Abstract
A sprocket assembly, particularly adapted for use in wastewater settling tanks, is provided, which assembly is adapted to be supported on a shaft having a longitudinal axis. The sprocket assembly includes a polymeric sleeve adapted to be mounted on the axially extending shaft, the sleeve including a low friction bearing surface formed of ultra high molecular weight polyethylene. The sprocket assembly further includes a sprocket wheel adapted to be mounted on the bearing surface of the sleeve for rotation relative to the sleeve about the longitudinal axis of the shaft. Seals are further provided to inhibit the introduction of grit between the sleeve and the sprocket wheel.
