INA FLAN72-MSA-FA125 Flanschlagergehäuse

As a bearing housing, this housing accepts a separately selected bearing insert. The available technical details for this bearing are given in the specification table. Cast iron, sheet steel or plastic — the housing material decides load capacity, damping and suitability for wet surroundings. The loads of the insert pass into the structure through the flange face.

The housing bore is machined spherical so the insert’s convex outer ring can align itself as it is tightened; bore form and size must therefore match. Selection is accordingly driven by the bolt pattern, the flange form and the shaft diameter of the intended insert. The seating face of the structure must be flat and stiff enough, because distortion of the bolting plane preloads the bearing position and shortens its life.

Lubrication path and sealing belong to the insert, not to the housing — so for relubrication it is the accessibility of the fitted bearing that matters, not that of the housing. The corrosion-protective coating shields the surfaces against moisture without changing the dimensions of the bearing position — an alternative to a stainless version where its load ratings would not suffice.
