About the Airtac BSED Clamping Double Acting Cylinder BSED40X100
The AirTAC BSED40X100 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 528 N each way at 0.5 MPa and 739 N at 0.7 MPa. The integrated collet mechanism delivers a 900 N bidirectional static holding force, securely clamping the rod with no live air required during an emergency stop or pressure loss.
This 40 mm bore unit utilizes an extruded aluminum barrel without external tie rods and includes adjustable air cushions at both ends. The lock engages via a dedicated G1/8 release port and operates safely within a 0.15-0.7 MPa pressure range. This specific SKU is configured without a magnet, meaning it does not support CMSE or DMSE position sensors.
Double Rod + 900 N Rod Lock (Ø40mm)
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 BSED40X100 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.

Theoretical Output Force (Ø40mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa (max) | 739 N |
| Max drive (@0.7 MPa) | 75 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 900 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED40X100 Is Used
Vertical Lift Holding
Ideal for vertical pick-and-place arms where the 900 N fail-safe lock prevents gravity-driven drops on air loss, while the 528 N both-way drive ensures consistent up and down movement.
Pallet Stopper Arm
Acts as a bidirectional pallet stop where the double-rod design resists rotation and the rear rod can mount a flag, while the collet holds the 739 N drive force against impacts.
Mid-Process Clamping
Secures workpieces during machining pauses, using the 900 N spring-applied hold to maintain position without continuous air supply, releasing instantly via the G1/8 port.
Is the Airtac BSED Clamping Double Acting Cylinder BSED40X100 the Right Cylinder?
Select this 40 mm bore model when your application requires symmetric both-way force and a fail-safe hold up to 900 N. If your load demands less holding capacity, the 32 mm bore offers 345 N drive force at 0.5 MPa and a 600 N hold. For heavier payloads, stepping up to the 50 mm bore provides 825 N drive force at 0.5 MPa and a 1400 N hold. Always verify your load is within the 900 N static limit.
The rod lock is a static holding device, not a dynamic brake; engage it only after the rod stops moving, and release it only when both piston sides are pressure-balanced with at least a 0.5-second delay. For this 100 mm stroke, ensure external guides are used to manage side loads and prevent binding. Direct replacement requires matching the 40 mm bore, 100 mm stroke, PT1/4 cylinder port, Basic/LB/FA/TC mounting, and non-magnet configuration.
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 900 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 BSED40X100 FAQ
The spring-applied collet mechanism automatically engages and provides a 900 N bidirectional static holding force, locking the rod in place with no live air. It is a fail-safe hold, not a dynamic brake, so it must only engage after the rod has stopped moving.
The drive force is equal both directions at 528 N @0.5 MPa and 739 N @0.7 MPa, with a maximum drive of 75 kgf. The static holding force of the lock is 900 N. The operating speed range is 30-800 mm/s, capped at a 0.7 MPa operating pressure.
