About the Airtac BSED Clamping Double Acting Cylinder BSED100X100S
The AirTAC BSED100X100S 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 symmetric annulus area ensures identical push and pull dynamics, while the rear rod provides a stable mounting point for tooling or position flags and resists rotation.
The fail-safe collet mechanism provides a bidirectional static holding force of 5500 N with no live air required. If air pressure drops or an E-stop trips, the lock engages instantly to secure the 25 mm rod. It uses a dedicated G1/8 release port, and the adjustable air cushions at both ends are for end-of-stroke deceleration only—the mechanical collet is the true holding device.
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 BSED100X100S 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 BSED100X100S Is Used
Overhead Lift Stations
Secure vertical lifting platforms holding heavy dies. The 5153 N both-way drive moves the load, while the 5500 N spring-applied lock holds it safely if compressed air fails.
Multi-Tool Machining
Mount opposing tools on the dual rods for simultaneous operations. Equal 3681 N force at 0.5 MPa both ways ensures balanced cutting or clamping in either direction.
Heavy Pallet Indexing
Position heavy pallets on a machining line. The fail-safe collet locks the 25 mm rod instantly during an E-stop, preventing drift while the system resets.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X100S the Right Cylinder?
Select this 100 mm bore cylinder when your application requires symmetric both-way force up to 5153 N alongside a robust 5500 N fail-safe hold. If your load falls below 3175 N of drive force and 3600 N of holding force, step down to the 80 mm bore. If you need to exceed 5153 N drive and 5500 N hold, step up to the 125 mm bore, which provides 5734 N at 0.5 MPa and an 8600 N static hold. Always confirm your load stays within the 5500 N holding limit and engage the lock only after the rod completely stops.
To release the clamp safely, pressure-balance both piston sides first, then apply air to the G1/8 release port, allowing at least 0.5 seconds before moving. This 100 mm bore features a PT1/2 cylinder port, M20x1.5 rod thread, and a magnetic piston (-S) for use with CMSE reed or DMSE electronic sensors. Mounting options include Basic, LB, FA, and TC brackets. For this 100 mm stroke, standard guide rules apply, but always support side loads with external bearings rather than the rod.
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 BSED100X100S FAQ
The double-rod drive force is equal 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 safely, pressure-balance both sides of the piston first, then apply 0.15-0.7 MPa to the release port, and wait at least 0.5 seconds before commanding cylinder motion.
