Housing Bearings

Miba housing bearings include pedestal, end flange, and center flange bearings. The hydrodynamic bearings are supplied in halves and spherically seated in the housing. ZF and ZM are flanged onto the application, while ZR or US Design pedestal bearings stand in front of it. The housing design allows a convenient installation due to the smart modular system, which guarantees an easy adaptation of the bearing to your applications.
