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 cylinÂdrical 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.

                              Application
A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment.
Typically these bearings support a rotating shaft in the [bore] of the inner ring that may be misaligned in respect to the outer ring.Â
The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers.
Despite what their name may imply,Spherical roller bearings are not truly spherical in shape. The rolling elements of spherical
roller bearings are mainly cylindrical in shape,But have a profile that makes them appear like cylinders that have been slightlyover-inflated.
Spherical roller bearing used in countless industrial applications, where there are heavy loads, moderate speedsand possiblymisalignment.
