The top-entry agitator LRK is used to meet rigorous requirements regarding both bearing and smooth-running. In addition to its rigid cast steel bearing housing, this agitator series features a coupling housing with an elastic coupling to connect the drive with a shaft journal. Thus, the LRK can be supplied as a fast running agitator with long shafts. The agitator shaft is borne within the bearing housing and is divided by a flanged coupling below the mounting flange.
