Plummer block or Pedestal bearing is used for long shafts, requiring intermediate support, especially when the shaft cannot be introduced in the bearing end-wise. It consists of a pedestal or base, a cap and a bush, split into two halves, called ‘bearing brasses’. The split parts used in the assembly, facilitate easy assembly and periodical replacement of the worn-out brasses. After placing the journal on the lower half of the bush, kept in the base, the upper half of the bush is placed and the cap is then fixed to the pedestal, by means of two bolts. Flanges are provided at either end of the bush, to prevent its axial motion. The rotary motion of the bush is prevented by a snug provided at the bottom of the lower brass, fitting into a corresponding hole in the base.
