Composite flanged housings

Composite flanged housings are used in Y-unit series listed in:

Composite flanged housings are made of leightweight glass fibre reinforced PA6 and have no relubrication feature. For durability, mechanical strength and thermal stability they are reinforced with a "moulded in" steel coil.

Composite flanged Y-bearing units are particularly well-suited for applications with relatively high speeds, moderate loads and where reliability and minimal maintenance are key factors.
Two different housing designs are available:
  • FYK series (fig. 1)
    → square flange
    → four round bolt holes
  • FYTBK series (fig. 2)
    → oval flange
    → two round bolt holes

The bolt holes are reinforced with chromium6+ free zinc-coated steel inserts.

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, composite flanged housings are able to accommodate ECY series end covers (fig. 3). 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. 4) are listed in the product tables:

The complete assortment of end covers for Y-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.
