      We are doing some design work and as part of it need to work out a way to have a quick release lock on a shaft that is moving in and out of a cylinder whilst supported by a bush. We need a lock that can be mounted on or in the cylinder that can lock the shaft at any set position. You need to be able to turn the lock on and off quickly so the shaft can move freely and it most lock in both directions. Looking for an off the shelf part made from plastic or aluminium to keep weight down.

      I have found cylinder locking collars but they only lock in one direction. Preferably would like to hook the lock up so it can be cable activated

      Any thoughts

      Why not use a clamp or hydraulic coupling? ... You can design something single acting with spring return, there is also lots of commercial material. A greeting.

      Thanks for this. Where did you get the picture as that looks perfect? Any idea who does hydraulic couplings commercially as we would like to use an off the shelf product. Did a google search but nothing like this came up

      Hello,

      I'm glad you like it. You can find this material on this website (ETP-Octopus) but there is much similar material, looking for shaft-hub connections. A greeting.

      Without too much information as to the size of the shaft, loads, speeds etc, Festo pneumatics have a range of locking cylinders.
