Airtac BSED Clamping Double Acting Cylinder BSED100X75
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X75 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 5500 N in either direction if air is lost. Ø100mm bore, 75mm stroke, PT1/2 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED100X75
The AirTAC BSED100X75 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, yielding equal force in both directions—about 3681 N each way at 0.5 MPa. The rear rod is ideal for mounting external flags or cams while resisting rotational torque.
This unit provides a bidirectional static holding force of 5500 N with no live air required. If air pressure drops or an E-stop trips, the collet clamps the 25 mm rod to freeze the load in place. Note that this lock is a static holding device, not a dynamic brake; it must engage only after the rod stops moving.
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 BSED100X75 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 (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa (max) | 5154 N |
| Max drive (@0.7 MPa) | 526 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 5500 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED100X75 Is Used
Heavy Machining Fixtures
Clamps large castings using 5153 N of equal both-way drive force, while the 5500 N rod lock holds the heavy workpiece securely in place during cutting operations without consuming live air.
Overhead Z-Axis Lifts
Raises and lowers 500 kg payloads with symmetric force, relying on the fail-safe collet to prevent gravity-driven drops if the 0.7 MPa air supply is lost mid-cycle.
Pallet Stop Gates
Uses the dual-rod design to resist side-load twisting on the stop blade, engaging the 5500 N static hold to lock the gate rigid against moving pallet impacts.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X75 the Right Cylinder?
Select this 100 mm bore when an application requires both-way symmetric drive force up to 5153 N at 0.7 MPa alongside a robust 5500 N fail-safe hold. If your load demands less force, the 80 mm bore offers 2268 N drive force at 0.5 MPa and a 3600 N hold. For heavier loads, the 125 mm bore provides 5734 N drive force at 0.5 MPa and an 8600 N hold. Always verify your load stays under the 5500 N holding threshold.
This SKU lacks the -S magnet option, so it cannot support CMSE or DMSE position sensors. To replace safely, match the 75 mm stroke, PT1/2 cylinder port, and mounting choice (Basic, LB, FA, or TC). Engage the lock only after the rod stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds for the collet to clear.
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 BSED100X75 FAQ
The double-rod design provides equal drive force in both directions: 3681 N at 0.5 MPa and 5153 N at 0.7 MPa, with a maximum drive equivalent of 525 kgf. Separately, the integrated spring-applied rod lock provides a bidirectional static holding force of 5500 N.
Upon air loss or E-stop activation, the spring-applied collet instantly clamps the rod, engaging the 5500 N static hold. To release safely, apply pressure to the separate G1/8 release port only after both cylinder piston sides are pressure-balanced, allowing at least 0.5 seconds for the collet to disengage before motion.
