The AirTAC Airtac BSED Clamping Double Acting Cylinder BSED63X900 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, 900mm stroke, PT3/8 ports, G1/8 lock-release.
The AirTAC BSED63X900 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 1402 N each way at 0.5 MPa. The extruded aluminum barrel has no external tie rods, and the rear rod can mount a flag or resist rotation.
The fail-safe collet lock provides a 2200 N static holding force without live air. It engages bidirectionally when pressure drops or an E-stop trips. A separate G1/8 release port controls the lock, and the lock is a static hold, not a dynamic brake. This SKU has no magnet, so position sensors are not supported.
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 BSED63X900 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.

| 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.

Thread: PT (blank) / G. Mounting (BSED): Basic, LB, FA, TC. Related: SED (double rod, no lock), BSE (single-rod rod lock). Sensors CMSE/DMSE fit magnetic BSED.
Holds a vertical lifting platform securely mid-stroke with 2200 N of static force if air drops, while the double-rod provides equal 1402 N lift and lowering force at 0.5 MPa.
A rod extending from both ends actuates a heavy stop gate and a rear cam flag simultaneously. The lock holds the 900mm stroke firmly against flowing pallet impacts.
Traverses a 900mm distance to clamp large parts. The fail-safe collet maintains position during machining cycles, resisting 1962 N of push force at 0.7 MPa.
Select this 63mm bore when your application needs symmetric force and failsafe holding up to 2200 N. If your load requires less force, step down to the 50mm bore, which provides 825 N at 0.5 MPa and a 1400 N hold. If you need more drive or hold, step up to the 80mm bore, offering 2268 N at 0.5 MPa and a 3600 N hold. Operating pressure is capped at 0.7 MPa.
Ensure the load to hold is under 2200 N. Engage the lock only after the rod stops, and release it only when both piston sides are pressure-balanced, allowing at least 0.5 seconds. Because the 900mm stroke is long, use external guide rails to prevent side-load damage. This cylinder uses a PT3/8 port, a 20mm rod with an M16x1.5 thread, and a 36mm cushion length.
Quick checklist
The spring-applied collet engages instantly, providing a 2200 N bidirectional static holding force to keep the rod at its position. It is a fail-safe static hold, not a dynamic brake, so it must only engage after the rod stops.
The drive force is equal both ways: 1402 N at 0.5 MPa and 1962 N at 0.7 MPa, with a max drive of 200 kgf. The static holding force is 2200 N. Speed is 30-800 mm/s. To release the lock safely, balance pressure on both piston sides via the G1/8 port and wait at least 0.5 seconds.
