INA FLAN47-MST Flanschlagergehäuse

As a bearing housing, this housing accepts a separately selected bearing insert. The specification table holds the available technical details in full. Instead of a cast body, a drawn sheet part carries the insert here — the choice favours weight and section height, not rigidity. In sheet steel too, the flanged housing remains a housing part without a raceway of its own; it holds the separately selected bearing insert and transfers its force through the flange into the surrounding structure.

The formed sheet part is lighter than a cast housing, takes up less height and can be produced in quantity with consistent geometry; it damps less and is less rigid than grey cast iron, which is why it is intended for moderately loaded bearing positions and light drives. The ratings of the bearing position come from the insert, so bore diameter, bolt pattern and flange form are to be matched with the intended insert.

Because the sheet construction is more compliant, an uneven or out-of-square mounting face affects alignment more strongly than it would on a cast housing. Protection against contamination and corrosion is to be ensured through the surroundings or supplementary sealing elements.
