Q5 -   What should I care before installation?

 A   - Normally, the preservative with which new bearings are coated before leaving the factory does not need to be

        removed; it is only necessary to wipe off the outside cylin­drical surface and bore, if the grease is not compatible

        with the preservative, it is necessary to wash and carefully dry the bearing.

      -Bearings should be installed in a dry, dust-free room away from metal working or other machines producing

        swarf and dust.

Q6 - How to stock and maintenance my bearings right? 

 A   - Do not store bearings directly on concrete floors, where water can condense and collect on the bearing;

      -Store the bearings on a pallet or shelf, in an area where the bearings will not be subjected to high humidity

       or sudden and severe temperature changes that may result in condensation forming;

      -Always put oiled paper or, if not available, plastic sheets between rollers and cup races of tapered roller bearings.
