Cast iron flanged housings

Cast iron flanged housings are used in the ball bearing unit series listed in:
Cast iron flanged housings enable ball bearing units to be relubricated through a grease fitting. This makes them especially suitable for bearing arrangements that operate under any of the following conditions:
  • high levels of contamination
  • high speeds
  • high temperatures
  • relatively heavy loads
Three different housing designs are available:
  • FY(J) series (fig. 1)
    → square flange
    → four round bolt holes
  • FYT(J) and FYTB series (fig. 2)
    → oval flange
    → two round bolt holes
  • FYC series (fig. 3)
    → round flange
    → four round bolt holes

End covers

To protect the bearing arrangement at the end of a shaft, and to avoid the possibility of an accident caused by an exposed shaft end, cast iron flanged housings in the FY and FYTB series are able to accommodate ECY series end covers (fig. 4). End covers are accessories and must be ordered separately. The designations together with the distance A5 that the end cover protrudes from the housing (fig. 5) are listed in the relevant product tables:

The complete assortment of end covers for insert bearing housings and units is listed in the product table .
End covers are made of polypropylene (PP), have good resistance to most chemicals and can withstand operating temperatures up to 100 °C (210 °F). They are mounted by snapping them into the recess of the housing.
