Airtac BSED Clamping Double Acting Cylinder BSED50X450
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED50X450 combines a double-rod ISO 15552 cylinder — a Ø20mm rod out BOTH ends for equal force both directions — with an integrated spring-applied, air-released ROD LOCK that holds up to 1400 N in either direction if air is lost. Ø50mm bore, 450mm stroke, PT1/4 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED50X450
The AirTAC BSED50X450 is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, providing equal drive force of 825 N each way at 0.5 MPa. The bidirectional collet lock delivers a 1400 N static holding force, securing the load safely with zero live air.
This unit uses a 20mm rod with an M16x1.5 thread, PT1/4 cylinder ports, and a separate G1/8 lock-release port. Because this 450mm stroke lacks the -S magnet option, it does not support CMSE or DMSE position sensors. Engage the lock only after the rod stops, and release it once both piston sides are pressure-balanced.
Double Rod + 1400 N Rod Lock (Ø50mm)
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 BSED50X450 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 M16×1.5 both ends. Mounting (BSED): Basic, LB, FA, TC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
Theoretical Output Force (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa (max) | 1155 N |
| Max drive (@0.7 MPa) | 118 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 1400 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED50X450 Is Used
Overhead Lift Stops
Holds vertical lifting stages securely mid-stroke with 1400 N of fail-safe force, preventing drops when compressed air is lost.
Pallet Indexing
Uses the equal 825 N both-way drive to push pallets forward and retract without re-piping, locking instantly at 450mm stroke ends.
Dual-Tool Machining
Mounts a tool on the front rod and a cam on the rear rod, utilizing anti-rotation stability and the fail-safe lock during workpiece clamping.
Is the Airtac BSED Clamping Double Acting Cylinder BSED50X450 the Right Cylinder?
Select this 50mm bore model when you need symmetric 825 N force both ways alongside a fail-safe 1400 N hold. If your load exceeds 1400 N, step up to the 63mm bore (1402 N drive at 0.5 MPa, 2200 N hold). If you need less force, the 40mm bore offers 528 N drive and 900 N hold. Operating pressure is capped at 0.7 MPa. At 450mm stroke, use an external guide to prevent side-load binding. Replacement parts must match the 50mm bore, 450mm stroke, PT port, and Basic/LB/FA/TC mounting.
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 1400 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 BSED50X450 FAQ
The spring-applied collet immediately clamps the rod, providing a 1400 N static holding force to keep the load in place. It is a fail-safe lock, not a dynamic brake, so it must only engage after the rod stops moving.
The drive force is equal both ways at 825 N at 0.5 MPa and 1154 N at 0.7 MPa, with a max drive of 118 kgf. The static fail-safe holding force of the lock is 1400 N.
