Y-bearing units

Y-bearing units for high temperatures have a grey cast iron housing and are available in three different designs as
  • plummer (pillow) block units (fig 1)
  • flanged units with square housing and four bolt holes (fig 2)
  • flanged units with oval housing and two bolt holes (fig 3)
The Y-bearings incorporated are described in the previous section.
The cast housings of the units are interchangeable with those of the standard Y-bearing units except for a few sizes where some dimensions differ slightly. The housings are zinc coated and yellow chromated to provide better protection against corrosion.
The housings do not have a grease nipple as the incorporated bearings are lubricated for life. The housing bore is coated with a lubricating paste and the tolerances are such that initial misalignment can be accommodated, even at high temperatures.
