Airtac BSED Clamping Double Acting Cylinder BSED100X75S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X75S 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 BSED100X75S
The AirTAC BSED100X75S 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 force in both directions—about 3681 N each way at 0.5 MPa and 5153 N at 0.7 MPa. The rear rod provides excellent anti-rotation stability and can mount tooling or position flags.
This unit provides a bidirectional fail-safe static holding force of 5500 N with no live air required. The lock engages via a collet mechanism when air is lost or E-stop is tripped. It features a separate G1/8 release port, adjustable air cushions at both ends, and a magnetic piston (-S) compatible with CMSE reed and DMSE electronic sensors.
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 BSED100X75S 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 BSED100X75S Is Used
Overhead Lift Stations
Holds a 5500 N vertical load securely during air loss, while the double-rod design moves 5153 N both up and down for balanced lifting.
Multi-Station Machining
The rear rod carries index flags for CMSE sensors, and the collet lock clamps the 25 mm rod to prevent drift during heavy 525 kgf machining cycles.
Pallet Stop Gates
Provides equal push and pull force to retract and extend stops, engaging its fail-safe brake to hold position if the air supply drops.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X75S the Right Cylinder?
Select this 100 mm bore model when an application demands both symmetric drive force and reliable position holding. Verify your load does not exceed the 5500 N static holding capacity. If you need less force, the 80 mm bore offers 2268 N at 0.5 MPa and 3600 N holding force. If you need more, the 125 mm bore provides 5734 N at 0.5 MPa and 8600 N holding force.
Remember the safety rule: engage the lock only after the rod stops moving, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. For exact replacements, match the 75 mm stroke, PT1/2 port, and mounting style (Basic, LB, FA, or TC).
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 BSED100X75S FAQ
The spring-applied collet immediately clamps the rod, providing a bidirectional static holding force of 5500 N with no live air. It is a fail-safe hold, not a dynamic brake, so it only engages after the rod stops moving.
The double-rod design delivers equal force both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a max drive of 525 kgf. To release the 5500 N lock safely, pressure-balance both piston sides and apply air to the G1/8 release port, allowing at least 0.5 seconds.
