Housing units

INA housing units are available in many different designs as plummer block, flanged and take-up housing units. The ready-to-fit units comprise INA cast iron or INA sheet steel housings in which the INA radial insert ball bearings are integrated. In order to ensure correct function and operational reliability in all operating conditions, the bearing and housing are matched to each other.

Due to the spherical outside surface of the bearing outer ring and the spherical housing bore, INA housing units can compensate for static angular misalignment of the shaft; see Compensation of misalignments.

The units are used predominantly as locating bearings, but can also be used as non-locating bearings under low loads and speeds.

The housings are screw mounted on the adjacent construction. Less demanding tolerances are sufficient for the screw mounting surfaces.
