Airtac BSED Clamping Double Acting Cylinder BSED50X700
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED50X700 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, 700mm stroke, PT1/4 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED50X700
The AirTAC BSED50X700 is a double-acting, double-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A rod exits both ends, delivering equal force and speed in both directions—about 825 N each way at 0.5 MPa. The fail-safe collet clamp provides a 1400 N static holding force to secure the rod with no live air.
This extruded aluminum profile body has no external tie rods and uses a separate G1/8 release port. Because this SKU has no -S magnet, it does not support CMSE or DMSE position sensors. The 700 mm stroke requires an external guide to manage side loads and prevent binding.
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 BSED50X700 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 BSED50X700 Is Used
Z-Axis Servo Elevator
Holds a vertical lift stage securely mid-travel with 1400 N of fail-safe force, preventing a 118 kgf dynamic load from dropping when air pressure is lost.
Symmetric Transfer Shuttle
Uses the equal 825 N both-way drive at 0.5 MPa to push and pull a shuttle identically, while the rear rod mounts a flag for end-of-travel signaling.
Mid-Stroke Machining Clamp
Locks a 700 mm stroke workpiece carrier at a precise machining coordinate with no live air, ensuring the collet holds without pneumatic pressure.
Is the Airtac BSED Clamping Double Acting Cylinder BSED50X700 the Right Cylinder?
Select this 50 mm bore when you need symmetric both-way drive and a fail-safe hold up to 1400 N. If your load exceeds 1400 N, step up to the 63 mm bore (1402 N at 0.5 MPa drive, 2200 N holding force). If you need less force, step down to the 40 mm bore (528 N at 0.5 MPa drive, 900 N holding force).
Engage the lock only after the rod stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 s. For this 700 mm stroke, use an external guide to prevent side-load wear. Replacement requires matching the 50 mm bore, 700 mm stroke, PT1/4 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 BSED50X700 FAQ
The drive force is equal both ways: 825 N at 0.5 MPa and 1154 N at 0.7 MPa (max 118 kgf). The static fail-safe holding force of the rod lock is 1400 N. The lock holds the load with no live air, but is not a dynamic brake.
Release the lock only after the rod has stopped moving and both piston sides are pressure-balanced. Apply air to the separate G1/8 release port and allow at least 0.5 seconds for the collet to disengage before commanding motion.
