About the Airtac BSED Clamping Double Acting Cylinder BSED50X600S
The AirTAC BSED50X600S 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 and 1154 N at 0.7 MPa. The rear rod is ideal for mounting external tooling or position flags while resisting rotational torque.
This unit delivers a bidirectional static holding force of 1400 N. If air pressure drops or an E-stop trips, the collet clamps the 20 mm rod instantly, maintaining position without live air. The lock uses a dedicated G1/8 release port and engages only after the rod stops, distinguishing it from a dynamic brake.
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 BSED50X600S 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 BSED50X600S Is Used
Vertical Lift Stations
Lifts 118 kgf at 0.7 MPa symmetrically and locks the 20 mm rod with 1400 N of force to prevent drops during air loss.
Pallet Stopper Arms
Uses the dual rods for equal push and pull to halt 600 mm pallet travel, locking instantly via the G1/8 port during E-stops.
Mid-Stroke Machining
Holds the workpiece securely at variable positions with 1400 N static force, absorbing machining stress without live air.
Is the Airtac BSED Clamping Double Acting Cylinder BSED50X600S the Right Cylinder?
Select this 50 mm bore when your application requires symmetric both-way force and a fail-safe hold up to 1400 N. If you need less force, the 40 mm bore offers 528 N at 0.5 MPa and a 900 N hold; for heavier loads, the 63 mm bore provides 1402 N at 0.5 MPa and a 2200 N hold. Ensure your load stays under the 1400 N limit during vertical holds.
At 600 mm stroke, use a guide to prevent side loads from stressing the rod seals. To release the lock safely, pressure-balance both piston sides and allow at least 0.5 seconds before moving. Replacement parts must match the 50 mm bore, 600 mm stroke, PT1/4 cylinder port, and -S magnet option.
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 BSED50X600S FAQ
The spring-applied collet clamps the rod instantly, providing a 1400 N static holding force to maintain position without live air. It is a static lock, not a dynamic brake, so it must engage only after the rod stops moving.
The double-rod design provides equal force both ways: 825 N at 0.5 MPa and 1154 N at 0.7 MPa, with a maximum drive of 118 kgf. The static holding force of the lock is 1400 N, and the operating speed range is 30-800 mm/s.
