ø100mm)
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 BSED100X700S 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.

Where the Airtac BSED Clamping Double Acting Cylinder BSED100X700S Is Used
Heavy Vertical Lifts
Lifts heavy platens using 5153 N of equal both-way force, relying on the 5500 N spring-applied rod lock to prevent drops if air pressure is lost.
Machining Station Stops
Halts large workpiece carriages at a precise machining axis. The double-rod design resists rotational torque while the collet holds the 819 kgf load statically.
Pallet Transfer Indexing
Indexes heavy pallets along a conveyor. The rear rod mounts a cam for position feedback while the fail-safe lock holds the pallet securely during loading.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X700S the Right Cylinder?
Select this 100 mm bore when you need both-way symmetric drive (5153 N at 0.7 MPa) combined with fail-safe holding up to 5500 N. If your load requires less force, the 80 mm bore offers 2268 N at 0.5 MPa and a 3600 N hold. For heavier loads, the 125 mm bore provides 5734 N at 0.5 MPa and an 8600 N hold. Always verify your load is under the 5500 N static limit.
With a 700 mm stroke, use an external guide rail to prevent side-loading damage to the seals and rod. To replace this unit, match the 100 mm bore, 700 mm stroke, PT1/2 cylinder port, and -S magnet. Mounting options are limited to Basic, LB, FA, and TC. The -S magnet supports CMSE reed and DMSE electronic sensors for position feedback.
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 5500 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 BSED100X700S FAQ
The integrated rod lock is spring-applied and air-released. If air pressure drops below 0.15 MPa or an E-stop trips, the collet clamps the 25 mm rod, providing a 5500 N static holding force to keep the load in place without live air.
The double-rod design provides equal drive force in both directions: 3681 N at 0.5 MPa and 5153 N at 0.7 MPa (max 525 kgf). This drive force is separate from the 5500 N static holding force of the fail-safe rod lock.
