Airtac BSED Clamping Double Acting Cylinder BSED63X25
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED63X25 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 2200 N in either direction if air is lost. Ø63mm bore, 25mm stroke, PT3/8 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED63X25
The AirTAC BSED63X25 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 1402 N each way at 0.5 MPa and 1962 N at 0.7 MPa. The rear rod is ideal for mounting flags or anti-rotation tooling.
This fail-safe collet lock delivers a 2200 N static holding force without consuming live air. It engages only after the piston stops and releases via a dedicated G1/8 port when cylinder pressures are balanced. This 63 mm bore unit features a PT3/8 cylinder port, a 20 mm rod with an M16x1.5 thread, and 36 mm adjustable air cushions at both ends. This non-magnet SKU lacks position sensors.
Double Rod + 2200 N Rod Lock (Ø63mm)
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 BSED63X25 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 (Ø63mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa (max) | 1962 N |
| Max drive (@0.7 MPa) | 200 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 2200 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED63X25 Is Used
Gripper Actuation
Drives a short-stroke clamping jaw with 1962 N of equal both-way force, while the 2200 N rod lock holds the part securely during machine cycle pauses.
Vertical Lift Stops
Lifts a light vertical load symmetrically from both ends and engages the fail-safe collet to prevent dropping if air pressure drops below 0.7 MPa.
Anti-Rotation Indexing
Uses the rear rod for a cam follower to resist rotation, locking the 25 mm stroke precisely in place with 2200 N of static holding power.
Is the Airtac BSED Clamping Double Acting Cylinder BSED63X25 the Right Cylinder?
Select this 63 mm bore model when an application demands symmetric both-way force alongside a 2200 N static hold. If your load requires less force, the adjacent 50 mm bore provides 825 N at 0.5 MPa and a 1400 N hold. For heavier loads, step up to the 80 mm bore, offering 2268 N at 0.5 MPa and a 3600 N hold. Always verify your load stays within the 2200 N holding limit.
Because the 25 mm stroke is very short, side-load risks are minimal, but always ensure rigid mounting using the Basic, LB, FA, or TC interface. Engage the lock only after the rod stops, and allow at least 0.5 s for release after balancing piston pressures. To add position sensing, specify the -S magnet option for CMSE or DMSE sensors.
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 2200 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 BSED63X25 FAQ
The double-rod design provides equal drive force in both directions: 1402 N at 0.5 MPa and 1962 N at 0.7 MPa, with a maximum drive force of 200 kgf. The integrated fail-safe rod lock provides a separate static holding force of 2200 N with no live air required.
The spring-applied collet lock must only be engaged after the rod stops moving. To release it safely, ensure both piston sides are pressure-balanced, apply air to the dedicated G1/8 release port, and allow at least 0.5 seconds before commanding cylinder motion.
