About the Airtac BSED Clamping Double Acting Cylinder BSED50X225
The AirTAC BSED50X225 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 825 N each way at 0.5 MPa and 1154 N at 0.7 MPa. The bidirectional collet lock provides a 1400 N static holding force to secure the load with no live air.
This 50 mm bore unit uses a PT1/4 cylinder port and a dedicated G1/8 release port. It features a 20 mm rod with an M16x1.5 thread, 30 mm adjustable air cushions at both ends, and operates at 30-800 mm/s. This SKU is supplied without a magnet, so CMSE or DMSE position sensors cannot be used.
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 BSED50X225 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 BSED50X225 Is Used
Mid-Stroke Machining Clamps
Uses the 825 N equal both-way force to clamp parts from both directions, while the 1400 N fail-safe lock holds the position securely during machining.
Pallet Lift-and-Stop Stations
Lifts pallets with identical push and pull force, engaging the collet lock to hold the 1400 N load safely when air pressure is removed.
Symmetric Transfer Arms
Drives a transfer arm in both directions at 30-800 mm/s, using the rear rod for anti-rotation tooling and the lock to prevent drift.
Is the Airtac BSED Clamping Double Acting Cylinder BSED50X225 the Right Cylinder?
Select this 50 mm bore model when an application requires symmetric both-way force and a fail-safe hold up to 1400 N. If your load demands less force, the 40 mm bore offers 528 N at 0.5 MPa and a 900 N hold; if you need more, the 63 mm bore provides 1402 N at 0.5 MPa and a 2200 N hold. Always confirm your load is within the 1400 N static holding limit.
Engage the lock only after the rod completely stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. With a 225 mm stroke, use guide rails to manage side loads and prevent binding. Replacement parts must match the 50 mm bore, 225 mm stroke, PT1/4 port, and Basic/LB/FA/TC mounting choice.
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 BSED50X225 FAQ
The integrated spring-applied collet immediately clamps the rod, providing a 1400 N static holding force to maintain position. It is a fail-safe hold, not a dynamic brake, so it must engage only after the rod stops.
The double-rod drive force is equal both ways: 825 N at 0.5 MPa and 1154 N at 0.7 MPa (max 118 kgf). The separate static holding force of the rod lock is 1400 N.
