OX series tool changers allow to change fast and easily any robot end of arm tooling. Locking and unlocking are performed through metal spheres running on special bearings, with a system patented by Star Group. Thanks to their superduralumin structure, not only are they very strong, but also incredibly light. Anti-fall system prevents the chuck side from falling even in case of air supply interruption, while the air locking systems closes air ways and tool changers do not suffer any air loss. The loadable weight spans from 3 to 80 kilograms, making OX series applicable to every need. They can be used on every cartesian robots, of any supplier.
