Airtac BSED Clamping Double Acting Cylinder BSED50X175
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED50X175 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, 175mm stroke, PT1/4 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED50X175
The AirTAC BSED50X175 is a double-acting, double-rod ISO 15552 profile cylinder with an integrated spring-applied, air-released rod lock. A rod exits both ends, providing equal drive force in both directions—about 825 N each way at 0.5 MPa. The internal collet delivers a bidirectional static holding force of 1400 N, clamping the rod securely whenever air pressure is lost.
This unit features a 175 mm stroke, a Ø20 mm rod with an M16x1.5 thread, and a PT1/4 cylinder port. The lock uses a separate G1/8 release port and requires 0.15-0.7 MPa to disengage. Because this SKU lacks the -S magnet option, it does not support position sensing.
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 BSED50X175 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 BSED50X175 Is Used
Overhead Z-Axis Lift
Holds a 1400 N vertical load securely on air loss, while the double-rod resists rotation during guided lifts.
Pallet Stopper
Provides 825 N both-way force to index and retract a stop gate, locking instantly when E-stops trip.
Symmetric Press Tool
Uses the equal push and pull thrust of 1154 N at 0.7 MPa to form parts from both directions without stroke offset.
Is the Airtac BSED Clamping Double Acting Cylinder BSED50X175 the Right Cylinder?
Select this 50 mm bore when you need 825 N of symmetric thrust both ways and a 1400 N fail-safe hold. If your load requires less force, step down to the 40 mm bore (528 N drive, 900 N hold); if you need more, step up to the 63 mm bore (1402 N drive, 2200 N hold). Always 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 replacement, match the 50 mm bore, 175 mm stroke, PT port, and mounting choice (Basic, LB, FA, or TC).
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 BSED50X175 FAQ
The spring-applied collet engages instantly, providing a 1400 N static holding force to keep the rod at position. It is a fail-safe hold, not a dynamic brake, so engage it only after the rod stops.
The double-rod design delivers equal force both ways: 825 N at 0.5 MPa and 1154 N at 0.7 MPa (max 118 kgf). The integrated rod lock adds a 1400 N static holding force.
