INA Lagerhus, Gjutjärn, ID 20 mm ID, centrumhöjd 33.3 mm, L 65 mm, D 43.7 mm

INA housing units are available as plummer block, flanged and take-up housing units in numerous different designs. The units are ready-to-fit and comprise INA cast iron or sheet steel housings in which INA radial insert ball bearings are fitted. In order to ensure function and reliability under all operating conditions, the bearings and housings are matched to each other. Due to the spherical outside surface of the bearing outer ring and the concave housing bore, housing units can compensate for static angular misalignment of the shaft. The units are used predominantly as locating bearings, but are also suitable as non-locating bearings under low loads and speeds. The housings are screw mounted on the adjacent construction. Less stringent tolerances are sufficient for the screw mounting surfaces.
