Airtac BSED Clamping Double Acting Cylinder BSED50X150
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED50X150 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, 150mm stroke, PT1/4 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED50X150
The AirTAC BSED50X150 is a double-acting, double-rod ISO 15552 profile cylinder featuring a spring-applied, air-released rod lock. A rod exits both ends, providing equal thrust and speed in both directions. It delivers 825 N of drive force each way at 0.5 MPa and 1154 N at 0.7 MPa.
The integrated collet lock delivers a 1400 N static holding force, securing the load bidirectionally with zero live air. Because this SKU lacks the -S magnet option, it does not support CMSE or DMSE position sensors. The lock uses a separate G1/8 release port, and the cylinder ports are PT1/4.
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 BSED50X150 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 BSED50X150 Is Used
Overhead Z-Axis Lifts
Holds a 1400 N vertical load safely if air pressure drops, while the dual rods provide equal 1154 N lifting and lowering force.
Pallet Transfer Stops
Uses the rear rod end for a cam flag to confirm position, locking the 825 N stroke securely during pallet indexing.
Symmetric Tooling Jigs
Equal push and pull force prevents jig drift, with the fail-safe collet locking the 20 mm rod instantly on E-stop.
Is the Airtac BSED Clamping Double Acting Cylinder BSED50X150 the Right Cylinder?
Choose this 50 mm bore when an application requires symmetric force alongside a 1400 N fail-safe hold. If your load demands less thrust, the 40 mm bore offers 528 N at 0.5 MPa and a 900 N hold. For heavier loads, step up to the 63 mm bore, which provides 1402 N at 0.5 MPa and a 2200 N hold.
Always 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. To replicate this exact unit, match the 150 mm stroke, PT1/4 port, and your preferred mounting from the Basic, LB, FA, or TC set.
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 BSED50X150 FAQ
The spring-applied collet engages instantly, providing a 1400 N static holding force to keep the load in place without live air. It is a fail-safe lock, not a dynamic brake, so engage it only after motion stops.
The double-rod design delivers equal drive force both ways: 825 N at 0.5 MPa and 1154 N at 0.7 MPa, with a maximum drive of 118 kgf. The integrated fail-safe lock provides a separate 1400 N static holding force.
