Airtac BSED Clamping Double Acting Cylinder BSED100X900S
The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED100X900S combines a double-rod ISO 15552 cylinder — a Ø25mm rod out BOTH ends for equal force both directions — with an integrated spring-applied, air-released ROD LOCK that holds up to 5500 N in either direction if air is lost. Ø100mm bore, 900mm stroke, PT1/2 ports, G1/8 lock-release.

About the Airtac BSED Clamping Double Acting Cylinder BSED100X900S
The AirTAC BSED100X900S is a double-acting, double-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A rod exits both ends, delivering equal drive force of 3681 N each way at 0.5 MPa. The fail-safe collet mechanism provides a 5500 N static holding force with no live air required.
This 100 mm bore unit operates at 0.15-0.7 MPa with a PT1/2 cylinder port and a dedicated G1/8 release port. Equipped with a magnet (-S), it supports CMSE reed and DMSE electronic sensors. The extruded aluminum barrel design eliminates external tie rods while maintaining ISO 15552 mounting interchangeability.
Double Rod + 5500 N Rod Lock (Ø100mm)
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 BSED100X900S 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 M20×1.5 both ends. Mounting (BSED): Basic, LB, FA, TC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
Theoretical Output Force (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa (max) | 5154 N |
| Max drive (@0.7 MPa) | 526 kgf |
A rod exits both ends, so force is equal on extend and retract. Drive force is separate from the 5500 N static lock holding force. Size with a safety margin.

Where the Airtac BSED Clamping Double Acting Cylinder BSED100X900S Is Used
Vertical Lift Jigs
Holds elevated 5000 N vertical lifting jigs securely in place during air loss, while the 5153 N equal both-way drive powers rapid up/down cycling.
Pallet Stops
Arrests heavy pallet conveyor flows using the 5500 N fail-safe collet, utilizing the twin rods to mount dual stop flags without rotational twist.
Indexing Chucks
Drives 900 mm chuck actuation with identical force in both directions, locking the 525 kgf payload instantly when the machine E-stop trips.
Is the Airtac BSED Clamping Double Acting Cylinder BSED100X900S the Right Cylinder?
Select this 100 mm bore model when an application demands both symmetric pushing/pulling force and intermediate fail-safe holding. Verify your static load does not exceed the 5500 N holding capacity. If you need less force, the 80 mm bore offers 2268 N at 0.5 MPa and 3600 N holding; for heavier loads, the 125 mm bore provides 5734 N at 0.5 MPa and 8600 N holding.
At 900 mm stroke, use a guide rail to prevent side-load binding on the seals. Engage the lock only after the rod completely stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. Replacement requires matching the 100 mm bore, 900 mm stroke, PT thread, and Basic/LB/FA/TC mounting.
Quick checklist
- ✓ Need both symmetric force AND fail-safe hold?
- ✓ Load to hold ≤ 5500 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 BSED100X900S FAQ
The integrated spring-applied collet instantly clamps the rod, providing a 5500 N bidirectional static hold with no live air. It is a fail-safe holding lock, not a dynamic brake, so engage it only after the rod stops.
The drive force is equal both ways at 3681 N (0.5 MPa) and 5153 N (0.7 MPa), with a maximum drive of 525 kgf. The static holding force of the lock is 5500 N. Release the lock via the G1/8 port only when both sides are pressure-balanced.
