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.

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.
