The AirTAC Airtac BSE Clamp Standard Cylinder BSE63X300 is a genuine double-acting ISO 15552 cylinder with an integrated spring-applied, air-released ROD LOCK. If air is cut or an E-stop is hit, the collet clamps the Ø20mm rod and holds up to 2200 N in either direction — no drift. Ø63mm bore, 300mm stroke, PT3/8 cylinder ports, G1/8 lock-release port.
The AirTAC BSE63X300 is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a 2200 N bidirectional static holding force, ensuring suspended loads remain exactly where they stopped if air pressure drops. Operating pressure is capped at 0.7 MPa, and the lock mechanism utilizes a clamping collet rather than relying on the adjustable air cushions at both ends.
This 63 mm bore, 300 mm stroke unit uses a PT3/8 cylinder port alongside a dedicated G1/8 release port. Because it is built on the SE body, standard SE mounting accessories fit perfectly, except for FTC. This specific SKU lacks a magnet, so it does not support CMSE or DMSE position sensors.
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE63X300 holds its position in both directions when air is lost, exhausted or an E-stop trips. Apply 0.15–0.7 MPa to the G1/8 release port to unlock. Engage the lock only after the rod has stopped (it is not a dynamic brake), and release only when the pressures on both sides of the piston are balanced. Allow at least 0.5 s for full release before moving.

Secures a vertical pallet lift carrying 150 kg. The 2200 N holding force prevents back-driving if air exhausts, while the 2182 N push at 0.7 MPa handles the lift drive.
Holds a machining fixture in place during an E-stop. The fail-safe collet locks the 20 mm rod instantly, keeping the workpiece rigid without consuming live air.
Acts as a mid-conveyor stop gate. The lock holds the 300 mm extended rod against repeated impacts, surviving 0.15-0.7 MPa operating pressure variations.
Verify your load requires a holding force of 2200 N or less. If you need less drive power, the 50 mm bore neighbor offers 982 N push at 0.5 MPa and a 1400 N hold. If you need more, step up to the 80 mm bore for 2513 N push at 0.5 MPa and a 3600 N hold. Always engage the lock only after the rod stops, and release it only when piston pressures are balanced, allowing at least 0.5 s before moving.
When replacing, match the 63 mm bore, 300 mm stroke, PT3/8 port, and mounting style. At 300 mm stroke, use a guide rail to prevent excessive side loads on the rod. This unit has no magnet, so skip sensor specs.
Quick checklist
The rod lock is spring-applied and air-released. If air is lost or exhausted, the collet instantly clamps the rod, providing a fail-safe bidirectional static holding force of 2200 N without live air.
The drive force is separate from the hold. At 0.5 MPa, push is 1559 N and pull is 1402 N. At 0.7 MPa, push is 2182 N, yielding a max drive of 222 kgf. The static holding force is 2200 N.
