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. 7225(00) Flanged bearing Housings are manufactured from grey cast. On request housings manufactured from ductile iron can also be delivered. This unsplit plummer block bearing housing is designed for the use with self aligning ball bearings with an extended inner ring. The sealing rings are made from grey cast iron and fitted with a felt strips. The outer ring of the bearing is located axially by the sealing ring. The inner ring of the bearing extends approximately 1cm over each end. This prevents contact between machine parts and the housing. The movement of the inner ring as well as axial location results from the use of a set screw which is located in a groove on one side of the inner ring. TN housings are made from GG20. A high grade grease is recommended for the lubrication of these housings.
