These flanged bearing housings are designed
to use self aligning ball bearings series 12 K and 22 K or spherical roller
bearings

series 222 K. Fixing of the bearings on the
shaft is by means of an adapter sleeve.

HFB supplies these housings for through
shaft (Arrangement B) and as an end bearing housing with end cover (Arrangement

A).

Flanged bearing housings series 7225.. are
sealed with felt strip and designed for grease lubrication. A R1/8" grease
hole is

incorporated in the housing for eventual
later greasing. For shaft diameters 20 - 60 the housing is supplied in a
triangular

form with 3 mounting bolts, for the shaft
range 65 - 100 in square form with 4 mounting holes.

The bearing seat in the housing is designed
with a bore tolerance H7 and for a floating bearing. Locating bearing

arrangements are obtained by fitting the
matching fixing rings between the housing shoulder and bearing outer race.
