Airtac BSED Clamping Double Acting Cylinder BSED100X500S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X500S 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, 500mm stroke, PT1/2 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED100X500S
The AirTAC BSED100X500S is a double-acting, double-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A rod exits both ends, delivering equal force in both directions at 3681 N each way at 0.5 MPa. The fail-safe collet lock provides a 5500 N static holding force with no live air required.
This 100 mm bore unit features a Ø25 mm rod with an M20x1.5 thread, a PT1/2 cylinder port, and a dedicated G1/8 lock-release port. The extruded aluminum barrel has no external tie rods, and the -S magnet supports CMSE reed and DMSE electronic sensors for position feedback.
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 BSED100X500S 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 BSED100X500S Is Used
Heavy Machining Jigs
Clamps large cast iron fixtures with 5153 N of equal both-way force, then engages the 5500 N spring collet lock to hold the workpiece rigidly during cutting without needing continuous live air.
Vertical Lift Platforms
Raises and lowers heavy industrial platens using symmetric double-rod drive, relying on the fail-safe collet to arrest the load instantly if air pressure drops or an E-stop is triggered.
Press Ejection Stations
Uses the rear rod extension for mounting a flag cam to trigger DMSE electronic sensors, while the front rod provides 3681 N of push and pull force for part ejection.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X500S the Right Cylinder?
Choose this 100 mm bore double-rod cylinder when your application requires symmetric both-way drive force and a robust 5500 N fail-safe holding capacity. If your load demands less force, the 80 mm bore offers 2268 N at 0.5 MPa with a 3600 N hold; stepping up to the largest 125 mm bore yields 5734 N at 0.5 MPa and an 8600 N hold. Always verify your static load is under 5500 N.
Engage the lock only after the rod completely stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. Operating pressure is capped at 0.7 MPa. For this 500 mm stroke, use an external guide rail to prevent side-load wear on the seals and rod bearings.
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 BSED100X500S FAQ
The double-rod drive force is equal both ways: 3681 N at 0.5 MPa and 5153 N at 0.7 MPa (a maximum of 525 kgf). The integrated fail-safe rod lock provides a separate bidirectional static holding force of 5500 N with no live air.
The lock is spring-applied and air-released via the dedicated G1/8 port. You must release it only after the rod has completely stopped and both piston sides are pressure-balanced, allowing at least 0.5 seconds for the collet to disengage before moving.
