Airtac BSED Clamping Double Acting Cylinder BSED100X50S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X50S 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, 50mm stroke, PT1/2 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED100X50S
The AirTAC BSED100X50S 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 and speed in both directions. You get about 3681 N of drive force each way at 0.5 MPa, and a robust 5153 N at the 0.7 MPa ceiling.
The integrated collet lock provides a 5500 N bidirectional static holding force with no live air required. If pressure drops or an E-stop trips, the rod is clamped securely at its position. The lock uses a separate G1/8 release port and is a static holding device, not a dynamic brake. Engage it only after the rod stops, release it only when both piston sides are pressure-balanced, and allow at least 0.5 seconds for the transition.
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 BSED100X50S 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 BSED100X50S Is Used
Heavy Mold Clamping
Secures large injection molds using 5153 N of equal both-way drive, while the 5500 N fail-safe collet lock holds the heavy assembly firmly in place during air loss.
Overhead Z-Axis Platen
Lifts and lowers a machining platen with symmetric force on both strokes. The spring-applied lock engages statically to prevent drops when air pressure is removed.
Pallet Indexing Gate
Drives a heavy diverting gate on a conveyor line with equal push and pull power. The rear rod carries a cam for position feedback, and the lock holds the gate open safely.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X50S the Right Cylinder?
Select this 100 mm bore model when your application requires symmetric both-way force and fail-safe positioning up to 5500 N. If your load exceeds 5500 N, you must step up to the 125 mm bore (5734 N at 0.5 MPa, 8600 N holding force). If your drive or hold requirements are lower, step down to the 80 mm bore (2268 N at 0.5 MPa, 3600 N holding force). Always verify your load is safely below the 5500 N static limit. For man-rated or overhead loads, add external safety-rated controls.
When ordering a replacement, match the 100 mm bore, 50 mm stroke, PT1/2 cylinder port, and your required mounting style (Basic, LB, FA, or TC). This unit includes the -S magnet for position sensing via CMSE reed or DMSE electronic sensors. The 25 mm rod uses an M20x1.5 thread, and the extruded aluminum barrel has no external tie rods for a clean ISO 15552 interchangeability profile.
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 BSED100X50S FAQ
The double-rod design provides equal drive force both ways: 3681 N at 0.5 MPa and 5153 N at 0.7 MPa (max 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 a dedicated G1/8 port. To release it safely, ensure both piston sides are pressure-balanced, apply unlocking pressure between 0.15 and 0.7 MPa, and allow at least 0.5 seconds before moving the rod. Never use it as a dynamic brake.
