About the Airtac BSED Clamping Double Acting Cylinder BSED100X175S
The AirTAC BSED100X175S 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 drive force of 3681 N each way at 0.5 MPa and 5153 N at 0.7 MPa. The fail-safe collet mechanism provides a bidirectional static holding force of 5500 N without requiring live air.
This 100mm bore unit includes a magnetic piston (-S) for CMSE reed or DMSE electronic sensors. It features a PT1/2 cylinder port, a separate G1/8 lock-release port, and 36mm adjustable air cushions at both ends. The lock is a static holding device, not a dynamic brake, requiring a 0.5-second delay after the rod stops before engagement.
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 BSED100X175S 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 BSED100X175S Is Used
Heavy Machining Clamps
Holds heavy machining fixtures securely with 5500 N of fail-safe force while applying 5153 N of equal both-way clamping pressure.
Overhead Z-Axis Lifters
Prevents vertical drops on air loss using the spring-applied collet, while the double-rod design resists torsional load on the lift platform.
Press Feeders
Feeds heavy billets into a press with 3681 N of bidirectional drive force at 0.5 MPa, locking instantly during E-stops to protect the tooling.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X175S the Right Cylinder?
Select this 100mm bore model when an application demands both-way symmetric thrust up to 5153 N alongside a 5500 N fail-safe hold. If your load to hold is under 3600 N and your drive requirement is lower, step down to the 80mm bore, which provides 2268 N of drive force at 0.5 MPa and a 3600 N holding capacity. If you need greater thrust and holding power, step up to the 125mm bore, offering 5734 N drive force at 0.5 MPa and an 8600 N static hold.
Always verify that your load is under the 5500 N holding limit and engage the lock only after the rod completely stops. To release safely, ensure both piston sides are pressure-balanced and allow at least 0.5 seconds before moving. When replacing a unit, match the 100mm bore, 175mm stroke, PT1/2 port, and your specific mounting choice (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 BSED100X175S FAQ
The equal both-way drive force is 3681 N at 0.5 MPa and 5153 N at 0.7 MPa (max 525 kgf). The integrated fail-safe rod lock provides a bidirectional static holding force of 5500 N with no live air required.
The spring-applied collet clamps the rod instantly upon air loss or an E-stop, holding the load up to 5500 N. It is a static lock, not a dynamic brake, so you must engage it only after the rod stops. To release, pressure-balance both piston sides and allow at least 0.5 seconds.
