Airtac BSED Clamping Double Acting Cylinder BSED100X450
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X450 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, 450mm stroke, PT1/2 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED100X450
The AirTAC BSED100X450 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 collet lock provides a 5500 N static holding force, clamping the rod securely during pressure loss or E-stop events.
This extruded aluminum profile body uses a separate G1/8 release port and caps operating pressure at 0.7 MPa. The bidirectional lock is not a dynamic brake; it engages only after the rod stops and releases when piston sides are pressure-balanced. This specific SKU lacks a magnet, so CMSE or DMSE position sensors cannot be fitted.
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 BSED100X450 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 BSED100X450 Is Used
Machining Center Clamps
Holds heavy workpieces securely with 5500 N of fail-safe force during air loss, while the double-rod provides 5153 N of equal clamping and release force.
Pallet Stopper Gates
Stops and holds large inbound pallets on a conveyor; the rear rod resists rotational torque while the lock maintains position without live air.
Overhead Lift Interlocks
Prevents vertical drift on heavy lifting jigs with a 5500 N static hold. Use safety-rated controls for man-rated loads, as the lock is not a dynamic brake.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X450 the Right Cylinder?
Choose this 100 mm bore when you need both-way symmetric force and fail-safe holding up to 5500 N. If your load is lighter, step down to the 80 mm bore (2268 N at 0.5 MPa, 3600 N holding force). For heavier loads, the 125 mm bore offers 5734 N at 0.5 MPa and 8600 N holding force. Always verify the load is below 5500 N before relying on the lock.
With a 450 mm stroke, use an external guide to prevent side-load damage to the seals. To release the spring-applied collet safely, apply pressure to the G1/8 port only after balancing both piston sides, allowing at least 0.5 seconds before moving. When replacing, match the 100 mm bore, 450 mm stroke, PT1/2 cylinder port, and basic mounting setup.
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 BSED100X450 FAQ
The integrated spring-applied collet immediately clamps the rod, providing a 5500 N static holding force to maintain position. It is a fail-safe lock, not a dynamic brake, so it must engage only after the rod stops.
The double-rod design provides equal both-way drive force of 3681 N at 0.5 MPa and 5153 N at 0.7 MPa (max 525 kgf). The static fail-safe holding force of the rod lock is 5500 N.
